Is it possible to fully automate the production of seals for household appliances such as vacuum cleaners, irons and food processors?

Yes, and it doesn't matter whether they cut the seals from strips or tubes. A line always takes the material from the extruder and cuts it to the exact length, creates the necessary openings, slits or perforations and deposits the material. Such lines are profitable both for manufacturers of small electrical appliances and for suppliers who produce finished gaskets or seals.

Metzner ST-OB: a robust universal cutting machine

The Metzner ST-OB is a universal cutting machine for materials with a width of up to 150 mm | 5 ²⁹/₃₂” and a height of up to 30 mm | 1 ³/₁₆“. It is available with tools for punch, shear, pull and blade cutting and works with length intervals of 0.1 mm | 0.004”. A special feature of the ST-OB is the cylinder, which was specially developed for the machine and ensures very fast and powerful cuts. In addition, the operator, who is familiar with the material, can finely adjust the pressure with which the material is fed to the blade. This makes it possible to cut silicones, for example, with excellent results.

A modular system with 10,000 combinations: Metzner MBS

If you manufacture seals for small electrical appliances, the Metzner MBS is an ideal solution.This is a modular system of standard tools for pretty much all types of processing. Punch, shear and draw cut as well as drill, blade, hot and tool cut are the most common tool examples. Of course, there are also various other tools for this seal and gasket cutting machine. A total of approx. 10,000 combinations are possible. This means that MBS can also produce complex seals, such as those used in food processors or irons. Of course, the cut is made exactly at the choosen position. The repeat accuracy is ± 0.2 %, the length interval is 0.1 mmm | 0.004″. A special feature is the eccentric tool, which performs up to 400 cuts per minute in start-stop mode.The stop before the cut ensures that the cut is made at exactly the right angle. You can also equip the single machine with two tools so that several tasks can be carried out automatically in one work step. Tools can of course be changed easily and manually, so that you can use the MBS in a variety of ways. You can also reorder tools thanks to the modular design. Customized tools are also possible. There is also the option of equipping the machine with pre- and post-processing solutions such as trays. The MBS is available in three sizes: for material up to 100 mm | 3 ¹⁵/₁₆“, up to 200 mm | 7 ⁷/₈“and up to 390 mm | 15 ²³/₆₄” wide with a maximum height of 80 mm | 3 ⁵/₃₂“. Metzner can also customize the MBS software so that it fits perfectly into your processes.

Customized and software-adapted automation solutions

Despite the wide variety of solutions, there are cases in which neither the ST-OB nor the MBS is the perfect solution.
