The Ljunghäll Group (a subsidiary of the Gnutti Carlo Group) is located in Södra Vi, Sweden and is one of the largest companies in the field of aluminum die casting. Ljunghäll has 4 factories around the world, producing parts and components for automobile manufacturing.

For a new project-the machining of gearbox housings, camshaft housings and so-called flywheel housings, Ljunghäll is looking for an experienced partner to finish the casting and found a partner in Mössner.

August Mössner GmbH Co KG is located in Eschach, southern Germany, and reviewed more than 30 years of expertise in the HPDC field of precision machining castings.

Eric Müller, Chief Technology Officer of Ljunghäll, has established a long-term partnership with Mössner. Their comprehensive expertise and flexible casting finishing line system concept give them confidence.

The high requirements for quality and reliability perfectly combine the common values ​​of Ljunghäll Light Metalls Division and Mössner.

The challenge of machining various large parts lies in their geometry, especially their weight. In particular, the inner side of the workpiece that is difficult to reach requires precise deburring.

In addition to precise and efficient deburring technology, the production line is characterized by its modularity and flexibility.

The number of units required will increase within a few years as planned. In order not to make the total investment at the beginning of production, it is allocated according to the required factory capacity.

Therefore, additional deburring robots can be used to supplement the processing line in the further construction phase. This reduces the cycle time, thereby increasing the output of the workpiece.

This flexibility was the main factor in Ljunghäll's decision to cooperate with Mössner.

There are seven different workpieces in the Mössner system, without any manual setup process. The image processing system detects the corresponding workpiece type. Based on this information, the robot will automatically switch to the corresponding gripping system.

The castings are fed into the system via a conveyor belt. The vision system detects the position of the workpiece and transmits this data to the robot.

The gearbox shell is picked up by the robot's gripper system. Then the robot moves to the deburring spindle. Here, a combination of a compressed air-driven spindle and a mature Mössner machining spindle is used.

Workpiece guide rails can be quickly changed to different processing stations.

In addition to processing, the robot also takes over handling tasks when loading and unloading the shot blasting machine.

To ensure the traceability of the castings, the DMC code is applied by the laser marking machine in the next step.

The processed and marked workpieces are transported out of the system via a conveyor belt to reach further process steps.

Mössner develops and builds special solutions in the fields of mechanical engineering, automation technology and robotics. One of the focuses of this product portfolio is turnkey casting and finishing lines and reliable automated factory technology. This includes the processes from core processing, casting machine automation, cooling and industrial marking to coring, sawing, milling and deburring, as well as all the necessary sub-processes of casting production.

Mössner's expertise comes from the installation and commissioning of various automation solutions for customers in the global foundry and automotive industries.
