Analysis of a Feasible Gate Location in Injection Mold for Plastic Cloth Peg: New Product Development

Abstract

Abstract: Product design is the most important and invaluable factor to determine success of a product. Its role changes consistently throughout the life cycle of a product. It is well known that the ultimate design of a product is dependent on various influencing factors right from material and process selection to the end use as well as re-use of the product. These factors put challenges in front of designers and manufacturers of consumer goods. Judicious utilization of material and other resources along with optimized profit are the constraints to control. It is achievable only if the design concepts and the manufacturing experience is used in the correct combination. This article aims at illustrating a new product development process for a plastic part and analyzing it on the parameters of few process constraints related to its manufacturing process viz. gate location. The product considered for the study is clothe peg, which is individually made up of plastic, unlike existing similar products made in combination of plastic and metal parts. This part is analyzed by considering its manufacturing by injection molding process. A model mold was also prepared for validation of the research findings.
