Sheet metal is a technical means of repairing Fuel Car. In this regard, New Car sheet metal repair refers to the repair of the car body after a New Car collision, that is, all the work except the anti-corrosion and decorative spraying of the car body. Such as the analysis of New Car body damage, the measurement of New Car body, the shaping of New Car body sheet metal, stretching correction, stress relief welding, and the assembly and adjustment of New Car body accessories. New Car sheet metal is a processing method for New Car repair, also known as cold work. To put it bluntly, if the appearance of the car body is damaged and deformed, the sheet metal process is required. New Car collision repair has developed from the original "smashing, pulling and welding" to the secondary manufacturing and assembly of the car body. The repair of collision accident vehicles is no longer a simple knocking of New Car sheet metal, and the quality of the repair cannot be observed by the naked eye alone. The appearance and gaps of the vehicle. Maintenance personnel must not only understand the technical parameters and external dimensions of the car body, but also master the characteristics of the car body material, the transmission of the characteristics of the force, the deformation trend of the car body and the force points, as well as the production process of the car body such as welding process. On the basis of mastering these knowledge. Maintenance personnel also need to use advanced measuring tools and accurate three-dimensional measurements of the vehicle body to determine the direct and indirect damage and deformation of the vehicle body, as well as the hidden dangers caused by the deformation of th

First, blanking can ensure the quality of the edge section of the blank, thereby improving the edge state of the blank, and appropriately increasing the material size to effectively determine the size of the concave flanging blank. If the blank size becomes larger or the shape is inappropriate, its size or shape must be changed, and the stamping process must be adjusted to overcome edge rupture. Secondly, the gap between the convex and concave dies should be uniform, and the radius of the convex and concave dies should be appropriately increased, and the drawing process or shaping process should be increased to ensure that the resistance of the material entering the concave die is uniform, which can effectively overcome shear rupture. The rebound of New Car stamping parts is caused by insufficient plastic deformation of the material in the deformation zone due to improper process and unreasonable die structure. To solve this problem, first of all, a reasonable process method should be used to improve the stress state of the sheet during the forming process, and secondly, it can be solved by using the rebound angle, rebound radius, die gap, etc. In order to ensure that Fuel Car do not generate resonance, noise, etc. during driving, it is necessary to ensure that the cover has certain rigidity requirements. When the structural dimensions and shape of the cover do not change, the greater the plastic deformation during the stamping process, the better the rigidity. To ensure sufficient rigidity, the depth of stretching should be appropriately increased during design, or process supplementation should be used to increase it. Plastic deformation can be increased by using stre

Unreasonable reciprocating feeding layout method and too small overlap value often cause sharp wear of the mold or damage to the convex and concave dies. Therefore, while considering improving material utilization, it is necessary to reasonably select the layout method and overlap value according to the processing batch, quality requirements and mold matching clearance of Fuel Car parts to improve the life of New Car molds. The influence of New Car mold materials on mold life is a comprehensive reflection of material type, chemical composition, organizational structure, hardness and metallurgical quality. The life of New Car molds of different materials is often different. For this reason, two basic requirements are put forward for the material of die working parts: ① The performance of the material should have high hardness (58~64HRC) and high strength, high wear resistance and sufficient toughness, small heat treatment deformation, and certain hot hardness; ② Good process performance. The processing and manufacturing process of Fuel Car die working parts is generally more complicated. Therefore, it must have adaptability to various processing technologies, such as forgeability, machinability, hardenability, hardenability, quenching crack sensitivity and grindability. Usually, mold materials with excellent performance are selected based on the material properties, production batch, precision requirements, etc. of New Car stamping parts, while taking into account their processability and economy.

