What is precision injection mold?

Precision injection mold is a mold used to manufacture high-precision and high-quality plastic products in the production of plastic products. Compared with ordinary injection molds, precision injection molds have more stringent requirements in design, manufacturing and processing to meet the needs of small size, tolerance, complex shape, assembly, insertion, and waterproof of products.

Precision injection mold features

1. High precision requirements
Precision injection molds need to reach micron level manufacturing tolerances, mold parts in the processing to reach micron level tolerances, in order to control the tolerance of injection plastic products between 0.01mm-0.05mm. And in the mold design and processing process, it is necessary to consider the shrinkage rate of the material, processing accuracy and assembly accuracy.

2. Complex structure
In order to meet the needs of complex products, precision molds often have complex cavity structures and multiple release mechanisms. This requires precision machining and clever structural design.

3. High quality materials
Precision molds usually use high-quality die steel, such as NAK80, H13, S136, SKD51 and so on. These materials have good wear resistance, polishing and heat treatment properties, which can ensure the service life of the mold and the quality of the product.

4. Precision machining technology
In the manufacture of precision molds, CNC machining, precision grinding machine machining, electric discharge machining, slow wire machining and other advanced processing technology are widely used to achieve the required accuracy and surface quality.
