In the custom processing of injection molds, the precise positioning of workpieces is a crucial aspect of ensuring product quality and production efficiency.

Gas marks are a common and troublesome issue in injection molding. They manifest as tree-like, wave-shaped scratches on the surface of plastic parts, centered around the gate, significantly affecting the product's aesthetics and quality.

So how does Yize Mould choose the right mold processing method? ① Firstly, after receiving a customer order, Yize Mould will synthesize the experience and risk of each position in the risk assessment meeting in the pre-design phase of the mold to ensure the smoothness of the precision mold design, processing and mass production;

By asking customers about the material of the product and requesting product drawings, Yize Mould better understands the customer's needs and determines the degree of precision of the medical mold, so as to save the customer's cost.

This PFA Wafer Cassette is custom molded and injection molded by Yize Mould according to customers' needs. As a preferred container for semiconductor wafers/silicon wafers, it maintains excellent performance in harsh environments by virtue of its resistance to acids, alkalis, and corrosion (including strong acids, hydrofluoric acid, and strong bases). In addition, it still operates stably even at a high temperature of 260°C (500℉) , demonstrating strong heat resistance.

We reached a strategic partnership with a silicone injection molding company. Since we have the hard plastic precision injection molding capabilities that this company desperately needs, this company can complement us in our product making capabilities. In addition, we have strengthened our supply chain management in order to better communicate and cooperate with our upstream and downstream companies.In addition, we have strengthened our product design capabilities because customers often need…

With the development of science and technology, the demand for small precision parts is getting higher and higher, and the application of micro injection molding will become more and more widespread. Therefore, for us, overcoming the technical difficulties of micro injection molding is not only to complete the user's order, but also to promote the overall development of the industry forward, and it is also a solid step for us in the field of medical injection molding.

Performance comparison of PTFE, FEP, PVDF, PFA and ETFE

In the previous article, we introduced you to the properties of FEP and its comparison with PTFE. In this issue, we will introduce the main application fields of FEP: electronic and electrical industry, 5G communication, chemical industry, and medical industry.

FEP, known as polyperfluoroethylene propylene, commonly known as F46, FEP is a copolymer of tetrafluoroethylene (TFE) and hexafluoropropylene (HFP), a copolymer of tetrafluoroethylene and hexafluoropropylene, with the content of hexafluoropropylene of about 18% or so, FEP is the modified material of polytetrafluoroethylene (PTFE).

In 2022, as PVDF becomes more and more important in emerging applications, the proportion of PVDF consumed in the traditional coating field is decreasing to only 30%. In the same year, the proportion of PVDF consumed by lithium batteries rose to 39% from 8% in 2017; and the proportion of PVDF consumed by photovoltaic backsheet membranes rose from 3% to 6%. This all shows that the PVDF industry is undergoing great changes, and we believe that in the future, PVDF can also shine in more applicati…

In the previous article we introduced two kinds of plastics, PFA and PTFE, and gave a detailed account of the properties and uses of these two kinds of plastics, and today we will introduce the second most used fluoroplastic: PVDF.
