ISIMAT is a privately owned company that was founded in 1955 in Ellwangen, Germany.
The company soon gained an acknowledged competence in the design of screen printing
machines for printing on three-dimensional items.
ISIMAT's screen printing machines print with high accuracy and repeatability. The
machines maintain their print accuracy during their long operational lives, even in
heavy duty use. This has earned ISIMAT the enviable reputation of a supplier of high
quality screen printing machines.
Peter Detzner took over the helm in 1995. He transformed ISIMAT into a technology
driven company while maintaining its strong customer focus. ISIMAT has taken advantage
of developments in mechanical design, machine and motion control in the design of new
machines. Automated solutions and new technologies were developed to meet the increasing
demands of industrial decoration processes - repeatability, reliability, high production
speeds and short changeover times.
ISIMAT strengthened its sales force and expanded its network of international sales
partners. The company's growth has been consistent year rafter year. Engineering and
manufacturing required more space; the latest expansion in 2002 was a new production
hall of more than 1000 m2 with new office space of 280 m2.
Product Range
ISIMAT manufactures Screen printing machines for printing on:
Fascias, displays, housings, beverage crates,
drums, barrels, gas bottles, sea Is/gaskets, films
for in-mould decoration, conductive pastes,
etching pastes, coatings, etc.
Packaging tins, notepads, point of sale
displays, Candles, sporting goods, toys,
etc.
Quality Management
In the late 1990s ISIMAT established a Quality Management System to control its order fulfillment process:
specifying, designing, building,testing, shipping, installing, and commissioning. Suppliers were included
in the quality management through detailed technical specifications, goods inwards inspections, and supplier
assessments.
A successful independent audit to EN ISO 9001:2000 in February 2004 certified this Quality Management System.
ISIMATs intranet gives employees access at anytime to procedures and documents of the Quality Management System.
This ease of access helps to make the system effective; it has become a framework for continuous improvements,
and quality has become an integral part of each activity within the company.
6-Colour Screen Printing Machine for plastic tubes or cartridges
ISIMAT's TD6160 is a highly efficient, 6 colour screen printing machine for printing on plastic
tubes or cartdriges. The maximum production speed in 2-up operation is 160 items per minute.
The TD 6160 features a solid welded frame and a rotary indexing table. Cleaning, flaming and
UV drying with the ISI-StarUV drying system are standard. Precision of product handling in the
machine and repeatability of print cycles alfow the printing of high quality images with highly
accurate colour to colour registration.
The modular design of the TD 6160 allows each customer to select a configuration that matches
specific requirements. A machine can have a maximum of seven printing stations and seven UV dryers.
High reliability and high production speed make the TD616o ideal for 24/7 product ion. The option
of loading from a pin chain and unloading onto a pin chain allows the integration of a TD6160 into
an in-line production process from tube manufacturing to printing to packaging.
HIGH PRINT QUALITY
Each tube is oriented in two stages, coarse and fine, to maintain high accuracy
even at maximum production speed. A printed marker a cap recess is aligned above the
centre line of the mandrel. Any angular advance or retard for positioning the image
is set at the touch screen.
Registering in the printing stations is not required. The angular position of each
tube is known at all times as the mandrels are always in positive drive contact with the
machine drive, and vacuum hold-down prevents any movement of a tube on a mandrel. This
ensures colour to colour registration is accurate to within + 0,1 mm.
ISIMAT's patented squeegee pressure control system, PressControl, simplifies setting of
equal squeegee pressure at all printing stations and keeps the pressure constant during printing.
Sinusoidal acceleration and deceleration of the screens ensure smooth reversals of screen
movements at the reversal points to prevent vibrations.The result is a precise and uniform ink lay down.
SHORT SET-UP TIMES
Job specific settings of the machine can be stored, including settings of the
pre-treatment and of the ISI-Star UV drying system. The settings are then available
for recall and automatic machine presetting during set-up for a repeat job.
The screens are driven by an innovative differential drive. A single adjustment of the
drive sets the screen speed and screen stroke of each printing station. It is not required
to change gear wheels at the printing stations when the tube diameter changes.
