HPDC molds are one of main technologies for mass production. Due to the high velocity of the liquid metal, aluminum die-casting
Myeong Jin Koa, Sung-Ho Leea, Soon Sub Parka* ABSTRACT In this study, a 2.2 kW super-premium (IE4) class 4-pole three-phase induction motor was designed and developed. We compared this prototype motor with the industrial induction motors sold by leading international companies. We designed and fabricated a stator, an Al rotor, housing, bearing front and rear

Daniel Liang, Xu Yang, Jiabin Yu, Victor Zhou Abstract This paper introduces the recent technological progress in China on the manufacture of die cast Copper Motor Rotors (CMR) for induction motors. This manufacturing process provides a simple and practical means for large-scale economical production of high-efficiency induction motors. Rotor die casting obstacles/solutions are presented along
Porosity Control in Copper Rotor Die CastingsE. F. Brush, Jr., S. P. Midson, W. G. Walkington, D. T. Peters and J. G. Cowie Abstract This paper reports on the results of an investigation to minimize and control the distributionof porosity in edge-gated copper rotor die castings. A Flow 3-D computer modelingexercise was used to simulate
1. Overview: 2. Research Background: In metalcasting, cores are essential components utilized to create internal geometries and voids within cast products. The selection and performance of cores are significantly influenced by the casting technique employed, ranging from gravity casting to high pressure die casting. As component designs become increasingly complex and environmental regulations more stringent,
The porosity of die cast parts is one of the primary concerns of buyers and designers. In die casting, porosity refers to the air pockets, small voids, or pores found within a metal part. Too much porosity in a part can be dangerous as it can compromise the structural integrity of the component. Porosity can
Depending on the project, aluminium casting is carried out through a “hot” or “low” process. Diecasting is one of the most economical and fast molding processes. The advantage of this production process is that hundreds of thousands of castings can be produced relatively quickly using a single mold. All parts produced are of uniform quality
Reference : https://diecasting.com/blog/how-to-avoid-die-casting-defects/ The production of die-castings includes a number of steps, any of which can result in a defective casting if not properly executed. Since repairing bad castings can be expensive, it’s important to avoid defect occurrences if possible. We’ll look at some common to areas of die casting defects — including wall thickness
