Standard Shot Sleeve Processing Procedures


Our processing procedure for Reconditioned Cold Chambers is as follows:

• Sandblast
• Polish hone to remove excess debris in ID
• Visual inspection of OD for cracks and ID for washout and erosion
• Quote Not-To-Exceed cost for each Cold Chamber
• Gauge bore for straightness
• If Polish Only: emery clothe ID or if straightness needs to be addressed, remove ID stock to
next .020" increment and emery clothe accordingly
• If bore sufficiently damaged: remove ID stock past the current layer of nitride and all other ID
defects. Hone to an even .020" increment.

• Polish ID with emery clothe and gauge for final check and inspection
