Journal of the institution of engineers (India): Series CSummary: plastic industry is widely spread in the world, with plastic injection moulding being the most popular technique due to its high efficiency and cost-effectiveness. In the competitive scenario, when thousands of pieces are produced per day, it is important for the manufacturers to evaluate and improvise the cost per component and productivity rate as even a small change can bring significant improvements in the profits. Various cost factors are considered for cost estimation of plastic injection-moulded component such as material, mould, processing and post-processing costs. Mould cost being very high is a major cost component and differs when using straight drilled conventional cooling channels compared to the one using channels conforming to the shape of the component. For parts having an intricate shape and high precision, it is always recommended to use conformal cooling channels as they reduce the defects and cycle time. The manufacturing cost also depends on component size, number of cavities, cycle time and labour cost. Another important parameter influencing production cost is the cycle time and cooling time. With the use of conformal cooling channels, processing cost can be reduced by reducing cycle time, thereby improving the production rate. In this paper, a comparative economic analysis is performed for a plastic injection-moulded product manufactured using conventional cooling channels with the one manufactured using conformal cooling channels.
