What we help with — Injection Molding

Injection Molding sourcing for Ann Arbor programs

Custom plastic parts and enclosures, from prototype tooling through full production molds.

Our injection-molding bench covers everything from aluminum bridge tooling for 50-500 piece prototype runs to hardened steel production molds rated for 1M+ cycles. Resins span commodity polymers (ABS, PP, PE, PS), engineering grades (PC, PC/ABS, nylon 6/6, glass-filled nylon, POM/Delrin, PBT), high-temp materials (PEEK, PEI, PPS), and medical-grade USP Class VI resins. Process capabilities include 2-shot molding, insert molding for threaded inserts and electrical contacts, overmolding for soft-touch grips, and gas-assist. Tolerances follow DIN 16742 with critical-feature tolerances tightened on a part-by-part basis. Secondary processes — pad printing, laser marking, ultrasonic welding, sub-assembly — are coordinated as part of the program. We match each project to a tooling and molding source sized for the volume: a Tier-1 production molder for 100k+ annual parts costs more per cavity but pays back; a quick-turn prototype molder gets you to first-article in 2-3 weeks.

Why SmartFab

Why Ann Arbor teams source injection molding through SmartFab

One RFQ, one accountable partner

One injection molding RFQ from Ann Arbor returns one accountable manufacturing quote — sized for your volume, your certifications, and your lead time.

Supply chain headache, eliminated

We own sourcing, production, and follow-up on every Ann Arbor injection molding program so your team ships product instead of chasing shops.

Better supplier fit

Tooling investment scales with volume — prototype aluminum tools and production hardened-steel tools are different conversations and shouldn't go to the same shop. For Ann Arbor programs in autonomous vehicles, that means placing the build on a line with the right certifications and volume profile from day one.

Build approach

Build approach for Ann Arbor injection molding programs

When we route a injection molding RFQ for a Ann Arbor customer, we evaluate the build against facilities in our network on three axes: certifications (does it need ISO 13485 for medical or IATF 16949 for automotive?), volume (prototype, low-volume, production), and lead time. Ann Arbor's university spin-outs and AV testing hub need partners that bridge research-grade prototyping and automotive-grade production — our Midwest bench is structured to hand programs off between those two worlds cleanly.

For autonomous vehicles programs in Ann Arbor, we typically return one accountable manufacturing quote within 24–48 hours.
