Different Types of Stamping: Processes & Applications

Stamping is a metalworking process that uses a press and a die to shape, cut, or form metal sheets into specific parts. The type of stamping method used depends on factors like production volume, material type, precision requirements, and part complexity. Below are the most common types of stamping processes:

1. Progressive Die Stamping

Overview: A high-speed, automated process that feeds a continuous strip of metal through multiple stations within a single die.

Advantages:

• High-speed production – Ideal for large-volume manufacturing.
• Minimal scrap – Optimized material usage.
• Consistent quality – Ensures precision in mass production.
• Cost-effective – Reduces labor costs due to automation.

Best Applications:

• Automotive components (brackets, clips, terminals)
• Electrical connectors and contacts
• Small metal parts in appliances and electronics

2. Tryout Presses

Overview: Used for testing and refining dies before mass production.

Advantages:

• Ensures die accuracy before production.
• Reduces downtime by identifying issues early.
• Saves costs by preventing defective batches.

Best Applications:

• Automotive and aerospace die testing
• Fine-tuning complex dies for progressive and transfer presses
• Prototyping new stamped parts
