Our experienced auditing teams and subcontractor selection teams work within the factories and at subcontractors to assure that our quality control standards are met.
Once you decide to move forward, Welle holds an APQP meeting to review all project drawings and critical dimensions. We cover timelines, packaging, and any inventory requirements. The factory’s engineers meet to review drawings and critical dimensions, re-evaluate quality systems, confirm PPAP levels, process capabilities, and communicate your specific requirements.
We provide you with digital photos of tooling progress and frequent status reports. There are also opportunities for you to have video conferences with any of team members.
While not required, there is an open invitation for your team to visit the factories at any time during tooling and production.

WELLE has passed ISO9001:2015,To ensure quality, most of our manufacturers are required to pass international quality certifications such as ISO/TS16949, ISO14001, etc. and the quality of products is guaranteed to meet customer requirements.

General Machining Tolerances on metal to +/- 0.005″ (+/- 0.127 mm) following ISO 2768 unless otherwise specified. Plastics and composites will be +/- 0.010”(+/- 0.254 mm).

Welle offers a precise match between customer specifications and supplier capacity with a tolerance level of up to 2 microns(±0.002mm).

For the 3D drawing, we would prefer STEP, IGES, or X_T format. For the 2D drawing, we would prefer PDF format there are tolerances with the dimensions if possible.
