CLP Proving mandrels are manufactured out of a very high grade long lasting, tough Acetal compound. They are precision made and built to last.  Acetal resins are among the strongest and stiffest of all thermoplastics and are characterised by good fatigue life, low moisture sensitivity and high resistance to solvents and chemicals. Because of these properties, acetals compete and win over other plastics for this application.

CLP can manufacture custom diameters upon provision of the dimensions at (A), (B) & (C) per the table below (within the limitations of the total mass of the acetal block).
