A FAST AND
EASY WAY TO MARK GLASS, METAL,
PLASTIC AND MANY OTHER MATERIALS
The M7990 is excellent for trade name marking. With the vacuum system it is virtually dust
free. The
marking area 1-3/4" x 1-1/2". Each blast will
give an even mark, It does not penetrate deeper in the center. Ideal for
marking flat glass, plastic, fluorescent tubing and other materials.
The M7995 is our newest floor model with Dust System. Although its outside
appearance is similar to the M7990 the many changes are inside. This unit has all
the reliability and precise etching ability of the M7990 but now it can etch an extra large
marking area of 2-3/4" x 2".
PRINCIPLE OF OPERATION
Part
to be marked is held firmly on rubber mask which is mounted to cut out
stencil plate. A blast of grit through mask produces etched mark on surface
of part. Time of blast and air pressure are controlled by setting timer and
air regulating valve. Grit is then returned to hopper for reuse.
MASKS
The
etching masks are molded from different types of rubber; synthetic or
natural. The masks are relieved with stencil style characters, special
designs or trademarks which are reproduced with amazing clarity. The
durability and quality provides long life. Cost per mark is extremely low.
The mark is not limited to flat surfaces. Tubular, convex or concave shapes
can be marked with the use of a nesting feature.
