plastic injection for Pet product In the process of filling the mold cavity of TPE products, if the filling performance of the product is not good, the pressure drop will be too large, the filling time will be long, and the filling will be unsatisfactory, which will cause the product to have quality problems. Let me share with you some things that need to be paid attention to in the TPE molding process. TPE injection molding The matters needing attention in the TPE molding process are as follows: Coloring: The color masterbatch carrier should be compatible with the selected TPE material. For SBS-based TPE, PS or EVA-based colors are more appropriate, while SEBS-based TPEs use PE or PP-based colors. The color is more suitable, the color with EVA as the base has poor thermal stability, and the color with PVC as the base cannot be used for TPE. In order to make the dispersion process easier, the color masterbatch should have a lower viscosity than the basic TPE composite material ( higher melt flow index). For many overmolding materials, the use of a polyethylene (PE) carrier may adversely affect adhesion, and if the wax content in the color masterbatch is high, adhesion may also be reduced. Shrinkage rate: The shrinkage rate of TPE material depends on the formula. In the range of 0.5-2%, the shrinkage rate of the melt flowing into the mold in the reverse direction will be higher. Generally speaking, the shrinkage rate of SBS is smaller, while that of SEBS is smaller. The shrinkage rate of materials with higher density will be slightly larger than that of materials with lower density. In addition, processing conditions such as mold temperature, melt temperature, injection speed and product thickness will affect the product shrinkage rate. Drying: TPE generally does not have hygroscopicity and does not need to be dried. However, excessive moisture in the secondary injection molding material or matrix will have an adverse effect on the adhesion. For varieties that need to be dried, the moisture content is required to be 0.1. %the following. Cooling time: The required cooling time depends on the melt temperature, the wall thickness of the workpiece and the melt index of the material. Harder varieties set faster than softer varieties and are easier to demould. Due to the poor thermal conductivity of the plastic matrix, the TPE can only be cooled from one side, so the overmolded workpiece needs a longer time to cool. The cooling time required for an overmolded workpiece is typically 20-40 seconds per 0.100" of overmolded layer thickness.
Plastic Friut Basket Mold Recommendations for mold steel materials: 1. In general, if the amount is large, we strongly recommend that the mold base is made of 45# steel, and the core, cavity and slide block are made of 718H nitriding. Such a mold can be made at least 1 million times. 2. If the mold base with a small amount is made of 45# steel, and the core, cavity and slider are nitrided with P20, the product produced can be produced with 500,000 molds. 3. In the amount of less than 200,000, all ordinary steel heating treatment can also be done. Mold after-sales problems: 1. 100% guarantee the normal production of customers 2. 100% after-sales service 3. 100% real materials
Plastic Auto Rubber Mud Guard Mould The mudguard is a plate structure installed behind the outer frame of the wheel. It is usually made of high-quality rubber material, but also engineering plastics. The mudguard is usually installed on a metal baffle behind the wheel of a bicycle or motor vehicle, a cowhide baffle, a plastic baffle, and a rubber baffle. The effect after installation is that the mudguard is about 5cm protruding from the body. This 5cm effectively prevents flying stones and gravel from damaging the paint surface of the body. Processing technology: The specific processing technology of the fixed core is: material preparation (the material is P20, pre-hardened) rough milling six sides grinding benchmarks punching and tapping CNC rough machining CNC finishing (precision is used at the peripheral corners of the fixed core Engraving) â??Fine milling benchmark diagonal â??Deburring â??Rough polishing â??Fine polishing. Absorb the lessons of the past, before the fixed mold core is subjected to CNC finishing, the workpiece should be subjected to stress relief treatment to prevent deformation and cracking of the workpiece. The specific processing technology of the movable core is: material preparation (the material is P20, pre-hardened) rough milling six sides grinding benchmarks drilling and tapping â?? CNC rough machining CNC finishing EDM wire cutting Finish milling reference diagonal deburring rough polishing fine polishing. The specific process of the core is: material preparation (the material is P20, pre-hardened) rough turning grinding reference and finishing turning fine milling (with mold). The processing technology of other parts can be carried out according to the conventional technology.

Mold maintenance is mainly divided into three points: 1. Daily maintenance of the mold, various moving parts such as thimbles, row positions, guide posts, guide bushing, cleaning of the mold surface, and dredging of water. This is the daily maintenance of mold production . 2. Regular maintenance. Regular maintenance includes cleaning the exhaust trough in addition to long-term maintenance, trapped gas burned at black level and exhaust, and correction of damage and wear parts. 3, appearance maintenance, the outside of the mold is painted with paint to avoid rust. When lowering the mold, the fixed mold of the moving mold should be coated with anti-rust oil. The mold should be closed tightly when stored to prevent dust from entering the cavity.
Plastic Injection Food Box Mould The basic structure of the plastic lunch box mold: Plastic parts are produced by injection molding. Therefore, the designed mold must have higher injection molding. The product is designed for mass production efficiency, and the pouring system must be able to automatically demould, and the point gate automatic demoulding structure can be adopted. Because the shape of the plastic part is relatively simple and the quality is small, mass production is required. The gate type adopts point gate feeding, so that the mold size is small, the manufacturing and processing are convenient, and it is conducive to filling the cavity, the quality of the plastic part is high, and the production efficiency is high. , The cost of plastic parts is low. Points for Attention in Mold Manufacturing: Need to choose the appropriate product specifications and shapes: the current shapes on the market include round and rectangular shapes, and the conventional capacities are 500ml, 750ml, and 1000ml. The rounded products are slightly lighter than the square ones. Mold material selection: Because the product wall thickness of thin-walled molds is only 0.4-0.8mm, the mold needs to withstand high pressure, so thin-walled molds need high-hardness steel materials to prevent mold deformation under long-term high-speed and high-pressure, resulting in flashing of the product , Increase costs and other issues. Mold design: product parting surface, product wall thickness design, mold exhaust design, mold waterway design, mold blowing position and direction design, these issues directly determine the success or failure of a thin-walled mold.
