FAQs About Our Manufacturing Services

We are a direct manufacturer. We operate our own production facilities, giving us full control over quality, scheduling, and pricing without middleman costs.

Our standard lead times are 1–3 working days for samples and 3–7 working days for bulk production, subject to order volume and part complexity.

Simply provide your technical drawings (2D/3D CAD), reference photos, or physical prototypes. Our engineering team will evaluate the manufacturability and provide a detailed quote and feasibility assessment.

We adhere to strict Intellectual Property (IP) protection protocols. We are fully prepared to sign a Non-Disclosure Agreement (NDA) before receiving any sensitive data to ensure your proprietary designs remain secure.

We operate under a rigorous Quality Management System (QMS) aligned with ISO standards. Our process includes material verification, in-process monitoring, and a final 100% inspection prior to shipment to ensure zero defects.
