There are three elements of the vulcanized product, one is pressure. Therefore, ensuring the normal pressure of the rubber compression molding machine, is the key to producing good silicone&rubber products. How to judge whether the pressure is normal and how to choose the right pressure according to the mold is the knowledge that a skilled worker should master.
How to choose the pressure according to the mold: the normal operating pressure of the machine is 20bar-200bar, and the pressure is determined according to the size of the mold; If the mold area occupies about 50% of the machine, the vulcanizing pressure should be selected at 100bar-120bar
How to determine if the pressure is correct: Through setting the HMI and adjusting the hydraulic pressure valve, see if the pointer of the pressure gauge reaches the pressure as set. Normally it is tested with four pressure values of 50bar, 100bar, 150bar and 200bar. This pressure list is usually checked when the machine delivery from factory. If pressure re-adjustment is required, please contact our professional service for help.
The factors that affect whether the hydraulic pressure value is stable or not :
- Is the pressure sensor correct?
- Is the amplifier board current adjustment appropriate?
- Is the hydraulic pressure valve adjustment correct and the pump running normally?
