Electrically Heated Platens
Specac’s Atlas Heated Platens have been designed for use with all Specac Atlas-series Hydraulic Presses to provide heated pressing surface up to 300ºC temperature, with a load bearing capacity up to 15 tons. The platens are easily installed into Specac presses by replacing the upper pressing face bolster fixing with the top heated platen and placing the lower heated platen over the lower pressing face of the press.
A digital automatic temperature controller with a stability of ±1°C is provided for control of the platens, and the lower heated platen is fitted with a permanent thermocouple that monitors the temperature close to the pressing surface of the platens. The support blocks of the platens that connect to the press, are water cooled to isolate the press from any direct heating effect of the platens and to allow for efficient heating and cooling cycles of operation. An inline flow safety cut out device is incorporated into the water flow tubing to switch off power to the platens if the water supply is cut or interrupted. PVC tubing and flow connectors are supplied with the heated platens for water cooling.
The heated platens and press products are also designed to be used with Specac’s Constant Thickness Film Maker accessory (GS15640) for the preparation of thin films of polymers and plastic materials at a diameter of 29mm. However, the heated platens can be used alone in a press, without the film maker accessory, if larger diameter films are required for pressing.
