Custom Molding Prototype Mold Making Design Engineering Metal Replacement Short-Run

Custom Thermoplastic Injection Molding

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.

  • Single & multi-cavity molds
  • Complex geometry parts
  • Tight dimensional tolerances
  • Any production volume
  • Engineering & commodity resins
  • 100% defect-free guarantee

Prototype to Production

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.

  • Aluminum prototype tools in 3–4 weeks
  • Free DFM review before tooling
  • Production-quality parts from day one
  • Seamless scale-up to full production volume

Mold & Tool Making

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.

  • Aluminum & P20 / H13 steel molds
  • Single, multi-cavity & family molds
  • Mold repair & refurbishment
  • Secure on-site tool storage program

Design Engineering & DFM

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.

  • Free DFM with every quote
  • CAD design from sketch or sample
  • Mold flow simulation analysis
  • Material selection & performance guidance

Metal-to-Plastic Replacement

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:

30–60%

Short-Run & Bridge Molding

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.

  • No minimum order quantity
  • Production-grade tooling & materials
  • Ideal for market testing & bridge supply
  • Same quality standards as full production
