Foundry

Workshop for the preparation, maintenance, quality control and development of the tools necessary in all the production workshops. With several hundred references available, this is where our products come to life.

Moulding is the workshop where the moulds for moulding parts are created. The moulds are made by two moulding machines:

• A moulding machine to make the lower mould.
• A moulding machine to make the upper mould.

Avec un temps de cycle de moins de 20 secondes par moule, l’atelier de moulage à la capacité de fabriquer environ 5 000 moules par jour. La taille des châssis permet de fabriquer plusieurs pièces par moule. Après avoir donné la forme de la pièce à produire au sable à vert, le châssis est transporté sur une ligne de remmoulage pour permettre la pose de noyaux.

Core-making is the workshop where the cores are made by two machines called coremakers. The cores correspond to the hollow parts of the finished part. They are made with sand to which binders are added to obtain the desired mechanical resistance. This resistance is obtained by a catalyzing gas. The manufacture of more than 500,000 cores per year is managed by an independent foundry team. The cores are soaked to form a protective layer and then dried in an oven. A storage capacity of more than 6,000 cores assures we have a 2 to 3 day buffer for moulding and core-making.

At the finishing stage more than 4,000 parts produced daily are freed from their moulding sand and gates. The frames are drained on shakers to separate the sand from the parts. Vibrating conveyors are used for this operation.

Using a manipulator arm, the parts are hung on an overhead conveyor which transports them to our finishing line where shot-blasting, grinding, inspection, painting and palletizing are carried out before being placed in storage.
