The sourcing platform buyers use to find verified mechanical assembly and sub-assembly contract manufacturers. Free to start.
When OEMs and product companies need to outsource mechanical assembly, whether it is a complete final assembly, a sub-assembly feeding a production line, or a complex multi-component build, finding a contract assembler with the right process controls, inspection capability, and scalability takes more than a vendor list. TandemOne profiles verified mechanical assembly suppliers by assembly complexity experience, quality systems, testing capability, and industry markets served so buyers can identify the right partner and send a Structured RFI that covers the full scope of the engagement.
Work instruction capability, torque documentation, incoming inspection processes, and traceability systems are captured in supplier profiles so you can assess process maturity before you share a BOM.
Simple kitting operations and complex multi-component precision assemblies are distinguished in the platform so you find assemblers whose experience level matches your product's requirements.
BOM complexity, work instruction availability, torque requirements, inspection steps, and volume go into one inquiry so assemblers can assess fit and respond with real capacity and lead time information.
TandemOne is always free for buyers to use.
OEMs and product companies who need a trusted assembly partner to convert manufactured components into a consistent, inspected sub-assembly or finished product, reducing internal headcount requirements, facility overhead, and production scheduling complexity.
