Hot forging dies are repeatedly used in high-temperature environments, making wear and crack formation major challenges. Abnormal layers left after EDM processing weaken die performance and limit lifespan. This issue is addressed by advanced surface treatment technology, which completely removes abnormal layers and imparts residual compressive stress, significantly improving durability. This technology can be applied to a wide range of uses, including gear forming, flat dies, and oil groove forming, simultaneously extending die lifespan and enhancing production efficiency.

■ Features
Complete Removal of Abnormal Layers: Eliminates weak layers left after EDM processing, improving die surface strength.
Microcrack Suppression: Prevents crack propagation, ensuring long-term stable performance.
Significant Lifespan Extension: Doubles die lifespan across various forming processes.
Broad Applicability: Suitable for diverse forging dies such as gear forming, flat dies, and oil groove forming.

■ Capabilities
Lifespan Improvement Records:
Gear Forming: 8,000 shots → 15,000 shots.
Flat Dies: 10,000 shots → 20,000 shots.
Flashless Forming: 10,000 shots → 15,000 shots.
Oil Groove Forming: 10,000 shots → 15,000 shots.
Gear Forming (Other Type): 4,000 shots → 8,000 shots.
Improved Wear Resistance: Enhances surface strength, ensuring stable operation under high-temperature and high-load conditions.
