Aplicación: Spray tyre mounting agents in a controlled manner during tyre fitting

In brief

Tyre mounting fluids or suitable lubricants reduce friction between the tyre bead and the rim and support a safe, uniform fit. The application should wet the required areas without spreading the medium uncontrollably within the component or workplace.

De qué se trata esta aplicación

The right solution starts with the entire process rather than an individual gun. Spray pattern, nozzle design, material pressure, delivery, component movement and cleaning must be considered together to keep the application stable and repeatable.

Purpose and benefits of the coating

The application mainly concerns tyre beads, rim flanges and defined contact areas of wheel-and-tyre assemblies. The required effect is achieved only when the coating material, substrate, layer thickness and subsequent drying or curing are compatible. The spray process must therefore be matched to the specific material system and actual production conditions.

Alongside surface quality, material consumption, cleaning effort, system availability and reliable repeatability also matter. A sound technical solution therefore combines controlled atomisation with a stable material supply that is easy to regulate.

What matters with the application

Even small fluctuations in material pressure, viscosity, distance or movement control can change the coating visibly or functionally. Typical requirements include:

uniform wetting around the entire surface
targeted application to narrow contact zones
Avoiding drops and excessive transport
Adaptation to different tyre sizes
Short cycle times in assembly lines
good cleaning and material compatibility

Apply mounting agent to the tyre bead and rim in a controlled manner

During tyre mounting, suitable mounting pastes or liquid mounting agents reduce friction and help fit the tyre onto the rim. Application should completely wet the bead and relevant contact areas without unnecessarily reaching visible surfaces, the brake or the floor.

The medium must be compatible with tyres, rims and later operation. Spray technology is adapted to viscosity, component size and cycle time.

Uniform wetting of the tyre bead
small and reproducible quantity of material
clean limitation of the spraying area
no after-dripping at the workplace
easy cleaning during product changes

Spraying technology and material supply from Krautzberger

Krautzberger treats application and material supply as a connected system. Depending on the task, manual and automatic spray guns, suitable air and material nozzles, material pressure tanks, diaphragm pumps, pump and lifting stations, and material pressure regulators can be combined.

In automated processes, spray guns can be integrated into mounts, lifting devices, axes or robots. Material changeover valves and flushing equipment support applications with several colours or media. The specific selection depends on viscosity, solids content, application quantity, cycle time and component geometry.

For fine surface finishes, various XLINE nozzle combinations and spray patterns are available. With highly viscous, abrasive or sedimenting media, sufficiently large flow cross-sections, suitable material combinations, agitators and pressure-stable delivery become more important.

The focus is on compact automatic spray guns, round jet nozzles, circularly arranged spray positions, material pressure vessels or pumps and precise pressure regulators. The technically and economically suitable combination is selected for the specific medium, components and required production output.

Typical applications

The application is used in different industries and component groups. Typical examples are:

Car and commercial vehicle tyres
Industrial and special tyres
automated wheel assembly lines
Manual mounting positions
pre-wetting of the tyre bead or rim area
Process support with varying dimensions

Process integration and automation

The wheel or tire can be rotated during the application. Spray release, quantity and position are adjusted to dimension and cycle time.

In addition, component feed, extraction or ventilation, cleaning, media change and accessibility for maintenance work must be taken into account during the system integration. This keeps the process stable not only in the pattern run, but also in everyday production.

Process design at the Krautzberger technical centre

Liquid media and coating materials with similar names can differ considerably in viscosity, solids content, solvent base, wetting and drying. A reliable choice of spray gun, nozzle and material supply should therefore be made using the original material and a representative component.

Wetting, application, assembly force and residues are evaluated with original tyres, rims and mounting agents.

On this basis, the spray pattern, material quantity, pressure, distance, movement and cleaning sequence can be defined. The result is an application solution suited to the medium, the geometry and the intended production process.
