The TandemOne Platform

Find injection molding suppliers matched to your program

When buyers need to find injection molding suppliers for a new product launch, a re-source, or an overmolding application, TandemOne is the platform built for that search. We profile verified injection molders by press tonnage, material capability, tooling class, industry certifications, and secondary operations, so you can evaluate fit before you share a CAD file or commit to tooling. Send a Structured RFI on TandemOne and get qualified responses from molders who have run parts like yours, in your resin, at your volumes, to your quality standard.

Why TandemOne

Why buyers source injection molding on TandemOne

Tonnage and Tooling Transparency

TandemOne profiles molders by press range, tooling class (prototype vs. production), material capabilities, and secondary operations like overmolding and insert molding.

Industry Certification Filtering

Filter for ISO 9001, IATF 16949, ISO 13485 (medical), or FDA-registered facilities so you only see molders already qualified for your end market.

RFIs That Cover What Molders Need

Resin, annual volume, tolerance class, tooling ownership, and secondary operations go into one RFI. Molders can respond with real numbers from day one.

Send unlimited Structured RFIs to verified injection molders at no cost.
