Many so-called “low carbon footprint technologies” are already available and could be utilized immediately in plastics processing. But what carbon reduction measures are not only environmentally effective? Using practical examples, gwk shows how the use of efficient temperature-control technology rapidly pays off economically, too.

Advantages through Sustainable Temperature-Control Technology

New polymer composites for the production of multi-layer small tubes are being developed to give products specific functions. With suitable co-extrusion dies and a thermal barrier option, even complex layer composites with melt temperature differences of more than 50 °C can be processed reliably and in high quality.

Co-Extrusion with Thermal Control

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.

Where Night Becomes Day

Comprehensive standard equipment, lifetime warranty on key components – HB-Therm presented at Fakuma 2021 the new Series 6 generation of temperature control units. With the Thermo-6 temperature control units, the Swiss company has also further developed equipment technology, improved energy efficiency and expanded digital services.

This is what the Thermo-6 series looks like. The smallest of the three was introduced to the market in October 2021. The larger and more powerful variants are expected to follow in 2022 and 2023.

Avoiding Shutdowns

In the injection molding of engineering plastics, mold temperature control consumes more than one third of the total energy input. A novel technology offers the opportunity to reduce this continuous major cost factor – and eliminate hotspots.

Pipette tips feature a challenging wall thickness/length ratio, an inner geometry that is key for analysis results, and a tip opening just a few tenths of a millimeter wide. They have been in extremely high demand during the coronavirus pandemic, which is why the mold construction and hot runner specialist Männer has developed a mold with an innovative cluster concept.

At the Männer test center in Bahlingen, Germany: an injection mold for manufacturing pipette tips, shown here in operation. Automation of the system is currently being set up
