What is the difference between injection mold and stamping mold?

Injection mold and stamping mold are two different mold manufacturing methods, and there are some obvious differences between them.

1. Material and shape

Injection mold: mainly used in the manufacture of plastic products. Plastic raw materials are injected into the mold by an injection molding machine, formed under high temperature and pressure, and then the required plastic products are obtained.

Stamping die: mainly used in the manufacture of metal products. The sheet metal is placed in a mold, stamped under the action of a press, and then the desired metal product is obtained.

2. Design and manufacturing

Injection mold: The design should consider the characteristics of the plastic material, the parameters of the injection machine and the molding conditions. The manufacturing process involves complex structures, such as cavity, pouring system, etc., and the technical requirements are high.

Stamping die: The design should consider the characteristics of the metal material, the parameters of the press and the forming conditions and other factors. In the manufacturing process, stamping, cutting, bending and other processing operations are required, which is relatively simple compared with injection molds.

3. Application field

Injection mold: mainly used in the manufacture of plastic products, such as home appliances, automobiles, electronics and other fields.

Stamping die: mainly used in the manufacture of metal products, such as automobiles, aerospace, machinery and other fields.

4. Manufacturing cycle and cost

Injection mold: Long manufacturing cycle, high cost. It is necessary to take into account the characteristics of plastic materials, parameters of the injection machine and other factors, and the structure of the mold is also more complex.

Stamping die: Shorter manufacturing cycle and lower cost. Only a simple stamping operation is required, and the structure of the mold is relatively simple.

5. Development trend

With the continuous progress of technology and the advancement of industry 4.0, mold manufacturing has gradually developed in the direction of digitalization and intelligence. The technical content requirements for injection moulds and stamping moulds are also increasing. At the same time, with the enhancement of environmental awareness, green manufacturing and sustainable development have also become an important development direction of the mold industry.

In summary, there are obvious differences between injection moulds and stamping moulds in materials and shapes, design and manufacturing, application fields, manufacturing cycles and costs, and development trends. In practical applications, it is very important to choose the right mold manufacturing method according to different needs and materials.
