1/19/2024 0 Comments Peek plastic with coolantSpecially developed for critical applications, it can be equipped with single or double mechanical seal (Type Someflu, Cartex or other).Īrticle relayed by : The Online Pump Magazine impeller. All the parts of the pump in contact with the fluid are made of thick resin in PEEK: volute casing, impeller with an over molded insert, cover, shaft sleeve, and cartridge. The prototype developed by Someflu is a pump of the NP series, size 80-50-200, a chemical process pump according to the ISO 2858 norm. These characteristics allow it to be one of the best-known engineering plastics and one of the most used in the technical industries. – Excellent chemical resistance to solvents, acids, bases – High temperature resistance (Over 200☌) We offer peek cnc turning and also provide. PEEK (PolyEtherEtherKétone) resin is a semi-crystalline material with a unique combination of mechanical, thermal and chemical properties: PEEK is a high-performance thermoplastic material that offers excellent mechanical, thermal, and chemical properties. It is now with the PEEK composite that Someflu extends its range. Subsequently, Someflu has developed many pumps for specific customers applications through the use of polymer resins such as PSU, ECTFE, or PVDF with carbon fiber reinforcement (CFRP). At that time, Someflu already offered pumps made of PFA-EL, PVDF-EL, PP-EL, PE-EL. In the past already, for the implementation of the ATEX Directive, Someflu was one of the first pump manufacturer to use antistatic conductive polymer resins to conform all of its product line while maintaining thick parts construction for all its pumps. In collaboration with Aplast, Someflu’s unit of research, development and innovation in high performance plastic molding, Someflu has just developed a first centrifugal pump made of thick parts using one of the most technical advanced resin on the market: The PEEK. Someflu recently increased even further the use of polymer resins for handling corrosive and aggressive medias by providing a new solution to critical applications. We specialize in using PEEK Material to manufacture PEEK profiles, modified PEEK sheets, products and injection molded parts with the highest technology and stable quality control.

This situation demands for use of carbide-tipped tools for machining of a normal grade of PEEK and diamond-tipped tools for carbon fiber reinforced PEEK grades. PEEK grades that are reinforced using carbon fiber have a more adverse effect on tools. Both petroleum-based and water-based coolants can be used.Īnother important factor to consider is tool abrasion during machining PEEK as compared to machining other few Plastics compatible. These preventive measures include peck drilling, coolant-fed drill bits, and the usage of enough coolant during all of the machining processes. That calls for employing techniques to avoid problems due to inefficient heat dissipation by the material. PEEK, high-heat engineering plastic, does not dissipate the heat produced during the machining process adequately. This necessitates the usage of fixtures during machining to ensure accurate machining. PEEK is considerably stronger and stiffer than most polymers, but softer than most metals. These requirements differ based on the grade of PEEK materials being used and complete details in this regard are provided by the manufacturer of that certain grade. Before starting the machining process, there are special annealing requirements that must be met to avoid internal stress and heat-related cracks during machining. PEEK machining provides high accuracy and repeatability.ĭue to the high melting point of PEEK, faster feed rates and speed can be employed during the machining process as compared to other polymers. Medical grade, as well as industrial grade PEEK, can be machined. Mold PEEK materials can be machined to obtain complex geometric profiles. The main advantage of these machines originates from the ability to control the machine through computer-generated code through advanced controllers.ĬNC machining offers the opportunity to create geometries, which are complex while meeting the required geometric tolerance limits, of different materials ranging from plastics to metals. CNC (Computer Numeric Control) machining consists of different variants of multi-axis milling, turning, and Electric Discharge machines (EDM) to obtain desired geometric profile.
