The hot embossing of thermoplastic materials, such as polymethylmethacrylate (PMMA) or cycloolefin copolymer (COC), is a promising way to manufacture microfluidic channels and networks [1]. Hot embossing potentially offers lower per-area cost than the micromachining of quartz or silicon and easier scaling-up of production than soft lithography using polydimethylsiloxane [2]. In hot embossing, a...

The cooling control of the melt during casting process is great significance. A comprehensive closed-loop castings by adopting a skeletal sand mold design was proposed. consisting an adaptive shell, functional cavities and support designed created based on finite difference meshes casting. It applied to round wall test Two kinds molds, one with lattice other enforcing ribs for this were printed...
