“…For a complex part, the injection speed and mold temperature became statistically significant. Bellantone et al [8] investigated the process parameters on the overall quality of a miniaturized dog-bone-shaped specimen by experimentation, and determined that melt temperature is the most important parameter that affects the variability of the process. Tosello et al [9] analyzed weld lines on micro-injection molded parts using atomic force microscopy (AFM), and discussed the influence of typical injection molding parameters on the weld lines' dimensions.…”

An ultrasound-assisted micro-injection molding method is proposed to improve the rheological behavior of the polymer melt radically, and a micro-injection molding system based on a longitudinal ultrasonic vibration core is developed and employed in the micro-injection molding process of Fresnel lenses. The verification experiments show that the filling mold area of the polymer melt is increased by 6.08% to 19.12%, and the symmetric deviation of the Fresnel lens is improved 15.62% on average. This method improved the filling performance and replication quality of the polymer melt in the injection molding process effectively.

“…Therefore, microinjection molding has become the hot topic and has attracted more attention in material processing engineering, especially in the bio-pharmaceutical field. For instance, Bellantone et al [4] investigated microinjection molding parameters on overall quality of a miniaturized dog bone-shaped specimen in order to determine the process constraints. Park et al [5] prepared microneedles with microstructures made from PLA, PGA and PLGA.…”

“…e polymer processing technology, in which one of the trends is to miniaturise both equipment and products, has not been le una ected by this development. Examples of miniaturisation include processing procedures, such as micro-injection moulding and micro-extrusion performed using microinjection moulding machines and micro-extruders [1][2][3][4].…”

Micro-extrusion is the process of obtaining microtubes with either simple or complex cross-sections which are used for the high-precision transport and protection of various of media. rough this process, it is possible to create tubing with interior diameters and wall thicknesses as small as 0.1 mm and 0.05 mm respectively. Micro-extruded tubing such as micro catheters and peripheral intravenous cannulas are employed in micro uidics, paediatrics and micro-analytics. is article presents the results of granulometric tests of micropellets produced by micro-extrusion with cold pelletizing and results of tensile strength tests of microrods of di erent diameters. e trials were performed using a standard twin-screw extruder and low-density polyethylene.Keywords: polymer micro-extrusion, low-density polyethylene, micropellets Streszczenie Mikrowytłaczanie to proces wytwarzania mikrorurek prostych lub złożonych w przekroju poprzecznym, używanych do wysoce precyzyjnego przesyłu oraz ochrony różnych mediów. Dzięki temu procesowi możliwe jest uzyskanie rurek o średnicy wewnętrznej i grubości ścianek tak małych jak 0,1 mm i 0,5 mm. Rurki wytłoczone w ten sposób, np. mikrocewniki i kaniule dożylne, stosowane są w technikach mikroprzepływowych, pediatrii i mikroanalizie. Niniejszy artykuł przedstawia wyniki testów granulometrycznych mikrogranulek wytworzonych poprzez mikrowytłaczanie z granulowaniem na zimno, jak również testów wytrzymałości na rozciąganie mikrożyłek o różnych średnicach. Próby zostały przeprowadzone przy użyciu standardowej wytłaczarki dwuślimakowej i polietylenu małej gęstości.Słowa klucze: mikrowytłaczanie polimerów, polietylen małej gęstości, mikrogranulki 160
