Heat Control simulation for variothermal injection moulding moulds using infrared radiation

چکیده
Abstract Mould temperature control has a significant influence on component quality and costs in the plastic injection moulding process. In case of standard applications isothermal control, which mould is maintained at one level, sufficient. For special (e.g. optics; long, thin components; microstructures) variothermal using cyclically changing temperatures beneficial. Therefore, use infrared radiators offers advantages terms achievable investment but low heating rates efficiency. This paper therefore investigates possibility increasing efficiency energy input by radiation into metals particular aluminium. this purpose, simulation model developed. The numeric models used are validated means experiments. A short-wave radiator investigated, consisting tungsten filament quartz glass tube. emitter power varied from 1200 to 400 W. An aluminium sample with thickness 10 mm square base an edge length 60 investigated. measured non-irradiated side centre surface distance 20 it while being irradiated. numerical model, ray tracing carried out first step, result as Neumann boundary condition for thermal second step. created can serve basis design more complex geometries.

Simulation Tools for Injection Moulding
In this paper the concern is certain simulation tools for the lling phase of injection moulding of plastics. A mathematical model, called the distance model, of the injection moulding process has been developed by Professor Gunnar Aronsson at the University of Linkk oping. From this model one can nd the lling pattern (i.e. ow fronts) of the molten polymer as it enters the mould, by solving a sh...
متن کاملBest practice for benchmarking injection moulding simulation
Injection moulding simulation benchmarking is the comparison of predicted and actual process and quality parameters. Best practice requires that the inputs and outputs from an injection moulding simulation agree to the actual conditions of a real life moulding machine, as closely as possible. The accuracy of injection moulding simulation is influenced by many factors such as: the modelling of t...
متن کاملModelling the Heat during the Injection Stretch Blowing Moulding: Infrared Heating and Blowing Modelling
Effects of temperature: initial heating conditions or self heating during the process, are very important during the injection stretch blow moulding (ISBM) process of PET bottles. The mechanical characteristics of the final products, which are mainly controlled by the final thickness and the orientation of the molecular chains, depend strongly on the process temperature. Modelling the heat tran...
