Injection pressure injection pressure injection system is provided by a hydraulic system. Hydraulic cylinder pressure is transmitted to the plastic melt by injection molding machine screw, plastic melt under the impetus of pressure, the injection molding machine nozzle into the mold of the vertical flow path (for the portion of the mold is also the main road), the main road, diversion Road and through the gate into the mold cavity, this procedure is the injection molding process, otherwise known as the filling process. For pressure to overcome the resistance of the melt flow during Baoan transparent plastic plants, or conversely, the flow resistance is present during the injection molding machine needs to offset the pressure to ensure the smooth progress of the filling process. In the injection molding process, the pressure at the nozzle of injection molding machines up to overcome the flow resistance throughout the melt. Thereafter transparent plastic, pressure along the length of the flow to the forefront of the wave at the front melt gradually reduced, if the cavity inside the exhaust is good, the forward end of the melt pressure is atmospheric. Factors affecting the melt filling pressure of many Shenzhen transparent plastic processors, summed up in three categories: (1) the material factors such as the type of plastic and viscosity; type (2) production of transparent plastic structural factors, such as the gating system, The number and position of the mold cavity shape and thickness of the article and the like; (3) forming a process element. After the process of shrinkage characteristics of plastic parts from the mold then cool to room temperature, the size of the contraction occurs this performance is called shrinkage. Due to shrinkage of the resin itself is not only thermal expansion and contraction, but also with the forming factors, the shrinkage after molding of plastic parts should be called molding shrinkage. Shenzhen transparent plastic processors _ integration into a plastic mold factory (certification) _ transparent plastic from Shenzhen harmony 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.
