Thermoplastic compression resin transfer moulding coupled with injection is an appealing process for the production of thermoplastic composites. However, its implementation at industrial scale remains challenging as variotherm could prevent solid skin formation in parting line, making cavity sealing difficult. In this study, a tool and related methods parameters are presented. The validity conc...

Carbon fiber composites have become popular in aerospace applications because of their lightweight yet strong material properties. The injection molding process can be used to produce discontinuous fiber composites using less time and resources than traditional methods, thereby broadening carbon fiber composites’ applications in different industries. Utilization of longer fibers offers more loa...

We carry out a nondestructive study of injection-mold weld lines in an acrylonitrile butadiene styrene (ABS) thermoplastic electrical receptacle plate. Terahertz techniques show morphological features at the and reveal terahertz birefringence properties localized around welds, indicating frozen-in molecular orientation stress proximate to welds. Surface acoustic microscopy corroborates welds sh...

An injection molding process was characterized with respect to certain physical characteristics of an injection molded part. The produced part, the “Triconnector”, is a planar Lego-like piece, which was shot from ABS thermoplastic on a Morgan-Press G-100T Injection Molding Machine. Using statistical design of experiments, we identified the most significant parameters affecting part quality. The...

A polymer blend is a mixture of two or more polymers that have been blended together to create a new material with different physical properties. Generally, there are five main types of polymer blend: thermoplastic–thermoplastic blends; thermoplastic–rubber blends; thermoplastic–thermosetting blends; rubber– thermosetting blends; and polymer–filler blends, all of which have been extensively stu...

We demonstrate that fabrication of well-defined nanofluidic systems can be greatly simplified by injection molding of thermoplastic polymers. Chips featuring nanochannel arrays, microchannels and integrated interconnects are produced in a single processing step by injection molding. The resulting open channel structures are subsequently sealed by facile plasma-enhanced thermal bonding of a poly...

Abstract For investigations on a two‐stage multicomponent injection molding process adhesion‐modified polyamide 6 and EPDM with sulfur‐curing system are used. The influence of different temperatures is investigated the basis DoE test plan 15 factor level combinations. Within scope additional, more in‐depth investigations, special focus was given to preheating temperature thermoplastic insert. I...

This study aimed to evaluate the tensile and transverse bond strength of chairside reline resins (Tokuyama Rebase II, Mild Rebaron LC) to a thermoplastic acrylic resin (Acrytone) used for non metal clasp denture. The results were compared with those of a conventional heat polymerized acrylic resin (Paladent 20) and a thermoplastic polyamide resin (Biotone). The failure sites were examined by sc...
