What is the difference between injection mold and plastic mold?

The difference between injection molds and plastic molds is mainly reflected in the following four aspects:

1. Concept:
Injection mold is a kind of mold by injecting plastic raw materials into the mold, forming under high temperature and pressure, and then obtaining the required plastic products. This mold is usually used for mass production and can produce a large number of plastic products in a short time.

Plastic mold refers to the products that have been processed and formed, which are products processed by using plastic raw materials through various mold processing methods. Such molds are usually used to produce single or small amounts of plastic products, or to repair or reproduce certain plastic products.

2. Materials:
The materials of injection molds are mainly metal materials such as steel and aluminum alloy, because these materials have high strength and durability, and can withstand the impact and wear of plastic raw materials under high temperature and pressure.

The material of plastic mold is mainly the plastic raw material itself, because these materials have the characteristics of low cost and easy processing, and can manufacture a single or small number of plastic products in a short time.

3. Manufacturing process:
The manufacturing process of injection mold usually includes design, processing, assembly and debugging. This mold needs to be carefully designed and manufactured to ensure that plastic raw materials can be accurately formed under high temperature and pressure, and the required plastic products can be obtained.

The manufacturing process of plastic molds is relatively simple, and usually only requires simple processing and assembly. This mold needs to take into account the characteristics of the plastic raw materials and the requirements of the processing process to ensure that the plastic products that meet the requirements can be manufactured.

4. Application field:
Injection molds are mainly used in mass production fields, such as home appliances, automobiles, electronics and other industries. Because injection molds can quickly produce a large number of plastic products, these industries need a large number of injection molds to meet market demand.

Plastic molds are mainly used in small-scale production fields, such as handicrafts, toys, medical equipment and other industries. Because plastic molds can quickly produce a single or small number of plastic products, these industries need fewer plastic molds to meet market demand. In addition, plastic molds are also used to repair or copy certain plastic products, such as auto parts, medical equipment and so on.

In summary, although injection molds and plastic molds are related to plastics, they have obvious differences in concept, materials, manufacturing processes and application fields. In practical applications, it is very important to choose the right mold manufacturing method according to different needs and materials.
