Custom manufacturing in China only works when the drawing, the material, the tooling ownership and the inspection criteria are written down before production starts. We build the brief with you, verify the factory that can actually run it, and keep the approved sample on record for reorders. One all-in quoted price, with every line confirmed in writing before any deposit.
What custom actually means here
From drawing to repeat order
What we confirm before any deposit
| Item | Why it is written down |
|---|---|
| Drawing, material and tolerance | So the quote is built on the same specification you will actually buy |
| Tooling and mould ownership | So a reorder cannot be held hostage to a tool you paid for |
| Approved sample reference | So production and later orders are checked against one physical standard |
| Artwork, markings and packaging | So cartons, labels and language match the destination market |
| Certificates and test reports | So the documents requested by your market are identified before production |
| Inspection criteria and AQL standard | So a failed batch is judged against an agreed standard, not an opinion |

Custom manufacturing questions
What is the difference between OEM and ODM?
With OEM the factory builds to your drawing and specification, and you own the design decisions. With ODM the factory starts from an existing platform and adapts selected features. The distinction matters because it changes who owns the tooling and how much of the product you are actually free to change.
Who owns the tooling and moulds?
It should be written down before any deposit. We agree tooling ownership as part of the brief and keep it on record, so a reorder cannot be held up by a tool you paid for but do not control. If a factory will not state this in writing, that is worth treating as a warning.
What is a golden sample?
The sample that both sides approve before production. It is measured, photographed and kept on record, and it becomes the reference for inspection and for every later reorder. Without it, a supplier can change a material or finish and still argue the goods match the order.
What should a custom manufacturing RFQ include?
A drawing or physical sample, material and tolerance, surface finish, quantity, destination, certificates, packaging and artwork, and the inspection standard. The more complete the brief, the more comparable the quotes — the same specification sent to several factories is what makes an all-in price meaningful.
How do you check a factory can actually make my part?
We look at the process list and equipment, the registered business scope, the scope of any certificate they hold and a sample of their inspection records. Then we verify the production line that will run the order. Certificates alone do not tell you where the goods are really made.
Drawing or sample, material, expected volume, destination and the documents you need. We reply with verified factory options and a written, itemised all-in quote.
