Slot die has heads that uniformly apply coatings to substrates. For providing coating with no defects, the die should be positioned in the ideal geometry between the substrate and die lips. This can be accomplished by following some techniques:
- Wipe/Contact- The phenomenon in which the material is applied directly to the substrate supported by the backup roll is called a direct coating. When the material is applied to a metering roll and then transferred to the substrate it is called the indirect coating. It can achieve lower coating thickness in replacement of the direct coating methods.
- Curtain- This coating allows the increase in speed of production. In this coating, the material is directly applied to the substrate from distance. The die is positioned above the substrate to allow the fluid to coat thin and fast.
- Tensioned Web Over slot die coating- Tensioned Web Over slot die coating is also called as free span coating. Tensioned Web Over slot die coating apply the material directly to the substrate without the help of a backup roll. This method is used with solutions so that it can adhere to a substrate.
The Roll-to-Roll Printing Market for flexible devices is expected to reach USD 35.79 billion by 2022, at a CAGR of 11.04% between 2016 and 2022.
Roll-to-roll printing is a technology used for manufacturing flexible devices, where the materials are printed in the same fashion as newspapers are.
Owing to the ability of this printing technology to carry out the production of flexible and large area electronic devices in large quantities and at cheaper costs, the roll-to-roll printing market for flexible devices is gaining substantial importance.Konica Minolta Inc. (Japan) and Sumitomo Electric Industries Inc. (Japan) are two of the key players in the roll-to-roll printing market for flexible devices.
Konica Minolta provides inkjet print heads and OLED lighting devices which are crucial in the global flexible electronics market.
The company’s sales, marketing, and distribution channels are spread over 150 countries, including presence in key geographic regions such as North America, Europe, and Asia-Pacific, especially China and Japan, for revenue generation.Get PDF Brochure: https://www.marketsandmarkets.com/requestsampleNew.asp?id=13173263The company introduced the QWP film, an obliquely oriented film which enables organic light-emitting diode (OLED) displays and LCDs to be viewed without any chromatic change in the image displayed, even when viewed through polarized sunglasses.
Sumitomo Electric Industries Inc. (Japan), along with its subsidiary Sumitomo Electric Printed Circuits Inc. (Japan), manufactures a range of flexible printed electronic circuits which are used in a wide range of applications including wearable devices, medical measuring equipment, automobiles, hard disk drives, liquid crystal displays, touch panels, and LED light fixtures.
