Fast Prediction of Injection Pressure and Minimal Front Temperature for Injection Moulding

International Polymer Processing, 2011
Abstract Fast prediction of injection pressure and minimal front temperature can usually be used to optimize the process parameters for injection moulding. In this paper, a fast strip analysis (FSA) model was presented on the basis of a geometric approximation method, which simplifies an original part to a rectangular edge-gated strip ...

Room-Temperature Spin Injection from Fe into GaAs

Physical Review Letters, 2001
Injection of spin polarized electrons from a metal into a semiconductor is demonstrated for a GaAs/(In,Ga)As light emitting diode covered with Fe. The circular polarization degree of the observed electroluminescence reveals a spin injection efficiency of 2%. The underlying injection mechanism is explained in terms of a tunneling process.

Self-optimizing MPC of melt temperature in injection moulding

ISA Transactions, 2002
The parameters in plastic injection moulding are highly nonlinear and interacting. Good control of plastic melt temperature for injection moulding is very important in reducing operator setup time, assuring consistent product quality, and preventing thermal degradation of the melt.
