Cylindrical Mandrel is a robust bend tester used to determine the flexibility, adhesion, elasticity and elongation by bending the fully cured coated M.S. Panel or Specimen over a cylindrical mandrel. It consists of a frame which has a bending lever with height adjustment sliding vise and panel fixing knob. Mandrels and knobs are made up of Stainless steel or hardren material and rest parts are made up of high quality mild steel with powder coated for durability.
M.S. Panel or Specimen is clamped after adjusting the height and fixed with panel fixing knob and it bent over a mandrel about 180° and observed for deterioration of film in terms of flexibility, adhesion, elasticity, elongation etc. The instrument can be adjusted to a different diameter of the mandrel by changing it. The mandrels are easily changeable.
Raj produces 12 mandrel sets with sliding vise and knobs for fixing the specimen or panels properly. Always conduct the test from high size mandrel to lower size mandrel for proper observation of the result.
