Oldroyd is the top dog in the area of waterproofing against rain and holds over 90% of the market share in the Nordic countries. The key to success lies in the innovative strength of the family business in Stathelle (around 160 kilometers south-west of Oslo). Originally concentrating on film extrusion, founder John Oldroyd Cheetham also accessed the injection molding technology with the help of KraussMaffei and now successfully operates three hydraulic CX 160-750 with a clamping force of 1600 kN.
So-called spacers, curved products with grid structure, which create a distance between rock and membrane, are produced on these machines in a cycle time of roughly 15 seconds. They weigh approximately 150 grams, whereby there are around 20 different models, varying in diameter and height.
