Finishing Operations for Die Castings

Once a die casting has been ejected from the die, the casting needs to go through a number of additional operations before it can be used by a consumer. The casting needs to have its gates, runners, overflows and vents removed, be deflashed, have its surface cleaned, possibly machined, maybe impregnated, and perhaps painted, coated or plated.


This book reviews the various processes available to the die caster to remove the gates and overflows, deflash, deburr, clean and treat the surface of die castings. It will describe processes and equipment used for trimming, shot blasting, vibratory finishing, tumbling and shot peening. Very little information on these subjects has been published in either the Die Casting Engineer or at the Casting Congress - what little material has been published is listed in the bibliography at the end of this book.
