In the world of custom injection molding, size – and strength matters. At Pyramid Molding Group, in Rockford, IL our 1,000-ton injection molding presses give manufacturers a rare and valuable advantage: the ability to mold large plastic parts with structural integrity, speed, and U.S.-based reliability.

Why Large-Tonnage, Domestic Injection Molding Matters

Many injection molding companies in the U.S. operate presses between 100 and 350 tons. But for OEMs producing structural parts or multi-cavity components, that’s not always enough. Projects that involve high-performance materials, thick walls, or tight tolerances often demand something more.

That’s where our 1,000-ton presses comes in.

At Pyramid Molding Group, we’ve invested in this press to help our customers:

• Mold oversized, structural plastic parts with high precision
• Handle multi-cavity tooling without compromising cycle time or quality
• Mold with engineering-grade resins like glass-filled nylon or polycarbonate
• Keep production onshore to reduce risk, delays, and freight costs

Built for Complex, Large-Scale Projects

Our 1,000-ton press isn’t just large-it’s backed by decades of experience in:

• Custom in-house mold design and build for complex parts
• Engineering support from concept to production
• Insert molding and overmolding
• Final assembly, packaging, and fulfillment
• From appliance bases and industrial housings to load-bearing brackets and support frames, we specialize in molding the types of parts that other shops just can’t handle.

Need tooling, too? Our in-house tooling division provides precision-built molds optimized for large-tonnage production.
