FAQs
Quick answers on manufacturability, lead times, materials and quality documents.
After you send CAD, our engineers review geometry, wall thickness, tolerances and fixturing, then suggest process routes and optimizations to reduce rework and shorten lead time.
We run our own climate-controlled shops and metrology lab focused on precision CNC. Standardized processes, documented quality, dedicated owners and complete quality packs for semiconductor, medical and other demanding uses.
It depends on complexity and quantity. Standard precision parts can be prototyped quickly; production lots lock process and critical dims before scheduling. Share drawings, material and qty for a firm lead time.
Yes. On request: mill test certificates, RoHS docs, dimensional data, CMM reports and FAI — with shipment or before ship.
Parts go through trial, inspection and customer confirmation before ship. If anything is off, we follow our quality procedure and quickly agree a recovery plan so your schedule stays on track.
