IMPORTANT: Don’t laminate one-of-a-kind documents unless ou are sure of our
laminating skills and can afford to damage or ruin the document. Don’t laminate
valuable items such as stamps, baseball cards, autographs or other collectibles
because the value of such items can be destro ed b lamination. Collectors generall
value these kinds of items onl in their original state.
Remember that ou cannot laminate thermal paper, such as t pical fax paper, because
it is activated b heat and will turn black. Also, remove paper clips and staples because
the can damage the rubber rollers. Be careful about laminating an thing that will be
affected b heat. For example, the colors in cra on drawings ma run together or be
smeared, especiall if the cra on la er is heav . Light cra on drawings ma not be
affected, but test an expendable sample of an item that ma not laminate well.
IMPORTANT: Éviter de plastifier du papier thermosensible, comme le papier de
télécopieur, pus u’ll noircira sous l’effet de la chaleur, et enlever les trombones et les
agrafes gul ris uent d’endommager les rouleaux de caoutchouc. Prendre certaines
précautions avant de plastifier des articles susceptibles de réagir à la chaleur comme
les dessins au pastel dont les couleurs baver et se mélanger, surtout si la couche de
pastel est épaisse. Les pastels en couche mince peuvent ne pas réagir, mais, en cas
de doute, il est préférable de faire un essai avec un échantillon perdu.
Ne pas plastifier les documents importants dont il n’existe u’un seul exemplaire, à
moins de bien malitriser la techni ue de plastification. Ne pas plastifier non plus les
articles de collection comme les trimbres, les cartes de baseball, les autographes ou
autres, ui peuvent perdre leur valeur pour les collectionneurs s’ils ne sont plus dans
leur état d’origine.
IMPORTANTE: Recuerde ue no puede laminar papel térmico, tal como el papel de
fax tipico, ya ue es activado por el calor y se tornará negro. Retire también cual uier
sujeta-papeles o grapa, puesto ue pueden danar los rodillos de goma. Evite laminar
cosas sensibles al calor, por ejemplo, los colores de dibujos hechos en lápiz de pastel
pueden no ser afectados, pero ensaye con alguna muestra descartable, en los ìtemes
ue podrían no laminarse bien.
No lamine ningún documento único, a no ser ue esté muy seguro de sus habilidades
de laminador y pueda permitirse arruinar el documento.No lamine artículos de valor,
como estampillas, tarjetas de béisbol, autógrafos, u otros coleccionables, ya ue su
valor puede ser destruido por la laminación. En general, las coleccionistas valoran
este tipo de artículo en su estado original.

1-2 FEATURES & BENEFITS
Your new laminator has several standard features that set it apart from other models.
•Intelligent heat controllers simultaneousl displa both the set temperature and
the actual temperature. The microprocessor-based control quickl learns to
anticipate the heat demand of each job and keeps the actual temperature within a
few degrees of the set temperature.
•Laminating and pull rollers are covered with qualit silicone rubber for superior
release, higher lamination qualit and easier cleaning. The laminating rollers and
pull rollers are interchangeable.
•Removable heat shoes are teflon coated to reduce film abrasion. The can easil
be unplugged and taken off to facilitate cleaning or replacing the laminating rollers.
Built-in retractable slitters save an enormous amount of cutting time b trimming
awa side scrap during the lamination process. The two heads can be adjusted
independentl with great precision, even while the laminator is running.
•Forced air cooling is essential when running thicker films, because the lamination
needs to be cooled to get good results.
•Eas access controls are convenientl located and grouped for effective operation.
•The safety guard is built into the feed tra to make sure it will alwa s be in place
when laminating.
•The precision feed tray has moveable left and right side quides and can be
replaced with the optional Power Feed Tra in seconds.
•Laminating and pull rollers are covered with qualit silicone rubber for superior
release, higher lamination qualit and easier cleaning. The laminating rollers and
pull rollers are interchangeable.
•Very strong steel cores. These prevent roller flexing and insure uniform pressure
across the width of the laminate, giving ou the best qualit lamination available in a
medium-dut commercial machine.
•Controls to open and close the laminating rollers. The controls make threading
easier and allow even heating of laminating rollers during warm-up.
•100% Made in the U.S.A.

