Company profile
SuZhou Dongmai New Material Technology CO.,Ltd. is based in Suzhou, Jiangsu and develops, designs, and produces special-engineering-plastic finished parts, components, profiles, and semi-finished profiles, with a focus on PAI/PEEK injection molding. The company supports PAI/PEEK material selection by recommending powder or pellet grades for application scenarios, evaluates product and mold feasibility, and provides product-design and mold-improvement proposals as well as injection-mold structure optimization and mold development. After sample confirmation, Dongmai begins batch production with injection-molded finished parts delivered on time in as little as 28 days, and it provides free technical support for mold modification when products are changed or upgraded. Dongmai describes 20 years of core-member industry experience, a 1500 m² standardized workshop, annual production volume of 100万 pieces, an internal R&D design team, customized profile extrusion, Japanese FANUC large horizontal injection-molding equipment, high-precision CNC lathes, and CNC machining centers. It has stable overseas procurement channels and works with suppliers in Europe and Japan, including material agreements with Japan's TORAY, the UK's VICTREX, and China's ZYPEEK; it also states a technical strategic partnership with TORAY for high-precision injection-molded parts and cooperation with Germany's Roechlig since 2010 on PAI/PEEK injection-part design and production. Dongmai serves aerospace, automotive, high-speed-rail, electronics and semiconductor, medical-device, energy, and industrial applications, and its examples include special-engineering-plastic design and production for a Nanjing airline, customized engine parts for a Jiangsu automobile factory, and PEEK injection parts used by a Suzhou medical-device factory.
Exhibits
Dongmai supplies PAI injection-molded parts, PEEK injection-molded parts, plastic profiles, plastic pellets, and customized engineering-plastic products and services. Its PEI range includes transparent and amber PEI and dark-yellow PEI+30%GF for electrical and electronic insulation, including many semiconductor-process parts, automotive parts, and structural parts that require high strength and hardness under temperature conditions. It also supplies SABO™ PEEK CON conductive PEEK and conductive-modified PEEK profiles combining high strength, heat resistance, corrosion resistance, and stable conductivity. For aerospace applications, PEEK can be processed into high-precision aircraft parts, and its hydrolysis resistance, corrosion resistance, and flame resistance support aircraft interior and exterior parts and many rocket-engine parts. For automotive applications, PEEK's friction resistance and mechanical properties support engine inner covers, bearings, gaskets, seals, clutch rings, and parts used in transmission, braking, and air-conditioning systems. For medical applications, PEEK is described as non-toxic, lightweight, corrosion-resistant, and close to human bone; it can withstand 3000 autoclave cycles at 134℃, and its creep and hydrolysis resistance support medical devices requiring high-temperature steam sterilization. For electrical and electronic applications, PEEK maintains insulation performance under high-temperature and high-humidity conditions and can be used for wafer-carrier insulation films, connectors, printed circuit boards, high-temperature connectors, and μg/L-level ultrapure-water transport and storage in pipes, valves, pumps, and containers. For energy applications, PEEK is described for high-heat and highly corrosive conditions, with a temperature range of -196℃ to 260℃ and pressure capability of 207 MPa, and it is stated to maintain tensile strength in seawater at 220℃ and 4.5 MPa. For industrial applications, PEEK is described as having dimensional stability, high stiffness, friction performance, no exhaust-gas generation during processing, ease of processing, and high-pressure resistance, and is used for compressor valve plates, piston rings, seals, and related parts.
