Several key aspects need to be considered during the injection molding process to ensure product quality and production efficiency.
Mold Design and Maintenance: The mold is the core of injection molding production. Its design must be reasonable to avoid defects such as burrs and shrinkage. The mold material should be wear-resistant and high-temperature resistant (such as 304 stainless steel), and regular maintenance and cleaning should be performed to extend its service life.
Material Selection and Drying: The appropriate type of plastic raw material (such as ABS, PP, PC, etc.) should be selected according to product requirements. The raw material must be fully dried before use to avoid bubbles or silver streaks on the product surface due to moisture. The drying temperature and time need to be adjusted according to the material characteristics, typically 80-120℃ for 2-4 hours.
Cooling System: The cooling method (air cooling/water cooling) must be selected according to the mold structure and production requirements. Uneven cooling may lead to product deformation or stress concentration.
Vacuum Control: For products requiring high precision, the vacuum control range (10-1000Pa) must be stable to avoid air bubbles or voids.
Safe Operation: The equipment must be equipped with overload protection, overpressure protection, and emergency stop functions. Operators must be trained and certified to avoid equipment damage or personal injury due to misoperation.
Product Inspection: During production, product dimensions, appearance, and performance must be sampled and inspected regularly, and process parameters adjusted promptly.
Environmental Control: The production environment should be kept clean to prevent dust or impurities from contaminating the raw materials or molds.
