At the 2019 K fair, Arburg and Simcon showcased a filling process proceeding in real-time, as a 3D animation, on the display of a machine control panel, for an example of sunglasses, made of PA12. All that was needed to prepare this, was to load the simulation model, as well as the geometry of the part, directly onto the machine controls. This sounds almost too easy to be true. Right?

Anyone seeking to replace a metal component by a plastic one, to reduce the number of component parts from eight to three and simultaneously cut both the weight and manufacturing costs needs to take great care to ensure that all specifications are met – especially if the component is used in a hot gearbox and is subject to high mechanical stress.

The shifter fork creates a positive lock between the gear wheel and the shaft so that the engine power can be transmitted to the wheels

Replacing Metal in the Gearbox

Internal pressure loads are typical for fiber-reinforced plastic components. To increase the burst strength of components, the fiber orientation can be modified in a targeted way during injection molding by means of a rotating mold core. A newly developed simulation method allows this modified fiber orientation to be taken into account at the design stage.

Automotive supplier Friedrich Deutsch Metallwerk has combined the die casting of a metal insert and its overmoulding with plastic in a single tool.

A new combination of conventional processing methods – high-pressure die-casting and injection molding – could lead to a more efficient process.

A tool logbook on paper is often not to hand just when you need it most. Or it is incomplete, since it is time consuming to keep the information up to date. A cloud-independent, electronic tool log, which is directly integrated into the tool could make all the relevant data available directly.

Marbling is often a real eye-catcher in plastic components. However, the effect is difficult to create and there are some pitfalls when it comes to reproducibility. Novel nozzles for injection molding machines in combination with a special dosing technology allow marbled molded parts to be produced far more easily in a much more robust process.

Marbling leads to attractively designed molded plastic parts, but is not so easy to implement in production

Exciting Design instead of  Exciting Manufacturing

Hybrid production chains have been increasingly in the spotlight in recent years. This also applies to the combination of conventional manufacturing and additive processes in tool construction. With the example of an injection molding tool, it is shown how mold inserts produced by additive manufacturing can greatly shorten cycle times, and thereby significantly reduce unit costs. The important thing is to find a suitable combination of processes from the variety available.

The Potential of Redesign and  Part Consolidation

Starting with the systematic design of manufacturing processes and the precise simulation of part manufacture, through smart tooling technology and sophisticated melt guidance, to efficient mold temperature control, numerous exhibitors have many innovations in the field of tooling technology on offer at K 2019.The current debates concerning marine pollution as well as anthropogenic climate change and its consequences seem to be having an effect at this world-leading trade show for plastics processing in Düsseldorf, Germany. A number of companies are noting the growing customer interest in sustainable, carbon-neutral and resource-efficient modes of production, and offering products and services intended to satisfy this interest.
