Mühlen FLEX R4-330B — 4-Roller A3 Laminating Machine with Internal Heating
Who Is It For?
The Mühlen FLEX R4-330B is a professional A3 laminating machine for offices, print shops, schools, photographers and sign workshops that coat documents, photos and cards every day. Four internally heated rollers and hot and cold modes give consistent, smooth results, while its 480x211x115 mm footprint and 8.3 kg net weight keep it manageable on a desk. It is a step up for users who regularly need A3 work and thicker material than entry-level 2-roller A4 models handle.
Key Features and What They Do
- 4 internally heated rollers: Heat is delivered from inside the rollers, so the film bonds evenly to the document with less risk of bubbles or haze.
- Digital temperature control from 0~145°C: Fine-tune heat to the film thickness, or use the 100°C shortcut key to reach a common setting with one touch.
- 80~250 micron film, material up to 1 mm: Handles anything from a thin protective layer to stiff card coatings.
- 325 mm entry for A3 to A6: Posters and larger sheets as well as small cards pass through the same machine.
- Up to 500 mm/min with automatic speed: Combined with a 2~3 min warm-up, jobs can start quickly and finish without long waits.
- Reverse rewind and anti-jam: A jammed document can be wound back, and an automatic shut-off after 2 hours saves energy if the machine is left on.

Usage and Care Tips
Set a temperature between 0 and 145°C to suit your film and let the 2~3 minute warm-up finish before feeding. Once the rollers have cooled after use, wipe the surface with a dry cloth to prevent film residue from building up. The 550 Watt machine runs from a standard socket, and if you forget to switch it off, the automatic shut-off ends operation after 2 hours. The machine comes with a 24 months warranty.
