Injection molded products are mushy

The content of moisture and volatile matter in the raw materials is too high. The melt index of the raw materials is too large, and too much lubricant is used. The raw materials require high temperatures to be plasticized, such as PBT, PPS, etc.

In terms of molding operation, the injection speed is too high, the temperature of the melt is high, and the injection pressure is high.
