Frequently Asked Questions
Are you a factory or a trade company?
We make export ourselves but are more than a trade company - we
specialize in engineering spare parts. We have many experienced
factory partners and get involved in every production process. Once
you place an order, we handle everything to ensure timely delivery
of quality parts.
Do you make customized products or finished parts?
All parts are custom made according to customer drawings or
samples. We can consider stocking items when customers require.
Will my drawing be safe after you get it?
Yes, we will not release your design to third parties without
permission. We can sign an NDA before receiving your drawings.
What is the MOQ?
We typically don't set MOQ, but larger quantities receive better
pricing. We're happy to make prototype parts or samples to ensure
quality standards.
Can you provide samples?
Yes, we require sample costs which will be returned when proceeding
to mass production. For molded items, we charge mold fees which
then belong to the customer.
How do you handle quality issues?

of non-conformance, contact us immediately with photos. We will
resolve issues promptly, covering any resulting transportation
costs.
