2. New Product Development Process - Aleader Tire

A. Project Assessment

Send us your technical requirements, product drawings or physical samples. Our engineers will work out product designs, technical specs and full evaluations, then share all files with you to review and sign off.

B. Release Production Drawings

Once you approve the design concept, we'll prepare a full set of technical drawings: mold diagrams, assembly drawings and finished product prints, plus all standardized performance parameters.

C. Mold Making & Pre-Production Tests

We send the confirmed mold drawings to our mold shop to start tooling. Clients pay a 50% mold deposit before we begin manufacturing molds. After molds are finished, we run initial test shots, check mold fit, make prototypes and run full performance testing to confirm everything works properly.

D. Sample Sign-Off

We produce finished prototypes and ship them to you for inspection and formal confirmation.

E. Small Batch Trial Production

Once samples get your approval, we move to small trial orders. This step lets us test production stability and lock down the official production drawings. We will both keep sealed reference samples to guarantee consistent quality for all future orders.

F. Mass Production

We start full mass production following all agreed technical standards. You'll inspect and sign off on the finished molds. The remaining 50% mold balance is due after your mold acceptance passes.
