Key Features of Aluminum Mold for Plastic Injection

Aluminum mold for plastic injection use aluminum alloy as the core material for the mold cavity. They offer advantages such as high processing efficiency, low cost, and rapid heat dissipation, making them suitable for small to medium batch production or prototype development. However, they are weaker than steel molds in terms of wear resistance and lifespan, requiring a trade-off based on specific needs. The following is a detailed analysis of their core characteristics:

1. High Processing Efficiency: Aluminum alloys have significantly better machinability than steel, with cutting time only 1/2 to 1/3 that of steel. Furthermore, EDM speeds are 3-4.5 times faster than steel, and wire EDM speeds are 2-2.5 times faster. This significantly shortens the mold manufacturing cycle, making it particularly suitable for rapid prototype development or small to medium batch production.

2. Cost Advantage: Although the unit price of aluminum alloy is higher than that of steel, its processing cycle is shortened by 40%, and the mold weight is reduced by 65%, resulting in a lower overall cost.

3. Excellent Heat Dissipation: Aluminum alloys have a high thermal conductivity (approximately 167 W/(mK)), allowing for rapid heat dissipation during the injection molding process, reducing cooling time and improving production efficiency.

4. Diverse surface treatments: Aluminum alloys support surface treatments such as hard anodizing and nickel plating, with a surface hardness of up to HV800 or higher, meeting the requirements for high gloss.
