Three ways to start

Built for buyers and engineers who need parts, not a catalogue

We work best with companies that already know the part they need, or know the job the part has to do.

A

You have a drawing

Send the print, the quantity and the material. We come back with a price, a lead time and any manufacturability questions.

B

You have a sample

Send photos and measurements of the spring you use today. The factory can reproduce it or suggest a better-performing version.

C

You have a problem

Only a load, a stroke and a space to fit it in? The factory's engineers can design the part with you (ODM).

Why buy through us

Factory pricing, with someone on your side of the table

Buying direct from China is cheaper, but emails go unanswered, and specs get lost in translation. We sit between you and the factory floor so that doesn't happen.

  • One contact who answers in English, by email or WhatsApp
  • Your drawing checked with the factory's engineers before you're quoted
  • Samples approved before mass production starts
  • Follow-up on production, inspection and shipping until delivery
