    After Submission

    What Happens After You Submit?

    Your inquiry moves through a clear project review and coordination process. We respond within 12 business hours.

    1. 01

      Drawing & Requirements Review

      We review the available drawing, material, quantity, application and open technical points. Critical dimensions and inspection requirements are identified.

    2. 02

      Process & Inspection Clarification

      We clarify the proposed manufacturing route, finish, inspection scope and any information needed before quotation. The suitable process is confirmed after engineering review.

    3. 03

      Quotation & Sample Coordination

      Where applicable, we coordinate the quotation, tooling or sample requirements and the agreed next step. Lead time is confirmed after drawing and project review.

    4. 04

      Production, Delivery & Follow-up

      After project confirmation, we coordinate manufacturing, inspection, delivery and after-sales follow-up. Inspection records are prepared as specified in the agreed scope.
