Post-Casting Machining and Coating

Post-Casting Machining and Coating Services

Investment cast parts come out close to final size, but tight-tolerance surfaces, holes and threads may need machining after casting. Coating may also be required for corrosion resistance or appearance. BRK Metal combines these steps in one order and delivers your part in its final condition as drawn.

Post-Casting Machining

• Turning and milling: Tight-tolerance surfaces and dimensions are finished.
• Drilling and threading: Holes and threads that cannot be cast are added.
• Grinding and polishing: Surface quality is improved as required.
• Inspection: Machined dimensions and surfaces are checked against the drawing.

Post-Casting Coating

Coatings are applied with our subcontract suppliers, and your order runs through BRK Metal as your single point of contact.

• Electropolishing: Gives stainless parts a smoother, brighter surface that is easier to clean.
• Galvanizing: Protects steel parts against corrosion with a zinc coating.
• Cataphoresis (e-coating): Forms an even paint layer on steel parts, including complex geometries.

If you need a different coating, mention it at the quotation stage and we will review it with you.
