Always check with the CPC supplier for screen-pack and die clearance
For blow molders who make multiple product changes, adjustments must be made to the equipment's pin and die clearance
to accommodate the wall thickness of various parts.
the effect of varying die clearance
is evident when the machine is full, whereas it is insignificant when it is partly loaded (polymer mastication stage);
These dies are designed for high performance punching of thin sheet metal where the recommended die clearance
is less than 0.
The critical need is to maintain a minimum die clearance
at all times.
While the bulk of the tools in the turret are standard tools and do not change, pre-built die cassettes with different die clearances
provide flexibility to react to customers' needs.
for fineblanking can be held much tighter than stamping, promoting smoother and straighter edges on parts.
Tool changes typically require the operator to recalibrate pin and die clearances
using a programming cylinder that operates at 2000 psi.
