Multi-station thermoforming machines: c.600 and c.800

The multi-station thermoforming machines of the c600/c800 series are used in applications where the most important criterion is high throughput, high production volumes and complex moulded part shapes. Separating the individual phases of part production (film heating, part forming, part punching and part stacking) into separate stations results in a significant increase in productivity compared to single-station machines.

It also allows the introduction of additional intermediate operations (e.g. punching of holes, insertion of absorbent pads, etc.) as well as supplementing the process with additional pre- and post-production operations such as film pre-heating (recommended for PP production), stacking robot (allowing A-B stacking), lid stacker, sleevers, cartoners, palletising robots, etc.

These machines are best suited for the production of packaging from materials such as PET (aPET, rPET, cPET), PP, PS, PE, PLA and all thermoformable rigid films.

High production capacity;
Ability to produce moulded parts with complex shapes;
Production from a wide range of materials, including multilayer, barrier and foam;
Ability to adapt the machine to produce cPET packaging;
Wide possibilities for initial machine configuration and subsequent expansion.

Thermoforming is a key technology in plastic packaging production, offering efficiency, flexibility and wide adaptability to different market needs. The potential of this technology in the context of increasing automation and the drive towards sustainability is significant, making it extremely valuable in the modern packaging industry.

Our machines are designed and manufactured with 24/7 operation and many years of service in mind. All a.80 (formerly TFA-8060) and c.600/800 (formerly CF-600/CF-800) series thermoforming machines manufactured by us are in continuous operation*, mostly with their original Purchasers. *status as of January 2024).

One of our priorities when designing and manufacturing our machines is to ensure that the costs associated with their operation are as low as possible. This applies in particular to electricity consumption, minimising service costs or keeping production waste to a minimum. To this end, we incorporate a number of technical solutions and technologies to ensure this effect, such as:

recuperation (recovery) of kinetic braking energy by servo drives, including:
return of excess stored energy to the grid;
specially designed motion trajectories of the servo drives reducing energy consumption;

internal insulation of heating elements and external insulation of heating zones to minimise heat dissipation;
design of components exposed to wear and tear (e.g. chain guides) in materials with increased resistance;
operating algorithms and a range of mechanical solutions to ensure that production waste is minimised.
