Coating & Laminating
Adhesive dispensing solutions for coating and laminating
H
eadquartered in Cincinnati, OH (USA), Valco Melton is a leading supplier of adhesive dispensing and quality assurance systems. We specialize in the design and manufacture of technologies that apply, monitor, and verify cold glue and hot melt adhesives for a variety of manufacturing processes. Since 1952, the company has grown to become an international company with design and manufacturing facilities across America, Europe and Asia, as well as developing an extensive global sales and support network. The company holds a strong presence in several industries, including the corrugated, folding carton , envelope, bag, print finishing, packaging, woodworking, and the nonwoven industries.
Regarding the Coating and Laminating industrial hot melt applications, few companies can boast the knowledge, trust, and experience that Valco Melton has acquired by working on special projects throughout the years. We maintain a specialized coating team that is fully dedicated to R&D, design, testing, manufacturing, installation, and post-sales support of dispensing equipment for the coating and converting industries. By evaluating the specifications in each customer project, our team develops a tailored solution that will seamlessly integrate into the customer’s production process.
Over the years, Valco Melton has developed a complete range of contact and non-contact coating and laminating system solutions for multiple applications, such as label stock, inline label and linerless label manufacturing, flexible packaging, and technical, medical, and packing tape manufacturing. A relevant aspect of Valco
Melton’s solutions is that they cover the complete adhesive dispensing process – from the pre- melting to the application and quality assurance. Specific solutions include a selection of applicators to cover any coating and laminating requirement. From standard applicators with multiple adhesive inputs to metering systems for improved adhesive distribution across the substrate width. Also worth mentioning, our versatile applicators with interchangeable blades for rotating bar, continuous or intermittent applications, and our sophisticated dies that feature an automatic width adjustment system through a stepper motor.
In regard to melting needs, Valco Melton offers a variety of pre-melters, including pail or drum unloaders, as well as extruders for adhesives delivered in granulate format. Buffer tanks, and melters with different tank capacities are available to cover all melting needs.
We design and manufacture complete coating systems that can be integrated into any new or existing line. Two substantial side plates house the extrusion die, die mount, precision EPDM rubber or chrome coating roller, motorized back up roll and any necessary path and nip rolls to suit each individual project specification. Our selection of accessories include mounting bracket options to guarantee a correct adhesive penetration and coat-weight, flow meters for a constant monitoring of the adhesive dispensed, static mixers, and remote pumping stations to increase the number of dosing points with improved consistency and pattern stability. Additionally, our Smart Control allows the operator to visualize and manage the complete hot melt dispensing system (drum unloaders,
melters, applicators, and accessories). Incorporating quality inspection systems helps identify production defects as they occur. This allows to take immediate corrective actions, reducing material waste, product loss, and overall production costs. Our quality inspection equipment includes grammage controls and vision inspection systems.
By constantly measuring the adhesive grammage applied throughout the whole substrate width, our grammage controls detect excess or lack of adhesive, which would result in a defective product. Immediate corrective measures can be taken manually, or automatically when working with pumping stations in close loop. Vision inspection systems can detect application defects that would be hard to spot on certain final products, such as tape or labelstock rolls, and can affect the product quality. It’s the case of streak marks or scratches on the adhesive that might be caused by small contaminants in the nozzle, charred adhesive trapped in the application, or excess or lack of glue during machine stops and restarts.
Committed to sustainability, Valco Melton has been re-thinking traditional adhesive dispensing processes for the different industries. Working in close relationship with other industry suppliers, we have defined the basis of our current and future developments, focusing on adhesive and material usage reduction, energy efficiency, waste reduction throughout the complete production process, and quality assurance systems that improve manufacturers control over their production.
