What we help with — Injection Molding

Injection Molding sourcing for Long Island 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 Long Island teams source injection molding through SmartFab

Multiple qualified sources, one RFQ

One injection molding RFQ from Long Island surfaces real quote comparisons from multiple shops — sized for your volume, your certifications, and your lead time.

Supply chain headache, eliminated

We absorb the sourcing, vetting, and follow-up on every Long Island injection molding program so your team stops chasing suppliers and starts shipping product.

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 Long Island programs in aerospace & satellite, that means routing to a shop with the right certifications and volume profile from day one.

Sourcing approach

Sourcing approach for Long Island injection molding programs

When we route a injection molding RFQ for a Long Island customer, we evaluate the project against partners on three axes: certifications (does it need ISO 13485 for medical or IATF 16949 for automotive?), volume (prototype, low-volume, production), and lead time. Long Island's legacy aerospace base — Northrop heritage, BAE, Telephonics — runs on AS9100 and IPC Class 3 workmanship, and our Northeast bench is curated around shops that hold those standards across PCBA, harness, and machining.

For aerospace & satellite programs in Long Island, we typically shortlist 2–3 partners and surface real quote comparisons within 24–48 hours.
