![]() The machinability of a material is influenced by its physical characteristics. ![]() high-quality thermal and electrical insulating capabilitiesĬonsiderations for Choosing CNC Machining Plastics.The bulk density of Teflon is exceptionally high. It doesn’t spark easily and doesn’t encourage the spread of flames. Teflon, which is a polymer of tetrafluoroethylene (PTFE), has exceptional dielectric qualities that are stable with frequency and temperature. It is frequently used for items that need an anti-stick surface because of its low coefficient of friction, making it an excellent choice for situations where components would move against one another. It is resistant to almost all industrial chemicals and solvents, withstands extremely high temperatures, and is a superb insulator. Teflon is a trademark of the American chemical corporation Chemours, a division of the industry titan DuPont (now DowDuPont). Tetrafluoroethylene (TFE) is a fluoropolymer and thermoplastic. ![]() Typically, it is either medical-grade or industrial-grade. PEEK is a high-performance plastic that may be found in granule, filament, and bar or rod forms for CNC machining. It can also be utilized in hot water or steam. PEEK, on the other hand, has a melting point of 343☌ and can withstand temperatures up to 250☌ without permanently losing its physical qualities. ![]() PEEK grades are comparable to PPS in terms of chemical and water resistance. The semi-crystalline material, which has outstanding strength, wear resistance, and abrasion resistance, and maintains its qualities even at high temperatures, is utilized for a variety of industrial parts and components. The PAEK family of materials includes the high-performance engineering thermoplastic known as PEEK, or polyether ether ketone. Superior density, reduced moisture absorption, and chemical resistance to hydrocarbons, solvents, and neutral chemicals are only a few of the qualities of the Delrin substance. There are many grades of Delrin that each have a unique combination of characteristics.ĭue to its high tensile strength, low friction and high wear resistance, creep and warp resistance, and general toughness and longevity, Delrin plastic serves as a great alternative to metal. The substance, which is also referred to as POM (Polyoxymethylene) or Delrin plastic, may be further machined using procedures like injection molding and 3D printing. In terms of producing plastic components, CNC machining is more accurate than injection molding.Īdditionally, compared to many other manufacturing techniques, CNC machining is more compatible with a wider variety of plastics, which makes it an attractive option for many product teams to produce parts through machining.Īn acetal polymer known by the trade name Delrin is widely utilized in CNC machining because of its remarkable characteristics. PEEK, PEEK G元0, PEEK FC30, PEEK CA30 and PEEK MG.Plastics are essential to the current manufacturing sector because they are generally accessible, most of them are inexpensive, and they work with well-liked production techniques like injection molding, 3D printing, and CNC precision milling.ĬNC machining is a subtractive manufacturing technique that involves carefully removing material from a solid block of material with spinning tools and drills to shape the component. We stock PEEK plastic in extruded round bars, extruded sheets/plates and tubular bars. It is not resistant to sulphuric acid, nitric acid, halogens, or MEK at raised temperatures. PEEK has good resistance to water and water vapour (un-filled material has excellent hydrolysis resistance), alcohols, esters, alkaline solutions, oils, fats and fuels. We supply full machining instructions on request. As with all plastic materials, experience has shown that extra care must be taken with larger diameters, especially in the colder months when plastic materials lose some of their toughness, and so have less resistance to machining stresses. The glass or carbon fibre reinforced grades will require tipped tooling. The machinability of un-modified PEEK is excellent. Perfect for components requiring tight manufacturing tolerances.Ability to operate in the most demanding applications and performance conditions.Superior all-round product for various applications.Examples include plain bearings, coil bodies, guide & clutch parts, gears, cams, rollers, slide bearings, seal rings and guide rails, pulleys & conveyors. PEEK finds use in mechanical engineering, automotive and general machinery construction. ![]() Known under the chemical name polyetheretherketone, PEEK is a quality, high-performing engineering plastic suitable for a broad range of engineering applications. ![]()
