Bytewise Measurement Systems in
Extruding cellular PVC presents a challenge: to dimensionally control the product after the chemical reaction of the blowing agent, according to Bytewise, a maker of on-line measurement systems. The process requires continuous on-line monitoring for size and shape, especially for features that affect fit and alignment, like tongue-and-groove dimensions, the firm said.
Profile360 uses a laser profile sensor, which digitizes the profile. Once digitized, virtual software calipers are applied to capture key dimensions, which are displayed for the operator. Bytewise compares it to a real-time optical comparator.
When extrusion goes out of specification, the operator is alerted immediately.
