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
