A facile method enabling the integration of elastomeric valves into rigid thermoplastic microfluidic chips is described. The valves employ discrete plugs of elastomeric polydimethylsiloxane (PDMS) integrated into the thermoplastic substrate and actuated using a threaded stainless steel needle. The fabrication process takes advantage of poly(ethylene glycol) (PEG) as a sacrificial molding materi...
This research was conducted to investigate the bond strength between artificial teeth and a thermoplastic denture base resin for injection molding with different surface preparations use in flexible removable partial dentures. Composite acrylic were bonded three types of resins (polyamide, polyester, polycarbonate) conventional heat-polymerized polymethyl methacrylate (PMMA) (control). The ridg...
Injection molding is widely used to produce plastic components with large lot size. However, quality failures occur during cycles. These can be minimized through real-time process monitoring. This article reports on a cloud-based digital twin (DT) that supported by A-based control of parameters and help companies detect product in real time. Process their interrelationship failure were studied ...
We present an all-thermoplastic integrated sample-to-answer centrifugal microfluidic Lab-on-Disc system (LoD) for nucleic acid analysis. The proposed CD system and engineered platform were employed for analysis of Bacillus atrophaeus subsp. globigii spores. The complete assay comprised cellular lysis, polymerase chain reaction (PCR) amplification, amplicon digestion, and microarray hybridizatio...
The goal of this study was to evaluate the thermoplasticity of conventional and thermoplastic gutta-percha and Resilon, a polyester polymer-based material. Specimens with standardised dimensions were made from the following materials: conventional and thermoplastic gutta-percha (Dentsply), conventional and thermoplastic gutta-percha (Endopoints) and Resilon. After 24 h, the specimens were place...
Thermoplastic polyamide elastomer (PAE) [also PEBA: polyether block amide] is one of the most recently developed of the thermoplastic elastomers: a multiblock polymer with polyamide hard segments, it uses longchain polyether diol or polyester diol of low Tg for its soft segments. Polyamide 6 or polyamide 12 (PA12) is the main polyamide component used, while the soft segments are mostly provided...
Computer simulation of injection moulding process is a powerful tool for optimisation moulded part geometry, mould design and processing parameters. One the most frequent faults parts their warpage, which result uneven cooling conditions in cavity as well after ejection from down to environmental temperature. With computer it possible predict potential areas warpage apply remedies compensate/mi...
The work proposed a novel thermoplastic forming approach-the ultrasonic beating forming (UBF) method for bulk metallic glasses (BMGs) in present work. The rapid forming approach can finish the thermoplastic forming of BMGs in less than one second, avoiding the time-dependent crystallization and oxidation to the most extent. Besides, the UBF is also proved to be competent in the fabrication of s...
The main objective of the research presented here was to relate anatomical features of wood species that affect the interactions between polymeric phases and performance of wood plastic composites (WPC). These interactions were related to the probable interlocking volume and surface area for stress transfer in a WPC. Composites were produced from different wood species and analyzed using SEM (s...
The paper presents preliminary numerical and experimental studies of active textile-reinforced thermoplastic composites with embedded sensor-actuator arrays. The goal of the investigations was the assessment of directional sound wave generation capability using embedded sensor-actuator arrays and developed a wave excitation procedure for ultrasound measurement tasks. The feasibility of the prop...
