COMPARISION OF PARTS
S.NO DESCRIPTION OLD NEW
1. COST Rs /PIECE 15 1
2. MATERIAL FE410S FE410S
3. THK 4 3.15
4. WEIGHT (gms) 20 20
3D DIE DESIGN
CONSIDERATIONS:-
USED CATIA V5 FOR DESIGN
PROGRESSIVE TOOL BY 2 STATIONS
STD DIE SET WHICH IS IN SCRAP
COST AND CONSTRUCTION OF DIE
STRIP LAYOUT JUSTIFICATION
First Stop

FEED DIRECTION
PPO
PREFERRED BECAUSE:-MORE STRIP UTILIZATION 75% (LESS SCRAP%)SIMPLE DIE CONSTRUCTION
COST JUSTIFICATION
ESTIMATION:- TOTAL DIE COST (MATERIAL COST, MACHINING
COST,LABOUR COST,TRY OUT COST and OH 10%)
INHOUSE: 49,150/-
OFF LOAD: 10,294/-
Cost Calculated by Off Load Basis
OLD PART :- Rs 15/- per Part (As Per SAP data)
NEW PART:- Rs 1 /- per Part
COST JUSTIFICATION
B.E.P: FOR 700 EX PARTS COST We Can Get The New Die(Break Even Point)
By Running for 2 hrs; we can get 2400Parts, which take ~4 years to
consume
Consumption of The Part per Month : 50 Nos
HIGHLIGHTS
• As cutting force is <10ton we can use our 150 ton tryout press for production due to less schedule on that press.
• we can get directly 3.15mm Thk sheet
• Approximately 30 Parts Per Min.
• Reuse of Scrapped Die set is Possible
