Influence of injection mold on dimensional accuracy of injection products

In order to ensure the dimensional accuracy of injection molding products in the process of injection molding, it is necessary to choose a stable and reliable injection molding machine with sufficient pressure to produce, and the precision of the injection mold itself is also particularly important. So what is the influence of injection mold on the dimensional accuracy of injection products? The following will be detailed from several aspects.

1. Influence of injection mold structure and manufacturing accuracy on dimensional accuracy of injection molding products

The higher the manufacturing precision of the injection mold, the higher the precision of the finished product will be theoretically. Therefore, the manufacturing precision of the injection mold itself is very important. In order to achieve high precision manufacturing, we must choose the right material and high precision processing equipment. In addition, in the design of injection mold structure, not only to consider the parting surface of the mold, so that the molding and removal of plastic parts; Also consider the plastic parts in the injection mold processing when the flow of the melt.

2. Influence of injection mold wear on dimensional accuracy of injection molding products

On the one hand, the long-term work of the moving parts of the injection mold, such as the wear of the guide column guide sleeve leads to the accurate reduction of the mold to expand the size error of the injection product; On the other hand, because the mold cavity is in the high temperature and high pressure working environment for a long time and the injection molding raw materials or additives friction, the mold cavity will appear wear, thus affecting the dimensional accuracy of injection molding products.

3. Influence of injection mold rust on dimensional accuracy of injection molding products

The rust of injection mold will lead to the decline of the appearance quality of injection molding products, and will also affect the dimensional accuracy of injection molding products to a certain extent. Therefore, the maintenance of injection mold is also very important, and the rust of injection mold should be avoided.

4. Influence of high temperature resistance and high rigidity of injection mold on dimensional accuracy of injection products

If the injection mold can resist high temperature and the rigidity is high enough, there will be no mold deformation, so as not to affect the dimensional accuracy of injection products. If the high temperature resistance and rigidity is not high enough, on the contrary!

Injection molding products are released from the cavity of injection molding, injection mold structure and manufacturing accuracy will directly affect the dimensional accuracy of injection molding parts. The mission of Fanstar is to master the core technology of injection molding production, communicate and analyze the technology before mold production with customers from the production needs of finished products, so that the mold delivery time is short, the service life is long, the rapid mass production and the finished product quality is excellent!
