Parameter/Guideline
Drying
100-110°C / 4-6 hours (Absolutely Critical, must use a dehumidifying dryer)
Melt Temperature
190 - 210 °C (Mid-to-low range recommended to avoid thermal yellowing)
Mold Temperature
20 - 40 °C (High-gloss polished molds are recommended for optimal clarity)
Equipment Cleanliness
The machine must be thoroughly purged with transparent-grade ABS or PC before production to eliminate any contamination.
Critical Precautions
1. Cleanliness & Drying are Paramount: Any trace of moisture, dust, or foreign material residue will cause haze, bubbles, yellowing, or splay marks, completely ruining transparency.
2. Avoid Thermal Degradation: Strictly control melt temperature and residence time. Overheating instantly causes yellowing and permanent loss of clarity.Purge Suggestion
Must use high-transparency grade ABS or PC as purge material. Purge for an extended period at low speed and at the lower end of the processing temperature range until the purged strands run completely clear. Never use PP, PE, or recycled material for purging.
