Before you order
Send the machine serial number or a photo of the worn part if the model is not certain. Cavity, tooth profile and hardness all change with duty conditions, and a wrong profile is a wasted casting.
Every batch ships with a material test report carrying the heat number; third-party inspection (SGS, BV or CCIC) can be arranged at cost.
