What are the Advantages of machining PEEK? It is typically classified as either industrial-grade or medical-grade. The high-performance PEEK plastic is available in granular form, in filament for 3D printing, and in bar / rod form for CNC machining. But with a melting point of 343☌, PEEK can operate at higher temperatures: it can be used continuously to 250☌ and in hot water or steam without permanent loss in physical properties. PEEK grades offer chemical and water resistance similar to PPS. The semi-crystalline material is used for a wide range of industrial parts and components, exhibiting excellent strength, wear resistance, and abrasion resistance, and retaining its properties even at high temperatures. PEEK, or polyether ether ketone, is a high-performance engineering thermoplastic and part of the PAEK family of materials. This article goes over the fundamentals of machining PEEK: the material properties of PEEK, the advantages of machining PEEK, common applications of machining PEEK, and tips for how to get the most out of machined PEEK parts. Despite being regularly used for injection molding and 3D printing, PEEK has a high melting point, which would indicate its suitability for subtractive processes like CNC machining - although PEEK machining comes with its own set of challenges. The plastic has excellent mechanical properties and a high level of resistance to corrosive substances, making it highly desirable for manufacturers across the world. PEEK is a popular thermoplastic polymer found in objects as diverse as medical implants and electrical cable insulation. PEEK machining, PEEK 3D printing, or PEEK injection molding? Without the use of any additives, the flammability rating of the 1.45mm thick PEEK sample is UL94 V-0.6. When immersed in steam at a temperature exceeding 250☌ or in high-pressure water, PEEK products can still work continuously for thousands of hours without significant performance degradation.Ĩ: Flame retardancy. It can perform post-processing such as turning, milling, drilling, tapping, bonding and ultrasonic welding.ħ: Resistance to hydrolysis. The parts can be directly processed by injection molding process. It also has high rigidity and surface hardness.Ħ: Easy to process. It has the best mechanical strength among plastics. It is insoluble in common solvents and has good corrosion resistance to various organic and inorganic chemical reagents.ĥ: High intensity. It can achieve oil-free lubrication, and can work for a long time in oil, water, steam, weak acid and alkali and other media.Ĥ: Corrosion resistance. PEEK polymer and its composite materials have excellent wear resistance in many extremely harsh application environments such as high temperature, high load, and strong corrosion.ģ: Self-lubricating. Even when the temperature is as high as 300 ℃, it can still maintain excellent mechanical properties.Ģ: Wear resistance. The long-term use temperature of American UL certification is 260℃. More PEEK machined parts for your reference.ġ: High temperature resistance. PEEK machined parts can be widely used in medical and health care,petrochemical engineering, electronic and electrical,, machinery and automobiles,, aerospace, military, nuclear energy and instrumentationģ. Shipment : by DHL/FEDEX if need urgent, also can by road or by sea if want to save transport cost. MOQ: prototype and mass production are acceptable. We used PEEK material which comply with FDA regulation 21 CFR 177.2415 for repeated food.ĭelivery time: 3-5 days for prototype, 7-10 days for mass production. The PEEK material is available in the below colors: natural color and black. However, Lemo team has rich experience and advanced 4 axis and 5 axis CNC machining to process them. Requires special handling to minimize internal stress and heat-related cracks during machining. PEEK machined parts are very difficult to process due to this is special plasic material, it It exhibits excellent strength, wear resistance, and abrasion resistance, and retains its properties at high temperatures. PEEK, or polyetheretherketone, is a popular thermoplastic used for a wide range of industrial parts and components. The typical PEEK parts we made for USA and European customer are : Rollers and wheels,Peek Bearings ,Peek O-rings, Peek Washer,Peek Seats, Peek Bushings, Peek Guide Blocks, Peek Wear Pads. Lemo Precision Metal has 19 year's experience for processing PEEK machined parts by CNC machining,CNC milling or CNC turning.
