In the idea of improving the performances of both full and removable partial dentures, new materials and technologies are coming on the market, promising a better quality. Thermoplastic materials are used more and more widely in the technology of complete or removable partial dentures due to their superior qualities. Thermoplastic resins are suitable for manufacturing a wide range of removable ...

Background: The accuracy and the reproducibility of radiotherapy can be provided by using immobilization devices such as thermoplastic masks. In head and neck cancer radiotherapy, the patients are mostly immobilized by using thermoplastic masks. In this study, the effect of the thermoplastic mask to the surface and buildup region doses was investigated by using Markus parallel plate ion chamber...

Abstract In this study, we present a novel approach for the production of continuous fiber-reinforced thermoplastic composites by combining injection molding and additive manufacturing. After exploring design requirements, manufactured inserts via 3D printing, then used them as reinforcement injection-molded samples. Improper fiber placement can cause warpage fibers prevent shrinking; however, ...

applications of thermoplastic composites have developed extensively. the thermoplastic composites in comparison with the thermoset composites have many advantages. thermoplastic composites can be melted and remolded many times. the duration of manufacturing process of these composites is short, producing very tough material, and the welding ability and multiple recyclings are their further adva...

Injection molding is a manufacturing process for producing parts from both thermoplastic and thermosetting plastic materials. When the material is in contact with the mold wall surface, one has three choices: i no slip which implies that thematerial sticks to the surface ii partial slip, and iii complete slip 1–5 . Navier 6 in 1827 first proposed a partial slip condition for rough surfaces, rel...

This paper compares the performance of two alternative HVAC fan designs: a five-blade injection molded thermoplastic design, against the more traditional three-blade stamped metal version. The study was conducted using computational fluid dynamics techniques, along with finite element structural analysis, in which we attempted to optimize the air movement characteristics of the fan, as well as ...

A soft lithographic method is described for casting functional thermoplastic devices with microscale features without the need for specialized tools or equipment. In the thermoplastic soft lithography process, termed solvent casting, low temperature supersaturated solutions of thermoplastic are poured over solvent permeable PDMS molds which allow omnidirectional solvent removal as they template...

Overmolding process is one of the growing advanced technologies for fabricating lightweight composite structures used in aerospace and automotive industries. This technology enables integrating multiple types reinforcements from macro- to nano-scale thermoplastic thermoset matrices assembling dissimilar polymeric materials. Besides, this well suited a digitalization manufacturing complex geomet...
