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.

Various laminating technologies

Direct laminating

Laminating of optical materials between rigid bodies such as displays and cover glass is called direct laminating (optimal laminating).
It supports a variety of sizes, from small 1-inch displays to TV sizes.

Direct laminating compatible size
・ OCA (up to 47 inches)
・ OCR (up to 12 inches)

Film laminating


In addition to laminating polarizing plates, various functional films are also laminated.
With a large number of owned machines, it can be used for a wide range of applications such as laminating large films and high-precision alignment.

Flat / curved surface laminating technology

In addition to flat plates, we also accept lamination on curved surfaces.

Laminating machines


The highly versatile laminating machines make it possible to flexibly respond to customer prototype specifications.
In order to realize highly difficult laminating, we will realize laminating from abundant experience such as equipment modification and process construction.

High-precision laminating machine



Basic specifications
  • Corresponding panel size: 4 to 13.3 inches
  • laminating accuracy: ± 0.05 mm
  • Work holding with a holding sheet that does not allow air bubbles to enter the front and rear ends

Semi-automatic sheet-fed laminating machine (high precision type)



Basic specifications
  • Telephoto type with auto-alignment function
  • Laminating accuracy: ± 0.05
  • Corresponding size: W500 × L600 × T (total height) 15mm
  • Weight: up to 3 kg
  • Please use it for bonding various thin materials such as touch panels, cover glass, protective films, etc.
  • If the curvature is loose, 2.5D (kamaboko type) support is also possible.
  • Conditions vary depending on the object, so please contact us each time.

Remarks: Ultra-high precision laminating machine = alignment mark can be recognized / High precision laminating machine = edge detection


Features: Compatible with 1-29 inches, maximum accuracy ± 25μ, sensor film, OCA, decorative film possible


Technical issues related to laminating and trial production consultation

We will help you solve the problems of laminating technology.

1) Prototype support, trial prototype
The panel and film laminating process supports. Trial production from a single panel.
Please contact us for the difficult prototype requirements that other companies have refused. We will try the prototype after considering the machine and process.

2) Consultation advice on technology and manufacturing process
We will build and realize the optimum laminating process based on many prototype results and experience values for highly difficult laminating such as high precision, various materials, and curved surfaces.
We also provide feedback on prototype results upon request. Please contact us if you have any information that requires feedback on the evaluation of the prototype.
