A FAST AND EASY WAY TO MARK GLASS, METAL,
PLASTIC AND MANY OTHER MATERIALS
The M7990 is
our newest model and is excellent for trade name marking. With the
vacuum system it is virtually dust free. The venture chamber can
be exchanged for different marking sizes. One will mark an area
2-1/2" dia. The other will mark an area 3/4" x 2-1/2". 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.
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.
