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.

iQ motion control from Engel now allows reliable early start combined with fully automatically optimized motion planning. The assistance system has been part of the standard kit of all new Engel viper-type linear robots since October 2021.

If the robot travels into the mold area already during the mold opening movement, this can shorten the cycle time. The effect is particularly large in the case of parts with long cores, such as boxes

Sixth Unit Generation Celebrated Premiere at Fakuma 2021

Comprehensive standard equipment, lifetime warranty on key components – HB-Therm presented at Fakuma 2021 the new Series 6 generation of temperature control units.

According to HB-Therm CEO Reto Zürcher, insights such as the practicality of the units in daily use and a brilliant touchscreen for convenient operation with modern designs and colors were not only derived from a comprehensive market analysis, but also from collaboration with key customers who brought the needs of injection molders into the evolution phase. “Our thoughts were influenced not only functionally but also visually. In addition, of course, we verified our findings repeatedly in practice for their suitability for everyday use. For us, highest quality has a clear foundation: And that means testing, testing and testing again!”

In addition to the lifetime warranty on the heater uniquely offered by HB-Therm for the predecessor units, customers of Thermo-6 units also benefit from a lifetime warranty on the ultrasonic flow meter. All components were designed to be extremely robust and durable. Martin Braun, CTO of HB-Therm says: “This step has been made possible by the expertise gained from the development of the high temperature water units Thermo-5 up to 230 °C!”

Based on the proven technology of the Thermo-5, the new units have been consistently enhanced, standardized and modelled with useful aids such as a visual alarm via LEDs in the front base area. The very low maintenance requirements also make the Thermo-6 attractive in terms of upkeep.

HB-Therm considers the standard integration of a speed-controlled pump in the new unit series to be part of its environmental commitment. With the Energy-Control Assistant, an optimal operating point can always be achieved, even without any prior knowledge on the part of the user.

The result is up to 85% less power consumption. In addition, a new sealless Direct-Drive pump is used for the units up to 100 °C, which was developed exclusively for HB-Therm together with a renowned pump supplier. This canned motor pump sets new standards in efficiency and compactness.

“A pump that does not always run at full load not only saves energy, but also has a longer service life. In addition, speed-controlled pumps can be used universally for large and small molds, thus reducing the variety of types of temperature control units. One unit for all tasks”, explains Martin Braun, Head of Development at HB-Therm.

A difference to the Thermo-5 that immediately catches the eye is the touch display of the Thermo-6, which is four times larger at seven inches. The operation is clearly oriented towards modern smartphones, allowing users to master the Thermo-6 in no more than ten minutes. Individual settings and favorite selection modes, plain text instructions with QR codes for further information, wizards for setting up the units, swiping and scrolling also make it easy to find the desired operating pages quickly on the display of the new Series 6 units. Graphic and text pages make intuitive navigation easy. The Expert system helps, warns, reports and optimizes unit operation. In this way, even complex setting procedures are very easy to handle.

The process data is recorded locally. Unit history and unit-specific documents such as certificates, calibration data, operating and assembly instructions can be displayed quickly and clearly on the new, large screen. Clearly arranged, setters and operators can always find exactly the parameter page they need quickly and with just a few clicks.

HB-Therm defines digitalization as contemporary, mobile, independent, useful and supportive. The future-oriented hardware and software architecture of the Series 6 allows comprehensive access to the digital world of HB-Therm. The digital solutions in addition to the standard OPC-UA Ethernet interface on each Thermo-6 are called Gate-6 and e-cockpit.

Gate-6 is an interface server that establishes the connection (gateway) to the Android app e-cockpit and the digital services of the HB-Therm world as well as between several Thermo-6 and/or Thermo-5 units and other external systems such as injection molding machines.

Gate-6 accesses the functions of the HB-Therm cloud via the LAN connection of the units. This allows users to send analysis data, track the “digital twin” in the company’s Ticket system, generate unit statistics and overviews as a part of customer service, the keeping of a maintenance overview as well as the preventive maintenance of the connected units.

The e-cockpit app is a mobile application for smartphones and tablets and accesses a Gate-6 locally as well as the temperature control units connected to it. It secures access to the company’s Ticket portal with several functions. Via this access, the user can, among other things, process error messages and warranty cases as well as obtain technical support. Ticket is therefore a central application that brings together data from several Gate-6 interface servers and temperature control units and makes it available online. This requires a central data server and Internet access. Recorded data and settings are only sent to HB-Therm Support if they have been released by the customer and in accordance with the highest security standards.

In addition to the standard features already mentioned, the Cleanroom package, OPC UA interface and pump status monitoring are now also standard. A separate screen protector is also no longer necessary, as the new screen has a very robust design. Also new, but available at a later date, will be filter screen monitoring. This makes it easy to clean clogged filters whenever the need for it actually arises.