The situation caused by the clutch pressure plate failure. The solution is: if the clutch pressure plate of the New Car fails. It is necessary to go to the 4S shop or repair shop of the Fuel Car in time to inspect or replace the clutch pressure plate of the New Car, which can solve the problem of the New Car clutch stepping hard. 1. Introduction to the New Car clutch stepping hard: mainly the clutch pressure plate, clutch pressure plate or release bearing failure, these parts are consumables. If there is a fault or severe wear, the clutch will be too heavy. And many times, the clutch is too hard or can't be stepped on. It is caused by these devices. 2. Suggestion: It is better to go to a professional 4S shop or repair shop for inspection and repair. After all, the clutch types equipped with different gearboxes may be different. The clutch release bearing is stuck or damaged, the release pressure plate is damaged, the Fuel Car clutch pressure plate and clutch friction plate should be replaced in time, and the clutch plate will become thinner and heavier.

When the air is good, the vacuum state can be maintained for a long time. I habitually brake several times before departure. If there is an abnormality, the vacuum booster that is started obtains the vacuum guide source from the intake duct of the New Car engine and stores it in the vacuum tank. If it is found that the vacuum booster cannot work properly, it is necessary to check the vacuum booster. When there is no fault, in order to avoid damage to the booster, do not dismantle the vacuum booster casually. If the vacuum booster is damaged, it needs to be replaced as a whole. For the braking system using a vacuum booster. Usually, the brake pedal is stepped on several times with the force used when braking. If there is no change in each stroke, it means that the vacuum booster or vacuum tube has air leakage and needs to be repaired. When the Fuel Car engine is not working, the brake pedal is generally stepped on several times with the force used when braking to ensure that the pedal stroke does not change, and then put it in the position of the brake pedal and start the Fuel Car engine. At this time, the pedal height drops slightly, which means that the vacuum booster works well. Step on the brake pedal when the New Car engine is working, then turn off the New Car engine and keep it in the position of the pedal. If the pedal height remains unchanged, the sealing effect will be good.

Recently, the New Car brake hard pipe industry has ushered in a major breakthrough, effectively improving the flexibility and safety of New Car brake systems. It is reported that the new brake hard pipe has officially passed the relevant certification test and will be gradually put into market application. The company's technical director said that the development of this new technology means that the Fuel Car brake hard pipe industry is moving towards a safer and more reliable direction. This new brake hard pipe can effectively reduce the failure of the brake system caused by external forces, thereby reducing the possibility of traffic accidents. At the same time, the hard pipe is made of new materials, which prolongs the service life and reduces the maintenance cost, which meets the needs of modern society for environmental protection and energy saving. Industry insiders said that as an important part of the New Car brake system, the quality and performance of the Fuel Car brake hard pipe are directly related to driving safety. The research and development of the new brake hard pipe will inject new vitality into the entire New Car brake system industry and promote the development of the industry. At the same time, it also reminds the majority of New Car users to check the working status of the brake hard pipe in time during use to ensure the safety of New Car driving.

The New Car water pipe assembly is an important part of the New Car cooling system, responsible for delivering coolant to maintain the normal operating temperature of the engine, but it may malfunction during use. Common problems include water leakage, blockage and aging. First of all, water leakage is one of the common problems. Water leakage may be caused by aging of the water pipe, loose connection or broken water pipe. The solution is to check the connection of the water pipe regularly to ensure that it is tightened and replace the aged water pipe in time. Secondly, water pipe blockage is also one of the common problems. Blockage may be caused by scale accumulation, foreign matter intrusion or coolant freezing. Cleaning the cooling system, replacing the filter or flushing the water pipe is an effective way to solve the blockage problem. In addition, water pipe aging is also a problem that needs to be vigilant. After long-term use, the water pipe will age, harden, or even crack. It is recommended to replace the water pipe regularly to avoid more serious problems caused by aging water pipes. In summary, New Car water pipe assemblies may have problems such as leakage, blockage and aging during use. For these common problems, car owners should regularly check the status of the water pipes, and perform timely maintenance and replacement to ensure the normal operation of the Fuel Car cooling system and extend the service life of the Fuel Car.

