As an example azdel a glass reinforced thermoplastic composite made with continuous glass mat is produced using an extrusion lamination operation film continuous random orientation glass mat and molten resin are combined in a lamination process using a sandvik double belted.
Wet lamination process.
Drawing 1 illustrates the concept of the wet lamination method described.
Laminating machinery can be classified according to the type of bonding agent used to produce the laminates.
Lamination is the technique process of manufacturing a material in multiple layers so that the composite material achieves improved strength stability sound insulation appearance or other properties from the use of the differing materials such as plastic a laminate is a permanently assembled object created using heat pressure welding or gluing.
The laminate then passes through the chilled nip of the combiner roll cooling the plastic layer which solidifies.
Once the wet bonding process is applied to each substrate the two substrates will then be combined prior to passing through an.
The hot melt process is used for high speed lamination since there is no need for a drying stage.
It is commonly used to produce a paper aluminum foil laminate that is widely used in flexible packaging.
Wet lamination showed to have the following advantages.
The older dry lamination process common in the offset printing industry or the newer more versatile wet lamination process which is dominant in the flexo label industry.
Wet bond lamination is a laminating process used to laminate two substrates one of which is porous such as paper.
For example a foil and paper substrate lamination may be accomplished through a wet bonding process.
The wet lamination process can be used for the cost effective manufacture of components in simple shapes.
Another lamination process uses a lamination press after materials are combined in a thicker structure than film.
Cold foil printing also known as cold foil stamping is a modern method of printing metallic foil on a substrate in order to enhance the aesthetic of the final product cold foil printing can be done two ways.
Laminating process laminating is the process through wh laminating process.
When only the two layers are involved the process is known as extrusion coating.
The substrates making up the webs may consist of films papers or aluminum foils.
Impossible to trap air bubbles.
However the material properties in the wet lamination process are not as good as with other processes.
The large proportion of manual production requires well trained specialists and careful quality control.
Where the bonding agent is still in a liquid state when the webs are joined together.
Particles and other surface contaminants are washed away by water.
