Plastic Injection Mold Manufacturer

Plastic Injection Mold Manufacturer

1, Core and cavity have three-dimensional surface.

Plastic products external and internal shapes are depend on core and cavity and it is very difficult to process this complex three-dimensional surface, especially the process of blind hole. If we use traditional process, it not only requires high technical level of work,but also need long period of processing .

2,High accuracy and surface quality requirement, long service time.

Presently, the plastic products size accuracy requirement is about IT6-7, surface roughness is Ra0.2-0.1μm, while injection mould fitting size accuracy requirement should be achieve to IT5-6 and surface roughness lower than Ra0.1μm. Plastic injection molds long-life for is essential improving efficiency and reducing costs

If you want to improve efficiency and reduce cost, I think you need a long life injection mould. Currently, the general useful time of injection mould is more than 100 million.Precision injection molds need a big stiffness mould frame, heavy template, and many support column or cone positioning device in order to prevent the deformation of the mold. The ejection equipment will affect the products’ deform and size accuracy, so we should choose the best ejection point, then guarantee the even demould.

For the structural design, most of high accuracy injection moulds choose mosaics structure; it will improve the processing accuracy and the interchange ability of mould part.

3, Long process, tight manufacture time.

A complete product always consists of injection product and part components supporting. Because of high requirement for products shape or size accuracy and because there are many characteristics of resin material, so after finishing the mould’s manufacture, we should test and modify the mould repeatedly, reducing developing and delivery time.

4, Remote design and off-site manufacture

Mould manufacture is not the finally destination, mould manufacture’s destination is appeal to customer’s requirement. Ordinarily, customer brings forward finally design, according to the customer’s requirement, mould manufacturer start to produce.

5, Specialize division, dynamic combination

Generally, mould production is always single, but there are many standard elements, such as mould frame and ejection pin. These can’t be finished in one manufacturing process.
