Quality improvement and productivity enhancement of a single screw HDPE pipe extrusion machine: A case study

Abstract

In the HDPE pipe manufacturing industry, power consumption is the main factor that increases the product's manufacturing cost. This paper aims to reduce the power consumption and increase the surface finish of the HDPE pipe. This work highlights the increase in production efficiency of HDPE pipe factory. First, consider power consumption reduction by using gearbox in the place of no. of pulleys and belt drive and also by this gearbox, the motor size has also reduced which reduces the power consumption and increases the plant's efficiency. Second, to improve the surface quality of the pipe, a cooler is used as a cooling tower to reduce the temperature of the water used to cool down the temperature of the pipe. Results after Modifications around 50% cost of power consumption is reduced per machine and overall power consumption of the plant is reduced by 45.45%.
