MACHINERY | TECHNOLOGY RECYCLING Closing the loop on multi-layer film
Coperion has devel- oped a closed-loop concept for the production of flexible multi-layer film. Recycling multi- layer film is often complicated, due to the presence of multiple materials. However, Coperion says it has developed a closed-loop approach that can repro- cess and re-use up to 100% of multi-layer film production waste.

throughput) help to achieve high product quality. Following homogenisa-
tion, the recycled material is added back into the multi-layer film produc- tion process – with a high proportion of added
shredded, then fed into a ZSK extruder via pneumatic conveying and feeding. There, the material is homogenised and devolatil- ised in a co-rotating ZSK Mc18 twin screw extruder.
Within the extruder, disper- sion and devolatilisation performance, gentle product handling and good mixing (even at high
TESTING
Flexible force testing with multiple options
Ametek has introduced its Chatillon TCM series of flexible motorised test machines. The TCM series consists of two force testers, offering fast and effective force testing up to 350lbf (1500N). TCM100 is suitable for low capacity testing up to 100lbf
Pre-shredder combines looks with ergonomics
Vecoplan’s new VEZ 3200 pre-shredder is one of this year’s winners of a Red Dot award for product design. It was developed to produce refuse-derived fuel (RDF).
Vecoplan focused on a contemporary appearance when creating the VEZ – and took on an industrial design company as a partner – but said it was not “just about colour and shape”. “For us, the design was not all about appearance:
ergonomics was also an important factor,” said Werner Berens, CEO of Vecoplan. He said that the design influences the machine con- struction – making the shredder easier to handle for operators. The company has already sold around 15 machines worldwide. �

(500N), while TCM350 can test samples at a capacity up to 350lbf (1500N). Both feature a standard crosshead travel of 406mm (16in) and are available in extended editions with a crosshead travel of 812mm (32in). A throat depth at a full 100mm (3.9in) enables
the operator to perform force tests including tension, compression, bending, peeling, adhesion, insertion and extraction on samples up to 200mm (7.8in). This leaves the operator with a wide variety of testing options at a large working area while keeping a compact footprint. Coupling the force testers with the digital
Chatillon DF Series force gauges offers a load accuracy that exceeds 0.1% full scale as well as added benefits such as drive to limit. Chatillon ForceTest software can be added, to enable seamless serial data communication from the force tester to a computer. �

recycling system of this type of an unnamed customer. �
