Lohia Mechatronik showcased its motor-controlled automatic die system, online thickness measurement systems, and AI-powered defect inspection systems at PlastIndia 2026 in Delhi. The company, along with its international arm SBI Mechatronic Austria, specializes in high-precision online thickness measurement gauges for extruded plastic sheets and films, integrated with extrusion die bolt control systems. With manufacturing facilities in Pune and Austria, the company serves a global customer base with precision-engineered solutions.
One of the key highlights at the show was the company’s motorized bolt controlling system for flat extrusion, designed to enable real-time thickness profile correction. Explaining the innovation, Siddharth Lohia, CEO of Lohia Mechatronik, said each die bolt in the system is individually motorized and dynamically adjusted based on live thickness data. “While thermal bolts have traditionally been the industry standard, our motorized system offers significantly faster response, higher precision, and true closed-loop control,” he noted. This system enables manufacturers to achieve uniform thickness profiles, reduced material wastage, and improved product consistency, even at high production speeds.
Another attraction was the machine vision-based defect inspection system. The system is engineered to detect a wide range of defects across diverse applications, including BOPP/BOPET, CPP, metallized films, FIBC fabrics, and other sheets and films. Leveraging AI, the system can intelligently distinguish between normal material variations and actual defects, significantly reducing false positives while enhancing detection accuracy and reliability. “The entire defect inspection process fundamentally runs on AI, understanding what a defect is and what is not is only possible through AI,” Lohia explained.
The company also demonstrated its online thickness measurement systems, capable of delivering high-resolution, edge-to-edge thickness mapping across the film or sheet width. These systems provide real-time feedback to the die control system, enabling a fully integrated closed-loop solution combining measurement and control.
Lohia expressed strong optimism about the Indian plastics sector, attributing it to a combination of rising population and increasing per capita plastic consumption. “This double-engine growth will dramatically expand the industry,” he said, adding that responsible usage of plastics remains crucial.
He said automation remains central to Lohia Mechatronik’s philosophy. According to Lohia, the company is committed to reducing manual intervention, minimizing dependency on skilled labor, and enhancing operational efficiency through automation and AI.
Looking ahead, the company plans to strengthen further its capabilities in die automation and expand the technological scope of its sensor-based thickness measurement systems. “These are the two areas we are focusing on for future innovation,” Lohia concluded.
