The areas of adhesive application in the automotive industry are as versatile as the gluing technologies themselves. Gluing is increasingly replacing conventional car production techniques such as welding, riveting and screwing. It not only increases safety, but also simplifies many work processes and therefore improves economic efficiency.
Kaletech supplies powerful systems for the application of hot-melt, dispersion, and reactive adhesives for body and interior components, assembled parts, rear-view mirrors, roof linings, damping and thermal insulation parts, seat covers, headlamps and rear lamps.

A request from a leading car seat manufacturer involved the delivery of adhesive application technology capable of collaborating with an industrial robot in order to make the production automatic.
The application head applies a spray coating of hot-melt adhesive. Depending on the movement and position of the industrial robot, it deliberately omits the places above holes.
The result is a fully automated work station with the precise application of the desired layer of adhesive in the desired locations.
A leading automotive upholstery manufacturer contacted Kaletech with a request for automated measurement of adhesive application for upholstery for car door panels. The customer's main requirement was to keep the adhesive deposit between two layers of upholstery materials constant.
The solution consisted of the use of a travelling thermal camera which scans and measures the adhesive coating thickness. It evaluates and gives a warning if the layer breaches the limits or indicates future irregularities and produces a report for quality control. The device has the possibility to change the gluing parameters on-line.
The new solution is more efficient from the point of view of adhesive consumption and thanks to the automated measurement system, the quality of uniformity of its application is monitored continuously. Our customer saves €27,000 per year on rejects and €8,500 on adhesive consumption.
The customer's requirement was to deliver gluing technology which would allow them to change the parameters and gluing width according to the needs of individual products.
The solution was to design a unique application head with 78 modules and a blade that allows intermittent adhesive application.
The customer can set the parameters and width of gluing for individual products without stopping production for complicated adjustment of the machine.