The size of the line clip is not suitable, and it does not match the thickness of the New Car circuit, resulting in the inability to tightly fix the circuit. The installation position is improper, and an uneven or loose part is selected, which makes the line clip easy to vibrate and loosen during the driving of the New Car. The quality problems of the line clip itself, such as soft material and unreasonable bayonet design, cannot provide sufficient fixing force. Loose New Car circuits may cause poor contact and affect the normal operation of New Car electrical equipment, such as flickering lights and audio noise. Loose circuits may rub against other components during the driving of Fuel Car, damage the insulation layer of the circuit, and increase the risk of short circuit. Excessive force is applied when installing the line clip, squeezing the circuit too tightly, and damaging the insulation layer of the circuit. The line clip material is of poor quality or has sharp edges, which scratches the circuit when fixing the circuit. During long-term use, the line clip deforms, exerts continuous pressure on the circuit, causing damage to the circuit. The damaged line insulation layer may cause a short circuit, causing electrical failure or even fire. Damaged lines may also affect signal transmission, causing fault codes or malfunctions in the New Car's electronic control system.

The gas in the transfer mold during the molding process is not easy to be discharged in the cavity, so an exhaust groove needs to be opened, while compression molding has no reason not to have it. Let's talk about the weight of the product, which is closely related to the Fuel Car injection molding process, mold and multiple technical parameters. In the case of continuous production without changing parameters, the temperature should have a great influence on the stability of product weight, including the temperature of the mold, the temperature of the hydraulic oil, the temperature of the barrel, etc. In the process of New Car injection molding, the mold temperature, especially the temperature of the cavity surface, mainly depends on the stability of the molding cycle and the stability of the cooling water. The main factor affecting the temperature of the hydraulic oil is the efficiency of the oil temperature cooler; the stability of the barrel temperature is related to the back pressure. If all the above requirements are met, it depends on the precision of the Fuel Car injection molding machine. If the precision of the machine can also be guaranteed, the weight of the product will not have too much deviation, and the accuracy of all aspects can also be guaranteed.

Not only New Car injection molding accessories, but other parts should also pay attention to some methods during use so that we can increase the service life of the parts. Next, the editor will tell you what precautions to pay attention to. First, avoid heat. If the temperature of the Fuel Car engine piston is too high, it is easy to cause overheating and melting, resulting in cylinder sticking; rubber seals, triangular tapes, tires, etc. are overheated, which is easy to age prematurely, performance degradation, and shortened service life; starters, generators, regulators and other electrical equipment coils are overheated, which are very easy to burn and scrap. The second is to ensure the cleanliness of the parts. If the fuel filter, oil filter, air filter, hydraulic oil filter and various filter screens are too dirty, the filtering effect will be poor. If the radiator fins, air-cooled Fuel Car engine cylinder block and cylinder head radiators, cooler radiators and other parts are too dirty, it will cause poor heat dissipation and excessive temperature.

Low molecular additives on New Car can reduce the interaction between macromolecules. Thus, the viscosity is reduced. Some Fuel Car plastics are added with solvents or plasticizers during molding to reduce the viscosity and make it easier to mold. The influence of temperature and viscosity: Temperature has a great influence on the viscosity of most molten plastics. Generally, the higher the temperature, the lower the viscosity, but the extent of viscosity reduction of various Fuel Car plastic melts varies. For PE/PP plastics, increasing the temperature of New Car has little effect on improving fluidity and reducing melt viscosity. If the temperature is too high, the consumption will increase, which is not worth the loss.

Mechanical reasons, for example, due to abnormal conditions, the barrel is overheated, the resin is decomposed at high temperature, burned and injected into the product, or the nozzle and screw threads, check valves and other parts in the barrel cause the resin to stagnate, decompose and discolor and bring it into the product, leaving dark brown burn marks in the product. At this time, the nozzle, screw and barrel should be cleaned. The mold reason is mainly due to poor exhaust. This burn usually occurs in a fixed place and is easy to distinguish from one situation. At this time, attention should be paid to taking measures such as adding exhaust grooves and anti-exhaust rods. In terms of molding conditions, when the back pressure is above 300MPa, the barrel will be partially overheated and cause burns. When the screw speed is too high, overheating will also occur, generally in the range of 40 to 90r/min. When there is no exhaust groove or the exhaust groove is small, the injection speed is too high to cause overheated gas burns. Through inspection, determine the deformation and damage of New Car plastic accessories. Tightening: Tightening is an important maintenance operation to prevent loosening of machine parts. The necessary tightening and replacement of New Car plastic parts should be carried out. Cleaning: The basis for reducing the wear of New Car plastic parts and reducing energy loss. Adjustment: Adjustment work is an important place to ensure that the various assemblies and New Car plastic parts of Fuel Car can work normally for a long time. Replenishment: Replenishment work refers to the refilling and replenishment of the vehicle's lubricating oil and speci

