Sealingapplikation

100% protection – 0% corrosion and water incursion.

Before the painting operation, some areas, e.g. welding seams or raised seams on the doors or hoods of the car body, have to be sealed using viscous materials. This prevents water from penetrating into the car body and protects it from corrosion. With “Smart Seal,” Eisenmann offers you a complete robotic solution both for fine and rough seam sealing and for the application of underbody protection or sound deadening mats.

When plates are fitted together to form a car body, they have to be overlapped or joined. To prevent water incursion and resulting corrosion, either a fine or rough seam sealing operation is required. In addition to water protection, the visual (or cosmetic) aspect is also very important, especially with fine seam sealing. By using double-action cylinders and camera systems, Eisenmann provides maximum quality, high-precision metering and efficient application.

For reliable corrosion protection in the underbody and rocker panel area, Eisenmann offers you a dependable robotic application process. By implementing precise single and double piston metering systems, as well as compact, pressure-regulated solutions, this process allows for the efficient application of the large amounts of material typically required in this area. We also develop nozzles tailored to our customers’ specific applications and then put them into series production.

In order to effectively protect the car body from corrosion, the cavities are also coated with wax during production. With our “Smart Cavity Wax” technology, we’ve successfully brought the wax injection metering accuracy from an outflow rate of 2 - 15 ml per cavity down to approx. ± 0.1 ml. The result is a major reduction in material costs as compared to the systems commonly available on the market.

Using proven, solvent-free, “drop-stop” type waxes lets you minimize dripping, resulting in lower cleaning and disposal costs. By selectively heating the coated cavities with efficient IR radiation and doing away with active cooling, energy costs can be reduced by up to 50%. The use of an IR drying section also means there is no need for the usual convection dryer with cooling section, saving up to 65% more space.

For the automated processing of low-cost bitumen material, robots are used to insert stored sound deadening mats. Sound proofing is also available as a spray application system for all materials and designs with dosers and pressure controllers.

This process mainly uses proven standard components and does not rely on a conventional material supply unit, often reducing the investment total by up to 25%. And the fast commissioning times also contribute to the savings. The biggest cost savings of all, however, is the low cost of the sheets themselves as compared to liquid soundproofing material. This can yield a return on investment within one to two years.
