Notching and slotting
Forming and bending
Coining or embossing
Final blanking

Press Requirements

Tonnage: 10-20% above calculated forming force
Bed size: Accommodate die + feed clearance
Shut height: Match die requirements
Speed: Match production requirements (80-400 SPM)
Feeding: Servo or mechanical roll feed

Setup Procedure

Step 1: Die Installation

Clean die and press bed. Use parallels for proper height. Secure with toe clamps or bolts. Check alignment with dial indicator.

Step 2: Feeder Setup

Install coil rack and straightener. Thread material through feeder. Set feed length and timing. Adjust pilot release.

Step 3: Trial Run

Run single stroke manually. Check part dimensions. Adjust die as needed. Run continuous at low speed. Gradually increase to production speed.

Common Issues & Solutions

Misfeed: Check feed timing, material tension
Part sticking: Add air blow-off, check lubrication
Burr formation: Sharpen or replace cutting edges
Dimensional variation: Check material thickness, die wear
