Ultra Thin Metal Foil with Plating
Cutting edge plating thin metals of roll to roll type for smart phone, LCD, OLED, PTC, EMI, RFID, battery, fine pattern printed circuit, steel pipe and so on.
- Description
-
To give the physical and chemical properties demanded by customers to metal foils used in electric and electronic products, we are plating mono metal or two or more types of metals and electronically plating alloys of various thicknesses in 0.1-5㎛ to 10-300㎛ thickness metal foils in continuous processing lines. Also, our nodular treatment technology has advantages of reinforcing the adhesion with polymer based on the size and shape of metallic nano powder and improving the electric property.
Feature
Roll to roll Type
Roll Width : +1700 Speed : Max. 100m/min
Coating method : Gravure, Micro Gravure, Comma ( 3 types )
Dryer : 4m x 5 zone ( Max. Pemp 180°C
Specification
Surface treatment can be done on double or single sides, and plating is performed on various raw materials using different ingredients.Single PlatingSurface treating single plating with electrolysis plating on various metallic foils such as copper and STS.
Products made from this process can substitute expensive metals or rare metals, be given electromagnetic properties, and prevent corrosion of product.
Also, each side is differently plated. In particular, the shiny side and matte side show unique appearances.
Of the above, matte side is produced by applying metallic nodular technology in nano size to maximize adhesion with polymer (PE, PI, PET), and the opposite side is plated in uniform and clean appearance of final product..jpg "3(0).jpg")

Single plating applications
Alloy Plating
Alloy plating can be used as ingredient for magnetic or magnetic resistance, and offers better qualities than simple plating.
For example, binary alloy plating such as tin and tin/zinc has good elongation property and increases lubrication and abrasion resistance, hence providing an important role of increasing dip drawing and plastic forming property during plating on general steel.
For example, binary alloy plating such as tin and tin/zinc has good elongation property and increases lubrication and abrasion resistance, hence providing an important role of increasing dip drawing and plastic forming property during plating on general steel.
We can supply multiple alloy foils in thicknesses from hundreds of nano meters to tens of micrometers onto various thin foils (copper foil or various films according to the composition and conditions demanded by customers.

Multiple plating application area
Black Plating
- Developed nodule plating technology and corrosion resistant plating technology using rolled copper foil
- Nodule is formed on the matte side, maximizing the surface area for higher adhesion strength whereas the shiny side is plated for heat resistance and corrosion resistance
Characteristics of plated foil
- Maximized adhesion strength through hundreds of nano sized micro nodules
- Superior heat resistance property through increasing surface area
- Corrosion resistance and heat resistance of product through post-process plating
