About Us

YOUR RELIABLE SOURCING AGENCY IN ASIA

We value every project customers put into our hands. From initial inquiry, we meticulously investigate a part's structure  and provide customers with a manufacturability report. We offer the most practical engineering solutions based on our decades of manufacturing experience. Always, we make sure our customers understand and approve every action we take.

During fabrication, we keep our customers up to date and are immediately available to address any concerns. We are committed to total transparency; that is the key to winning our customers' trust.

During a mold trial or part quality check, we provide corresponding reports to obtain customers' approval before shipping overseas.

MAKING A POSSIBLE MOQ

We are always excited to work on new designs! We understand most projects begin with lower demand. Sometimes a sizeable investment in mold building and considerable MOQ bogs down a project early on. Longwin Custom Supplies Ltd. is eager to provide alternatives and solve engineering issues to arrive at a feasible and economical process that will bring your ideas to life.
