hot-melt extrusion is one of the most widely applied processing technologies in the plastic, rubber and food industry. today this technology has found its place in the array of pharmaceutical manufacturing operations. melt extrusion process are currently applied in the pharmaceutical field for the manufacture of a variety of dosage forms and formulations such as granules, pellets, tablets, supp...

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...

The characterization of the dielectric properties wood–polymer composites (WPCs) is essential to understand their interaction with electromagnetic fields and evaluate potential use for new applications. Thus, spectroscopy monitored evolution WPCs over a wide frequency range 1 MHz GHz. were prepared using mixtures different proportions (40%, 50%, 60%) wood bark fibers from various species, high-...

This present paper investigates the influenceof clay (Cloisite 10A) and multiwalled carbon nanotubes (MWCNT) loading for tensile, flexural, thermal stability water absorption properties of recycled thermoplastic blend made from high-density polyethylene (rHDPE)and terephthalate (rPET). The nanocomposites were prepared via extrusion blending technique by using extruder compressed hot cold press ...

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...

Single-use plastic applications have resulted in a staggering amount of waste. The total waste was estimated at 80 million tons 2015, showing an increasing trend. A significant proportion the is polypropylene (PP). PP offers good mechanical and chemical properties can be manufactured molded cost- energy-efficient manner. This forcing society to develop sustainable recycling strategies. For this...

In order to investigate the effect of relative motion nano CaCO3 reinforced bamboo pulp fiber (BPF)/HDPE composite components on mechanical performance, a comparative study was performed. BPF treated by blending (BM) and impregnation modification (IM) technology. The composites were produced using hot press (HPMP), extrusion (EMP) injection molding process (IMP). physical morphology similar at ...
