Usage Procedure

1. Preparation of the Material: Position the material to be processed on the press tables and align it correctly.
2. Parameter Setting: Adjust the closing force and table stroke according to the specifications of the operation. Use the control to set the approach and working speed.
3. Pressing Operation: Start the pressing process via the control panel, monitoring the operations to ensure that the set parameters are respected.
4. Checking the Part: After the operation, inspect the part to ensure the quality and precision of the workmanship.

Compatible Accessories

• Additional Molds and Dies: To adapt to different geometries and materials.
• Cooling System: To maintain optimal operating temperature during extended use.
• Safety Devices: Updates and adjustments to ensure compliance with accident prevention regulations.

Mathematical Formulas for Optimal Use

• Pressing Force (F): Calculated as: F=P×AF = P \times A $F$ $=$ $P$ $\times$ $A$ Where:

  • PP $P$ is the applied pressure in tons.
  • AA $A$ is the contact surface area in mm².

• Working Speed ​​(v): Determined by distance and cycle time: v=DTv = \frac{D}{T} $v$ $=$ T D ​Where

  • DD $D$ is the distance traveled in mm.
  • TT $T$ is the time taken in minutes.
