On the floor

Your idea, our manufacturing

Send a photo, a drawing, a physical sample or a competitor product. We confirm what is possible, what it costs and how long it takes — in writing, before you commit to anything.

Your requirement

Photo, sample, drawing or spec sheet — plus target quantity, market and price.

Feasibility & quotation

We confirm material, capacity, decoration method and tooling, then quote price, MOQ and lead time.

Sampling

A pre-production sample with your logo and colour. Sample cost and timing quoted per project.

Approval

You sign off the sample. Specification sheet and artwork are locked before production starts.

Mass production

Injection, vacuum body processing, assembly and logo application — all in our own plant.

Quality control

In-line checks during the run, then a final inspection against your approved sample.

Shipping

Export cartons or your retail packaging. FOB Ningbo / Shanghai, or to your forwarder.
