Over 55 years of custom thermoplastic fabrication expertise
Established in 1970, Harrison Machine & Plastic Corporation is the "Total Source" for custom fabricated plastic tanks. Our skilled fabricators work directly from customer prints or sketches to produce tanks that fit your exact process requirements. Whether you need a simple drip containment pan or a complex multi-compartment process tank, Harrison delivers quality, precision, and corrosion resistance in every weld. All tanks are fabricated in our Garrettsville, Ohio facility using premium thermoplastic materials selected for your specific chemical environment.
Every configuration built to your specifications
Flat-sided tanks ideal for maximizing floor space and easy integration into process lines. Available in any dimensions, with or without covers, fittings, and internal baffles.
Vertical or horizontal cylindrical tanks offering superior structural strength and even pressure distribution. Available with flat, cone, or domed bottoms.
Secondary containment pans fabricated to fit under valves, pumps, and process equipment. Custom dimensions to match your footprint and chemical exposure requirements.
Heavy-duty tanks for chemical processing, electroplating, etching, and treatment applications. Designed with appropriate wall thickness, reinforcing ribs, and all required process connections.
Thermoplastic liners installed inside existing concrete or metal tanks to provide chemical resistance and extend service life without full tank replacement.
Multi-compartment tanks, tanks with integral sumps, overflow weirs, heating coil pockets, agitator mounts, and any other custom feature your process demands.
Select the right thermoplastic for your chemical environment and temperature requirements
Advanced thermoplastic fabrication — the Harrison "Total Source" difference
Send us your engineering drawings or a hand sketch — our experienced fabricators will produce your tank to exact specifications. No standard sizes to work around.
Precision CNC machining for nozzle penetrations, flange faces, mounting pads, and custom fittings. Tight tolerances achieved on all machined surfaces.
Structural hot-air and extrusion welding techniques produce strong, leak-tight seams. Multiple weld passes ensure full fusion and long service life.
All required nozzles, flanged outlets, drain connections, overflow weirs, vent ports, and inspection hatches fabricated and installed at the factory.
Sheet bending, heat forming, and rolling to produce curved panels, cone bottoms, domed heads, and complex three-dimensional shapes from flat sheet stock.
Every tank is thoroughly inspected for weld integrity, dimensional accuracy, and proper fit-up of all connections before shipment from our Ohio facility.
