On this page you'll see how a flat gasket comes to life.

To illustrate the process, we've put together a short series of photos. Please click on the photo sequence.

The graphite sheets are stored flat on shelves. Because the properties of graphite are not affected by the surrounding ambient conditions, such as include light, temperature, humidity, etc. (meaning it doesn't age), the method of storage is not critical.

Also not critical is the storage of the stamping tools. These are made of weather-proof wood, sharply ground steel banding (cutting line) and a retaining rubber made of foam rubber.

ZAt the start of the production process, the graphite sheets and the tool are taken from stock and brought over to the stamping machine. Our machine line-up comprises of several travelling head presses, swivel arm presses and a gantry press. We have modified some of these machines, and therefore fully automatic production of large quantities is possible.

During stamping, the sheet is transformed into a punch grid, cut-out disks and of course into gaskets.

The tool is then returned to stock and, after being checked for cutting tolerances, stays there for the next use. The punched grid and the cut-out disks are also put in stock. They are used later for gaskets with smaller dimensions, thus assuring economical use of material. The gaskets are then sent for packaging. Here we employ either the skin-process where the material to be packed is fixed with a plastic film to a carton. This process is known from the so-called "blisterpacks", which are now used for almost all products. As an alternative, we use cardboard tubes. This type of packaging is especially interesting when gaskets in series production are encountered. This allows them to reach their destination well protected, in good condition, and may be automatically removed when needed.

We generally use anonymous packaging, without our company name printed on it. Applying a label with your name is of course always possible. We can also use your own packaging if you'd like.

Now, only the shipping documents need to be drawn up, and then the gaskets are on their way to you or your customers with the shipping documents.
