These points must be noted during mold processing.

During the production and processing of molds, they are generally formed in batches. Therefore, we pay great attention to the methods and processes of mold injection. If the processing does not follow the specified requirements, it may damage the injection mold.
1. Raw materials generally do not need to be dried, except in individual cases where they should be baked at 80℃ for 2 hours.
2. The molding temperature range is quite large, and the heating, melting, and curing speeds are fast, so the molding cycle is generally short; Temperature parameters: barrel temperature around 200℃, if the material temperature is too high, silver streaks may appear, while if the material temperature is too low, transparency will be poor.
3. Mold temperature control: The mold temperature is generally between 50-80℃.
4. GPPS has good fluidity, and high pressure is not needed during injection molding to avoid excessive internal stress in the plastic parts, which may lead to cracking.
5. The injection speed should be appropriately high to reduce water marks, but since the injection speed is greatly affected by injection pressure, excessively high speeds may lead to issues such as flash, sticking to the mold during demolding, and white marks or cracks during ejection.
