Qingdao High-Tech Mold Co., Ltd., a manufacturer of high-end automotive injection molds, shares its experience using AMPCOLOY® 83, 940, and 944 in complex mold core cooling applications.

In automotive injection molds, uniform heat dissipation and rapid cooling are critical to maintaining dimensional stability and reducing cycle times. In narrow cavities and thin-walled sections where cooling channels are difficult to machine, material thermal conductivity becomes a determining factor.

High-Tech Mold applies AMPCOLOY® high-conductivity copper alloys in complex mold areas such as speaker grille regions of door panels and dashboard visor components. The company reports:

• Faster heat transfer in narrow cavity zones
• More uniform mold wall temperature distribution
• Reduced cooling time compared to steel molds
• Production cycle improvements reported between 20–40% in cooling phases

The alloys’ high thermal conductivity enables more stable temperature control, helping to reduce deformation, warpage, and shrinkage in complex plastic components.

Beyond material performance, High-Tech Mold highlights long-term collaboration, consistent quality, and technical support throughout implementation.
