The SAM Group Quarterly Newsletter – October 2015
SAM (Sung An Machinery Co., Ltd), a global company and market leader, designs and manufactures an extensive range of machinery
for the printing and converting industry. Products include extrusion coating, solution coating, and rotogravure printing machines as
well as individual components. These technically advanced machines deliver high productivity and a quick return on investment. The
company has three research labs and technical centers in Korea and New York. SAM has installed more than 600 machine lines in 31
countries. Solutions start with SAM.
Major R & D Expansion at SAM Headquarters
Construction of SAM’s new Research & Development Center is expected to be completed in January of 2016. This facility will be home
to the new SAMLab 3 – Solution Coating Technical Center, a semi-production facility designed for customer product development trials,
demonstrations, toll coating, solution coating trials and internal research and development. SAMLab 1 (Sungan Printed Electronics
Laboratory) is presently located in the main production area will be relocated to this facility and allow for addition assembly floor space
and consolidate the technical centers.
The R & D Center’s new building is 15,600 sq. ft. (1450 m²) and is a clean room facility for precise optical film coating. The center will
be fully equipped with analytic instruments, such as a high accuracy peel strength tester, optical property measuring system and humidity
chamber. Mr. Ryu has been named as the Director of R & D for the Center and possesses over two decades of coating industry experience
ranging from optical to functional conductive film for touch screen applications. Mr. Ryu will have a staff of five highly trained engineers
and technicians to effectively serve SAM’s customer demands.
SAMLab 3 – Solution Coating Technical Center’s pilot coating line machine will be fully installed in March 2016 and will be managed by
Mr. Y.B. Kim. The machine is designed for running water and solvent based, 100% solids, and hot melt coatings with a maximum width
of 1,060 mm at 600 meters per minute (bypass speeds up to 1,000 meters per minute). The line will have modular coating capabilities of
slot die, micro gravure, pressurized chamber doctor blade, direct/reverse/offset gravure, S-knife (comma), reverse roll, semi-flexo, 5-roll
and transfer roll to start. The line includes a 22 meter, 7 zone flotation and roll support dryer, one of the largest and most versatile in the
industry. Unique features of the machine line are automatic turrets at the primary unwind and winder for continuous running. Additional
features include a secondary unwind for wet and dry laminations, corona treatment, web cleaning and UV curing.
High Speed PP Extrusion Coating Trial and Bond Strength Test Performed at
SAMLab 2
Lotte Chemical Titan (Malaysia), together with SAM Asia, recently
performed polypropylene bond strength trials using SAMLab 2 –
Extrusion Technical Center located at SAM North America. The
intention of the trials was to determine the limits of high speed
extrusion coating while maintaining industry acceptable bond
strengths under close to real world production conditions.
The first trial at the Phoenix NY facility gave SAM engineers insight
on how to improve PP screw design and mechanical modification
of the SAM NA pilot line’s existing equipment in the die and chill
roll area, all specific to PP extrusion. The first trial process
conditions were evaluated with input from Lotte, SAM Korea and
SAM NA to improve the overall process conditions for higher speed
operation.
After equipment modifications were completed, a second trial was
performed using printed OPP as used in flexible packaging for the
snack food industry. Bond strengths were measured against a
reference sample produced at 820 fpm / 250 mpm.
variation when compared to the reference sample. The trial results
proved acceptable and stable high speed extrusion coating is
possible up to 1800 fpm / 548 mpm. (Note this was the maximum
pilot line speed as limited by extruder capacity).
Although the trials and machine setup concentrated on bond
strength only, we were further encouraged as the samples
produced with Lotte’s L-670M PP also showed minimal edge bead
averaging 6-8 mm width per side and proved excellent edge
stability at maximum speed.
Converters, with the proper resins, tools, and techniques, can plan
to coat at high speed with lower melt strength materials historically
considered speed limiting. The new design modifications for PP
extrusion can be supplied as standard on future extrusion coating
lines or as a retrofit upgrade on most existing SAM extrusion
coating lines.
Please contact your local SAM or Lotte representative for further
information or to arrange for your own trial.
The trial samples tested within the peel strength range of the
reference sample and results show a tighter spread of peak to peak

Technical Presentation: Monday, October 26 - 10:30 am
Development of Slot Die Coating Unit with Vision-Base Thickness and Meniscus Control for Reliable Thin Uniform
Film Coating, presented by Dong Kwon Choi of SAM
The roll to roll process is a key technology in the flexible and printed electronics market due to its ability for mass production
resulting in low cost. The need for ultra-thin, uniform coating technology is increased for the flexible electronics of OPV, OLED.
The technology for this reliable coating process control and monitoring function was developed in the Sung An Printed
Electronics Laboratory (SAMLab 1).
The presentation will introduce newly developed slot die coating unit (SDC-series) for which SAM was awarded the 2015 AIMCAL
Technology of the Year award. The key process parameters in the slot die coating process are the coating gap, speed and flow
rate. Other key parameters in the reliability of the coating process are in-line thickness and meniscus monitoring feedback to
the ink flow rate controller. The use of multiple vision cameras and precise linear stage units, the SDC-series achieves the
reliable uniform coating film thickness control and in-line monitoring. These systems are tested investigated with by measuring
surface resistance of coated PEDOT: PSS film.
Brady Corporation’s Versatile Pilot Coating Line Still Going Strong
In 2008, Brady Corporation, an international manufacturer and
marketer of complete solutions that identify and protect premises,
products and people, purchased one of the most versatile pilot
coating machines in the world from Sung An Machinery,
LTD. Brady's pilot coating machine is used for internal product
development as well as product development for their current and
potential customers.
One of the key features to the machine is having production size
coating equipment which is directly scalable to Brady's many
manufacturing machines around the world. The pilot coating
machine was one of SAM's first in North America. Brady was able
to obtain significantly more capabilities from SAM than other
machinery manufacturers around the world for the same
investment. The machine is capable of running water based and
solvent based coatings on a wide range of coat weights with
multiple drying techniques on paper, films, and foils. The
partnership between Brady and SAM remains strong as Brady
allows SAM to bring its potential customer in for reference machine
visits and SAM recommends Brady's pilot coating machine for new
product development

TECH TIPS
A View Inside the Extruder: Modeling the Extrusion Process
By Beth M. Warren, PE, SAM North America, LLC and Optex Process Solutions, Inc.
Abstract - When it comes to the extruder, the screw is a hidden entity. We know what is put into the extruder and have a good idea of
what comes out but there are many unknowns in between. This paper will look at process modeling of the extruder using a software
package from Compuplast called Virtual Extrusion LaboratoryTM. The basics of the software will be discussed and the parameters needed
to successfully model the screw, including rheology of polymers.
Once the model is created, how can it be calibrate to be as accurate as possible? A real life example problem that was modeled through
the use of simulation will be shown. The final goal is to show the view inside the extruder through the model so that we can use simulation
to better understand the process, troubleshoot and try different polymers in the extruder before running them to be able to know what to
expect beforehand.
