Epoxy molding compounds have been developed which can simultaneously underfill and overmold the Flip Chip die in a single transfer molding process. Transfer molding is a well-defined industry process; with suitable mold design, these materials can utilize the currently installed capital base. The ability to apply pressure during the molding process can reduce the void rate under the die as well...

Polyethylene terephthalate (PET) bottles which are thermoplastic materials used very commonly for the storage and transport of carbonated beverages. The most production method PET is Injection Stretch Blow Molding (ISBM) process. There a variety parameters affecting produced bottles’ performances. Amongst these parameters, stretch rod movement, blowing pressure preform surface temperature impor...

E. Ragan, J. Dobránsky, P. Baron, M. Kočiško, J. Svetlík, Technical University in Košice, Slovakia Most plastic parts used in automobile production are manufactured by injection molding. Their quality depends also on taking out molding and on the manipulators for it. Task of this contribution is to theoretically describe a transport of molding at taking out after injection molding in relation o...

Objective. Short-term nasal forms following primary lip repair were compared between presurgical nasal molding and control groups. Aim. To compare nasal symmetry between patients that had nasal molding and lip repair with those that had only lip repair. Design. Retrospective case-control study Patients. Complete unilateral CL+P patients had basilar and frontal photographs at two time points: (1...

in this paper, we consider singular and degenerate parabolic equations$$u_t =(x^alpha u_x)_x +u^m (x_0,t)v^{n} (x_0,t),quadv_t =(x^beta v_x)_x +u^q (x_0,t)v^{p} (x_0,t),$$ in $(0,a)times (0,t)$, subject to nulldirichlet boundary conditions, where $m,n, p,qge 0$, $alpha, betain [0,2)$ and $x_0in (0,a)$. the optimal classification of non-simultaneous and simultaneous blow-up solutions is determin...

Simulation of the stretch blow molding (SBM) process necessitates to develop a model able reproduce material behavior at high strain rate, large deformation with temperature gradient. On other hand, both need understand polyethylene terephthalate (PET) characteristics and final bottle performance requirements continue get higher. That regular update identification model. Bottle producers are in...

Active packaging has played a significant role in consumers’ health and green environment over the years. Synthetic polymers, such as poly(ethylene terephthalate) (PET), polyethylene (PE), polypropylene (PP), polystyrene, poly(vinyl chloride) (PVC), polycarbonate (PC), poly(lactic acid) (PLA), etc., naturally derived ones, cellulose, starch, chitosan, are extensively used materials due to their...
