What we solve

A drawing arrives. A shippable part leaves China or Vietnam.

Buyers come to AS Precision when a part needs tight tolerance, a second-country option, or a factory that can move from sample to batch without changing vendors.

Process

Five steps from RFQ to inspected parts

  1. Send the RFQ.
  2. Share a 3D file or PDF drawing.
  3. Engineers propose a process against your priority — price, quality, or lead time.
  4. Sample, confirm, then release production with order-status updates.
  5. Ship with material certificate, production record, and inspection report under ISO procedures.
