1. Set the workpiece fixed to a jig on the alignment table

2. Alignment with the vision system

3. The transfer lifts the jig by suction pads, and conveys the jig to the laminator

Bonding without bubbles under high vacuum and pressure

This machine bonds various types of films onto double surface glass, LCD panels, touch screens, etc.

Capable of bonding curved surface and/or uneven surface.

It realizes high adhesiveness without bubbles by producing vacuum condition before applying pressure in the vacuum chamber. From 0 up to 10atm can be applied, which eliminates the need for post-process such as autoclaving.

Demonstration available at Matsuyama factory. Contact us from here.

NPC’s vacuum chamber bonding

①Diaphragm sheet bonding	With heat resistant rubber sheet, adhere films to workpieces with irregular form and/or uneven surface. Maximum pressure: 7atm
②Flat plate bonding (with a heater on the upper plate)	Capable of uniform bonding of double surface glass, etc. Reduces winding of the edges. Maximum pressure: 3atm
③NPC's originally developped bonding method (Patent pending)	Capable of applying pressure up to 10atm. Suitable for workpieces with uneven surface and/or workpieces that require high pressure.
