The Linear Actuator parts material and heat treatment are the basic guarantees for high-quality Ball Screws and Planetary Roller Screw. We obey the superior alloy steel and the molding process must be spraying, not casting. Strictly required to use a two-ball, two-draw process, and the eutectic carbide must reach level 1 for Ball Screws Assemblies.
After the materials need to be undergone a cold pressing process similar to "forging" to further optimize the metallographic structure.
The cold-rolled screw blank diameter also needs to implement a self-developed hard rolling process to minimize the heat treatment deformation for Ball Screws Linear Actuator.
