Bo,
I thought what you described was called compression molding!?!?
I always thought that 2-Stage clamping was simply the definition of the platens full motion, split up to 2 separate set of parameters. My understanding is this:
- The first stage was a high-speed, low pressure motion, using a mold protect feature, to get the mold to within a predetermined distance from fully closed. Its only function is to reduce processing time, essentially.
- Stage two was low speed, high pressure for applying clamping tonnage.
Am I wrong on this???
