Application: Explosion proof brake motor / Flame proof brake motor

Production process: Resin Sand Casting

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

Casting Tolerance: ISO 8062 - CT10-11

Surface Roughness: Ra (μm) 12.5 - 25

It’s the Housing for a kind of explosion proof brake motor(Flame proof brake motor), as this kind of brake motor have no spark generated during operation, so it’s widely used in Coal mine, Oil and gas industry , Petrochemical and chemical industries, textile industry and metallurgical industry, etc.

Therefore, we developed the professional process for pouring system to avoid the sand drop defects, slag inclusion defects and the defects generated when the secondary reaction of ductile iron in the shells after pouring.
