No more manual power needed to pump up the sheetpress as it is started with a button, it automatically starts when the plastic gets molten and the pressure goes down. You can set the pressure you need it work within the range. Feel free to contact me, can send you videos of how it is working.
We are a factory with over 100 machines production experience (V3 and v4 versions), lots of pictures and videos, feel free to send me a message. We use only reliable mechanical parts and components to make our machines. We also make manual sheetpresses
Also see the video of the machine running.
