Presses Type E

Models: P 200 E, P 200 E air P 300 E, P 300 E air P 400 E

Laboratory platen presses are used in the manufacturing of polymer sheets for optical and physical tests of moulded forms. Depending on the requirements, these machines are also suitable for composites, components or for embossing. The wide variety of products allows Collin to deliver the right solution for each application.

The Type E series platen presses is the entrance version among Collin presses. As a 4-column design with a fixed, upper counter-plate and moveable, lower platen, Collin presses cover an enormous range of pressure. The big distance between the columns creates ideal opportunities to act within the interior of the press.

  • Presses P 200 E to P 400 E: single-stage hydraulic with double-acting hydraulic cylinder
  • Exception Press Type Air: the Collin pneumatic press for lowest pressure and very high accuracy
  • Press materials: Processing of polymer materials, ceramic materials, composites and further specialities within a   temperature range from 20°C to 300°C

Presses Type S

Models: P 200 S, P 300 S, P 400 S, P 500 S

Laboratory platen presses are used in the manufacturing of polymer sheets for optical and physical tests of moulded forms.

Several extruders in an elevated position discharge into a multi-layer die. The hose is guided downwards into a water cooling ring. After that, it is laid flat, dried if necessary, positioned or cut and then wound on rolls.

Advantages of the procedure 

  • From the production of the hose up to the welding of the bag,  the inner surface of the bag remains clean.
  • By shock-cooling, the clearness of the PP compound is reached.
  • A material with even orientation is produced.
  • By selecting suitable materials for the different layers, desired characteristics are optimally  adapted to the requirements.
