"220V Cooling Fan" plastic injection molding complex shapes can be formed at one time, the precise size or plastic inserts. In the injection mold design. We must be fully aware of the following three features:
(1) plastic melt are mostly fake plastic liquid, shear thinning. It depends on the variety of materials flow, shear rate, temperature and pressure. Therefore, the rheological characteristics shall gating system design and verification cavity pressure and clamping force.
(2) depending on the "220V Cooling Fan" injection mold cavity pressure to withstand high pressure container. It should be based on correct estimation of the mold cavity pressure on the structural design of the mold. To ensure the mechanics of the mold is closed, molding, mold, mold release and reliable core-pulling, the mold parts and plastic parts of the stiffness and strength, etc. must be fully taken into account.
(3) "220V Cooling Fan" throughout the molding cycle, plastic parts - mold - Environment formed a dynamic thermal equilibrium systems. The heat transfer theory of plastic parts and mold design applied to the mold temperature control system to ensure product quality and the best economic indicators.
