Application: Explosion proof brake motor

Production process: Pre-coated sand casting

Material: Ductile Iron (material grade as per customer’s request)

Tolerance: ISO 8062 CT8 – CT10

Surface roughness: around Ra (μm) 12.5

Explosion proof motor(Flame proof brake motor) have lot of the spare parts are made by casting.

As one of the main feature is to avoid any spark during operation, therefore, we developed a special process on pouring system to avoid the sand drop defects, slag inclusion defects and the defects which generated when the secondary reaction of ductile iron in the shells after pouring.

We can also do the finish machining in our workshop with the advanced CNC machining centers, CNC machining lathes, milling machines and boring machines etc.