1-3 OPTIONS
•Power Feed Tray is designed exclusivel for the HD-25, this power feed tra has
received good reviews for its eas setup and accurac . Autofeeding is the first step
toward automated lines and lower production costs. A separate specification sheet
is available.
•2 ¼-inch supply roll mandrels are available at no additional charge at time of
purchase in place of the standard 3-inch mandrels.
•Risers lift a machine off its work surface, allowing longer suppl roll brackets
(extensions) to handle larger diameter rolls of film. Risers are not needed with a
stand.
•Stand An extruded aluminum stand is designed to place the unit at optimum
feeding height and to provide a secure base. Casters are available for either stand,
but it is suggested the be removed for stabilit and safet once the machine is in a
permanent location.
•Upper fan assembly. When running thicker films, additional cooling capacit
enables work to be run at a higher speed.
•Scrap rewind. Enables cold lamination b removing the release liner material from
pressure sensitive adhesives, film and vin ls.
•Footage counter. For accurate measurement of film usage.
•Additional slitter heads. For multiple-up trimming.

1-5 PRINCIPLES OF OPERATION
The HD-25 “Workhorse” laminators operate b pulling film with a thermall activated
adhesive over a heat source and into a set of laminating rollers. Film from the suppl
rolls passes over heat shoes to activate a pol eth lene adhesive la er on the film. It
then passes through rubber rollers to appl pressure and bond the film to the item being
laminated. The adhesive is pressed into the ink and fibers on the surface of the paper.
The strength of the lamination bond can be checked b cutting a large “X” on the
surface of a laminated sample with a sharp blade. Use the tip of the blade to pr up one
corner of the “X”. Grab that corner and pull up the film. Ink and/or paper fibers coming
up with the la er of film indicates a good adhesive bond.
If the film comes up too easil , with no ink or paper, the lamination was probabl done at
too low a temperature. Check the instructions that ma have come with our laminating
film and/or the lamination temperature chart in section 5-5.
Please note that when doing an X-test on gloss (coated) paper, a good X-test will pull
up ink onl . The film should not come up easil . When laminating material that is not
gloss (uncoated), the paper is often more fibrous and a good X-test will ield ink and
paper fibers coming up with the film.

1-6 LAMINATING FILM
Most thermal laminating film consists of two la ers: a base of pol ester and an adhesive
la er of pol eth lene. The pol ester la er forms the harder outer surface of the film and
does not melt at laminating temperature. It provides rigidit and protection for our
laminated items. The greater the pol ester content, the higher the level of protection,
rigidit and luster. The pol eth lene la er melts at laminating temperature and bonds
the film onto the subject material under the pressure of the laminating rollers. As an X-
test demonstrates, the adhesive is pressed into the paper and fills irregularities in the
surface.
The proportion of pol ester and pol eth lene in a film is usuall described with
numbers. For example, a “1-2” film consists of one mil of pol ester and two mils of
pol eth lene. The first number refers to the base la er. The second number refers to
the adhesive la er. A mil is 1/1000 of an inch.
Since pol ester is the more costl of the two t pes of plastic generall used in
laminating film, a “3-2” film will cost more than a “2-3” film. Both are 5-mil films but the
“3-2” version will seem a little thicker on a piece of laminated material because it will be
slightl stiffer. Thermal laminating films are available in man different base/adhesive
combinations. Five mil film, for example, can be found in 1-4, 2-3, 3-2 and 4-1
combinations.
In the US laminating trade, the generall accepted practice is to describe two-sided
lamination, or encapsulation, b the thickness of one la er of film. For example, “3-mil
lamination” should refer to lamination with two la ers of 3-mil film. If ou are bu ing or
selling laminating film or lamination services, please make sure both parties understand
the film descriptions being used. There is a huge variet of thermal laminating films
available to suit man different kinds of application. Here are some of the more
commonl used “special” film t pes or film additives:
•film with low-melt adhesives, also known as co-pol mer films; these often have
better clarit and are less likel to curl or ripple
•matte films to eliminate glare or to accept printing or writing; man suppliers offer
films with both gloss and matte finishes
•film with UV inhibitors to protect colors in the laminated material from fading in
sunlight
•thermal film that has a pressure-sensitive adhesive and a release liner on its outer
side; for example, a poster with this material laminated on the back could easil be
mounted without fasteners or tape
•“liner films” with a protective liner on the top outer surface...after a piece of material
has been laminated, trimmed, packed, and shipped, the person using the material
10

