The Bengaluru-based Valco Melton India, a part of the US-based Valco Melton – which manufactures dispensing machinery and quality assurance systems for adhesives – demonstrated its camera-based gluing and inspection as well as hot melt systems at the recently concluded IndiaCorr Expo 2022 held in Mumbai from 8 to 10 October 2022.

“Inspection system is all about ensuring if the adhesive is present on the box, and at the right place. This ensures no unglued boxes go to the customers or the market,” says Ravi Kiran, director, Valco Melton India.

Valco Melton’s GapChek camera vision inspection system detects gap defects. The GapCheck measures the lead and trail gaps and the skew of all boxes of a bundle. It then verifies them within the customer's requirements before they are delivered. Boxes with gaps out of tolerance are detected as faulty and highlighted on the screen for removal by BundleChek, immediately following the GapChek process.

The company also showed its regular hot melt adhesive dispensing system at the expo.

Exports of India-made hot melt machines up

Kiran says that the hot melt systems being made in India are being exported in big numbers to markets in Southeast Asia and the Middle East. Valco Melton India makes these machines at its Bengaluru plant.

“Hot melt machines that are being made at Bengaluru are exported to many countries. We are making close to 300 machines every year for the export markets in Southeast Asia and the Middle East,” he says.

Kiran says that the market for quality gluing machines is growing in India, and the trend has been especially pronounced after the outbreak of the Covid pandemic.

“Post-Covid, customers are going for high-speed line and for that, they require high-quality gluing and inspection systems to avoid bottlenecks,” he said.
