Wheels

Eisenmann is the world market leader in this area with over 130 systems for wheel painting. Every fourth automobile wheel is treated in Eisenmann plants.

PRE Treatment

Eisenmann builds systems for chamber pre-treatment as well as for continuous pre-treatment. Particular attention is paid to optimizing water consumption. This significantly reduces both the costs for fresh water and wastewater treatment.

A perfect primer is the basis for a harmonious paint structure. Cathodic dip painting (KTL) is a particularly economical option for steel wheels in particular. Eisenmann has the ideal combination of process and conveyor technology in its range for each concept, each integrated into the ideal logistics concept. The entire process-related peripheral equipment comes from a single source and is also individually tailored to customer needs. This makes energy-saving and resource-saving systems possible.

Conveyor Systems

The circular conveyor is a closed, three-dimensional conveyor system and can be used up to ambient temperatures of 250°C. With the circular conveyor (continuous conveyor), the weight of the components hangs directly on the chain. It can be used variably and can be adapted to changed production conditions easily and cost-effectively.
Our circular conveyor is available for operation under continuous motion as well as for intermittent use, it is robust and distinguishes itself by its high reliability, even in sometimes quite complex and thus difficult areas of application.

With the variable spindle conveyor system from Eisenmann, vehicle wheels in particular are conveyed in a horizontal position through successive treatment stations of a paint shop. In these, the vehicle wheels are then provided with a surface coating in several treatment steps.

Due to their high flexibility in terms of speed and media, Power & Free systems link the most diverse production sites and processes. This minimises the number of workpiece transfers and system changes. This applies to the Overhead Power & Free system as well as to the Inverted Power & Free conveyor with its ability to selectively feed and pick up, store, sort and dose workpieces. In addition, these systems can continuously convey the workpieces. They thus enable an extremely energy-efficient, economical and flexible direct connection to the upstream and downstream zones as well as a complete in-house material flow.

The inverted Power & Free system SG 665 has all the features of the Power & Free system SG 666.
SG 666 with the advantage that it runs on the floor underneath the workpieces. It can be combined with a wide variety of trolley hoists that are specially developed for the respective applications. For example, trolley hoists for wheel systems are available with a rotating crossbeam, so that short stacking distances are created when 2 wheels are picked up per trolley hoist with the crossbeam turned 90°. Efficient, flexible, energy- and space-saving!

Eisenmann turning stations for powder and wet coating have the task of turning the turning spindles of the coating conveyors and thus the wheels in the coating area. Forwards and backwards rotation is possible.
The different speeds are achieved by frequency-controlled drives.

In the Eisenmann spindle cleaning cabin, the wheel mounting spindles (in throughfeed or cycle operation) are cleaned of loosely adhering coating material after powder coating by rotating roller brushes in the interior and blown off.
Clean spindles ensure absolutely paint-free hub supports on the wheels.

Die Nabenflanschreinigung dient der automatischen Beseitigung von lose anhaftendem Beschichtungsmaterial an den Drehspindeln und Radaufnahmen nach der Pulverbeschichtung von Fahrzeugrädern.
Die Naben- und Flanschflächen werden in einem Zwischenschritt der Übersetzeinrichtung in einer Reinigungsstation gereinigt und nehmen danach wieder
vorbehandelte Räder auf.

Paint Seperation

With the E-Cube, Eisenmann has developed an extremely successful and popular separation system. Thanks to its sophisticated filter technology, the E-Cube does not require any chemicals, water or other additives (such as binding agents). This saves resources and simplifies waste disposal. The energy- and resource-saving E-Cube can be used in the entire wet painting process – i.e. in the area of wheel, plastic as well as general metal painting. The system consists of 60 to 80 percent recycled material, is easy to handle and can be operated by anyone.

Eisenmann offers two separation processes in the field of wet scrubbing: Compact crossflow venturi and double crossflow venturi. They can handle different paint systems in a wide range of quantities and adapted coagulations. In automatic coating systems, most of the air that is extracted and cleaned of paint mist is returned to the booth (recirculation mode). In order not to exceed the permissible solvent concentration in the spray booth, a partial flow of the recirculated air volume is discharged as exhaust air.

Dryer

Convection or circulating air drying is mainly used for paint curing. However, it is also used for drying adhesives, gels or adhesive water. In addition, these dryers are used for preheating before coating. Eisenmann’s dryers are able to achieve optimum efficiency through targeted airflow. In addition, they can be divided into several heating and holding zones.
Rapid heating and uniform temperature distribution can be individually adapted to the workpiece geometry. The focus is on short process times and high throughput rates with consistently high quality.

Automatisierte Digitalisierung

Automobile manufacturers all over the world demand paint-free functional surfaces of light alloy wheels. This requires masking of the corresponding surfaces. Eisenmann has developed an automated masking system with an image recognition system that reliably handles the processing of large quantities and enables sustainable increases in production. The bunkers of the Eisenmann masking station can hold up to 10,000 elements, which are automatically fed in by a robot in the correct position and separated. Using a vacuum suction cup, the robot picks up the masking parts and places the balls and plugs in the screw holes of the individual wheel types.

The wheel gripper developed by Eisenmann facilitates the transfer of wheels between the various process steps and contributes to automation in wheel machining. It features significant weight savings as well as a reduction in gripping time of up to 30 percent. In addition, lower energy costs are achieved. The wheel gripper impresses with its flexibility and optimum availability. The proportional technology ensures maximum precision and short cycle times.

Neben neuen Radkonzepten für E-Mobilitätsräder dominieren im Bereich der Aluminiumräderentwicklung Big Data-Themen wie Radkennzeichnung und Einzelradverfolgung. Dadurch werden Prozesse nachverfolgbar, transparent und langfristig besser optimierbar.
