Our technologies at a glance

Raw material handling & pre-assembly

  • Fully automatic and sensor-supported assembly process for inserting membrane bundles into the polycarbonate or polypropylene housing

Tests

  • 100% Integrity tests for fiber integrity and housing tightness
  • Several inspection steps for quality assurance
  • Optionally also with special fully automatic photo and sensor technology

Heat sealing

  • Fully automatic sealing of hollow fiber membrane using infrared

Drying

  • High-precision measurement of filter fiber integrity using ultrapure water (wet density test)
  • Semi-automatic drying using microwave technology or
  • Fully automatic, robot-guided process with wet leak test and hot air drying in one position

Gluing

  • Fully automatic and high-precision dosing of adhesive components
  • Potting the filters by centrifuging

Product handling

  • Manual or automatic loading and unloading using sensors and gripper systems (pick and place systems)
  • Manual to fully automatic product transport via conveyor belt possible

Cutting

  • Coarse and fine cuts for sequential removal of the casting compound

Production data acquisition

  • Recording of essential basic data (can be extended as required by the customer, e.g. input and output weights, manual assignment of error codes, automatic blocking of products with errors)
  • Barcode & product label labeler

Assembly

  • Sensor-supported assembly processes for applying filter caps, inserting O-rings and for plug assembly
