DEPENDING ON:
WHEN YOU MUST OR YOU CAN USE IT
ADVANTAGES DISADVANTAGES
STARTING IN PROGRESSIVE AND
FINISHING IN TRANSFER
-IF THE EQUIPMENT ALLOWS IT.
-IF AT THE END THE PART MUST BE TREND AND BENDED.
-HIGH PART PRODUCTIONS.
-MORE ECONOMICAL DIES
-POSSIBILITY BENDING PART EDGE IN FLOW.
- IN SOME PARTS MORE SCRAP.
-LESS PRODUCTION RATE THAN IN PURE PROGRESSIVE.
TRANSFER STARTING FROM COIL
- PART TIEFER THAN PROGRESSIVE
-MORE ECONOMICAL PROCESS.
-GOOD PRODUCTION RATES.
-SMALL TO MEDIUM PARTS.
- BLANK LOADER NOT REQUIRED
-COIL IS EASIER TO BUY.
-CAN BE ALSO USED AS PROGRESSIVE
- SCRAP COULD BE HIGH.
-COIL STORAGE AREA.
-COIL CHANGE TIME
TRANSFER STARTING FROM BLANK
- WHEN THE PART REQUIRES BLANK
- BY MAKING GOOD USE OF MATERIAL
- MORE OPERATIONS IN THE SAME BOLSTER SIZE.
-LESS SCRAP.
-BLANK CHANGE TIME
- LESS PRODUCTION.
-BLANKS TO BE BOUGHT OR PRODUCED

Adapt the speed during the work:
Reduce the drawing speed, more part quality
Increase the feeding speed
