In the design of plastic injection moulds, the presence of undercut features would affect mould cost and structure. In this paper, the definition, classification of undercut features and the related notions to identify them are presented. Ba...

Abstract：Rapid heating cycle molding (RHCM) is a novel plastic injection molding process. It can be used effectively to prevent many defects of products produced in conventional injection molding process. In this paper, the panel of large-...

In this study, a novel desiccant based air-conditioning system was considered. This system consisted of a desiccant wheel, heat exchangers, fans, evaporative cooler, electric heater unit to simulate solar energy,and refrigeration unit. A mod...

Can I mold that part with this material in this machine? Its perhaps the oldest question in injection molding, and now theres a way to answer it with more practically relevant data than ever before. Mold designers, part designers and process...

Engine parts in the engine block is a more complex structure of spare parts box, its high precision, processing, complex process, and the processing quality will affect the overall performance engine, so it has become the engine manufacturer...

1. Introduction Injection molding is the most popular method for producing plastic products because of its high productivity and the manufacturability for making various complex shapes. The injection molding process includes six stages: mold...

Impact-induced rock fragmentation is relevant for many fields of science and technology. Impact mills have been applied in mineral, coal, cement and chemical industries for a long time. The literature shows that substantial effort has been e...

Abstract This paper describes mechanism and control of leg-wheel hybrid mobile robot. Legged locomotion has high adaptability for rough terrain, and wheeled locomotion posses speed and eficiency. A new locomotion mechanism that combines legs...
