Sheet Metal Testing
For almost 100 years a test method to determine the level of quality of sheet metal exists. Abraham M. Erickson is considered the inventor of the cupping test and he patented this test method in the early 20th Century.
ERICHSEN develops for almost 100 years test and measuring instruments indispensable for surface inspection and therefore is closely connected to this industrial sector all over the world.
Corrosion creeps under coatings and attacks the products. To reduce these costly failure effects ERICHSEN offer a wide range of testing instruments. Some time or other almost every material will be attacked by corrosion.
Leonardo da Vinci, the artist, inventor and scientist of genius of the 15th century, manufactured among others a simple tensile testing instrument for wires - an early forerunner of modern universal testing machines.
