Product Information

The products are made of high quality alloy steel production. The plates are punched and squeezed bores by precision technology. The pin, bush, roller are machined by high-efficiency automatic equipment and automatic grinding equipment, then through heat treatment of carburization, carbon and nitrogen protection mesh belt furnace, surface blasting process etc. Assembled precision by Internal hole position, spinThe high precise CNC equipment, such as Slow-feeding wire-cut machine, jig grinding machine and electric discharge machine, ensures the top quality precision of mould processing, with the high efficient and environmental protection acid rolling line being the largest raw material converting equipment in the field in china; The wildly use of automFirstly: innovative product engineering. We are continuously improving well-proven and established products in the areas of drive and conveyance technology or are looking for possible innovations. One example for this is the maintenance-free chain. Secondly: excellent production engineering. Our production processes are also constantly improved upon. Quite frequently effective, new products are only possible because of innovative production methods. Thirdly: competent application consulting.atic milling machine, high-speed automatic feeding punch, high speed automatic rolling and assembling machine guarantees the high quality and efficiency of components and chain making. riveted by pressure to ensure the performance of the entire chain.
