Injection pressure injection pressure injection system is provided by a hydraulic system. Hydraulic cylinder pressure is transmitted to the plastic melt plastic injection supplier in Shenzhen, the 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 through the injection molding machine screw ), sprue, runner, and through the gate into the mold cavity plastic injection plant, the process is the plastic injection molding process, otherwise known as the filling process. For pressure to overcome the resistance during the melt flow, or conversely, the presence of resistance to flow 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, the pressure to flow along the length of the wave front at the forefront of the melt gradually reduced, if the cavity inside the exhaust is good, the forward end of the melt pressure is atmospheric. Many factors affect the melt filling pressure, summed up in three categories: (1) the material factors such as the type of plastic and viscosity; (2) structural factors such as the type of gating system, number and position of the mold cavity shape and thickness of the article; (3) molding process elements. Injection temperature injection molding temperature is an important factor affecting the injection pressure. Plastic Injection Molding Machine 5 to 6 heating section, each material has its appropriate processing temperature (processing temperature can be found in the detailed data material suppliers). Injection temperature must be controlled within a certain range. Temperature is too low, poor melt plastics, affecting the quality of molded parts, increasing the difficulty of the process; temperature is too high, the material is easy to break down. In the actual injection molding process, the injection temperature is often higher than the cylinder temperature, higher than the value of the injection rate and material properties related to plastic injection-stop, up to 30 ℃. This is because when the melt is subjected to shear Gate passage and generate high heat caused. In making mold flow analysis can be used to compensate for this difference in two ways, one is to try to measure the melt temperature when air injection, and the other one is modeling the nozzle also included.
