The main process parameters of injection molded parts include:

1. Barrel temperature: The melt temperature is very important. The temperature of the shot cylinder used is only a guide. Melt temperature can be measured at the nozzle or using air jet method. The temperature setting of the shot cylinder depends on the melt temperature, screw speed, back pressure, shot volume and injection cycle. If you have no experience processing a particular grade of plastic, start with the lowest settings. In order to facilitate the control, the injection cylinder is divided into zones, but not all are set to the same temperature. If operating for a long time or operating at high temperatures, set the temperature in the first zone to a lower value, which will prevent premature melting and divergence of the plastic. Before injection molding begins, make sure that the hydraulic oil, hopper seal, mold, and shot cylinder are at the correct temperature.
