Why programs land here

  • 25-45% cost reduction against comparable US and European sources on suitable parts
  • Tooling in 2-5 weeks, first articles in approximately 35 days
  • Roughly 50 days purchase order to receipt, door to door
  • Single-source from development through molding, stamping and assembly
  • 23 miles from the Port of Shanghai, which keeps inland freight and transit variance down

Lead times are typical rather than contractual and are confirmed per program at quotation.

On certification, stated plainly.

This plant holds ISO 9001. It does not currently hold IATF 16949 or ISO 13485. For automotive programs that require IATF, or medical work requiring ISO 13485, we will route you to the appropriate plant rather than talk around the gap. See the full certification matrix →
