Metal printing
Metalphoto is the preferred material for nameplates, control panels and bar codes in applications where service life expectations exceed 20 years for the part. Government & aerospace extensively specify Metalphoto for demanding applications that require resistance to the effects of weather, abrasion, heat and most chemicals. The following performance requirements are taken from reference documents, in which Metalphoto is used and specified, in order to demonstrate the unique durability of the product.