Features of PP plastic faucet PP is a semi-crystalline material. It is harder than PE and has a higher melting point. Since the homopolymer PP is brittle at temperatures above 0 �° C, many commercially available PP materials are random copolymers with an ethylene content of 1-4% or block copolymers with a high ethylene content. Copolymer PP material has low heat distortion temperature (100C), low transparency, low gloss and low stiffness, but higher impact strength. The strength of PP increases with increasing ethylene content. The Vicat softening temperature of PP is 150 �° C. Due to the high degree of crystallinity, this material has very good surface rigidity and scratch resistance. PP does not have the problem of environmental stress cracking. Generally, PP is modified by adding glass fiber, metal additives or thermoplastic rubber. PP flow MFR range is 1 ~ 40. PP materials with low MFR have better impact resistance, but lower strength. For the same MFR material, the copolymer type has higher strength than the homopolymer type. Due to crystallization, the shrinkage of PP is very high, usually 1.8% to 2.5%. The uniformity of shrinkage direction is much better than PE-HD and other materials. Adding 30% glass additives can reduce the shrinkage to 0.7%. Homopolymer and copolymer PP materials have excellent resistance to moisture absorption, acid and alkali corrosion resistance and resistance to dissolution. However, it cannot resist aromatic hydrocarbons, such as benzene solvents, chlorinated hydrocarbon (carbon tetrachloride) solvents, etc. Use of PP faucet: high quality and low price, non-toxic and tasteless, environmental protection, waterproof, product appearance, quality, sanitary, waterproof, durable, practical, environmentally friendly
Plastic fan blade mold Plastic leaf: light in weight and power saving, but it will deform after long-term use. It feels windless and will deform soon after correction. Plastic blades appear more in the family environment, the price is more affordable than aluminum blades, the motor load is small, and the noise is relatively small. In addition, because of the convenient processing, the design of plastic can be more flexible and diverse, not only serving as a cooling tool, but also playing a certain decorative role. Plastic blades are more convenient for cleaning and maintenance than aluminum blades. However, the plastic blade will be deformed and the wind force will be insufficient after long-term use.
1. Because the BMC material contains a large amount of glass fiber and filler, it will block the gap between the workpiece and the exhaust groove during molding. Exhaust is equal to discharge, and the exhaust vent should be easy to clean. The place that cannot be cleaned should be designed to take into account the parting surface structure and the cold trough. 2.The resin and filler will block the gap between the workpieces during molding. It is difficult to disassemble after long-term use and cooling. In addition to the thermal expansion of the metal and the accuracy of the product, the matching gap between the workpieces should be fully considered during processing. 3.Because BMC material contains high glass fiber, the flow is poor, the hardness of the material itself is high, and the mold is very worn. When designing, different materials should be considered, and the quenching hardness of the mold material (vacuum heat treatment) HRC50 or above), tempering temperature and surface treatment have high requirements (the mold core is recommended to use Japan's Datong H13 or Sweden 8407) to effectively ensure the use of the mold. 4.The open cavity distribution pattern should be reasonable: the balance of each cavity in a mold is crucial because it is the direct killer of the pass rate. It also affects the appearance of the product. When the balance is not good, the B mode has a problem when the A cavity is satisfied. Conversely, when the B mode satisfies the A mode, the process is difficult to satisfy. 5.BMC materials are very sensitive to temperature. When the temperature difference is large, the product will be deformed, cracked and oversized. Therefore, the mold should be more temperature-detected, and the temperature balance should be fully considered when designing the heating rod. 6.The design of the runner should be as low-pressure and low-speed as possible. The position and angle of the runner should avoid the direct impact on the easily deformable workpiece and the effective discharge of the gas inside the cavity.
Gas-assisted injection molding technology features (1) The design of the mold cavity should ensure the flow balance to reduce the uneven penetration of the gas, and ensure the flow balance is also a design principle of the common injection molding mold, but this is more important for the gas-assisted injection molding products. (2) The mold design should consider the influence on the process parameters, because gas-assisted injection molding is much more sensitive to process parameters than ordinary molding. In injection molding, small differences in mold wall temperature or injection volume can lead to asymmetry of gas penetration in symmetrical parts. Gas-assisted injection molding equipment (1) Ordinary injection molding machine (the metering accuracy is slightly higher). (2) Nitrogen control system, including self-sealing gas-assisted nozzles. (3) High pressure nitrogen generator. (4) Industrial nitrogen cylinders and air compressors that provide supercharged power. (5) A mold designed and manufactured for gas-assisted injection. (6) Gas-assisted injection molding gas auxiliary nozzle The nozzle air intake mode uses a special self-closing gas-assisted nozzle. After the plastic injection is finished, the high-pressure gas directly enters the plastic inside by the nozzle, and forms an extended closed space-air cavity according to the air passage and maintains a certain pressure until the pressure is maintained. Cooling, before the mold is opened, the nozzle is forced to separate from the product channel by the backrest of the table, and the gas is discharged from the product. (7) gas needle The air needle intake method is to install an exhaust deviceâ??a gas needle at a specific position of the mold. When the plastic is injected into the cavity, the gas needle is wrapped inside the plastic; at this time, the high-pressure gas is discharged, and the gas needle forms an extended closed space-air cavity according to the air passage inside the plastic, and maintains a certain pressure until cooling, and the mold is opened. Previously, the gas in the air chamber was discharged from the interior of the plastic by the control device by means of a gas needle.
