The equipment is designed to reveal the cupping qualities of metal sheets and strips. It can also be used for testing adhesion, elasticity and porosity of coats of paints or varnish by way of comparison. The material after fracture gives in grain structure and contitution.

Features:

• The big handle and the intermediate gearing provided make easy pressing and swelling out of the charged sheet metal by the punch.
• It is easy to get the pointer to zero as the top of punch and furrow holding plane are always kept to coincide by measurement correction panel.
• A necessary tolerance, 0.05mm is obtained by the rear back screw, easily and precisely.
• By utilizing the attached test piece holders, suitable tests for nos. 1,2 and 3 test pieces, can be easily performed at the most normal location.
  

Installation:

It is recommended that the machine is mounted on a table. It reserves rights of change in the above specification due to constant improvement in design. The dimensions given above are all approximate. Erichsen tester is designed to carry out Erichsen Cupping test on metals.
