The materials used in mold manufacturing have a significant impact on the performance, lifespan, and cost of the mold. The following is a detailed introduction to commonly used mold manufacturing materials:

1. Cold working tool steel:

Cold working tool steel is commonly used to manufacture the core, cavity, and other parts of molds. It has high hardness and wear resistance, and is suitable for most plastic molds and die-casting molds.

2. Hot work tool steel:

Hot work tool steel is suitable for molds that require high-temperature working environments, such as injection molds and die-casting molds. It has good heat resistance and hardness.

3. Stainless steel:

Stainless steel is commonly used for mold components such as screws, nuts, etc. Has good corrosion resistance and is suitable for precision molds and food packaging molds.

4. Aluminum alloy:

Aluminum alloy is commonly used to manufacture lightweight molds, suitable for rapid prototyping and low-pressure casting. Has good thermal conductivity and processability.

5. Hard alloy:

Hard alloy (hard alloy steel) is commonly used as a cutting tool for manufacturing molds, such as cutting tools, blades, etc. High hardness and wear resistance.

6. Engineering plastics:

Engineering plastics, such as nylon, polyamide, etc., are commonly used to manufacture some components of molds. Has good wear resistance and impact resistance.

7. Ceramic materials:

In some special applications, ceramic materials can be used to manufacture high-temperature, high-strength molds, such as injection molding high-speed molds.

8. Magnetic materials:

Some electromagnetic molds require the use of magnetic materials to achieve magnetic field control. These materials are usually steel and nickel alloys.

9. Plastic:

For plastic injection molds, the mold itself may use some special wear-resistant and corrosion-resistant plastic materials.

10. Rubber:

The material used to manufacture rubber molds is usually vulcanized rubber or silicone rubber, which has good elasticity and wear resistance.

The selection of these materials depends on multiple factors such as the specific application of the mold, cost considerations, wear resistance, thermal conductivity, etc.

The continuous innovation and progress in material science in the field of mold manufacturing will provide more material choices and improvement space for mold manufacturing to meet the needs of different industries and fields.
