Performance Highlights
End-to-end in-house capability
Die design, manufacturing, heat treatment, and surface coating are all performed in-house. No external coordination delays - faster development cycles and consistent quality control.
Carbide expertise
We work with multiple carbide grades and select the optimal material for each extrusion application - balancing toughness, abrasion resistance, and compression strength.
Heat treatment and surface engineering tailored to application
Processes are customized for each die type and material, ensuring optimal hardness, wear resistance, and anti-galling performance.
Validation on our own production lines
All extrusion dies are validated on our own production equipment before release - ensuring performance data reflects actual forming conditions.
Full maintenance support
Die reworking, repair, and refurbishment are performed in-house, reducing downtime and extending die life across multiple production cycles.
IATF 16949-certified facility
Quality systems aligned with automotive industry requirements.
Applications
Aluminum Extrusion Tooling
Dies for aluminum profiles and structural components - designed for controlled material flow and consistent profile accuracy.
Steel Cold Extrusion Tooling
High-strength steel components - dies with carbide inserts for extended service life under extreme pressures.
Vertical Integration Advantage
We control every stage - design, manufacturing, heat treatment, surface coating, and maintenance. This eliminates external dependencies, ensures consistent quality, and allows direct feedback from our own production lines to drive continuous die improvement.
