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, 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 high-speed filling, melt shear thinning effect is often large, and the cooling effect of the thin-walled is not obvious, then the rate of utility prevailed. Low filled. Low thermal conduction control filling, 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 microscopic structure of loose gamepad, 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 almost the same thermal properties, increasing the strength of the fusion zone; the other hand in a low temperature region, the weld strength is poor. Video games are one of the four major French cultural industry, it is also a mainstay of the French high-tech products market. Second half of 2008 that swept the global financial and economic crisis suppressed technology products market in France for 10 years of growth. However gamepad processing which side is good, French video game industry successfully weathered the impact of the crisis, mainly due to the video game industry sustained rapid development in recent years Japanese gamepad processors, consumer groups and market scale of consumption continues to grow and expand, while Thanks to the French government in the "digital economy" policy framework, giving support policies and video game software development industry. Video games (jeux vidéo gamepad plants, also known as "video games") industry is the French "cultural industries Economy (Economie des industries culturelles)" an important part, in accordance with French industry classification definitions, cultural industries, including, of all industrial produced in the form of cultural products industries. Cultural products include books, audio and video, film, television, radio, video games and other traditional media and multimedia products. According to statistics, in spite of the outbreak of the global financial and economic crisis in the second half of 2008, but in 2008, sales of video games and related products France is still as high as 3.04 billion euros, an increase of 15 percent, the highest level. The video game industry and film screenings industry, TV industry, DVD optical disc industry have been tied for the French four cultural industries.
