Injection molding. Die casting. Mold making.
No sourcing fees. No middlemen. Startup-friendly minimum order quantities.
Aluminum (ADC12/A380) and zinc (Zamak 3/5) structural parts. Thin walls, tight tolerances, production-grade finishes.
Plastic parts for consumer electronics, appliances, IoT devices and consumer goods — from 160T to 400T+ presses.
In-house tooling in domestic and imported steels (P20, 718H, S136, ASSAB grades). You own your molds — in writing.
Not sure which process fits your part? The quarterly SunOn Cost Index publishes our real material and processing prices so you can see the economics yourself.
Step 1 — DFM review (free with every quote). Before we commit to tooling, I review your design for issues that would raise cost or hurt quality. This alone typically saves $10,000–80,000 in tooling modifications.
Step 2 — Tooling quote. A detailed quote with the steel grade named, cavity options, and surface finish grades — so you can compare it honestly against any other quote.
Step 3 — Tooling fabrication. The mold is yours: ownership is written into the contract, and it moves with you if you ever leave.
Step 4 — Sample approval. You approve first samples against the spec. We don't move to production until you confirm.
Step 5 — Production and shipping. Quality inspection before every shipment, with clear acceptance criteria agreed up front.
