Transition smoothly from rapid functional engineering models to high-volume blanket production cycles.
Distributed global manufacturing capacity managed through an absolute, centralized quality checkpoint. Clarwe takes full ownership of quality control.
Every manufacturing lot generated across our elastic partner network is routed directly to Clarwe’s corporate quality control labs before final dispatch.
We physically verify critical dimensions, bore true positions, and surface profile deviations using Zeiss CMMs, optical vision systems, and calibrated thread plug gauges.
Your components arrive at your dock alongside full material traceability records, Mill Test Certificates (MTCs), RoHS/REACH compliance logs, and aviation-grade AS9102 First Article Inspection Reports (FAIR) upon request.

| Critical Engineering Tips | • Add 1° to 2° draft angles for deep pockets. • Avoid internal cross-holes <∅1 mm. |
• Include a 0.2 mm×45° chamfer on sharp edges. • Limit Max L/D Aspect Ratio to 10:1. |
• Wire: Avoid taper cuts >15°. • Sinker: Allow a minimum of 0.3 mm spark gap clearance for electrodes. |

For multi-axis CNC milling, our maximum physical bed travel handles components up to 2000 mm x 1200 mm x 800 mm. For high-speed CNC turning, we can process a maximum diameter of 450 mm and a maximum part length of 800 mm.
Yes. While standard geometries can be processed from step files using our general tolerance matrix (±0.125 mm), custom PDF technical drawings are required to execute tight, high-precision tolerances down to ±0.005 mm, custom geometric dimensioning and tolerancing (GD&T), or specific surface finishing requirements.
All 3D models and production prints uploaded to our secure platform are fully encrypted both in transit and at rest. File access is locked down strictly to assigned project engineers, and your intellectual property is automatically protected under a binding Mutual Non-Disclosure Agreement (NDA).
Because we anchor raw material costs securely through centralized inventory channels, all manual, engineer-verified line-item quotes remain completely locked and valid for exactly 30 days from issuance.
