Development workshops

We perform custom-made machine fitting production:

  • Turning works
  • Welding
  • Machine fitting works
  • Suspension hooks, wall ties and supporting constructions etc.


We produce analytical sieves with standard dimensions (according to ISO 3310, ISO 5223, EN 933; compatibility with sieves of other producers:

Ø 100 mm (frame – stainless steel and brass)
Ø 200 mm (frame – aluminium and stainless steel)
Ø 300 mm (frame – stainless steel)
Ø 400 mm (frame – stainless steel)
500×500 mm (frame – varnished sheet metal)
150×430 mm (frame – wood)

  • we can arrange the calibration for produced/repaired sieves, including calibration sheet, in calibration laboratory
  • the sieves have a rubber sealing on the interface of frame and screening partition, which prevents accumulation of sample particles in frame joints and their undesirable release into following sample batches
  • we repair all sieves made by us, i.e. replacement of screening partition (saving of 40 – 55 % compared to new sieve)
  • we offer wide accessories for sieves (lids, dishes, reductions, laboratory screening machine, etc.)
