Plastic mold manufacturer What are the precautions for structural design
However, the protective film is relatively good after use. The main reason for its development is that the protective film is protected and shows unnecessary shrinkage. The same PE protective film is used in the manufacturing process. The temperature difference in the environment, the effect of use and the bonding process are designed to avoid unnecessary stretching. The construction of module library is mainly composed of two parts. The construction module library consists of three stages: module classification, structural feature model and user-defined feature creation. The standard part of plastic mold is a special case of the module existing in the module library. yes. Definition only requires two steps, while module partitioning is a modular design step.
1. Mix silica gel and curing agent evenly. The appearance of the molded silica gel is liquid, component A is silica gel, and component B is curing agent. Example: Take 100g of silica gel and add 2g of hardener, which will affect the life of the silica gel mold and the times of mold turnover, and may discard the mold.
Plastic Mold Structure Co., Ltd. has a variety of tools, which can make people more convenient in modern life. In order to beautify plastic products, it is usually necessary to polish the plastic mold before mass production. Otherwise, plastic products and product launches are very troublesome. The surface is also shiny. For example: notebook computer, charger, fan, etc. Therefore, attention should be paid to some details when polishing the plastic mold, otherwise the service life of the mold will be shortened.
In Plastic Mold Structure Co., Ltd., the non flow injection molding method refers to the adiabatic heating method using convection channels, and there is no injection system when the mold is taken out by keeping the plastic melt between the nozzle cavities of the injection molding machine. Material Science. The former is called adiabatic euro injection mold, and the latter is called hot runner injection mold.
Pre adjust a certain metering amount to apply additional injection pressure (second or third injection pressure) according to the filling conditions of the mold, so that a small amount of melt (buffer amount) remains on the screw tip near the end of the injection stroke. Add a little solution. In this way, the pressure of the product can be prevented or the shrinkage of the product can be adjusted.
Advantages of plastic mold system compared with other molds: plastic mold injection products have higher density, dimension temperature and mechanical strength than ordinary injection products, and the electrical performance can reach the level of die products. After the molding material is plasticized in the barrel, the cavity is filled by screw injection. The second stage is the compression molding stage, in which the parting surface is tightly combined under a certain pressure, and then the pressure is maintained and cured. After forming, open the mold and take out the product. The structure of plastic mold is actually very complex, but its advantages cannot be ignored.
