The main objective of this paper is to predict the warpage of a circular injection molded part based on different processing parameters. The selected part is used as spacers in automotive, transmission, and industrial power generation industries. The second goal is facilitating the setup of injection molding machine without (any) need for trial and error and reducing the setup time. To meet the...

Abstract. This study aimed to explore the capability of different additive manufacturing (AM) or 3D printing technologies rapidly manufacture mold inserts for injection molding as well evaluate performance printed and quality molded parts. Fused filament fabrication (FFF), stereolithography (SLA), multi-jet fusion (MJF) were used produce inserts, whereas a cosmetic compact base was selected cas...

Rapid heat cycle molding (RHCM) is a special molding process capable of producing molded plastic parts with high surface quality and improved weldline strength and appearance. This study investigated the influence of the weldline on the tensile strength of RHCM and conventional injection molded (CIM) components. The test specimens with and without a weldline were cut from RHCM and CIM parts for...

The encapsulation of mammalian cells within the bulk material of microfluidic channels may be beneficial for applications ranging from tissue engineering to cell-based diagnostic assays. In this work, we present a technique for fabricating microfluidic channels from cell-laden agarose hydrogels. Using standard soft lithographic techniques, molten agarose was molded against a SU-8 patterned sili...

Compression molding of glass optics is gradually becoming a viable fabrication technique for high precision optical lenses. However, refractive index variation was observed in compression molded glass lenses, which would contribute to image quality degradation. In this research, annealing experiments were applied to control the refractive index variation in molded glass lenses. The refractive i...

Acquiring holistic and accurate 3D measurements for industrial parts is highly demanded in the fields of quality control, process optimization and product development. The increasing complexity in the design and miniaturization make the task of holistic 3D data acquisition difficult. For the last few years, industrial computed tomography (CT) has emerged as a promising coordinate measuring tech...
