Laminating technology that creates high added value and new functions



Example of laminating



We can help you add value to parts and products using our laminating technology.

With our automatic laminating machine and vacuum automatic laminating machine, it is possible to handle a wide variety of flat panel displays.
We have a track record of supporting high-precision polarizing plate laminate to panels, film laminate to glass, direct laminating (OCA method / OCR method), and film-to-film laminating.
We support not only laminating of flat plates, but also laminating to 2.5D and 3D shapes. Please feel free to contact us as the restrictions will change greatly depending on the shape.

【Reference】
  • We will finish the products prototyped by our company, such as direct bonding, so that they can be exhibited at the exhibition.
  • We will propose a method that matches the demo machine you requested, such as creating a housing using 3D printer modeling / creating a housing using sheet metal.
  • Boards and FPCs can also be created / procured if the circuit is provided by the customer.

Flow until creation


① Meeting with the customer for specifications (get the following information)

  • Schematic image (ponchi-e)
  • Storage parts (LCD, board, battery, etc.)
  • Drawing or actual item, etc.
  • Information on desired quantity / desired delivery date

② We will study the concept, create and submit the concept.

③ Structure determination / specification fix (by customer approval)

④ Manufacture (creation of parts drawings, procurement of parts, assembly), delivery



* In order to drive a display with a commercially available drive board, a large number of boards and harnesses connecting them are often required as shown in the example shown in the figure. Since few commercial products have all the functions to control the display, they are often used in combination with a custom-made board to achieve this condition.
