Our Process

From Design to Production in 4 Steps

A streamlined workflow ensuring quality, speed, and transparency at every stage.

Analysis

We study your requirements from an idea, CAD data, or reference samples, then evaluate feasibility, materials, and the manufacturing approach.

DFM feedback

Planning

Detailed timing plans are reported to you weekly, with mold flow analysis and production scheduling to keep delivery on track.

Weekly reports

Mold Trial

T0 prototype parts in 3–5 days with soft tooling; production hard tooling is completed in 4–6 weeks. FAI and dimensional reports included.

T0 in 3–5 days

Mass Production

ISO 9001 and IATF 16949 controlled production with in-process inspection, SPC, and full traceability from raw material to finished part.

Full traceability
From Concept to Mass Production
