Key Features
- Produces recycled plastic sheets up to 60mm thick from shredded flake
- Delivers 20 tons of hydraulic pressure for reliable, even compression
- Interlockable plates — combine to press full sheets up to 1150 × 2300 mm
- Hydraulic via pneumatic drive or standard hydraulic cylinder
- Safe, ergonomic mould handling with guided rails
- Sequential heating — staggers plate activation to stay within power supply limits
- Adaptive pressure — fully configurable via the built-in web interface
- Visual and audible feedback at every stage of the cycle
- Advanced web interface for precise pressure, temperature, and event control — view documentation
- Open hardware — licensed under CERN OHL v2
