■ Features & Functions
Setting of appropriate condition is easy.
It is possible to create appropriate conditions for removing air bubbles after sticking a polarizing plate in the LCD manufacturing process by setting temperature, pressure, and time in combination.
Improving the adhesion strength between polarizing plate and cell
It is possible to increase the adhesion strength between the polarizing plate and cell after sticking the polarizing plate by applying heat and pressure.
Each setting is easy.
As the high precision digital input system is employed for setting temperature, pressure, time, etc. , settings are easy.
(PTU-305VⅢ can set only temperature and time.)
High precision control system
The temperature control system is a PID control / SSR drive method, and the pressure control system is a ON / OFF control and solenoid valve open / close system or motor-driven valve open / close system, enabling high precision control.
Equipped with various safety devices including interlock mechanism
The door clamping method employs a clutch system driven by gears with secure interlock mechanism. (PTU-305VIII uses the eye bolts for clamping) The chamber is made of stainless steel and the over-temperature prevention device, over-pressure prevention device, pressure safety valve, etc. are installed.
Applicable to the heated and pressurized environments
This equipment is applicable not only to the removal of air bubbles in the liquid crystal display but also to the heated and pressurized environments.
A cycle time is shortened.
A warm-up function enables quick rise time and shorten the cycle time.
