Presto Conical Bending Mandrel is a laboratory apparatus to bend coated test panels over a conical shaped mandrel in order to assess the elasticity or resistance of a coating paint or varnish to cracking; elongation and / or detachment from a metal...
Presto has recently introduced a crease stiffness HMI tester to test the crease resistance and board stiffness of various products like carton board, paper, printing, and packaging materials. The board stiffness and crease recovery are critical in the performance of cartons, especially on high-speed packaging machines and manual folding. The value of crease stiffness is technically important in the folding of carton blanks, most importantly during the release and closure.
Presto Color matching cabinet- Spectrum I Prima series has been designed to match the consistency of colors present in the product. This quality lab testing instrument has been designed accurately with correct light types and thus allows direct comparison of products that must have special color characteristics. Users will get five possible lighting types embedded in this testing instrument. These colors are supplied as standard: "D65", "TL84, "UV", "CWF" and "TFL”.
Bending test usually involves the measurement of ductility of different samples and materials. Through this test, the samples are taken to a specific limit to measure that how much load a sample can bear in order to measure the relationship of the material bending to load specification to generate material’s pass or fail criteria.
