China High Performance Friction Liner with Imported Material

China Industry Luoyang Engineering Plastic Co., LTD (CIPC) , named previously as Engineering Plastic Factory of CITIC Heavy Machinery Industry and Commerce Co., LTD, which controlled by CIC Luoyang Heavy Machinery Co., LTD and has established on Jan. 12th, 2010 with 16,000 thousand RMB registered capital. With CIPC establishment, all the sales businesses, qualifications and intangible assets of Engineering Plastic Factory of CITIC Heavy Machinery Industry and Commerce Co., LTD have been owned and undertaken by CIPC. CIPC has specialized in research, development and production of engineering plastics, and the teaching and science research base of mining friction material of China Mining University, production-teaching-research base of Henan Science and Technology University, and CIPC is one of members of China Heavy machinery Industry Association (CHMIA).

CIPC is the first company to produce high performance friction liners. Our products can be found almost in all Chinese Mines by equipped in the hoists of CITIC Heavy Machinery Co., LTD, being supplied to Shanghai metallurgical Mining Machinery Factory, Sichuan Mining Machinery Group Co., LTD, Rieter Hunan Coal Mining Equipment Co., LTD, Chongqing Taifeng Mining Machinery Co. LTD, Jinzhou Mining Machinery Group Co., LTD, Guiyang Gaoyuan Ming Machinery Co., LTD, etc., and occupied 90% of all domestic and international markets.

With the technological improvement of hoist, higher requirements on its auxiliary components become more and more. Our Products servicing in mining feedback us much information which promote us to adjust our product structure and develop new products by our high level r&d team and the national first-class testing equipments. At present, more diversified product structure and more satisfactory performance must bring our CIPC shining brightly all over the word
To fulfill the new requirement of large and super - large multi - rope friction hoist , our company using the Germany imported raw materials produces GDM326 high performance friction liner with imported material, mainly matching the imported hoist, domestic large and super large hoist and meeting other needs.

Compared with other liner, GDM326 high performance friction liner with imported material has been greatly improved in the friction coefficient, compression resistance, abrasion resistance, stability etc., so it has been adopted and trusted by a great number of users and brought good economic benefit. GDM326 high performance friction liner with imported material can also be used for other machinery conveying power by friction and be used as leading wheel friction liner of funicular.

Technical Characteristics
1. All the friction coefficients of GDM326 in various conditions are more than 0.28, which completely fulfills the requirements of multi - rope friction hoist.
