Outline:
Softal’s “Aldyne” atmospheric linear plasma surface treatment system generates plasma discharge in a mixed gas atmosphere having a base of nitrogen gas to bond the added gas molecules to the substrate surface. As such, high polarity, functional amide and amino groups are generated.
In addition, using the nature of these groups to readily form covalent bonds with the functional groups in the coating, it is possible to increase the strength of bonding between the substrate and coating.

Characteristics:
Achieves a high adhesion unobtainable with corona treatment
Adhesion is long-term with no change over time

Corona Surface Treatment System
Summary:
Softal’s corona treatment system is composed of a high-efficiency generator and a durable, compact treatment station. The system improves the adhesion of printing ink, adhesives, lacquer, and various coatings to a wide range of substrate surfaces.

Characteristics:
Generator
High-efficiency, stable output based on resonance circuit technology
Simple operation via a touch panel
Rapid normal return via a self-diagnostic function
Interface function with the production line
Output is possible over a wide range from 1 kW to 60 kW

Treatment Station
High-efficiency discharge via a specially designed electrode
Realizes space reduction via a compact design
High-efficiency ozone exhaust
Simple calibration and operational functions
High stability via a fine interlock function
Wide range of models for treatment widths of 200 mm to 10 m

Characteristics:
By bringing together our engineering staff with more than 60 years of experience in metal processing and high-precision grinding, with our dedicated die coating engineers with their know-how on die design, we have been highly recognized for out ability to meet the difficult needs of our customers.

-Precision Performance
Material: SUS316L
Slit Deviation: within 2 μm/1,700 mm length
Tip Surface Straightness: within 2 μm/1,700 mm length
Tip Surface Roughness: Rz 0.130 (realized via an ultra-precise grinding lathe and our proprietary whetstone)

-The material for our dies can either be magnetic (SUS630, etc.) or nonmagnetic (SUS316, etc.)
-Our dedicated die coating engineers also handle proposals for die channel structures and design
-We also overhaul, repair damage to, and alter coating dies (slot dies) manufactured by other makers

Characteristics:
-It is possible to precisely measure the die slit by simply inserting the gauge into the slit and reading the gradations
-One gradation is 1 μｍ!
-The special resin used as the gauge material prevents the gauge from damaging the part to be measured while having wear resistance (patented)
-We can customize the gauge for all needs, from precision level to measurement range, depending on the purpose and application
-The cost is far less than that for image measurement systems integrated with a CCD camera (standard price, 200,000 JPY and up).

In addition to our calender forming testing facilities, which have been used by many of our customers, we have newly installed a testing research facility that allows for a range of rolling and roll press applications.
We hope you take advantage of these in pursuing product development and production.

Applications:
-Secondary battery material roll press
-Room temperature/warm rolling (press)
-Reverse rolling (press)
-Skin pass rolling
-Calendering
-Laminating/coating
-Friction rolling
-Others

Facility Configuration:
Unwinder→pre-guide system→rolling machine (rolling machine/press roll)→post-guide system→rewinder

Specifications:
-Material Width: 700 mm (max.)
-Roll Size: φ500×L800
-Rolling Force: 1,000 kN (max.)
-Rolling Speed: 2-20 m/min

Today, the calender forming process is being reconsidered for the production of advanced films and sheets. We produce the entire calender machine, including the rollers, and have already delivered several such machines.

Calender Forming Method Functions and Characteristics:
-High forming speed
-Forming can be observed by sight, and operability is good
-Color change is simple and the machine can be used for multi-product manufacture
-Able to form at relatively low resin temperatures
-Width and thickness ranges for films are wide and control precision is high
-Profile control is simple, and film uniformity and dimensional precision are high
-The number of filler types and mixing ranges are large, and forming over a wide range of plasticities and viscosities is possible
