Working pressure

1. Maximum pressure 150 tons, pressure adjustable from 1 to 150 tons. Main cylinder pressing force controlled by Gefran pressure sensor. Pressure of all oil cylinders directly displayed on the operation screen; can be freely adjusted automatically according to product needs.

2. Bidirectional pressure pressing. Upper and lower cylinders are the same size (note: text inconsistency, says 16 tons here but elsewhere says 150 tons; likely a typo. Should be 150 tons as per model). During pressing, both upper and lower punches are driven by oil cylinders, forming bidirectional pressing for uniform product density. Pressing steps: Feeding box advances -> Lower punch descends to form cavity -> Feeding box moves to feed material into die cavity and retracts, completing feeding -> Lower punch descends 3mm to ensure all material is within the die -> Upper punch fast down -> Slow down for die closing -> Pre-press -> Lower punch moves upward to form pressure -> Upper and lower punches press bidirectionally -> Upper punch reduces pressure, pressure-maintained ejection (optional; can also be non-pressure-maintained ejection based on product needs; pressure-maintaining force is adjustable, automatically adjusted upon input on the touch screen) -> Pressure release -> Lower punch moves up -> Upper punch returns -> After product ejection, leaves pressing area, feeding box prepares for next feeding -> Enters next automatic cycle.
Main cylinder and lower cylinder use high-precision displacement sensors for signal conversion; travel of upper/lower punches and die floating plate directly displayed on screen.
Upper punch forming position, die feeding position, under-filling position, and die ejection position controlled by two-axis CNC positioning system (digital hydraulic motion controller, high-precision displacement sensor, optionally equipped with digital oil chiller or water chiller for temperature control).
1. Equipment uses PLC, touch screen, and related sensors for automated control functions.
