The plastics industry has seen an increase in the
sophistication and accuracy of the parts they are being asked to produce.
This has led to an increase in the need for their machines to be better
maintained and aligned.
To meet this need, Hamar Laser has developed several
lines of laser systems that quickly and accurately calibrate almost any
kind of plastics machinery. These lasers have dramatically improved extruder
barrel and screw life, injection-molding-machine mold/tool life, part-flashing
and reduced tie-bar expenditures. Film lines (blown and regular) have
also benefited greatly from laser alignment with significant reductions
in product wrinkling and wander.
Optics (borescopes and transits) have been the traditional method for
alignment in the plastics industry. While doing an adequate job, optics
are no longer good enough for today's high-tolerance marketplace, especially
when you consider that very soon entire engine blocks will be molded out
of special plastic resins.
Our laser systems are faster, up to 3 times in some cases, and much more
accurate that optics (0.5 micron resolution and plane flatness of 0.0000155"/ft
or 0.001mm/M). Lasers are much lighter and more portable, and easier to
learn and to use than most optical alignment systems (some optical systems
require 2 weeks of training).
We manufacture lasers to align extruders, injection-molding machines,
film lines and even the motors that drive them. We offer two basic types
of alignment systems for plastics processing applications:
Straight-Line Laser Systems - designed for
single and twin-barrel extruders bore and shaft alignment applications.
Continuously Rotating Laser Systems - designed
for injection molding machine and film line (roll alignment) applications.
Our continuously rotating laser systems come in 2
accuracy grades: the L-730 Precision Series and the L-740 Ultra-Precision
Series. Each series offers 4 different laser systems with single, dual
and triple-plane versions. The L-730 Series is designed for those with
accuracies needs of 0.00012"/ft (0.01 mm/M) or higher and the L-740
Series is for those with accuracy needs of 0.00002"/ft (0.0017 mm/M)
or higher.
Whether you are a manufacturer of injection molding machines or a user
of extruders, you will benefit from investing in our laser alignment systems.
In the majority of cases, our lasers will pay for themselves in the very
first year.
Depending on the application, prices range from $7,995 to $39,950.
