Continuous Blending in Exact, Precise Ratios.
Engineered as a part of Nu-Vu Conair’s TrueWeigh Gravimetric Extrusion Control System, the TrueWeigh Hopper measures the mass flow of material into the extrusion process and sends this loss-in-weight information to the TrueWeigh Controller. The controller then accurately monitors or adjusts the extruder screw and/or haul-off speed to maintain consistent yield control. This enables an operator to run a uniform product within the tightest tolerances at the lowest possible cost.
TrueWeigh can be used to control extruder rate by weight throughput, haul-off speed by length throughput, weight of product per running length, layer percentages by weight for co-extrusion, weight of product by area, average thickness of film, sheet, pipe, tube, wire and cable.
TrueWeigh Gravimetric Extrusion Control Systems are most often used with single screw, flood-fed extruders in mono-layer or co-extrusion applications. The most common applications are blown and cast film, sheet, extrusion coating and laminating, tube, pipe and profile, wire and cable jacketing, inventory control (material reporting).
