Plastic Injection Molds for Air Conditioner Indoor Unit Housing
1. Product Process Description
The air conditioner indoor unit housing mold is manufactured using plastic injection molding technology. The mold cavity is precisely machined with CNC equipment, and
engineering plastics such as ABS, HIPS, or modified PP are melted
at high temperature and injected into the mold cavity. After
cooling and demolding, the final housing product is obtained.
Process workflow:
Mold Design & CAE Analysis → Optimize flow channels, cooling system, and structural strength
Mold Steel Selection & Processing → Use high-hardness steels (H13, S136) to ensure long service life
Injection Molding → Control temperature, pressure, and cooling cycle to ensure
dimensional accuracy and surface quality
Post-Treatment → Includes trimming, painting, silk-screen printing, UV coating,
etc. to enhance appearance and durability
