POProduct Information

Flexible combine chains

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.
Made from the steel and the up-to-date skills as well as precision procedures, the combine 
chains can withstand strong pressure and high temperature.
