![]() ![]() Return material may be the main source of contamination, we recommend that you use special equipment and do its cleaning well to ensure that PEEK material is not contaminated by other materials during its operation. Before starting injection molding of PEEK, it is important to clean the screw and barrel properly and efficiently to ensure that the equipment is clean and free of other material residues. As you will learn, most other polymers degrade at the processing temperatures of PEEK, necessitating the use of a clean oven and feed system. ![]() The third point is an important requirement: keep it clean! Avoid any contamination when handling PEEK. A dehumidifier or hot air dryer can also be used and must be able to maintain a dew point or saturation temperature of -40☌. ![]() The aim is/should be to reduce the residual moisture content to <0.02%. In short, we recommend placing the pellets on the tray in a conventional oven and drying at 150-160☌ for 2-3 hours, optionally continuous drying. In our data sheet and injection molding guide, we provide some dry guidance. The second point pertains to dry PEEK polymers: PEEK pellets should generally be dry, but absorb moisture from the atmosphere. All metal parts should be smooth and highly polished to well avoid material degradation due to prolonged local residence in the barrel. Copper and copper alloy materials (in contact with the melt) should be avoided. Universal screw suitable for PEEK injection molding. In addition, the use of high-temperature-resistant insulation materials to insulate the barrel can also be considered, thereby saving energy costs. We recommend that you use a ceramic heating coil because of its higher heating consistency. If necessary, if a heating system modification is required, it is usually necessary to modify the heating coil or thermocouple/controller of the injection molding system. Most standard injection molding machines can reach these temperatures without retooling. PEEK grades, the processing temperature of the injection molding machine barrel will be between 350-400⁰C. The first is equipment for PEEK injection molding: PEEK can be molded on standard injection molding machines from most well-known machine suppliers. PEEK plastic makes an excellent reinforcement material, providing great tensile strength with low weight.Five factors to consider in PEEK injection moldingġ) Equipment: Standard injection molding machine PEEK resin holds up well against high temperatures and long-term liquid submersion and is very durable in harsh environments. PEEK plastic exhibits superb mechanical properties and is highly resistant to chemicals and thermal degradation, making it a highly desirable material for plastic injection molded products. Our range of machine sizes between 15 to 320 tons means we can mold PEEK molding parts ranging in size from 0.1 g. Our in-house peek injecction molding operation uses all electric machines with appropriately sized barrels minimizing time at temperature during PEEK molding to maximize the properties and consistency of every part we molded. ![]() Ming-Li offers PEEK injection molding of all Victrex PEEK, RTP PEEK, Luvocom PEEK and others PEEK material grades.
