The greening of New Car injection molding parts is a scientific strategy to achieve sustainable development. It mainly refers to the technical system that can protect and improve the ecological environment, reduce pollution and reduce energy consumption throughout the life cycle of the product. Based on the environmental value and the full potential of modern science and technology, there is no unified definition and evaluation standard so far. Its technical connotation mainly includes: ecological health, environmental protection, and maximum resource utilization. The greening of New Car injection molding parts is a system engineering of the whole set of solutions. The research and development of New Car plastic parts in my country is backward, and basically high-end plastic parts cannot be developed independently. An important aspect of the reason is that in the research and development of New Car plastic parts, domestic research institutions such as materials, product development, processing and manufacturing, molding equipment, and waste recycling are independent and do not interact with each other, and there is no concept of a complete solution. Plastic is the raw material of choice for lightweighting Fuel Car. The research and development of plastic raw materials for New Car injection molding parts must comply with green technologies that are non-toxic, harmless, healthy, and circular economy.

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.

The injection molding of New Car is developed with the development of synthetic resins, and it promotes each other with plastic machinery. Plastic parts processing is a general term for the various processes of converting synthetic resins or plastics into plastic products. Its process generally includes plastic batching, molding, machining, joining, modification and assembly. Here are some effects of wall thickness on product quality? The wall thickness of the product has a great influence on the quality. If the wall thickness is too small, the flow resistance is large, and large and complex plastic parts are not easy to fill the cavity. The smaller size of the wall thickness should meet the requirements of the following aspects: 1. It has sufficient strength and rigidity. 2. It can withstand the impact and vibration of the demolding mechanism during demolding. 3. It can withstand the tightening force during assembly. Too large wall thickness not only wastes raw materials, but also increases the molding time for Fuel Car injection molding, and is prone to incomplete curing. For thermoplastics, it increases the cooling time. In addition, it will affect the quality of its processing. The wall thickness of the same product should be as uniform as possible, otherwise additional stress will be generated due to uneven cooling and solidification speed. It is very important to determine the wall thickness reasonably. It is first determined by the use requirements of the plastic parts: including the strength, quality cost, electrical performance, dimensional stability and assembly requirements of the parts.

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.

The color of New Car injection molding parts is different from the single standard color sample when viewed with the naked eye, which is judged as color difference, under standard light source (D65); overflow (flash, flash): a thin layer of (flash) rubber appears along the parting line around the New Car injection molding parts or on the mold sealing surface, which is called overflow; size mismatch: during the molding process of New Car injection molding parts, the failure to maintain the original predetermined dimensional accuracy is called size mismatch. Depression: The surface of Fuel Car injection molding is uneven, smooth, and has shallow pits or dents inward; White top/high top: The surface of Fuel Car injection molding is obviously white or higher than the original plane; White spots: There are white particles in Fuel Car injection molding, which are also called "fish eyes" and are mostly reflected on transparent products; Insufficient strength (brittle cracking): The strength of Fuel Car injection molding is lower than expected, so that the plastic parts cannot withstand the predetermined load; Tiger skin pattern often appears on Fuel Car injection moldings with large areas such as bumpers, dashboards, door panels and pillars. It is a surface defect with wavy stripes. The stripes are approximately perpendicular to the melt flow direction, forming different gloss marks on the surface of Fuel Car injection moldings, which looks like the pattern on tiger skin, commonly known as tiger skin pattern. Tiger stripes are easily produced on New Car injection molded parts with thin walls and large flow rates. They have the following characteristics: (1) Periodic alternating light and dark stripes

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

Temperature is an important part of injection molding, and stable temperature is also the key to molding quality. The more important temperatures related to injection molding are: barrel temperature, New Car mold temperature, feed port temperature, and oil temperature. 1. Barrel temperature Generally, it is the temperature at which the resin is melted by heating with power. From solid to molten state, the temperature rise of plastic mainly comes from the barrel temperature and the shear heat given by the screw rotation. Theoretically, the ratio of their energy supply is 3:7. In the barrel temperature setting, different temperatures are set according to different raw materials. Among them, the temperature of the front end (nozzle area) should be slightly lower than the middle end to prevent runny nose; the rear end (feed area) should also be lower than the middle end, and 20-30 degrees lower than the front end, mainly to prevent abnormal feeding, and another is that the exhaust will be better, and the product is not easy to have silver wire and other defects. In addition, the molding temperature of any flame retardant (i.e. fireproof material) added should be 20-30 degrees lower than that of ordinary materials. The specific use temperature depends on the production situation, because the molding temperature directly affects the fluidity, viscosity, Fuel Car mold temperature, color, shrinkage, product deformation, etc. of the plastic. 2. Control of Fuel Car mold temperature The Fuel Car mold temperature is mainly determined by the fluidity of different plastics. Simply put, it is the key process to overcome poor fluidity. For example, the fluidity of PC

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 definition of New Car injection molding is that after the mold injection molding machine heats the plastic to a certain temperature, it injects the dissolved plastic into the closed mold cavity with extremely high pressure, and then the mold is cooled and shaped, and the plastic product is ejected by the top plate after the mold is opened. The elements of New Car injection molding are composed of four parts: plastic mold, injection molding machine, ordinary plastic, and molding conditions. The structure of the plastic mold is basically composed of two-plate molds, a small part uses three-plate molds, and the sliding mold with a slider is also included. The injection molding machine is mainly composed of plasticization, mold clamping device, injection device, and transmission mechanism. The motor in the injection molding machine is driven by electricity, and the motor drives the oil pump inside. The oil pump generates oil pressure, the oil pressure drives the piston, and the piston drives the entire machine to move. Conventional plastic materials can be divided into two types: thermoplastic and thermosetting. Thermosetting plastics usually refer to plastics that cannot be recycled and reused after injection molding, and their structure can no longer be processed. Thermoplastic refers to reusable plastics, which can be divided into crystalline and non-crystalline. The molding conditions of Fuel Car injection molding can be divided into six types, namely speed, pressure, temperature, time, stroke, and quantity. These six are very important during molding, and each part is indispensable.

Nowadays, the continuous improvement of production and processing technology has also made the quality of plastic products better and better. Everyone knows that plastic products are commonly used products in our lives, and our lives cannot do without the use of these products. Speaking of processing technology, New Car injection molding is a widely used process in the field of plastics. However, New Car injection molding also has influencing conditions. The following editor will tell you about this content. New Car injection molding is now widely used in our lives, so let's understand its influencing conditions. In the process of New Car injection molding, due to the volume change caused by crystallization, the pressure of New Car injection molding is high, the viscosity difference of molten material is small, the shear stress between layers is small, and the elastic rebound after demolding is large. Therefore, the shrinkage of Fuel Car injection molding can also be reduced appropriately. The material temperature is high and the shrinkage is large during New Car injection molding, but its directionality is small. Pressure During New Car injection molding, the molten material is greatly affected by shear, especially PE and POM are more sensitive, so the pressure during Fuel Car injection molding should be adjusted during molding to control fluidity. During molding, the material temperature, mold temperature, pressure, injection speed and other factors can also be controlled to properly adjust the filling situation to meet the molding needs. I believe that with the continuous development of society, the development of plastic products in our country will get better and better, so the re
