In injection moulding, high-performance plastics offer excellent properties for achieving special requirements for the desired moulded part. For example, this includes the excellent chemical and hydrolysis resistance on which medical and laboratory technology depends. Extreme chemical resistance, high material purity, dimensional stability and mechanical strength are required in electrical engineering and sensor technology as well as in the automotive industry. In addition, the inherent flame retardancy, very low smoke emission in the event of fire and low weight are crucial factors in aviation. For each of these sets of requirements, there are suitable high-performance plastics in the injection moulding process. However, their processing, from tool design, peripheral equipment and material pre-treatment to the process capability of the injection moulding process, is much more demanding than the processing of conventional engineering thermoplastics.
