Ways to improve the service life of injection molds


In the age of industrial development, injection mold is the most critical root in injection mold factory, and it is also an indispensable important process. The quality of its processing is not only related to the excellent performance of plastic products, but also to the company’s Production machining costs have a very direct relationship. Therefore, in order to further improve the efficiency of the use of PTJ molds and reduce the cost of plastic products, let’s talk about how to improve the service life of injection molds.

1. Application of plastic raw materials

Different plastic types require different temperatures during molding, and the shrinkage rate of plastics is also different. Therefore, different working conditions have different effects on the service life of the mold. Therefore, on the premise of satisfying the performance and product quality, generally, plastic raw materials with good process performance should be selected to process the finished product, which is conducive to the molding of the product and the improvement of the mold life.

2. Mold structure design

Cavities and cores are the main molding parts of molded plastic parts. Whether the strength and rigidity of the cavities of different structures and the convenience of repair and replacement of vulnerable parts are different. Therefore, from the perspective of the service life of the mold, the use of a structure that has better strength and rigidity and is easy to repair can extend the life of the mold.

3. Mould material and heat treatment

Injection molding models are generally more complex, with high accuracy and surface roughness requirements. The selection of mold materials will affect mold quality and use quality

4. Mold use and maintenance

The correct use and maintenance of the mold is also a major factor that affects the service life of the mold. The mold is adjusted according to the appropriate method, and the mold is produced in accordance with the parameter design requirements of the injection molding machine. Measures such as planned and regular maintenance of the mold can be Improve the service life of the mold to a certain extent.