can remove the protective liner revealing a surface perfectl free of dust, scratches
or abrasion
•opaque or colored films for the back side of a lamination; these can form a border for
a laminated piece
•iridescent clear films for special visual effects
•permanentl waterproof films for outdoor, underwater, or special applications; the
most common thermal laminating films are made with water-based primers and will
eventuall de-laminate if continuall exposed to water or weather; trul waterproof
films are made with special primers
Rolls of film ma be purchased in different widths. The size of the laminator is the onl
limitation to the width of the film rolls ou can use. Make sure the upper and lower roll
widths are the same, and are aligned with each other.
When installing film, alwa s center the rolls of film on the suppl roll mandrels. Because
it does not hold heat well, 1.5 mil film can be the most difficult gauge of film to use. A
standard 1.5 mil film will run at about 310 °F, while a 3 mil film with the same adhesive
t pe will run at 280 °F. Even when applied at 310 °F, the 1.5 mil film will not adhere as
consistentl as the 3 mil film applied at 280°F, or a 5 mil applied at 250°F. For man
applications, 5 mil film does a much better job of protecting and enhancing items.
Ten mil film is suggested for those applications that need the most protection and
rigidit . Seven mil films are also available.
Rolls of film are sometimes spliced. Most film suppliers will mark a splice with colored
tape. This wa , ou can see the splice as a “dash” of color on either end of the roll. If
ou spot a spliced roll in advance, ou can put it on the top suppl roll mandrel in order
to see the splice coming more easil and avoid putting material under the splice. Or
ou could put it on the bottom roll if ou plan to be laminating items that will never be
seen from the backside.

5-1 SET-UP & OPERATION
With the laminator on an unobstructed, level surface, perform the following
checkout before threading the machine with film.
WARNING: Make sure the power cord is clear of the underside of the
machine prior to operation to avoid overheating the cord.
MISE EN GARDE: S’assurer que le cordon d’alimentation ne passe pas
sous la machine, ce qui l’exposerait à la chaleur élevée produite par le
sabot infèrieur
ADVERTENCIA: Antes de operar la máquina, asegúrese que el cordón
electrico no está debajo de la misma, para evitar el recalentamiento del
cordón
1. Remove all packing straps, rubber bands, tape, and plastic ties from the
machine. Remove the protective paper from the safet shield. Unwrap
and put in the feed tra sections. Remove the protective paper from the
safet shield. Remove the protective material from the slitter blades. Be
careful to keep our hands awa from the blades.
2. Make sure the master switch (at the back of the unit next to the power
cord), the heat switch, fan switch, and the drive switch are turned off.
3. Connect the machine to a 220V single–phase power source of at least
20 amps.
4. Turn on the master switch (at the back of the unit next to the power
cord). The power indicator on the left front panel should light. Turn the
heat power switch to the ON position. Both heat controllers should go
on. The upper window of each unit displa s actual temperature, the
bottom window displa s the set temperature.
5. To change the set point temperature to a desired setting appropriate to
our film/application, simpl depress either up or down arrow button for
3-5 seconds until the bottom window displa starts to increase or
decrease. Continue depressing the respective arrow till ou’ve reached
desired set temperature, then release the arrow button. Wait
approximatel another 3-5 seconds till the entire displa flashes once
indicating the parameters are now set and will be held until manuall
changed again, even if the unit is turned off and on.
The Chromalox heat controllers come set with a 400 degree F high limit.
The highest common operating temperature setting for this machine
18

would be 325° F with a standard 1.5 mil film. For the vast majorit of
applications, the temperature should never be set higher than 350° F.
For 3 to 10 mil low-temperature films, the temperature would be in the
200-260° F range.
6. Turn the fan switch to the ON position. You should hear the fans begin
to operate. Turn the fan switch off.
7. The laminating and pull rollers are shipped in the open position. Turn the
two large 3-arm knobs on the right side of the unit counter-clockwise to
close the laminating and pull rollers. Open and close both sets of rollers
several times. Notice that starting from the “open” position there is first a
“closed” position and a “closed & locked” position for laminating.
Both rollers must be in the “closed & locked” position for laminating.
Leave the rollers open if ou are not going to thread the machine now.
Alwa s shut down or ship the machine with the rollers open. Close the
rollers if ou are about to thread the machine.
8. Turn the drive direction switch to the FORWARD position and turn the
drive power switch on. The pull rollers and the laminating rollers should
rotate. Turn the drive power switch off.
