Aluminum Clamping

[PVCSKI]

Is there a special formula for clamping aluminum proto or production tools.

I have always used the same torque specs. for aluminum molds as I use for tool steel. Have ran a lot of aluminum protos and limited production tools over the years, never had problems clamping them in. Same with tonnage requirements, use minimum tonnage necessary to produce good parts whether aluminum or std. tool steel.
