This year, the world’s leading trade show K has succeeded in presenting practical solutions for greater resource efficiency on a broad front. A first foray through the trade show grounds.

K 2022 gave numerous practical examples showing visitors how recyclates can be reliably processed with digital aids.

It Can Be Done!

Once again, the K 2019 in Düsseldorf, Germany, lived up to its claim to be the leading trade show for plastics technology. At least in the field of injection molding, there were exciting global innovations to see – if you looked closely.

Technical Excellence thanks  to Digital Assistance

Arburg has adopted a clear message for its trade fair appearance at the K 2022 in Düsseldorf: „There is only a Plan A“.

In the arburgGreenworld pavilion of the VDMA Circular Economy Forum, an Allrounder 370 A with recyclate package is manufacturing “Greenline” wall plugs from Fischer.

Sustainability thanks to Digitalization

Mold breathing provides useful information about the processes that occur in the mold and the cavity. Mold-maker Schneider Form and injection molding machine-maker Engel have recognized the potential which this process variable offers and have worked intensively on it for several years, albeit by adopting different approaches. They recently carried out joint tests on bumper molds using a two-platen injection molding machine with a clamping force of 40,000 kN and then swapped experiences.

Bumper molds were the focus of mold-breathing studies aimed at process optimization. The photo shows an example from the bumper portfolio of Schneider Form

Using Breathing Signals for  Process Optimization

Over past months, many in-house workflows and development processes have slowed down and also changed. Nevertheless, time has not stood still, also not in injection molding technology. The debate and development have been shaped by two themes: digitalization and the circular economy. Below are some examples of developments and projects that underpin this trend.

There Is More beyond the Horizon

Engel has developed a new way to process plastic scrap as flakes on an injection molding machine straight after grinding. This innovation eliminates the pelletization step and significantly boosts the economics of plastics recycling. The key to consistently high product quality is to vent the plastic melt.

Test setup at the pilot plant in St. Valentin, Austria: for the two-stage process, Engel has combined a plasticizing screw with an injection screw.

Production systems for large molded parts can be flexibly and economically reconfigured or expanded using hot runner adapter plates.

Flexible Injection Solutions  with Adapter Plates

In the manufacture of semi-finished products such as fibers or films, waste that can be recycled and reused as a raw material is repeatedly produced along the entire production chain. The recycling of PET is a particular challenge to the plant construction because of the hydrolytic polymer degradation.

Two new models of the Eco product family from Ettlinger take into account the need for systems with a higher product throughput.

High Performance Melt Filters for Higher Throughputs

Consider this paradox: sensitive PET is particularly demanding when being processed because it undergoes rapid thermal and mechanical degradation, yet when PET preforms are being produced scant attention is paid to designing the all-important hot runner to suit the individual product. Much more often, a manufacturer will use several cold halves and a hot one and produce articles weighing from 6 to 40 g. Darmstadt University of Applied Sciences, Germany, and mold specialist MHT conducted a research project aimed at determining how the hot runner design affects preform quality.
