Staroba Plastics

Staroba Plastics, Inc. is a vertically integrated plastics manufacturer based in Holland, NY

Staroba Plastics, Inc. is a vertically integrated plastics manufacturer based in Holland, NY, providing injection molding, custom plastic compounding, recycled-material processing, product manufacturing, and related production capabilities. Established in 1969, Staroba serves the construction, automotive, consumer products, and other manufacturing markets from its approximately 180,000-square-foot Western New York facility.

Staroba operates more than 32 injection molding presses ranging from 150 to 1,000 tons, allowing the company to support a broad range of molded component sizes, materials, and production volumes. Its molding operations incorporate material-handling systems, automation, and auxiliary equipment to support efficient, repeatable production.

Injection molding material experience includes TPO, ABS, polycarbonate, polypropylene (PP), thermoplastic rubber (TPR), plastic composites, HDPE, LLDPE, and proprietary Starloy materials. Staroba's combination of molding capacity and material expertise makes the company a potential manufacturing partner for OEMs and businesses requiring production plastic components or products.

Staroba also offers custom plastic compounding capabilities using three single-screw extrusion lines and two mixing lines. These systems can process approximately 600 to 3,800 pounds per hour and support both batch and continuous mixture streams.

Custom compounding services can modify existing plastics with additional materials or convert incoming material into pelletized feedstock suitable for injection molding. Staroba can also help manufacturers incorporate recycled material into their material streams, creating opportunities for companies seeking more sustainable manufacturing processes, recycled-content products, or alternative material formulations.

A major differentiator is Starloy, Staroba's proprietary thermoplastic material developed from recycled vulcanized rubber scrap and plastic scrap. Starloy can be used as a replacement thermoplastic elastomer and can be modified to meet specific application requirements. The material has been used for decades in manufactured products and supports Staroba's focus on diverting scrap materials from landfills and converting them into useful manufactured goods.

Staroba is also the exclusive manufacturer and distributor of EcoStar synthetic roofing products. EcoStar products use recycled plastic and rubber to create sustainable alternatives to traditional slate and other steep-slope roofing materials, demonstrating Staroba's capabilities in recycled-material formulation, high-volume molding, finished-product manufacturing, and commercialization.

Staroba's vertically integrated operation brings manufacturing, material processing, distribution, and marketing together within its Holland facility. This structure allows the company to support projects requiring more than standalone injection molding, particularly when material development, recycled content, custom compounding, molding, and finished-product manufacturing need to work together.
