Compound
Deep Draw
High-Speed Stamping
Stamping Process & Operational Scope
Press Capacity, Size & Accuracy
We have mechanical and hydraulic press capacities ranging from 2 to 100 tons, with up to 160 tons using a coil feeder. Maximum sheet size supported is 4 × 8 ft, with sheet thickness typically between 3 and 5 mm. Dimensional tolerances are maintained up to ±0.2 mm, depending on part design and process requirements.
Tooling, Dies & Lead Times
Tool and die design, build, and maintenance are handled in-house. Custom dies are made, with samples typically developed in around 30 days. Tooling-based projects generally follow lead times of 30 to 60 days, while previously tooled or press-brake components can be delivered within 3 to 5 working days
Production Volume & Component Complexity
We support short-run, low-volume, and high-volume requirements based on program needs. Progressive, compound, and multi-stage tooling enable the manufacture of intricate components with tight tolerances and complex geometries.
Secondary Operations & Surface Treatments
Secondary operations include deburring, cleaning, forming, welding, laser etching, and sub-assembly. Surface treatments such as plating, powder coating, anodizing, and polishing are supported through approved suppliers, based on component and application requirements.
