PVC cones for protein skimmers, architectural and trade show displays, light diffusers, funnels, tanks, hoods, shrouds, duct transitions and many other applications.
We make clear and opaque cones in any thermo-formable material. The size is limited only by our shop door.
We fabricate clear cones primarily from acrylic, clear PVC, LEXAN® (polycarbonate), and PETG and we fabricate opaque cones in PVC, polypropylene, polyethylene ABS, Kynar® (PVDF) and any other plastics that can be thermoformed.
The cones can be symmetrical, or offset. If you can draw it, we can probably make it.

PVC Cone Examples
We make cones for industrial customers with materials selected to be compatible with your environment. These cones are formed at any angle and then seamed. We mount them to your design. We mount flanges, bases , gussets and various threaded and flanged fittings to the cones per your design.
Cones for Protein Skimmers
Polyfab offers 3 series of cones, primarily to meet the needs of protein skimmer fabricators. The cones are offered in cast acrylic and clear PVC in thicknesses of 1/8 inch (3 mm), 3/16 inch (5 mm), and 1/4 inch (6 mm).
Cones of any other dimensions can be fabricated, but tooling charges are frequently required. The seams in acrylic cones are cemented and the seams in clear PVC are hot air welded.
