Product Info

Proper care and correct use of dies and punches minimize downtime, reduce maintenance costs, and extend tool life in manufacturing.

■ Importance of Dies and Punches in Manufacturing
Dies and punches are critical in metal stamping, cutting, cold forming, and high-pressure forging. The quality of finished parts depends on the accuracy and durability of these tools. Even small mistakes in installation or operation may cause:
・ Premature wear
・ Breakage or chipping
・ Misalignment
・ Production line downtime

■ Common Problems and Causes
1. Rapid Wear
・ Causes: Inappropriate material, lack of coating, insufficient lubrication
・ Impact: Rough edges, burrs, dimensional inaccuracy
2. Punch Breakage or Chipping
・ Causes: Excessive impact force, misalignment, poor installation
・ Impact: Tool damage, unexpected stoppage
3. Die Cracking or Fracture
・ Causes: Foreign particles, brittle tool material, uneven press force
・ Impact: Costly replacement and longer downtime
4. Punch Misalignment
・ Causes: Worn fixture, assembly errors, lack of position gauge inspection
・ Impact: Uneven wear, reduced lifespan of both dies and punches

■ Preventive Measures
To extend the life of dies and punches:
・ Use high-quality materials such as cemented carbide or special-grade steel
・ Keep press force within limits and monitor machine capacity
・ Clean die surfaces and remove metal debris before operation
・ Check alignment with a position gauge to prevent misalignment-related failures

■ Real-World Industry Examples
In hot forging and cold forging, where pressures reach hundreds to thousands of tons and temperatures exceed 1000°C, issues often include:
・ Punch deformation from extreme heat
・ Die fatigue under repeated high loads
・ Cracking due to misalignment

Selecting specialized dies and punches designed for these harsh conditions is essential for production stability.
