HELLA - A shining example of industrial adhesion

Adhesion of headlamps for the automotive industry

It was with headlamps that the family company HELLA made its name. In addition to halogen headlamps as standard basis technology, it has produced xenon headlamps for over 20 years, and LED systems for a few years. At the same time, the attractive style of the HELLA headlamps is compatible with the design of the vehicle. This technical and stylistic variety requires optimal adhesion during production, which is ensured by WAGNER Reinhardt-Technik’s dosing system.

Fast & efficient production thanks to long component lifespans, interruption-free operation, simple touch control and low cycle times
Service-friendly system design & low maintenance effort

The customer´s challenge

Adhesion is a key factor in the manufacturing process of automotive headlamps. The adhesive used for manufacturing headlamps must have a very high level of impermeability. The complex and sensitive light elements should be protected throughout their lifespans against the penetration of sprayed water and splashes. To ensure that HELLA's high quality standards are met, dosing precision, uniformity and a constant melting capacity must be guaranteed.

Our solution

The PUR dosing system „RT Warm Melt 800“ by WAGNER Reinhardt-Technik, both available in a single and tandem version, has been specially developed for the processing of moisture-curing PUR melt adhesives with high viscosities. The unique heating plate design and the hydraulic head piston dosing system generate excellent melting and conveying power. The systems impress with long component lifespans, interruption-free operation, and simple control by means of a touch panel.