The TD6160 has other time saving changeover features such as quick-change mandrels and a
register system for the screens.
The operator-friendly design of the TD6160 has benefited from the input of operators and work place studies.
HIGH UP-TIME
The use of high quality components and lifetime sealed bearings keeps the time required for
routine maintenance to a minimum. The modular design of the machine allows a quick change of
subassemblies,for example changing a gear module and its associated vacuum head requires only
a few minutes.
Remote diagnostics via modem and telephone line is standard.

LOOK....NO LABEL !
Plastic containers promote the brand image of their contents by reflecting the promise
that a brand stands for. Therefore, companies are looking for containers with shelf appeal.
When custom designed containers are not an option then high quality decoration of standard
containers can individualise the packaging. But this relies on printing of multicolour,
eye-catching images with consistently high quality. Images on containers have to be identical,
in particular when they are displayed side by side on shelves.
The increasing demand by consumer companies for high quality, multi-colour decoration, requires
solutions from ISIMAT as they enable contract printers and container manufacturing companies to
Reduce operations costs through
- Higher printing speeds
- Shorter set-up times
- Lower manning levels
- Less waste
- Lower maintenance requirements
Improve print quality through
- More colours
- Finer print resolution
- Higher registration accuracy
- Less variations of ink film thickness
ISIMAT has a complete range of modular designed screen printing machines for printing on plastic
containers. The machines can be tailored to provide solutions for customers' specific requirements.
An ISIMAT machine puts the operator in control of the printing process. Machine accuracy, uniform
ink lay down, and repeatability of print cycles reduce the need for 100% inspection. ISIMAT provides
effective pre-treatment and thorough cleaning of containers to minimise the risk of screen contamination
by dirt. The use of UV inks eliminates the danger of image areas being contaminated by dried ink.
The ultimate compliment to direct screen printing is the effort made by companies that use other
decorating methods to create the "no label" look. ISIMAT's screen printing machines put direct screen
printers ahead. Up to seven colours, extremely accurate colour-to-colour registration, uniform ink lay
down, and excellent repeatability provide for vibrant, photo-quality images. With ISIMAT the result is
"Look - no label!"
ISIMAT's screen printing machines are tailored to match customer's specific requirements. All machines
can print with UV inks or solvent based inks, provided they are fitted with UV dryers or hot air dryers
respectively. ISIMAT can supply the machines with integrated pre-treatment - flaming or corona - units,
de-ionising units and effective dust extraction. High speed machines can be linked to existing high
speed conveyors or can be supplied with an unscrambler.
UVitro® Surface Treatment
UVitro® - what is it?
UVitro® is a surface treatment process that modifies the sub-microscopic surface properties
of materials. It created a homogeneous, sub-microscopic roughness that ensures lasting
adhesion when the surface is subsequently coated with a UV curable product.
UVitro® can be integrated into industrial production process such as coating or direct screen
printing.
UVitro®'s success story began in glass decoration. Treating glass surfaces with UVitro® improves
substantially the adhesion of UV inks in direct screen printing. This gives glass decorators the
option to change from ceramic enamels to UV inks. UVitro® also ensure! lasting adhesion of
UV lacquers to glass.
UVitro® makes it possible for companies to switch to UV curable products - inks, lacquers, adhesives -
in applications that were previously ruled out. UV curing is a preferred drying technology based
on extremely low emissions of volatile organic compounds (VOCs), low energy consumption and
high quality finishes.
UVitro® enables companies to comply with existing and forthcoming environmental legislations such
as Directive 99/13/EC (limitations of emissions of VOCs) and to promote and environmentally friendly
image.
UVitro® - a success story in glass decoration
Traditionally, thermoplastic ceramic enamels have been used for direct screen printing onto glass.
After printing, ceramic enamels have to be fired into the glass in a lehr at a temperature of up to 610 °C.
But ceramic enamels are toxic; most enamels contain heavy metals. ISIMAT conducted a research project
to develop a process that would significantly improve adhesion of organic UV inks to glass surfaces.
This would enable glass decorators to comply with environmental legislation such as Directive 94/62/EC
(packaging and packaging waste).
The successful completion of the project delivered a process for
modifying glass surfaces: UVitro®.
