1. surface treatment process: in the process of manufacturing the electroplating arm, a basic material will be used to manufacture the main part of the arm, and then the electroplating process will be carried out. However, there is no electroplating process for ordinary arm devices, and they are usually made directly from one material.

2. Experience: Electroplated handrails are usually superior to ordinary handrails in terms of color, appearance, durability and safety. Electroplated arm strength device is relatively more durable, has excellent safety performance and mechanical strength, and can be reused for a long time.

3. Use: Ordinary arm exercisers are mostly used for park fitness equipment, small household tensioners, etc. Electroplated torque arm device is also used to fix and maintain cables of sports equipment, fitness equipment, toys, electronic communication instruments, automobiles, ships and bridges, tension sheaths of cable guide ropes of suspension bridges, repair and casting of industrial pipes with sunken keel in shipbuilding industry and other fields. , and has shown good promotion potential and broad development prospects.
