Sprue sets are usually made of high carbon tool steel. Injection mold sprue design elements are as follows: 1. To facilitate gating system condensate material pulled from the main road in and consider expansion of the plastic melt, acrylic, sprue design into a cone. 2. The big end of the main channel was rounded with a radius take r = 1 ~ 3mm, in order to reduce the flow rate of the steering transition resistance. 3. ensure the plastic forming under good conditions, the length of the injection mold sprue should be as short as possible, otherwise it will increase condensate material sprue, acrylic products plastic mold, and increase the pressure loss, acrylic products manufacturers, the plastic melt Injection molding cooling too much. 4. molten plastic completely into the main channel without overflow, should be the main channel of the injection machine nozzle close docking, the production of acrylic products, plastic goods, docking at the main channel designed into hemispherical pits. Sprue parts are frequently designed to be disassembled sprue bushing to high quality steel processing and heat treatment alone, so the use of electric heating in the main channel of the material in order to raise the temperature. Injection molding cycle time by a mold, filling time, dwell time, cooling time and the release time components. Among them, the largest proportion of the cooling time, about 70% to 80%. Accordingly, the cooling time will directly affect the plastic molding cycle length and the volume of production. Stage plastics release temperature should be cooled to below the heat distortion temperature of the plastic products, to prevent warping due to the slack of plastic products due to residual stress or external forces caused by the release and deformation.
