Aluminum Die Casting – Surface Finish Guidelines

When a part is sent out for quoting to die casters there are some very important issues that need to be discussed and agreed upon between the purchaser and the die caster.

The added operation will of course add cost so that must be addressed during the quote process so the customer knows what to expect long term.
