Our 0.5 Ton Hot Press kit is extremely simple to operate and install. An air-operated cylinder with a directional control valve and pressure regulator are at the heart of this system.
To allow operation in a high temperature furnace, a water-cooled cold rod is attached to the cylinder and is fed into the chamber through vacuum tight metallic bellows. These bellows allow the furnace physical test rod to travel while maintaining a vacuum seal. The bellows eliminate the need of a sliding vacuum seal which tends to be unreliable and prone to wear.
A hot rod is threaded into the cold rod and is easily capable of withstanding system pressure at the maximum furnace temperature. An insulator is added between the hot rod and water-cooled rod to minimize heat losses and interference in the hot zone temperature uniformity.
The accuracy of this system is determined by the accuracy of the air regulator. A 0.001″ step-dial indicator allows observation of the travel amount and can be used to determine sample compression.
Mounting this kit is also extremely easy as it mounts directly onto the chamber and thus requires no mounting frame.
* Please note this kit can only be mounted on select furnace systems as an add-on. For complete turn key hot press systems, please see our hot press furnaces
