Advanced Plastic Sheet Extrusion Thickness Profiling Systems

The minimum measurable wall thickness depends on the specific polymer and application. Our M-Ray systems can accurately measure thickness ranging from sub-millimeter levels up to 30 centimeters for construction sheets. For standard extrusion applications with PE, PP, PMMA, or PC, we typically measure sheets from 0.5mm to several centimeters with exceptional precision.

Thickness tolerance varies by material type, production method, and industry standards. Our profiling systems enable manufacturers to achieve adjusted thickness values of approximately -5% compared to international thickness standards, significantly tighter than conventional measurement approaches. The multi-sensor platform detects localized variations, allowing you to maintain consistent tolerances across the entire sheet width.

Our M-Ray technology uses millimeter wave electromagnetic signals—similar to those in cell phones—to measure material thickness without physical contact. The waves penetrate the plastic material and return data that our advanced algorithms convert into precise thickness measurements. This approach works regardless of sheet color or temperature, even in harsh production environments near extrusion dies.

Yes, our systems include customized support for filling materials, which is particularly important for non-optical sheet applications. The M-Ray technology can see through opaque materials and characterize different compositions, making it suitable for measuring composite sheets, filled polymers, and reinforced materials that other optical or capacitive systems cannot handle.

Multi-sensor systems provide complete cross-machine direction coverage, detecting localized thickness variations that correspond to individual extrusion screws or die bolts. This comprehensive profiling enables targeted process adjustments rather than whole-line corrections, reducing material waste and improving overall sheet quality. Single-point systems can miss critical variations occurring between measurement positions.

Our systems operate at multi-kHz measurement rates, providing nearly instantaneous feedback for highly dynamic production environments. This rapid response enables closed-loop control systems that automatically adjust process parameters within seconds of detecting variations, minimizing scrap production during process upsets or material transitions.

We offer turnkey installations designed to minimize production downtime. Our team works closely with your operations to plan installation during scheduled maintenance windows when possible. The contactless nature of the measurement heads also means no physical modifications to your extrusion die or downstream equipment are required.

M-Ray technology features robust sensor head designs that withstand raw industrial environments with minimal maintenance. Unlike nuclear gauges, there are no radioactive source replacements or specialized disposal requirements. Regular maintenance typically involves calibration verification and software updates, which can often be performed remotely through our IoT connectivity platform.
