What We Support

  • Material 316L stainless steel, selected for its corrosion resistance and weldability in demanding applications
  • File formats STEP, STP, IGES, IGS, X_T, X_B, SLDPRT, SAT for 3D; PDF, DWG, DXF for 2D
  • Max upload 500 MB per RFQ

How Our Process Helps You

When we receive a complete RFQ with drawings and required documentation, our standard lead time is 10–20 business days. This timeline lets you plan production and schedule deliveries without last-minute pressure. Our inspection environment stays at controlled temperature, and every report is prepared in the format your team needs. You receive parts with the tolerances and surface finish that match the project requirements.

We only accept projects that include full 2D drawings or 3D models, defined materials, identified critical features, expected quantities, required documentation and a realistic target date. This focused approach gives you predictable results and the records that support your own quality system.
