High precision, high quality, extreme cleanliness: these are the prerequisites for perfect optical parts. For this purpose, the ARBURG range includes high-end applications. These can be used for the injection moulding of thick-walled optical parts or for the reliable replication of micro structures, for example.
Ready-to-use design product in one shot
‘Ready to wear’: The example of the UVEX sunglasses shows its potential when combined with a product design in line with the plastics used and automated production. The one-piece sunglasses in filter category 2 can be produced efficiently and cost-effectively in one step without assembly.
The production cell around an electric injection moulding machine ALLROUNDER 570 A ensures an extremely reliable process: From component-specific laser marking to checking the light transmission and UV impermeability right through to sprue separation. The sunglasses are packaged in a functional bag, for example, by a man-robot cooperation.
Compression moulded optical parts
ARBURG participates in the OptiLight research project for the energy-efficient production of innovative hybrid lenses for LED streetlights. With the injection compression moulding process, precision free-form surfaces are produced which deflect the light in a targeted manner, according to a rectangular illumination profile.
The energy-efficient LED lenses are produced using an equally energy-efficient electric ALLROUNDER ALLDRIVE injection moulding machine. The project is sponsored by the German Ministry of Education and Research (BMBF) and supervised by Projektträger Karlsruhe (PTKA). The objective is an efficient production chain for the high-volume production of microstructured, thick-walled polymer hybrid lenses.
to the moulded part
The electric injection moulding machines of the ALLDRIVE series are predestined for high-precision optical applications such as the automated production of optical waveguides made from PC. Maximum part quality and precision are required here owing to the surface microstructures, which measure 5 nm.
Reliable replication of the microstructures is achieved through a high mould temperature of 120°C. The horizontally-operating MULTILIFT H robotic system gently removes the optical waveguides and transfers them to an optical testing station. All the peripherals are integrated in the SELOGICA control system so that the entire production process can be monitored seamlessly and centrally.
