Frequently Asked Questions

  • What are the benefits of using custom aluminum and rubber extrusions for industrial applications?

    Choosing custom aluminum and rubber extrusions offers incredible durability, flexibility, and precision for demanding industrial applications. We specialize in both materials, providing custom-engineered profiles designed to withstand extreme environmental and physical conditions. Our aluminum extrusions offer excellent strength-to-weight ratios and natural corrosion resistance, which we can enhance with anodizing or powder coating. Meanwhile, our custom rubber extrusions provide superior sealing, insulation, and shock absorption. By utilizing our advanced fabrication and in-house tooling capabilities, we can deliver highly customized, complex shapes that fit perfectly into your final assemblies, saving you valuable assembly time.

  • How does in-house tooling development improve the injection molding process?

    Developing and building tooling in-house dramatically improves the quality, speed, and cost-efficiency of the injection molding process. We design and manufacture our own dies, molds, and specialized equipment internally, which gives us absolute control over the entire production process. This vertical integration allows our engineering team to quickly make adjustments, perform maintenance, and troubleshoot issues without relying on third-party toolmakers. As a result, we significantly accelerate your time to market while reducing overall tooling costs. Our facility operates fifteen injection molding machines, ensuring we can handle production runs of any scale with extreme precision.

Our partners value our ability to act as a strategic ally, helping them consolidate their supplier base, navigate supply chain complexities, and scale their production to support long-term business growth.

  • How do you ensure quality control across different material formulations and production methods?

    Quality is the foundation of our multi-generational family legacy. With over 150 years of combined industry experience and expertise in more than 500 resin formulations, we implement strict quality control protocols at every stage of production. By managing everything in-house—from initial CAD design and tooling development to final extrusion, machining, and finishing—we maintain total visibility over the manufacturing process.
