Highly flexible extrusion downstream equipment for flat films & plates

Collin provides the customers with coextrusion lines for the simulation of composites of all common polymers. For that purpose, feedblock systems for 2 to 9 layers are the standard tool, furthermore, multi-layer dies (multimanifold) for 2 or 3 layers allow the coextrusion of polymers with different viscosities. The use of these die systems (also in combination) allows the simulation of all combinations and procedures common in the production of multi-layer films. With our sophisticated concept of the height-adjustment for extruders, adapters, the moveable die frame and the electrical control, we create a flexible adaptation to all tasks.

Collin extrusion downstream equipment for flat films and plates is suitable for an extremely flexible use. Thus, our customers are in the position to produce films and plates with a thickness of 20 µm to 5000 µm. In case of large machines, the maximum width of the rolls is 900 mm. The downstream equipment is equipped with an own control system but, with the superordinated software module FECON, it can also be combined into complex multi-layer lines for pilot production. A great variety of accessories such as additional unwinding and winding stations and modules such as corona treatment or temper stations allow the development and production of totally new composite materials.

The Chill Roll resp. calender units consist of three swivel-mounted, temperature-controlled rolls. With a width of 100 mm to 900 mm, in production, they cover a thickness range of 20 µm to 5000 µm and can flexibly be used as cast, calender but also laminating units. As standard, a line speed of up to 50 m/min. is possible. On demand, we also realise higher speeds. Our flat films and platen lines are outstandingly suitable for production-related development of e. g. optical films, the production of niche products and small series.
