OEM FAQ
Do you manufacture to our drawings?
Yes. Everything is made to customer drawings and specifications; we do not sell catalog products.
Can one supplier handle molds, parts and assembly?
Yes. Tooling, molding, die casting, CNC machining, finishing and sub-assembly are done in the same factory under one ISO 9001:2015 system.
Can you take over production from another supplier?
Yes. We check transferred molds on arrival, run samples and a first article check, and then release production.
