Influence of the cooling temperature on the mass variation and mechanical resistance of injected ABS

ABSTRACT

Injected ABS parts submitted to different cooling temperatures can present variations on their mass and different levels of mechanical resistance. The purpose of this work is to study the influence of the cooling temperature on the mass variation and mechanical resistance of injected ABS parts. Thereby, initially, specimen with gear shape have been produced under different cooling conditions. Then, the mass variation of the specimen has been analysed with the help of an analytical balance. To verify the mechanical resistance of the studied material, was designed and constructed a mechanical device, which made possible the application of an active loading on two specimens. By obtained results, it was possible observe that with the decrease of the cooling temperature, there was an increase on the mass and mechanical resistance of the injected ABS parts.
