SourceDirect is an open network of Chinese manufacturers for custom parts. Each manufacturer has a structured profile with its processes, equipment, materials, finishes, tolerances and listed certificates, and every fact links to its source.

Engineers, product teams and sourcing managers who need custom parts made to their drawings, from a single prototype to production runs.

CNC machining, sheet metal fabrication, industrial 3D printing, vacuum casting and injection molding, with finishes such as anodizing, bead blasting, powder coating and plating.

Filter by process, material, finish, industry and must-have requirements, or describe your part in plain language. Results show each manufacturer's matching capabilities with source links.

Soon. The SourceDirect MCP server is coming soon. It will let your AI assistant search manufacturers and read full profiles with two tools: search_manufacturers and get_manufacturer.

From each manufacturer's own public website and materials. Every field shows its source link. Fields a manufacturer has not published show "Not stated".

"Listed" means the manufacturer states that certificate on its own website. Ask the manufacturer for a copy of the current certificate before you order.

Contact the manufacturer directly and send your drawings. Quotes, lead times and terms come straight from the manufacturer you choose, and you can compare several.

No. You agree on price with the manufacturer and pay the manufacturer's company account directly.

You stay in control. SourceDirect gives you the data; you choose who to contact and when.

Sign an NDA directly with the manufacturer before you share drawings.

Confirm the manufacturer's equipment, tolerance, inspection report, lead time and payment terms in writing. See the before-you-order checklist.

Searching and filtering are free. For heavy API or MCP use, contact us to partner.

Manufacturers with their own factory and equipment can apply through our Chinese site at sourcedirect.ai/cn/.
