Machinery can be arranged in a number of ways in a foam line for refrigerators doors. Depending on the size of the doors, pouring style (open or closed mould) and volume of output that is needed from the factory. Bob Biondich, director of sales at Hennecke, outlines an innovative approach that maximises output and minimises footprint.
Domestic refrigerators are the last link in the cold chain, and they are one of the most logistically complex pieces of equipment in that chain.
While the number of cabinet sizes is fairly standardised within countries; the number of permutations of door components and internal arrangements for shelves is very large.
It is not always possible for a refrigerator maker to have a foaming line dedicated to foaming one type of refrigerator door, for example. While it may make sense from a production point of view to have large scale production of one model in a dedicated factory, the logistics of shipping empty refrigerators often means that smaller, flexible plants are more economically viable. Such plants may also have to produce several models of refrigerator, and this can lead to a situation where a plant has several foaming lines dedicated to an individual model or range of models.
Drum units are a good solution. They have good flexibility, and it is possible to change tooling if needed.
