Major game manufacturers recently learned, a major player in the gaming city usually are generally young people, but now in Japan, has become a lonely old people pass the time, to make the place of an old friend. Senior citizens affected by declining birthrate, the young Japanese gaming city less and less lonely old man has become the new major player in the gaming city. Perhaps after China, with more and more empty nesters, some gaming city in China, will also appear this situation. Therefore, businesses can have this opportunity to buy some security for the elderly to play simple video game consoles. 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. In theory, the shorter the filling time Gushu Japan qualified suppliers, 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 situation exists suppliers, 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, so the more obvious effect of heat conduction airport qualified suppliers in Japan, 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 Chung better qualified suppliers in Japan, can penetrate the wound each other, in addition to high temperature melt area two shares temperature relatively close to the thermal properties of the melt are almost the same, increases the strength of the weld zone; conversely at a low temperature region, poor weld strength.
