Structure transform

We can provide customers structure transforming on stamping parts, welding parts

to castings which will improve the service life of the product and reduce the product cost.

Applications

This housing is designed to protect the internal mechanism of limit switches used in automation, material handling, and process control systems.

• Industrial limit switches

• Position sensors and proximity switches

• Safety interlock devices

• Valve position indicators

• Conveyor and crane control systems

What is Pickling & Passivation

After casting, the 304 stainless steel housing undergoes pickling and passivation to remove oxides, free iron, and surface contaminants. This restores and enhances the natural corrosion-resistant oxide layer, ensuring long-term performance in wet, chemical, or outdoor environments.
