According to statistics, in 2020, the global medical device industry scale has exceeded 480 billion U.S. dollars, and is expected to maintain about 5% growth in the next few years. As the upstream industry of medical devices, medical injection molding, driven by demand, is expected to usher in a round of development opportunities. Therefore, Yize Mould decided to enter the medical injection molding industry a few years ago. However, in the process of entering the medical injection molding industry, we encountered some technical difficulties.

1. Material selection

First of all, material selection. Medical devices often require higher purity of raw materials. This not only requires us to choose higher quality raw materials, but also requires us to pay more attention to the corrosion of the molds and processing equipment itself during processing, (see PFA chapter) and even need to change and optimize the previous injection molding process. With the efforts of our engineers, we finally overcame this technical difficulty. At present, we have been able to carry out injection molding of PC, PP, ABS, PEEK, LCP, PTFE, PVDF, PFA and other materials.

2. Dust free injection molding

There are many medical products that have dust-free injection molding requirements. Yize Mould has recently obtained the certification of Class 1000 clean room injection molding. The clean room can exclude particles, bacteria and other harmful substances in the air, and also has a stable temperature and humidity environment, which can not only eliminate the contamination of medical devices in the process of injection molding and production, but also provide a stable external environment for the production of medical devices, to ensure the stability of the quality of medical devices.

3. Precision requirements

Medical device injection molding often has high precision requirements, the tolerance often can not exceed 0.05mm or even 0.02mm, in order to achieve such high precision, we have been working hard. At present, we have reached the goal of controlling the tolerance of injection molded products within 0.02mm.

It can be seen that the medical injection molding industry has a broad prospect. And Yize Mould will continue to work hard to become a practitioner of the Chinese dream of manufacturing precision medical molds and related products.
