Bellows  Manufacturers, Traders, Suppliers

As the inventor of the bellow, Arno Arnold has extensive knowledge of bellows. It became clear very early on that in situations where a lot of swarf is created, additional protection over the bellows improves their function and durability. We therefore developed additional telescopic sheets, which form a closed cover on the upper surface. They combine the advantages of a bellows, such as impermeability to fluids and dust, with the benefits of a telescopic steel cover, such as protection against hot and sharp swarf.
The telescopic sheets are made from stainless steel and are designed in such a way that they have an effective immediate deflecting effect. Depending on the space available, the sheets can be fitted so that they are movable or fixed in place. As it is particularly important that the metal sheets form a tight seal at the front, we recommend the use of our patented sheet system on the back. These create counterpressure, which means that the telescopic sheets provide a gap-free seal on the side that is exposed to impact from swarf.

Bellows made of rubber and soft PVC For special applications HEMA also offers bellows made of soft PVC, rubber discs and rubber fabric bellows. Rubber disc bellows Rubber disc bellows are high quality piston and spindle protection covers that provide complete sealing. Since each rubber disc lies on the other, excellent compression dimensions are achieved. Rubber fabric bellows The use of rubber fabric bellows is recommended for applications subject to particularly high wear, high pressure conditions or higher temperatures up to 200 °C. These bellows consist of a two-component structure, where the carrier material is coated with a special plastic.

LASERVORM offers high-precision laser welding for a wide range of products and component groups, from micro components to macro structures. Our specialty lies in producing precision welds on metal components at impressive speeds, utilizing advanced laser technology with both pulsed and continuous-wave lasers up to 3.5kW CW power and 7kW PW power.
