Vacuum Bonding Machine
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.

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.
