Automotive lamp molds are typically made from materials that can withstand high temperatures, pressure, and repeated use. The specific choice of material depends on factors such as the complexity of the mold design, production volume, cost considerations, and the specific requirements of the automotive lamp being manufactured. It's worth noting that advancements in materials and manufacturing techniques may introduce new options or variations in the materials used for automotive lamp molds.

The most common materials used for automotive lamp molds include:

Steel: Steel is a widely used material for automotive molds due to its excellent durability and heat resistance. It can withstand the high temperatures involved in the injection molding process and maintain its shape over extended periods.

Aluminum: Aluminum molds are also popular choices for automotive lamp molds. Aluminum offers good thermal conductivity, allowing for faster cooling during the molding process. It is lighter than steel, which can make handling and maintenance easier.

Copper alloys: Copper alloys, such as beryllium copper, are used in some specialized automotive lamp molds. These alloys have excellent thermal conductivity and can provide efficient cooling, resulting in faster production cycles.

Tool steels: Various tool steels, such as H13 and P20, are commonly used for automotive lamp molds. These steels are specifically designed for mold-making applications and offer a balance of hardness, toughness, and heat resistance.
