Focused on home appliance injection molding, this article analyzes common defects of transparent parts and provides full-process solutions in material, mold, process and equipment to improve yield and product quality.
In the field of home appliance injection molding, transparent parts (AC panels, refrigerator drawers, washing machine windows, water purifier housings) require extremely high transparency, defect-free surface, low internal stress and high strength. Defects such as bubbles, sliver marks, weld lines, whitening and cracking directly affect appearance and qualification rate.
Material: Virgin transparent grade, fully dried, dust-free
Mold: High polish, strong venting, balanced cooling, large draft
Process: Medium-high barrel temp, high mold temp, stable injection, sufficient holding
Machine: Good plasticizing, no dead corners, precise response
Heat-treatment: Anneal high-stress parts
For transparent parts in home appliance injection molding, the core is to control stress, maintain cleanliness, optimize flow and stabilize cooling. Through four-dimensional optimization of material, mold, process and equipment, defect rate can be greatly reduced and yield improved, creating higher-quality transparent home appliance parts.
