With the development of science and the continuous research of engineering plastic products, many excellent properties of engineering plastics are in line with the requirements of precision parts in the medical field, and many plastic machined products also meet FDA standards and USP VI standards, which guarantees Such products are widely and safely used in the medical field.

1. PMMA, also known as Acrylic, transparent plexiglass, is one of a large number of engineering plastics used in medical treatment. Due to the very high light transmittance of PMMA, currently in PlasticPartsCustom, For most PMMA machined products, we mainly use imported German EVONIK acrylic, which is basically free of impurities, has high toughness, and the light transmittance can even reach 92%-95% or more. In addition, for our machined domestic acrylic. The light rate can also reach about 90%, and it has good toughness. There will be no chipping or embrittlement during the CNC processing. It can also ensure good transparency in the long-term use.
   The high permeability of PMMA machined parts makes it a good medical container, such as blood culture dishes, body fluid storage tanks, etc. Most of the acrylic surface is atomized after machining, turning or milling. After half a year of research by our PMMA Engineering Department, we have basically solved the problem of surface fogging on acrylic machining through the improvement of tools and the improvement of programming. At present, most of the PMMA products we produce have smooth and translucent surfaces, and the holes in the products basically do not need to be polished, the threaded holes are clearly visible.
2. ABS resin
   ABS is a material that is particularly suitable for machining. This material is relatively hard, but at the same time, it has a certain degree of toughness. It is often used in medical devices. At present, most of the ABS raw materials are white or milky white, and ABS is a relatively economical material. , The price after customized CNC processing according to the drawings is relatively favorable, and it can be used as a consumable part of medical equipment.
   At PlasticPartsCustom, ABS is a common machined engineering plastic. Every year we export more than 30,000 pcs parts to the medical industry.
3. PA nylon
   Nylon material is well known to everyone. It is economical and affordable, and its strength and toughness are very good. In medical equipment, it is usually applied to many nylon machined parts. Nylon is a relatively good machined material, but because of its own good toughness and adhesion, the treatment after CNC machining will be a bit more troublesome. Most nylon products will have burrs on the surface after four-axis or five-axis CNC processing. Professional post-processing engineers are required to clean them, In our company The engineers have 3-5 years of experience, so we can clean the residual burrs on the surface and inner holes of the nylon parts under the premise of ensuring the product size.
4. PC
   Compared with PMMA (Acrylic), the transparency of PC is slightly worse, but good quality PC materials can also achieve a light transmittance of more than 75%, but the machined products of PC have obvious advantages. Its toughness is very good and it is not easy Cracking or chipping during CNC machining, turning, or milling, and its working temperature range is very wide, it can resist the low temperature of minus 50 degrees, can work for a long time under the high temperature of 120 degrees, and the short-term working temperature can reach about 200 degrees.
5. POM (Delrin)
   As one of the most cost-effective engineering plastics, POM has a very wide range of applications in medical equipment. In some machinery, it has partially replaced aluminum. After machining, POM can be well assembled on medical equipment. The stainless steel braces assembled inside the POM can make up for the insufficient hardness of the material itself when Assembly screws. At present, the surface of the POM machined parts is relatively easy to scratch, so pay more attention to the clamping during CNC processing and the subsequent processing and packaging after CNC processing.