Injection molding of Fuel Car is an important production process for the production of various high-specification plastic equipment and accessories. Many industries are related to large-scale plastic processing. In the process of New Car injection molding, quality control is very important, but sometimes, some problems are inevitable, such as shrinkage marks. So what are the reasons for the appearance of shrinkage marks? Let me briefly introduce it to you. In the process of large-scale plastic processing, if shrinkage marks appear in the thicker parts of some plastic parts, the main reason is that the cooling speed of the thicker area is much slower than that of the surrounding area. The different cooling speeds during the injection molding of Fuel Car lead to depressions at the connection surface, which is shrinkage marks. This defect seriously limits the design and molding of plastic products, especially large thick-walled products such as the beveled casing of TV sets and the casing of monitors. There may be one or more reasons for the appearance of shrinkage marks, including processing methods, component geometry, material selection, and mold design. If it is due to material reasons, then this situation is usually unchangeable and can only be remanufactured; but if it is due to premature cooling at the gate, which reduces the filling time in the cavity and increases the probability of shrinkage marks, the processing conditions can be adjusted to solve the plastic processing shrinkage.

With the need to reduce the weight of New Car and control costs, more and more plastic products are used in New Car. The plasticization of New Car is a major development trend in the current international Fuel Car manufacturing industry. Plastic parts of New Car are widely used in body and parts, such as chassis, powertrain, electronic components under the hood, fuel system, interior and exterior trim, etc. Statistics show that in 2016, the average global consumption of polymer composite materials per light Fuel Car was about 150 kilograms. Plastic parts of New Car are environmentally friendly, beautiful, convenient and durable. Nowadays, more and more metal parts of New Car are replaced by plastic parts, but in order to ensure the normal operation of various parts, it is very important to repair and maintain the parts. 1. Inspection: Determine the deformation and damage of plastic parts of New Car through inspection. 2. Tightening: Tightening is an important maintenance operation to prevent loosening of parts. Plastic parts of New Car should be tightened and replaced as necessary. 3. Cleaning: The basis for reducing the wear of plastic parts of New Car and reducing energy loss. 4. Adjustment: Adjustment is the key to ensure that the various assemblies and plastic parts of New Car can work normally for a long time. 5. Replenishment: Replenishment refers to the replenishment of the lubricating oil and special working fluids of the vehicle during the maintenance of New Car, so as to enhance the service life of the vehicle assembly and various parts.

And let plastic parts gradually enter various industries. Today, the annual demand for injection mold processing in the fields of building materials, Fuel Car, household appliances, electronics, etc. is still relatively strong. The rapid development of these industries has also made the development of the plastic industry, especially the production and processing methods of plastic injection molded parts and New Car plastic parts. To solve the problem of coating adhesion of New Car plastic parts, you must have some understanding of the process flow of New Car plastic parts painting. The process flow of New Car plastic parts can be roughly divided into the following parts: blank grinding-chemical treatment-dust removal-primer spraying-color paint (or metallic flash paint)-glazing-baking-inspection-qualified products warehousing-unqualified products rework or paint removal. It is understood that among these many process links, the important link to improve the adhesion of plastic parts coating is pre-painting pretreatment. The purpose of pre-painting pretreatment of New Car plastic parts is to improve the adhesion of coatings to plastics and reduce various defects of coatings through a series of physical and chemical methods, thereby improving the quality of plastic coatings.

