Progressive die stamping enables high-volume production of complex parts. Proper setup is critical for success.

What is Progressive Die Stamping?

A metal strip feeds through multiple stations, each performing a different operation until a finished part is produced.

Typical Station Sequence

1. Pilot hole piercing
2. Notching and slotting
3. Forming and bending
4. Coining or embossing
5. 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

Quality Control

First article inspection, hourly sample checks, SPC monitoring for critical dimensions, automated vision systems for high-volume production.

Photoelectric sensors create an invisible barrier. Press stops immediately if beam is broken during operation.

Specifications: Resolution ≤30mm, response time <25ms, height coverage per risk assessment

3. Pressure Relief Valve

Prevents overloading by releasing hydraulic pressure when system exceeds rated tonnage. Protects frame, cylinder, and tooling.

Setting: 110-115% of rated pressure, calibrated annually

4. Emergency Stop System

Red mushroom-head E-stop buttons at multiple locations. Must cut all power and dump hydraulic pressure immediately.

Requirements: Category 0 stop (immediate), hardwired (not PLC-dependent), manual reset

5. Mechanical Safety Blocks

Physical blocks that support the ram during die changes and maintenance. Prevents accidental descent.

Usage: Always engage before entering press, rated for full tonnage

Safety Standards Compliance
