03 — Why Caldwell
Bridging the gap in language, culture and quality
Sourcing overseas usually means choosing between price and peace of mind. Owning the factory on both sides lets us give you both.
American Owned
Owned and managed by an American from Iowa. You talk directly to someone who understands what your customers expect.
Thailand & China Pricing
Owning factories in both countries lets us quote the better landed cost on volume orders.
Confidential
Invest in tooling with us and your design is yours. We never list it on our sites or take it to trade shows. NDA signed on request.
Customized
Work from a drawing or a physical sample. We ship worldwide — customers in the US, Canada, Germany, New Zealand and Australia.

05 — The process
From first message to volume production
Tell us about the part
A short message is enough — existing part or brand new item. We can sign an NDA first.
Send drawings or a sample
We quote the part and tell you plainly whether tooling is required.
Prototype & final pricing
Once tooling is confirmed we build a prototype and lock in final pricing for your approval.
Volume production
We work with your freight forwarder, or ship FCL or LCL direct to your door.
