A new 16 mm twin-screw extruder permits optimisation of processing parameters even when only small quantities of material are available, production of test specimens or performance of quality control inspections. The system can be matched to the task at hand with only a few modifications.

It is increasingly common to place identification labels on parts during assembly. A multi-layer film with a laser-activated inner layer offers many benefits in this regard.

Advanced processes and materials now make it possbile to produce plastic parts in series quickly and economically via laser sintering. This tooling-free manufacturing method minimises the risks associated with investment of capital and presents new design freedom.

Wilden AG employs cube moulding for production of the “HandiHaler“ inhaler. The moulds are especially well-suited for high-speed, economical production of large quantities.

The technique of computer tomography that has become commonplace in the field of medicine can also be employed for analysis of plastic parts. In this way, the first parts out of a mould can be examined in a nondestructive manner.

With the new XX Series of twin-screw extruders, Leistritz intends to increase productivity in compounding. Higher throughputs, shorter changeover times and greater flexiblity of the compounding system will form the basis for this.

Flexring dies for extrusion blow moulding make it possible to change the die gap at any location on the circumference of the die. As a result, production of more complex parts now becomes feasible. In addition, application of dynamic wall thickness control can be extended to small die geometries.

The so-called high-intensity plasticizer, which is characterised by its extremely short length, represents an inexpensive concept for processing thermoplastic resins. The feed, compression and metering (discharge) zones are arranged coaxially; the resin is plasticized solely by means of friction. Initial investigations show good results when processing a variety of semi-crystalline and amorphous thermoplastics.

A new processing technique combines gas-assisted injection moulding with blow moulding. The technique permits moulding of complex plastic parts that integrate a void or channel with a large cross section and thin walls.

In the area of color measurement, Internet-based color management systems are being employed increasingly in place of individual solutions. This new approach offers decisive benefits for large companies with worldwide operations as well as for small and medium-sized companies.
