Lectroetch semi and fully- automated marking systems are designed for high production metal marking needs. The rugged, heavy- duty design of these units allows many years of trouble-free etching. The units consist of a pneumatic-operated cylinder which moves the marking device to the part. Solid-state controls regulate the etching cycles as well as current output to assure a constant etch. These compact units may be incorporated into almost any production or inspection line. The units can be tooled to the customer’s special needs—up to and including completely automated marking systems—with loading and cleaning capabilities.