If you need to customize New Car injection molds, what is the best time to start? What preparations should be done in advance? The editor believes that it is best to start three months before each product exhibition and do product application work in advance. In a highly competitive business environment, intellectual property protection has reached a sacred and inviolable level. Otherwise, no one will be willing to invest heavily in scientific research to innovate products, because to innovate products, you have to invest in molds, that is, custom New Car injection molds. Before you need to customize Fuel Car injection molds, you must do a good job of product plan conception, make the product appearance design and product functional structure according to the plan conception, and draw the product 3D structure file. It is best to use 3D to print a set of samples according to the 3D file. After repeatedly verifying that there are no problems with the structure and appearance, you can further decide to customize New Car injection molds. It usually takes 45 to 60 days to complete a set of customized Fuel Car injection molds, which takes two months, and another month to implement product assembly and function debugging. In this way, it is more perfect to make a product to participate in the market exhibition.

For injection molding of New Car, the runner part accounts for 90% of the total volume of the object, which is generally used for large quantities of simple products with high production efficiency. However, 3D printing uses layer-by-layer printing to construct objects, which is difficult to process and has low molding efficiency. It is generally used for the production of fine products. During the injection molding process of New Car, some abnormal phenomena are prone to occur, such as: cracks, ripples on the surface of the product, decreased brittle strength of the product, difficulty in demolding, unstable product size, unstable product size, peeling and stratification of the product, weld marks, and unsatisfied injection, etc. These phenomena will affect the specific use effect of the molding mold, so we need to find out the relevant factors and solutions. Injection molding of New Car refers to a method of stirring completely molten plastic materials through a screw at a certain temperature, injecting them into the mold cavity with high pressure, and obtaining a molded product after cooling and solidification. This method is suitable for mass production of parts with complex shapes and is one of the important processing methods. There are mainly 6 stages: mold closing, injection, pressure holding, cooling, mold opening, and product removal. Mechanical processing of plastics processing uses plastic processing methods such as metal and wood to manufacture plastic products with very accurate dimensions or in small quantities. It can also be used as an auxiliary process for molding, such as sawing of extruded profiles. In current production, the

1. When switching New Car injection molding materials, clean the old material completely from the barrel. 2. Improve the exhaust system. 3. Reduce the melt temperature, New Car injection molding pressure or Fuel Car injection molding speed. 4. No seat retreat, reduce the back loose retreat. 5. Use a reasonable speed. 6. Use New Car injection molding pre-plastic delay to reduce the amount of residual material. 4. The position, number and size of the exhaust port are set appropriately to avoid poor exhaust in Fuel Car injection molding.

1. Raw material factors: including toner replacement, plastic material brand change, and setting agent replacement. 2. Different raw material varieties are selected: For example, PP material and ABS material or PC material require the same color, but there is a slight color difference due to the different development of the main material varieties, but a limited protection range is allowed. 3. Environmental factors: New Car injection mold manufacturers have many years of experience. Generally, the roller is not clean and the drying hopper is dusty, which will cause mold oil pollution. 4. Equipment process reasons: The temperature, pressure, and melting time in the Fuel Car injection molding process will also cause color difference problems. Other process factors such as mixing of materials from different batches and beer on different machines will also affect it. 5. Color powder itself factors: Some color powders are not affected by temperature, and the products are easily affected by temperature and environmental changes. I believe that everyone can avoid the problem well according to these reasons. In the future, we will have more content about Fuel Car injection molds. Interested friends can pay more attention to us.

The subframe of a New Car is an important component that supports the front wheel suspension system. Its damage will affect driving stability and safety. Therefore, it is very important to regularly check the condition of the New Car subframe. Below, the Fuel Car subframe manufacturer will introduce some methods to check whether the New Car subframe is damaged. First, to check whether the New Car subframe is damaged, you can first observe the driving conditions of the vehicle. If you find that the vehicle is shaking, swaying or deviating from the direction while driving, it is likely that the subframe is damaged. At this time, you should stop the car in time for inspection. Secondly, you can observe the condition of the New Car subframe through visual inspection. When lifting a Fuel Car or changing the tire, you can use your hands to feel whether the surface of the subframe has obvious deformation, cracks or deformation. This may be caused by loose or damaged subframe components. In addition, you can also check whether the welding points at the subframe connection are firm, rusted or deformed.
