From prototype to full production — every service you need, delivered in-house by a team that's been doing this for over 40 years.
Our core service and our specialty for over 40 years. Whether you need 500 precision components or 5 million, we deliver molded plastic parts that meet your exact dimensional, material, and quality requirements.
Our Toyo injection presses — ranging from 28 to 300 tons — give us the flexibility to run small, precise parts and large structural components with equal accuracy. Every job runs with documented process parameters, in-process inspection, and final quality sign-off.
The fastest path from concept to market is having one partner who can take you the entire distance. We build your prototype tool, produce first-article samples, refine the design, and then scale directly into production — no re-quoting, no handoffs, no delays.
Prototype aluminum molds can be completed in as little as 3–4 weeks. When you're ready to scale, we either convert the prototype tool or build a production steel tool — all with the same engineering team that started the project.
Our in-house toolroom designs and fabricates both prototype aluminum and production steel injection molds. Keeping toolmaking in-house means tighter control over quality, faster turnaround, and lower cost compared to outsourced tooling.
We build single-cavity, multi-cavity, and family molds in aluminum (for prototyping and short runs) and hardened tool steels (P20, H13) for high-volume production. We also offer mold repair, refurbishment, and storage for your existing tooling.
Great parts start with great design. Our engineering team works with you from the earliest stages — whether you have a napkin sketch, a physical sample, or a complete 3D CAD model — to optimize your part for manufacturability, function, and cost.
Every quote includes a free DFM review. For new designs, we provide full CAD modeling, mold flow simulation, wall thickness analysis, gate location optimization, and material selection guidance before any tooling is built.
Many machined, cast, or stamped metal parts can be replaced with engineered thermoplastic equivalents — with equal or better mechanical performance, at a fraction of the cost and weight. BrokerMFG specializes in this conversion process.
Our engineers evaluate your metal part for conversion feasibility, select the appropriate engineering resin (often glass-filled nylon or PC for structural applications), optimize the geometry for plastic behavior, and validate the final design before tooling.
Typical Results from Metal-to-Plastic Conversion:
Not every project needs a million-piece run. Our short-run molding service is designed for customers who need production-quality parts in small batches — for market testing, bridge supply while permanent tooling is built, or specialty programs with inherently low volumes.
Unlike some suppliers who treat low-volume orders as low priority, we treat every job the same. You get the same materials, the same presses, and the same quality inspection — regardless of quantity.
