PEN / DRAWING REVIEW
DRAWING FIRST. PROCESS SECOND.
We review manufacturability, confirm critical dimensions and define a datum strategy before production begins. For high-end custom pens, we align the control plan to concentricity, thread feel and cosmetic finish.
- DFM review and risk assessment
- Critical dimensions and GD&T verification
- Tolerance stack-up and measurement plan
CAPABILITIES
DIFFICULT MATERIALS.
CONTROLLED RESULTS.
Material range
Aluminum, stainless steel, titanium, brass, Damascus steel, PEEK, PEI, acrylic, resin, celluloid and PCTG.
Surface finishing
PVD, painting, anodizing, sandblasting, plating and project-specific cosmetic finishing.
WHAT WE OPTIMIZE
NOT JUST A GOOD FIRST PART.
A STABLE PROCESS FOR EVERY PART.
01Qualified setup
Datums, fixtures and offsets established before production release.
02Visible variation
Critical characteristics remain measurable throughout the run.
03Documented approval
Inspection evidence supports repeat orders and engineering review.
QUALITY BY DESIGN
MEASURED.
DOCUMENTED.
REPEATABLE.
ISO 9001 quality management supports first-article, in-process and final inspection. When the drawing demands it, tolerance capability can reach ±0.001 mm.
- Critical-feature inspection planning
- Material and finish traceability
- Repeat-order process records
