The sheet press is utilized for bending plastic sheets, solid surfaces, or extruded beams. The process is straightforward but may need preparation for optimal results. Follow these steps for effective use:
Tools Required:
- Sheet press
- Mould
- Clamps

To achieve consistent results, use a mold for bending. For larger projects, sharp corners, or intricate shapes, consider a counter mold to ensure proper shaping. Plan clamp placement to ensure sufficient space for secure attachment.

The next step is to determine temperature and timing.
Temperature varies based on plastic type and thickness. Check if the plastic bends sufficiently or experiment with smaller pieces before using larger sheets.
Below are some settings we have utilized.

Place the plastic on a 1/8 inch (3 mm) MDF sheet to prevent sticking to the press. Position the sheet and adjust the bottom bed upwards, leaving a 3/8 inch (1 cm) gap.
You can also bend sheets larger than the press, provided the bent section fits within it (e.g., a 6.6 x 3.3 ft (2 x 1 m) sheet).

Once the sheets are adequately heated, promptly transfer them to the mold, as they cool rapidly. Ensure all clamps are accessible. It is advisable to have a second person assist with this task.
