These pressures may cause expanded or contracted shapes.
Filcoflex can additionally add reinforcement rings to reduce contraction or expansion of the cylindrical shape.
Please contact us for more information for higher pressures, higher vacuum, or longer lengths.

Weighing Applications

Very suitable for high volume weight and capacity weighing and dosing applications where the required accuracy is >1kg. If the required accuracy is <1KG, please contact Filcoflex and explore Weighing Flexible Connections like silicone bellows, poly urethane bellows, PU-UF03 sleeves or PTFE 310 fabric.

Production Methods used

Joining / Bonding:

• Welding
  • HF high frequency welding
    Welding the material and cooling it down under compression with Radio Frequency to make the TPU material flow nearly seamless to form a uniform thickness with the original material wall thickness.
  • Heat contact
    with silver alloy heating element
    Welds are welded surface to surface after which the weld are compressed while cooling.
  • Hot air
    hot filtered and conditioned contaminent-, oil- and grease- free compressed air
