The following issues should be considered when equipped with auxiliary equipment.
1) whether the raw materials are dry, should take technical measures.
2) offcut waste disposal methods, reuse methods and technical requirements.
3) Parison reheating device temperature control
4) Blow molding or injection mold temperature control.
5) Drying of compressed air and selection of pressure.
6) blow molding products after the cooling system
7) blow molding products surface treatment, surface printing method
8) blow molding quality (dimensions, pressure, anti-leakage, resistance to environmental pressure cracking, etc.) inspection methods, methods and tools.
