Filling the filling phase is the first step in the process of injection molding cycle time from the beginning of the injection mold closing date, the mold cavity is filled to about 95% so far. Theoretically, the filling time is shorter, the higher the molding efficiency, but in practice, the injection molding time or speed is restricted by many conditions. High-speed filling. When the high-speed filling shear rate, due to the plastic shear-thinning and viscosity decrease of the presence of the case of precision machining game handle, so that the overall flow resistance is reduced; local influence also makes viscous heating cured layer thinner. Therefore, flow control stage, filling behavior often depends on the size of the volume to be filled. That flow control stage, due to the rapid filling game processing, shear-thinning effect of the melt tend to be large, and the cooling effect is not obvious thin, so the rate of utility prevailed. Low filled. Low thermal conduction control mold filling game processing, low shear rate, relatively high local viscosity, flow resistance is large. Thermal plastic replenishment rate is slow, slow flow, the heat conduction effect is significant, the heat quickly taken away for the cold mold wall. Plus smaller amounts of viscous heating phenomenon, cured layer thicker, and further increase the flow resistance at thin wall portion. Because of the fountain flows, the flow of the wave front in the plastic polymer chain is almost parallel to the front row of the flow of the wave. Therefore, the two share a plastic melt at the intersection, the contact surface of the polymer chains parallel to each other; plus two shares in the melt different nature (different residence time, temperature and pressure are different in the cavity), resulting melt intersection region poor micro structural strength. In the light of the part put the proper angle with the naked eye, you can find a clear generation bonding wire, which is the formation mechanism of weld marks. Welding marks not only affects the appearance of plastic parts, and because of the loose microstructure, could easily lead to stress concentration, so that the strength of the lower portion and fracture. Generally, in the high-temperature region produces welding weld line strength is better, because the situation at a high temperature, the polymer chain mobility is better, can penetrate the wound each other, in addition to two shares of the melt temperature is high temperature region is closer to the melt thermal properties almost identical five game processing, increasing the strength of the fusion zone; the other hand in a low temperature region, the weld strength is poor. Wholeheartedly committed to integration into a plastic mold production and processing Japanese video game industry, favored by many Japanese manufacturers. All kinds of game consoles plants, integration into a plastic mold factory (certification), game integration process 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.
