Cold forging dies are subjected to high loads during forming, making crack formation at the fillet radius a major issue. OXISO’s surface treatment technology was developed to address this challenge. By imparting residual compressive stress, it significantly improves fatigue strength and extends die lifespan. This technology is applicable to all types of cold forging dies, including forming punches, ratchet forming, and mes-dog forming. Treated dies exhibit dramatically improved durability, reducing maintenance frequency and maximizing production efficiency.

■ Features
Improved Fatigue Strength: Imparts high residual compressive stress to the fillet radius, where cracks typically initiate.
Extended Die Lifespan: Improves die lifespan by 2 to 3 times compared to conventional methods.
Enhanced Processing Accuracy: Improves surface finish quality, ensuring consistent product quality.
Broad Applicability: Suitable for various cold forging dies, including ratchet forming, mes-dog forming, and forming punches.

■ Capabilities
Die Lifespan Improvement Records:
Ratchet Forming: From 4,000 shots to 8,000 shots.
Steel Shearing Blades: From 15,000 shots to 45,000 shots.
Chamfering Forming: From 8,000 shots to 13,000 shots.
Forming Punches: From 15,000 shots to 30,000 shots.
Mes-Dog Forming: From 3,500 shots to 6,000 shots, and 4,000 shots to 8,000 shots.
Enhanced Durability: Maintains stable performance even in high-load environments.

■ Application Examples
Ratchet Forming Dies: Suppresses fatigue failure, ensuring stable production line operation.
Steel Shearing Blades: Triples die lifespan, reducing maintenance costs.
Forming Punches: Reduces die replacement frequency, improving production efficiency.

The surface treatment technology for extending the lifespan of cold forging dies dramatically improves production efficiency and product quality.
