If the gold 1!2 temperature is less than 50°C, the surface of the molded product tends to be roughened, and if it exceeds 250°C, it becomes difficult to solidify, so both are not preferred. If the injection holding pressure is less than about 10 kg/cd, filling of the resin in the mold tends to be incomplete, and if the injection holding pressure is extremely high, it will be difficult to suppress the occurrence of flash in the molded product. I also don't like it. If the injection cycle is extremely short, the assimilation of the resin within the mold tends to be insufficient, and if the injection cycle is extremely long, the polymer will remain in the injection machine for a long time, causing discoloration and deterioration of the polymer.
