First, identify materials and designs:

The most important part of the injection mold is the material, then what kind of material is good? Of course, the hard disk is high, corrosion resistance, and good polishing performance, long-term use of the mold quality is good. The overall design of the mold, including ejector and core; door design, parting surface, exhaust port, gate size and locations are reasonable, and then see whether the injection mold is open and close, product size is qualified.

Then you can see the mold technology:

To distinguish the quality of plastic mold technology, we first need to see whether the size of injection products is qualified. Secondly, the appearance of injection parts should be clean, and the joint surface, slider and core should not be burr. If all of these can be done, then the mold is a qualified mold.

Finally, the quality of mold products is distinguished.

1. stability and consistency of product size, surface finish and material utilization.

2. Service life: On the premise of ensuring product quality, the number of working cycles or the number of parts produced by the mold can be completed. 3. Whether the use and maintenance of the mold is the most convenient, demoulding is easy, auxiliary production time is as short as possible; Continuous maintenance costs, maintenance cycle, etc.

Knowing the following determinants, we can think of ways to improve the quality of the mold. The basic method of mold design is the most important step to improve the quality of the mold. More carefully.
