The corrosion resistance of the cooling channel in water-cooled mold has an important impact on application mold. In this paper, influence experimental temperature roughness and U-shaped channels prepared by casting is analyzed detail. results show that increased from 998 to 1048K; hole wall decreased 83.264 76.287. However, with a further increase temperature. Because low will promote formatio...

Designing cooling channels for the thermoplastic injection process is a very important step in mold design. A conformal cooling channel can significantly improve the efficiency and the quality of production in plastic injection molding. This paper introduces an approach to generate spiral channels for conformal cooling. The cooling channels designed by our algorithms has very simple connectivit...

We newly designed super-elastic biodegradable scaffolds with longitudinally oriented microchannels for repair and regeneration of peripheral nerve defects. Four-armed poly(ε-caprolactone-co-D,L-lactide)s (P(CL-co-DLLA)s) were synthesized by ring-opening copolymerization of CL and DLLA from terminal hydroxyl groups of pentaerythritol, and acryloyl chloride was then reacted with the ends of the c...

Abstract Injection molding is a cyclic process comprising of cooling phase as the largest part this cycle. Providing efficient in lesser cycle times significant importance industry. Conformal proven technique for reduction injection molding. In study, we have replaced conventional circuit with an optimized conformal tool (mold). The required heat transfer rate, coolant flow rate and diameter ch...

We developed an improved Satou mold that can intentionally generate macrosegregation via bridging of the solidification structure and shrinkage flow. Herein, be achieved in a relatively small with inner dimension 30 mmT × 50 mmW 190 mmH. Casting experiments were conducted on Al–10mass%Cu alloy using this mold. The obtained samples analyzed detail by evaluating 3D morphology X-ray CT imaging, an...

Methods for fabricating poly(methyl methacrylate) microchips using a novel two-stage embossing technique and solvent welding to form microchannels in microfluidic devices are presented. The hot embossing method involves a two-stage process to create the final microchip design. In its simplest form, a mold made of aluminum is fabricated using CNC machining to create the desired microchannel desi...
