Source of the company's main products are deep hydraulic cylinder and cylinder seals, automotive seals, of course, including all kinds of rubber products. Are: 
 (A) the import of seal hydraulic polyurethane raw materials, such as: UHS, UN, UNR, UHR, UNP, Yx, KY, and DH, FC dust, etc.; 
 (B) the production of PTFE hydraulic seals, such as: circle with a square hole (box to circle), ladder ring shaft (Manchester seal), CST combination of letters, GDKK combination of letters, GKDF combination of letters, with the rotation axis square circle, a square hole with the rotary ring and oriented with the (ring), ring, etc.; 
 (C) the production of hydraulic rubber seals, all kinds of shaft, loop holes, such as: U, Y, Yx, KY, QY-shaped ring and all kinds of dust, etc.; 
 (D) the production of rotary sealing rubber material, such as: seal, oil seal, etc.; 
 (E)-based seal, such as: O-ring, star ring, washer, and so on. 
 (F) cloth phenolic resin, nylon, POM, and the production of PTFE support ring, guide sleeve, oriented band, ring, etc. Localization of imported seal is Mingyu's a major feature of the company's products are actually the source depth can be used to seal any necessary occasions. Source of deep company's products are widely used in: 
 (A) construction machinery, such as: loaders, bulldozers, forklifts, excavators, etc.; 
 (B) mechanical stress, such as: injection molding machines, molding machines, die-casting machine, forming machine tools and various types of pumps, valves, etc.; 
 (C) construction machinery, such as: sweepers, garbage trucks, road rollers, etc.; 
 (D) of wood-based panel machinery and electronics, metallurgy, mining, hydropower, marine and other industries. Current cooperation, supporting the well-known companies: Xiamen Engineering shares, Long Engineering (Shanghai) shares, Volvo temporary workers, Liugong shares, Sunward, Sany, Zoomlion, Changzhou Hyundai. 
 Source of deep domestic company's products not only sell, but also some export (object are directly supporting manufacturers). Exporting countries were: Austria, Spain and Singapore. 
 Excellent sealing performance, in addition to a reasonable seal structure, the other major factor is the sealing material. The company has a deep source for the user to choose different materials, such as: imported polyurethane (with Germany, Spain, Japan and other raw materials of different brands), polytetrafluoroethylene (the country's top selection of materials or the United States, Japan imported raw materials), cylinder with a rubber blends, NBR rubber, fluorine rubber, silicone rubber, polypropylene ester rubber, ethylene-propylene rubber and nylon, POM, cloth phenolic resin. 
 As with international standards, the requirements of various industries on the seal continues to increase, so deep has been working with the source, moving in the direction of high-quality seal. Only hope to bring the user is always the highest quality sealing components. 
 Company will be the source of deep innovative technology, strict control and a wealth of experience, so that the hydraulic system does not always remain close through the "seal."
