Major Process change in Zonhoven

April 2009

A growing demand for high-end panel radiators, has led Rettig Belgium in Zonhoven to search for a flexible and efficient process improvement.

These improvements have now been realised with the creation of a complete in-line process for flat front radiators through to the paint line. To achieve this, a multi-axis robot with a multi component gluing system has been developed.

The working process starts as follows: an operator places the front plate & radiators on a conveyor, which are then transported to the robot cell. Before the first staton is reached, the controller monitors whether a radiator is present. Then the robot applies the glue at a high flow rate with a triangular nozzle.

Line speed eclipses even the automotive sector.

This line speed is unique in comparison with similar applications in the automotive industry. Indeed, the maximum speed is about double of those used in the automotive industry.

As a result the average cycle time has been reduced with circa 50%. A second advantage is a significant reduction in material cost, which results from considerable less glue.

High repeatability and flexibility

These process improvements and investments have led to a combi-line of standard radiators & flat front radiators produced simultaneously and interchangeably, which appealing to a large Market. These ingredients are the tools for a higher efficiency and productivity. As a result, we can produce an average amount of 500 flat front units per shift.
