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.

Miniaturization is a Megatrend

Temperature Control with Water up to 230 °C as a Substitute for Oil

Processing of High-Performance Plastics without Purity Problems

In order to minimize the risk of contamination in the production of medical products, Scholz HTIK (High Tech in Kunststoff) decided to change its temperature control processes from oil to water as a heat transfer medium. As practical experience has shown, the P230S pressurized-water temperature control unit developed by Regloplas meets all the requirements for utilizing the better physical temperature control properties of water in the temperature range up to 230 °C.

In order to minimize the risk of contamination in the production of medical products, Scholz HTIK (High Tech in Kunststoff) decided to change its temperature control processes from oil to water as a heat transfer medium.

Semi-crystalline high-performance plastics, such as polyetheretherketone (PEEK) and (polyphenylene sulfide) PPS, which are high temperature-resistant thermoplastics, are nowadays used in high-precision applications in the fields of industrial components, medical technology, diagnostics and the automotive industry. Thanks to the high strength and durability of the plastic, these plastics are increasingly used as metal substitutes in the manufacture of medical implants.

In injection molding the temperature control process for plastics with melting points above 300 °C and mold temperatures greater than 200 °C was, until now, determined by temperature control units with oil as the heat transfer medium. With the development of the high-precision P230S temperature control unit with a patented, integrated pressurizer (manufacturer: Regloplas AG, St. Gallen, Switzerland), it is now possible to carry out the temperature control of injection molding machines, on which high-quality plastics are injected, with water as the heat transfer medium.

Compared with oil, water has double the specific heat capacity (describes the property of how much heat energy a heat transfer medium can transport) (Table 1). Another advantage is the low viscosity over the entire range of application compared with oil. With a system pressure of approx. 30 bar, water has the feature of becoming less viscous.

As a heat transfer medium, water also offers many advantages in its application: alongside at least double the heat transfer coefficient, it also offers a reduction of oil-dependent contamination. There is no evaporation of oil, which means higher purity in the machine as well as a significantly minimized risk of injury to the machine personnel in the event of leaking heat transfer medium.

Lower Flow Temperature,  Shorter Heat-up Time

Weighing these arguments, Horst Scholz GmbH & Co. KG, Kronach, Germany, decided to change its temperature control processes in the manufacture of medical products from oil to water. The mold sizes in production at owner-managed family business, which has maintained a business relationship with temperature control unit manufacturer Regloplas for more than 20 years, move in a range of 50 to 250 kg. An oil temperature of 236 °C must be configured in the temperature control unit in the case of a mold temperature of 220 °C with an oil temperature control unit, whereas a flow temperature of just 224 °C is needed in the device with water as the heat medium. The temperature control process is thereby shortened, which is especially evident in the heat-up time that is almost halved.

High-performance plastics such as PEEK are attractive alternatives to metal. Scholz uses the material for a wide range of applications. In the field of medical technology, Scholz produces rotors made of PEEK material for use in heart pumps. Due to the purity in the production process, the P230S temperature control unit is used in this application, which works with the temperature control medium water in the temperature range up to 230 °C.

Rotor and Bearing Cage for a Cardiac Support System

Miniaturized components, which are directly used in the bloodstream, belong to the highest risk class. This includes the various types of ventricular assist devices (VAD). This is a mechanical pump that supports the heart when it is too weak due to illness. Extremely high demands are placed on the durability of the rotor (Fig. 1), whose blade profile with a wall thickness of 200 µm must be able to withstand rotations of 30,000 to 50,000 rpm in use [2]. PEEK has various advantages in this case, such as its very low weight, high chemical resistance, simple sterilization, biocompatibility and high specific strength.

The rotor made of PEEK is used in a heart pump (Fig. 2) manufactured by Abiomed. With an outside diameter of just 4 mm, this is one of the smallest support systems in the world according to the manufacturer. A ball bearing cage (Fig. 3) is also used in the Abiomed heart pump. This component is also made of PEEK – in a single tool with seven radially aligned sliders. With an outside diameter of 2.3 mm and a molded part weight of 0.8 mg, it is the lightest injection-molded part that Scholz HTIK currently produces. A small component in a high-performance application – the processor also uses the P230S pressurized-water temperature control unit for this manufacturing process.
