Barrel Temperature Of Injection Molded Parts

Melt temperature is very important, the use of the injection cylinder temperature is only guidance. The melt temperature can be measured at the nozzle or by air injection. The temperature setting of the injection cylinder depends on the melt temperature, screw speed, back pressure, the amount of injection material and the cycle of the molded part. If you do not have experience in processing a particular level of plastics, please start with the lowest setting. For ease of control, the injection cylinder is divided into areas, but not all are set to the same temperature. If the operating time is long or operating at high temperatures, set the temperature of the first zone to a lower value, which will prevent premature melting and diversion of the plastic. Make sure that the hydraulic oil, hopper sealer, mold, and injection cylinders are at the correct temperature before starting the molded part.
