About nier Chairman's speech







Yangzhou Nier Engineering Plastics Co., Ltd, a professional manufacturer of MC nylon elevator driving sheave, integrating R & D, Production and sales as one, was set up at Genggeng Industry Park Baoying Jiangsu Province in 2004.

As a new type of engineering plastics, MC nylon has many advantages such as light weight, high strength, self-lubrication, low creep, wear resistance, anti-aging, shock absorption and noise reduction. With the assistance of relevant scientific research institutes, Nier has successfully developed MC Nylon elevator driving sheave, which is used as guiding sheave, counterweight sheave and crosshead sheave. It is generally applicable to passenger elevator, freight elevator and villa elevator at the speed of 0.5-3.0m/s. The development created a precedent for the application of MC nylon material on elevator driving sheave in China, and achieved the innovative aim of “Plastics substitute steel, technology environmental protection”. The product performance meet or even exceed the standard requirements after testing by Shanghai Jiaotong University testing center and Shanghai Plastics Research Institute testing center. Nier testing center is equipped with tensile testing machine, dynamic balance testing machine, Vicat softening point tester, impact testing machine and so on. Nier has got CE certification, Rosh certification, WCA certification and ISO9001 quality management system certification, ISO14001 environmental management system certification, OHSAS18001 occupational health & safety management system certification.

After years of development, Nier has centrifugal casting machine, heat treatment kettle, CNC lathe, machining center, hydraulic press, laser cutting machine, laser cutting robot, welding robot, CNC punching machine, plate shearing machine, bending machine, shot blasting cleaning machine, sawing machine, drilling machine, spraying line and other processing equipment and production lines more than 200 sets.

Since its establishment, Nier set up a long-term strategic cooperative partnership with almost 200 enterprises. Until 2020, Nier has sold more than 3,500,000 sets Mc nylon sheaves to the market, keep on maintaining the leading role in MC nylon elevator driving sheave manufacturing in China.

With many years of development, Nier has a complete technical evaluation system, strong R&D testing capabilities and innovative technology R&D team. Every year, Nier invest special fund to develop new products and build school-enterprise relationship with Zhejiang University and Sichuan University. Up to now, Nier has built “Corporate Academician Workstation” and “Jiangsu Provincial Graduate Workstation” and has many MC nylon elevator sheaves with independent intellectual property rights. The company and its products successively got the title of “National High-tech Enterprise”, “Jiangsu Provincial Special Engineering Plastics Research Center” , “Jiangsu Enterprise Technology Center”, “China Famous Brand”, “Jiangsu Famous Brand Products”. Nier has become one of the major suppliers of elevator manufacturing industry at home and abroad. 

Facing the future, Nier, as always, stick to the elevator manufacturing industry as its market, take responsibility for providing products with environmental and technological, rule with “High Quality, Time Delivery, Excellent service, Win-win cooperation”, unremitting efforts to provide you with quality products and sincere, professional services.

Nier welcomes you!
