Where we help in automotive
Thermal and acoustic insulation
Lamination of thermally and acoustically insulating materials for floor panels, the engine compartment and the roof lining. Coating application of adhesive ensures full-surface adhesion with no air pockets.
Film lamination and surface finishing
Continuous coating application of adhesive onto films, textiles or non-woven fabrics – a precise layer thickness and a repeatable application even at high production speeds on calenders or roller lines.
Headlights and tail lights
Precise bead application of hot melt adhesive or sealant for a watertight and vibration-resistant assembly of the plastic and glass parts of light fittings.
Body seals and car body sealing
Application of butyl or polyurethane sealant from 20 l or 200 l drums for sealing the car body, grommets and panels. RobaDrum drum unloaders enable the processing of sealants with no interruption to production.
Fixing components and wiring harnesses
Dot or bead dosing of hot melt adhesive for fixing wiring, sensors, mounting badges, rear-view mirrors and other exterior and assembly parts directly on a robot or at an automated workstation. Volta electric heads enable intermittent application (stitching) with high repeatability.
What you're dealing with
- Automotive production allows no deviations – every part must have an identical adhesive application, otherwise there is a risk of complaints, recalls and supply outages. A reject rate from incorrect adhesive application is a direct loss.
- Production lines are fully automated and robotised – the application system must communicate with the PLC via Profibus or Profinet, synchronise the start and stop of application with the movement of the part and monitor adhesive consumption in real time.
- Different applications require different types of adhesive (PUR, PO/Metallocene, polyamide, sealants, butyl) as well as different types of application (bead, spray/swirl, coating) – designing a reliable platform for an entire plant is complex.
How Kaletech solves it
Robatech systems cover the entire spectrum of automotive applications: from dot dosing of adhesive at a robotic workstation through swirl spray onto shaped interior parts to coating application onto insulation materials. The choice of the right application head (SX Diamond, AX Diamond/Delta, Volta, Aero, FKV) and melter (Canduro 2, JumboFlex, RobaDrum) depends on the type of adhesive, the shape of the part and the line speed – which we always assess during the application analysis.
For reactive PUR adhesives we use Melt-on-Demand technology – only as much adhesive is melted as the line consumes at the given moment, and the PUR is not needlessly heat-stressed. The result is stable adhesive properties even during long production cycles and a lower risk of degradation. For high-capacity applications with drum sealants or butyl, RobaDrum drum unloaders ensure continuous operation even during a drum change.
The Robatech Control System (RCS) control platform enables connection to a higher-level PLC via Fieldbus (Profibus, Profinet) and monitors adhesive consumption in real time – too little application signals a risk of a poor bond, while increased consumption alerts you to a potential overflow or wear of a component.
How it works and what technology is used
Robatech technology for the automotive industry integrates a melter, a heated Performa hose and an application head into a controlled unit synchronised with the production line. The platform is designed for automation: starting, stopping and regulating the application respond to a signal from the PLC or robot, so the operators do not intervene in normal operation. The key is selecting the right combination for the specific application – the type of adhesive, the shape of the part, the line speed and the application method (dot/bead, spray, coating) define the configuration.
Selecting and preparing the adhesive
The type of adhesive determines the melter: reactive PUR hot melt is processed in a Canduro 2 or by RobaPUR using Melt-on-Demand technology (only the required amount is melted, the rest remains in a protective atmosphere). Thermoplastic hot melt granules (PO, EVA, PA) are melted by a JumboFlex or Vision. Sealants and butyl from drums are processed by RobaDrum 20 or RobaDrum 200 unloaders.
Transporting the adhesive to the application point
The heated Performa hose maintains a stable temperature and viscosity of the adhesive from the melter all the way to the application head – even over long distances or in a robotic arm. Stable pressure and temperature are a prerequisite for a repeatable application part after part.
Precise application with the application head
The choice of application head depends on the type of application: SX Diamond for fast dot or short bead applications, AX Diamond / Delta for robots and continuous bead application, Volta for electrically controlled intermittent dosing (stitching) with high repeatability, Aero heads for swirl spray onto irregular and shaped parts, FKV coating heads for coating application during lamination.
Integration with the line and process monitoring
The RCS control system communicates with a higher-level PLC via Profibus or Profinet and synchronises the start and end of application (cut-off) with the movement of the part. Integrated measurement of adhesive consumption monitors the process in real time – a deviation from the set limit triggers an alert before a reject piece is produced.

Frequently asked questions
Automotive production requires an identical application part after part – otherwise there is a risk of complaints and supply outages. Robatech systems allow you to set adhesive consumption limits per product: if the application is too small or too large, the RCS control system immediately alerts the operator or stops the line – before a reject piece goes to assembly.
