Manufacturing
40Cr,42CrMo, C45,stainless steel and so on are available.

laser cutting

Laser cutting is a technology that uses a laser to cut materials. Use high-power density laser beam irradiation to cut plates, often used in thick plates (above 20mm), small batch chain plates, super-pitch chain plates (above 400mm), special-shaped chain plates, etc.

Chain hot riveting head

Hot riveting is more solid riveting, by quickly heating the pin head and pressing the riveting. It is often used for thick pin (above 25mm) and high-hardness pins (above 55HRC).

Multipurpose furnace heat treatment

ZMIE take the Multi-purpose furnace to make the heat treatment, carburizing and tempering by whole piece. Compared with the pit furnace and mesh belt furnace, this heat treatment method is used more extensive, meanwhile, it can make heat treatment for all the components of chains. Therefore, the quality will be more stable after treatment.

Induction heat treatment

ZMIE induction hardening is a heat treating process by hardening the pin surface as well as retain core hardness. This increased depth of hardness of induction harded parts has been proved to greatly increase the wear life and fatigue resistance.

Welding robot

ZMIE welding robot is an automatic welding equipment that can rotate and substitute movement. The welding robot not only improves the welding quality, but also ensures the stability and uniformity of the welding.

CNC machining center

CNC machining center is a kind multifunctional machine, who finishes the milling, drilling, boring, tapping and other processing by automatic tool change. The quality of the CNC machining center is stable and with high accuracy.

Progressive die Southern punch chain plate

ZMIE progressive die stamping is a metal forming process widely used to produce parts of various industries, specially the plate of the stanard roller chain, which can encompass punching, coining, bending and several other ways of modifying metal raw material. Each station performs one or more operations until a finished part is made.

Pre-tension(standard chain is very important)

ZMIE chain Pre-stretching takes an important role during the chain manufacturing. After Pre-stretching, the chain not only improves the chain length accuracy and reduces the elongation of the running of chain, but also eliminates the mismatch between the chain plate, pin and bush. Uniformity. The pre-tensioning force is generally 30% of the breaking load, and the Pre-stretching time is 10S~20S. International standard ISO606:2004 request that chains such as roller chains, bush chains, plate chains, motorcycle chains, tooth chains and agricultural chains must be pre-tensioned after finished.

Inspection process

ZMIE have a standardized inspection management process. Our inspection people have more than 15 years working experience with inspection. The inspection equipments include breaking load machine, hardness machine, chain length testing machine and so on. During the entire order process, we will make at least 3 times inspection, including first inspection, middle inspection and final inspection. Zmie technician will do the real records for each batch.

Packing method
Generally, ZMIE products are packed in the boxes, wooden cases or pallets, as per the different customer's request.
