As people expect a higher level of medical standards, the medical industry has used more high-performance engineering plastics in the past two decades, such as PEEK which can be implanted into the human body, and PI and PEI with very good performance.

PEEK

PEEK is definitely the most excellent engineering plastic in the medical industry in the 21st century. For medical products, PEEK is non-toxic and can still maintain the good mechanical and chemical properties of the material itself in corrosive solutions. PEEK materials are very suitable for precision machining. In our PlasticPartsCustom, the processing accuracy of PEEK can reach +/-0.01mm, which is very suitable for products with high accuracy requirements in the medical industry. In addition, PEEK parts have good strength and hardness, and toughness is also very good. Unless under very extreme working conditions, PEEK machined parts have a relatively long working life.

Because PEEK material is not toxic and can withstand more than 1,000 autoclave sterilization at temperatures as high as 130 degrees, in recent years, many products processed by PEEK have been sterilized and implanted in the human body for example Human bones, heat pumps, etc., PEEK CNC machined parts have made outstanding contributions to the human medical industry.

In addition, PEEK has recently been found to be an important component of shadowless lamps. We have successfully produced black PEEK machined products for medical shadowless lamps and exported them to South Asia, Europe, and the United States. Of course, in the early stage of materials selection, we also met some problems. For example, the parts processed by PEEK can only be partially penetrated by X-rays, and the penetration rate is relatively low, and can only reach about 60%-70%, which will cause some shadows when working. After repeating research by our engineers, we have confirmed the special properties of PEEK material suitable for the production of shadowless lamps, so as to make full preparations for the subsequent successful machining of PEEK accessories for shadowless lamps.

PEI

PEI is an amber translucent material. It is hard and tough. After precision machining, it can reach high precision. It is very suitable for making some high-end product parts. The insulation effect is relatively good. Many of the PEI machined products we produce are used as insulation blocks for medical and petroleum welding equipment. In the welding industry, PEI is usually matched with FR4 machined parts, which are used for welding parts of petroleum pipeline welding. Welding parts are often required to withstand high temperatures, when welding pipes, the temperature often rises with welding time, often reaching more than 200 degrees, or even close to 300 degrees, and PEI can be applied to welding because it can be as high as Long-term work at a temperature of 340 degrees. After 3 years of research and continuous trial, we-PlasticPartsCustom has accumulated rich experience. At present, we regularly supply CWS and SWS welding machine series to Swagelok after-sales service manufacturers, such as aluminum, FR4, PEI, Stainless steel, and other welding suits. For specific product details, you can find related products on our metal processing and non-metal processing related pages.

In the medical industry, medical-grade PEI products can withstand repeated washing and repeated steaming in a pressure cooker, and they can resist ultraviolet rays and Y rays. Because of its excellent characteristics, PEI’s machining and turning parts are widely used In medical equipment.

PI

PI is undoubtedly a noble in the engineering plastics industry. It has very good mechanical and chemical properties and is widely used in the medical industry. However, due to its high price, the scope of application is relatively narrow. For example, most PI CNC machined parts will be used in the medical industry and aerospace.
