Engagement Timeline

From first drawing to qualified production — every phase documented.

Six phases. One supplier. No subcontracted tooling, no mystery in the process.

Engineering drawing review on drafting table with technical specifications
Phase 01
RFQ Receipt

Every program starts with geometry and a tolerance stack.

Submit your 2D drawing, 3D STEP file, or part specification. Our engineering team reviews material class, durometer, cross-section geometry, and functional requirements within one business day. No NDAs required for initial review.

Accepts: DWG · STEP · IGES · PDF spec sheets

Phase 02
DFM Review

We redesign for manufacturability before a single tool-path is cut.

Design for Manufacturability analysis covers gate placement, flash line optimization, parting surface geometry, post-cure shrink prediction, and secondary operation feasibility. We return a marked-up drawing with recommended changes — or a clean approval if your design is already optimized.

Covers: gate · flash · shrink · draft · secondary ops

Tool Design & Build

P20 and H13 tooling machined to ±0.0005" on our floor.

We design and build all tooling in-house on Mazak and Okuma 5-axis machining centers. Cavity dimensions are verified by CMM against the approved part drawing before heat treat. Standard lead time for production tooling is 4–6 weeks from DFM approval.

T1 Sampling

First article parts in your hands with dimensional data attached.

T1 shots are run at documented process parameters. Every cavity is measured against the part drawing using CMM and optical comparator. You receive a full dimensional report, material cure verification, and Shore hardness data — not just a bag of parts.

Reports: CMM · Shore A/D · specific gravity · tensile

PPAP Submission

Level 3 PPAP packages ready for your supplier portal.

We prepare and submit complete PPAP documentation including design records, process flow diagram, PFMEA, control plan, MSA, initial process capability study (Cpk ≥ 1.67), and PSW. Compliant with AIAG 4th edition and AS9102 first article requirements.

Standard: AIAG 4th Ed · AS9102 FAI · NADCAP-ready

Sustained Production

A qualified production line is a partnership already in motion.

Production runs are governed by an approved control plan. SPC data is collected at defined sampling intervals. Certificate of Conformance accompanies every shipment. Annual re-validation keeps your supplier qualification current. We flag process drift before it becomes a nonconformance.
