Generally, the photocuring forming speed is fast, the photosensitive resin material used has thermosetting property, and the manufacturing precision can reach 0.1 mm or more. Individualized PEEK parts are injection-moulded with metal moulds, which have the disadvantages of high processing cost, serious material waste, low efficiency and cumbersome processes. Traditional injection moulding is suitable for high-volume, standardized PEEK parts manufacturing. The edges of PEEK parts manufactured by FDM are easy to warp and deform, and the mechanical properties of PEEK parts are difficult to meet the requirements of using parts. The flexural properties and interlaminar shear strength of PEEK moulded parts made by fused deposition modelling (FDM) forming technology are poor. The traditional mould costs are high, the production cycle is long, and the PEEK material is wasted during the machining process. Injection moulding needs to be matched with the corresponding mould design and manufacturing. The traditional PEEK processing methods mainly include injection moulding, machining and the like. The advantage of additive manufacturing (AM) technology is that it can quickly manufacture parts with complex structures and individual structures and has high material utilization. It has been widely used in aerospace, automobile and other fields. It has good high-temperature resistance, fatigue resistance, high strength and corrosion resistance. Polyether ether ketone (PEEK) is an inert polymer material with excellent properties. The injection method in this study greatly reduced the production cost of individualized PEEK parts and can obtain PEEK parts with good mechanical properties in a relatively fast time. Photosensitive resin mould has lower cost, shorter production cycle and no waste of PEEK material during injection process. The experimental results show that it is feasible to produce photosensitive resin mould to inject individualized PEEK parts by stereolithography. The results showed that the average tensile strength was 96.4 ± 2.28 MPa, the average bending strength was 147.654 ± 9.36 MPa, and the impact strength was higher than 10 kJ/m 2. Mechanical tests were carried out on PEEK samples injected by this process. The optimum parameters of PEEK injection process were obtained by orthogonal experiment: injection temperature 373 ☌, injection pressure 11 MPa and injection speed 70%. In simulation experiment, the temperature field of the PEEK injection mould was analysed by finite element analysis it was preliminarily determined that the resin mould will not be deformed during the injection process. PEEK are the perfect choice for any high-tolerance, high-heat, chemical resistant plastic requirements.In this study, photosensitive resin mould was made by stereolithography technology to inject individualized polyether ether ketone (PEEK) parts. PEEK is often considered a superior high-end engineering plastic. In its solid state, PEEK is readily machinable by CNC milling machines and is commonly used to produce high-quality plastic parts that are thermostable and both electrically and thermally insulating. Hydrolysis resistant, even against super-heated steam.Įxtremely strong and wear resistant plastic. Mechanical stresses and demanding environmental conditions make it a premium engineering plastic of choice for many applications.Ĭreep resistant and excellent resistance to high energy radiation. This broad range of useful properties in addition its ability to retain them over a long period under elevated temperature PEEK carries a V-0 flammability rating and exhibits very low smoke and toxic gas emission when exposed to flameAlternative to fluoropolymers, these rods are applicable for manufacturing insulation materials, gears, bearings, bushes and valves.Poly Ether Ether Ketone known, as PEEK is a semi crystalline thermoplastic with high tensile strength, stiffness, good wear resistance, low coefficient of friction, excellent chemical resistance and very low moisture absorption. PEEK is a high strength alternative to fluoropolymers. (PEEK) offer enhanced tribological and other properties for demanding custom application. Virgin PEEK plastic rodPeek is commonly specified for high temperature applications requiring combination of thermal, chemical and combustion properties.
