The ultimate solution for abrasion and wear:

1. High strength alloy steel with tempered and nitride.

2. Overlay of nickel-based and molybdenum-based alloys on vulnerable screw parts with a thickness of 1 to 1.5 mm. Effectively provide 1.5 times longer service life.

3. hard chrome plating is an optional process.

Production time:

Within 15-28 days depending on the complexity of the part.