UVitro® surface treatment creates a sub-microscopic roughness that ensures lasting adhesion of
UV inks to treated glass surfaces. The innovation of UVitro® was recognised by the granting of
patent protection. UVitro® can be integrated into high-speed, multi-colour screen printing machines.
It does not increase the complexity of direct screen printing with UV inks onto glass; glass items a
treated before they reach the first printing station.
Glass decorators can gain the following benefits of printing with UV inks:
Enhanced Print Quality
- Practically unlimited colour range
- Finer mesh, resulting in higher resolution graphics
- Good opacity and brilliant gloss finish
Improved Production Process
- Drying times are reduced from approximately 90 minutes to a few seconds
- Colour variations due to temperature fluctuations in a lehr are eliminated
- UVinks are easy to handle, no drying of inks in screens
Reduced Production Cost
- No energy-hungry lehr
- No floor space or capital is needed for lehr, push bar stacker, transfer conveyors etc.
- No scrapping of up to 90 minutes worth of production when a problem is detected after firing in a lehr
- No expensive heated stainless steel screens required
Reduced Environmental Impact
- Organic UVinks are free of heavy metal
- Virtually no VOCs are emitted when UV inks are cured
Glass containers that were treated with UVitro® and then decorated with UV inks have passed
filling line simulation tests for single trip containers, and the images did not lose their brilliant
gloss during more than 500 cycles in a domestic dishwasher.

Spray Coating with UV Lacquer for glass and plastic bottles and jars
The SCL 2730 UV spray coating line uses UVitro® technology and a new innovative spray coating technique that applies
newly formulated UV lacquers from Japan. UVitro® ensures lasting adhesion of UV inks and UV lacquers to glass. UV
lacquers are applied with spray guns and can contain up to 90% solids. The coating thickness is between 3 µm and 20 µm.
The UV spray coating process is environmentally friendly and the high productivity machine is capable of an output of up
to 130 coated glass bottles per minute.
The SCL 2730 UV significantly increases the economic efficiency of the coating process for glass bottles. Compared with a
conventional coating process - whether it be solvent based, water based, or powder-the UV lacquer spray coating process
gives the following benefits:
- production speeds are higher
- batch cycle times are reduced
- changeover times are shorter
- heat treatment process is eliminated
- number of rejects is lower
Spray Coating with UV Lacquer up to 130 bottles/minute
The SCL 2730 UV features a 20 m conveyor chain with a chain pitch of 38.1 mm. The production speed is up to 5 m/min.
Bottles are placed onto the jigs and moved to the pre-treatment station where they are flamed to burn off any coatings
from the manufacturing process, then UVitro pre-treatment deposits an adhesion promoter onto the outer glass surface,
and lastly the bottles are thoroughly cleaned. After pre-treatment the bottles are moved through the spray chamber where
they are coated with UV lacquer. Then they are moved through the setting zone. The setting zone is heated to a temperature
of 70° C by IR heaters to enable the layer of UV lacquer to even out. Leaving the setting zone the bottles reach the UV
curing zone where powerful UV lamps cure the UV lacquer. Finally the bottles are discharged after leaving the UV curing zone.
Compared with conventional coating, spray coating with UV lacquer offers a number of benefits to the user:
The drying time is reduced from approx. 20-30 min to approx. 3min and the production speed is increased from 3 m/min to max 5m/min.
As a result the cycle time is reduced from 40 minutes to 5 minutes. Should a fault occur, less work in progress is affected.
The colour of the coating can be changed within 10 minutes.
The number of jigs required is only about a tenth, as the chain length of the SCL 2130 UV is approx. a tenth of the chain length
of a conventional coating line. Floor space requirement is reduced, and although the SCL 2130 UV is smaller than a conventional
coating line, its output is 60% higher.
Energy cost is reduced by up to 80% because a UV spray coating process does not require an electrically heated drying oven with
temperatures of up to 2oo°C. The overall running cost is 60% lower than a solvent or water based coating process, 30% lower than
a powder coating process. This cost reduction does not include the saving in capital cost; the price of a UV spray coating line
is significantly lower than the price for a conventional coating line.
