What materials are used for plastic mold lifters?

Plastic molds are key tools for producing various plastic products. The molds are composed of different materials and components, and an important part of them is the lifter (also called lift pin). The lifter is a conical structure that allows the parts in the mold to be demolded smoothly during injection molding.

Specifically, after the injection molding machine injects the molten plastic, it waits for the plastic to cool and solidify, and the rubber head must maintain a small gap with the cavity wall because it needs to support the plastic part. In this process, how to design the lifter is critical.

The following are 5 commonly used materials for plastic mold lifters:

1. Cr12Mov steel material
Cr12Mov is a high-quality high-carbon alloy steel with very high hardness and strength, and can withstand high temperatures and long-term use. Its characteristics are excellent corrosion resistance, high impact strength, good processing performance, good wear resistance, etc. Cr12Mov lifters are usually suitable for manufacturing large molds because these molds need to withstand huge pressures.

2. 45# steel material
45# steel is a low-carbon steel material widely used in the manufacture of small and medium-sized injection molds. It has good machinability and toughness, and is relatively cheap. However, the hardness of this material is low, and it is only suitable for some smaller molds that do not need to withstand high pressure.

3. SKD11 steel material
SKD11 steel is a cold-working tool steel that is widely used in the manufacture of injection molds because of its toughness and wear resistance. Its main characteristics are good rigidity, strong corrosion resistance, and good castability. The steel can resist loss under high temperature and high pressure, which makes it very useful in the manufacture of large injection molded products.

4. H13 steel material
H13 steel is considered to be one of the high-quality mold steels. Its main characteristics are high thermal stability, balanced hardness and toughness, excellent wear resistance and heat resistance, etc. H13 steel is widely used in various types of plastic molds due to its superior performance, especially for the manufacture of molds with long service life and high frequency of use.

5. S136 steel material
S136 steel is a high-quality stainless steel with the characteristics of high strength, good wear resistance, high precision, strong corrosion resistance, etc. S136 steel is usually used to manufacture high-precision parts in injection molded products, such as electronic equipment, medical equipment and mechanical accessories.

In short, as an important part of plastic molds, the selection of materials for the inclined top is one of the key factors affecting the production quality and service life of plastic molds. Choosing the right inclined top material can improve the durability and production efficiency of the mold and bring more economic benefits to the manufacturer. Of course, how to choose excellent materials needs to take into account the specific production environment, production scale, product requirements and other factors for comprehensive consideration.
