High Precision ABS Injection Mould for AC Indoor Cover
Plastic Injection Molds for Air Conditioner Indoor Unit Housing
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
