As-cast housing showing top-side parting line before polishing and buffing.

The casting is trimmed of gating, overflows, and external flash with an upper compound trim die.

  • The trim die is precision machined by EDM (electro-discharge machining) for exact fit and precise alignment during the trimming operation. 

Internal flash in the bore is trimmed with a cammed cutter. 

The top and bottom parting lines on the casting are polished and buffed for a smooth surface finish.
