A new cutting method - PTFE laser cutting technology

Polytetrafluoroethylene membrane, referred to as EPTFE, is a polymer polymer that is a valuable material for various harsh environments due to its resistance to liquid penetration, biocompatibility and low dielectric constant. EPTFE products can provide good performance and reliability, from medical devices implanted in the human body, to clothing worn on Mount Everest expeditions, to cables that transmit signals in outer space, meeting customer expectations and end-user needs. Therefore, it is popular in all walks of life.

When used for filtration and separation, it usually exists as a membrane, that is, PTFE membrane as mobile phone handsets, electronic housings, power plants, disk drive filters, pharmaceutical and chemical processing, pulp and paper, metal processing and chlor-alkali. However, how is PTFE cut during the production process? Today, the editor will show you the following points. Common PTFE exists in membranes or sealants, gaskets, clothing fabrics, etc. Traditional cutting methods are usually grinding wheel cutters, blade cutters, etc. Today, the editor introduces a new cutting method-PTFE laser cutting technology.

The laser cutting machine adopts a non-contact cutting method and has no stress on the material surface. The cutting accuracy is higher than that of knife cutting and grinding wheel cutting, with high cutting efficiency and smooth and flat edges. It is suitable for various special-shaped cutting. The cutting accuracy of PTFE film can reach 0.02mm, which is particularly suitable for industries with high precision requirements such as the electronics industry, medical industry, aerospace industry, etc.
