2. New Custom Product Development Workflow at Aleader Tires

Step A: Project Evaluation & Design Consultation

We start with your provided technical drawings, physical samples or detailed functional requirements. Our engineering team will complete custom design work, draw technical schematics and finalize full product parameters for your review and confirmation.

Step B: Technical Drawing Output

Once you approve our initial design proposal, we will release complete sets of official drawings, including mold drawings, assembly fitting drawings and finished wheel reference drawings, together with standardized technical specs.

Step C: Mold Fabrication & Initial Sample Testing

We send finalized mold blueprints to our mold workshop to build tooling. A 50% deposit for mold costs will be required before production starts. Once molds are finished, we run initial mold trials, verify mold accuracy and manufacture test samples for full performance testing.

Step D: Pre-Production Sample Approval

We will produce finished prototype samples and ship them to you for full inspection and final sign-off.

Step E: Small-Batch Trial Run

After you confirm prototypes meet all requirements, we suggest a small trial production order. This helps us verify consistent production stability, lock down the official master production drawings, and seal matching reference samples for both sides.

Step F: Official Mass Production

We begin full mass production strictly following all mutually agreed standards. You will complete final mold acceptance inspection, then settle the remaining 50% mold balance payment after successful acceptance.
