Product Line: Sizing

ESI manufactures a wide variety of sizing tanks and tables for plastic and composite sizing. ESI's Vacuum Tables are designed for the processing of plastic profiles in a variety of rigid materials. Tables can be supplied in a variety of widths and lengths with different manifold, pump and cooling options. ESI's Vacuum Calibration Sizing Tanks are designed for the processing of plastic profiles in a variety of rigid and flexible materials. Tanks can be supplied in a variety of cross sections and lengths with different manifold and cooling options. ESI also offers hot water annealing of the front section to minimize bow in profiles with uneven thicknesses, allowing the product temperature to drop below the glass transition point before cooling with chilled water. This greatly reduces bow and camber on many profiles. ESI's Full Vacuum Sizing Tanks are designed for the processing of tubing and small pipe in a variety of rigid and flexible materials. A variety of different cross sections and tank lengths are available. All tanks are manufactured of heavy gauge stainless steel and incorporate non-corrosive internal components.
