Shannon HR50 Plastic Bending Machine
Our Shannon HR50 Plastic Bending Machine was generously financed by Sparebankstiftelsen DNB
Shannon HR50 uses heating wire to make plastics malleable. It is a strip heater thus its used to bend plastics in a straight line. We intended to use this machine as a accessory to our laser cutter

- The plastic bending machine is never to be left unsupervised during operation.
- Do not move the cutting head while the machine is turned on.
- Do not move the machine during operation.
- Power off the machine when you are done.
- If your material turns dark, emits smoke or starts to buble. Remove your material at once!
- Only use this machine with thermoplastics such as:
- Acrylic PMMA
- Polystyrene
- Polycarbonate
- PETG
- PET
- ABS
Standard Operating Procedure
- Figure out the temperature required to bend your plastic.
- Set appropriate temperature.
- Adjust the backstop so the bend line lines up with the heating wire.
- Once the press has reached the desired temperature, position the plastic on the work area.
- Wait until the plastic becomes malleable.
- Bend your thing.
- Turn off the machine and tidy up after you.
