units. The second unit can be used to apply a second material in a different colour, with a special tactile quality, or to create a hard/soft combination. At the show, however, the second discharge unit will apply a water-soluble support structure during production of a key fob with a moveable ball joint in ABS. The support structure is removed post-build in a water bath. Injection moulding applications include a high
such as bed slat supports. The company will also be showing examples of the
biodegradable and compostable single–serve capsule it has designed together with Italian packaging machinery manufacturer ICA and compression moulding equip- ment supplier Sacmi. The capsules are produced in an Apinat Bio grade at a rate of up to 600 per minute on a Sacmi CCM24 compression machine. Apinat Bio materials are available in hard (35-78
Shore D) and soft (55-90 Shore A) versions. They offer easy moulding and high flexibility and are suitable for over-moulding applications. ❙

Arburg Hall 22 Stand C81/D82
Arburg will show a broad range of advanced injection moulding applications at Plast but centre of attention is likely to be its Freeformer additive manufacturing (3D print) system, which is being shown in Italy for the first time. Fully-functional additive manufactured plastic parts
Below: A selection of parts produced on Arburg’s Freeformer additive manufacturing system
can be produced using standard granular materials on the Freeformer, which employs Arburg’s patented “Plastic Freeforming” process. This melts the polymer granules in a plasticising cylinder then applies molten droplets layer-by-layer onto a moving part carrier via a stationary discharge nozzle to create a 3D component direct from a CAD model. High-frequency piezo technology is used to deposit the droplets at application cycles ranging from 60 to 200 Hertz. Freeformer systems are equipped with two discharge
performance hybrid Allrounder 720H packaging specification machine producing PC 1881 screw caps for CSD applications on a 72-cavity mould from Z-Moulds. The system will run at a cycle time of around 3.5s and will processes more than 160kg of HDPE an hour. It includes Motan material handling, Nova Frigo closure cooling and Intravis optical inspection. Multi-component applications include production of a ballpoint pen cap in a combination of PP and TPE on an 8+8 cavity mould from Fila. The application will run on a 160 tonne Allrounder 520S machine with two injection units running a 20s cycle. ❙

Boy Hall 11 Stand B01/Hall 22 Stand B36 Boy will be demonstrating five machines at the show with its local partner ST.A.TE Technologies, focusing on thermoplastic processing in Hall 11 and elastomer production in Hall 22. Thermoplastic exhibits include a 35 tonne Boy 35E
producing thin walled business cards at high fill rates using the company’s differential injection units. A vertical 35 tonne Boy 35E VV will be manufacturing hexagonal key wrenches with an overmoulded plastic handle, while a 10 tonne Boy XS will show automated production of protective electronic caps on an 8-cavity mould. The elastomer exhibit in Hall 22 is an 80 tonne Boy
80E configured for LSR processing. It will be making cable bush seals on a 124-cavity mould. ❙

Engel Hall 24 Stand A33/B32
Variotherm (heat-cool) mould temperature control features in two of the high technology moulding applications demonstrated on the Engel stand, both producing parts with super-high quality surfaces. In partnership with its customer Wegaplast, Engel
will be producing decorative ornamental trees with a piano black finish on an 80 tonne Victory machine using variotherm mould temperature control from HB- Therm of Switzerland integrated into the machine controller. The trees – which are designed by Francesca Acciardi – are produced in a PC-ABS. In the second application, the company combines variotherm technology from Roctool of France with the
