In the production process of medical injection molding products, molds play a crucial role, transforming design concepts into tangible objects. The processing of medical injection molds involves multiple complex steps. Today, we will focus on one of the key steps - polishing, and delve into the reasons and significance behind it.
After the processing of medical injection molds is completed, their surfaces often leave tool marks from CNC machining or spark textures from electrical discharge machining. These marks not only affect the appearance of the molds but may also impact the quality and finish of the final products. Therefore, the polishing step is particularly important. So, why do medical injection molds need to undergo manual polishing?

This primarily stems from two core purposes:

Firstly, to enhance the surface finish of the molds. Through polishing, the mold surfaces can become smoother and more delicate, thereby producing medical injection molding products with a more aesthetically pleasing appearance and better texture. This is undoubtedly crucial for medical products that pursue high quality and precision.

Secondly, to optimize the mold release effect and improve production efficiency. The surface roughness of the molds directly affects the ejection of the products. If the surface roughness is poor, the products are prone to sticking to the molds, which not only affects production efficiency but may also damage the molds. Therefore, reducing the surface roughness of the molds through polishing can effectively prevent product sticking and improve production efficiency.

Of course, in addition to manual polishing, mirror electrical discharge machines are also an effective means of improving the surface finish of molds. They are mainly used for precision machining of complex mold cavity surfaces and can shorten the production cycle. However, the processing cost of mirror electrical discharge machines is relatively high, and not all components are suitable for processing with them. In contrast, although manual polishing has a longer cycle time, the surface finish it can achieve for certain components is unmatched by mirror electrical discharge machines.

It is worth mentioning that manual polishing requires extremely high skill levels from operators. Each polishing technician needs to carefully and conscientiously complete every operation step, and each processing procedure needs to undergo strict inspection. It is this pursuit of extreme quality that has enabled companies like Dongguan Yize Mold to stand firm in the industry and win the trust and praise of many customers.
