Polymer Sheet Prototyping Hot Press Devices
Application:
* Production of rubber sheets according to the standard with specified temperature, strength and thickness conditions to perform various destructive and non-destructive tests.
* Helps design with more accurate calculations according to simulated working conditions
* Research and development in the field of rubber materials
* Quality control and production
Product Introduction:
The 50 ton press, which is a hot press with a thermal zone, is a professional and suitable machine for making rubber sheets. The machine is equipped with large plates equipped with special heaters between the plates to bring the temperature of the mold to the required operating temperature with the least energy. Inside it is a hydraulic jack with an electronic pressure gauge to move the bottom plate. In this process, the power is transferred to the plates by a spherical joint (in the form of self-alignment) and the necessary force is uniformly distributed to the press. Finally, a completely uniform sheet with uniform thickness is produced.
The method of working with this device is very simple and the control and definition of the test is done by a HMI touch screen that commands a PLC. Mold temperature, press force, preload time, number of ventilations and baking time, all can be programmed by definition on the touch screen. After determining the control parameters, the compound is poured on the corresponding mold and after pressing the start key, all the baking steps are done automatically. After the cooking time is over, the machine gives an alarm and the cooking process is stopped and the press is opened.
