Mold design and technology for the production of plastic spur gears with asymmetric teeth for sugar industry

Abstract

An analysis of the injection molding process of plastic gears, showing its advantages regarding width machining process it is made in this paper. Calculation procedure for designing and molding of spur gears with asymmetric teeth is offer, including necessary tools for obtaining high quality surface finishing of gears made from thermoplastic materials generally used in sugar industry. The procedure includes different molding parameters such as number of cavities, cooling time, injection points, etc. Molded spur gears, tools, machines and molds are showed.
