Composite forming shoulders are the only ones that for hundred percent ensure smooth film move.
High exactness of functional surface of shoulder that is not possible to reach by common ways of production)
Packaging film fit perfectly on shoulder
Packaging material is not damaged during forming on shoulder
Surface of shoulder is made from very hard, solid and wear resistant shift
Availability of any real shoulder shape – various cuttings, inclination angles or lengthwise overlaps
Shoulder surface is smooth or mapped (for wet environment)
We offer making of composite shoulders of various shape to other companies including producers of packaging machines as well.
Production technology of composite forming shoulders enables uncontested most-perfect shape of collar, because shape of functional shoulder surface exactly correspond to shape of packaging film at the moment of passing from flat film to hose.
Composite design of shoulders leans on the fact that shoulder is made from materials of very different characteristics, whose proper combination leads to reaching of optimum qualities, required for use of shoulder. For example, surface of shoulder is made from very hard, solid and wear resistant shift while body of shoulder is produced from soft material with carrying function only.
