Injection temperature injection molding temperature is an important factor affecting the injection pressure. Plastic Injection Molding Machine 5 to 6 heating section, each material has its appropriate processing temperature (processing temperature can be found in the detailed data material suppliers). Injection temperature must be controlled within a certain range. Low temperature plastic suppliers, melt plastics bad, affect the quality of molded parts, increasing the difficulty of the process; temperature is too high, the material is easy to break down. In the actual injection molding process, the injection molding temperature is often higher than the cylinder temperature, the higher the value of the injection rate and properties of the material concerned, up to 30 ℃. This is because when the melt is subjected to shear Gate passage and generate high heat caused. In making mold flow analysis can be used to compensate for this difference in two ways, one is to try to measure the melt temperature when air injection, and the other one is modeling the nozzle also included. Inch. 3, the factors affecting the shrinkage rate of change not only in the actual formation of different varieties of plastic shrinkage rates vary plastic mold factory suppliers, and different parts of the different batches of the same species in the same plastic or plastic parts of the shrinkage values ??are often different suppliers The main factors affecting changes in shrinkage following aspects. (1) plastic varieties kinds of plastic has its own range of contraction, the same type of plastic packing due to the different molecular weight and proportion and so on, it shrinkage and anisotropy are also different. (2) The characteristics of plastic parts plastic shape, size, wall thickness, with or without inserts Baoan quality plastic Suppliers, insert the number and size distribution of the shrinkage has a great influence. (3) sub-surface structure of the mold and die pressing direction, form, layout and size of the gating system and directional effect on shrinkage is large, especially in the extrusion and injection molding is more obvious. (4) forming process extrusion, injection molding process is generally larger shrinkage clear direction. Preheating, molding temperature, molding pressure, holding time, fill and harden in the form of loading has on the uniformity and directional shrinkage. Processing providers, integration into a plastic mold factory (certification), supplier integration by the Shenzhen Municipal Technology Limited. Shenzhen harmony Technology Limited (www.rhctech.net) Guangdong Shenzhen, plastic products leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. The integration into a plastic mold factory leadership with the staff warmly welcome all inquiries negotiations to create harmony into a plastic mold manufacturers a better future.
