“…Titow and Turner [19] discussed some of the key aspects of injection moulding of PVC and stated some remedial steps for improving the quality of the moulded parts. Dalal [20] described some of the important characteristics of CPVC and stated the advancements made in processing it in the last few years. Paturi et al [21] used ANN to optimise the sink-mark depth along with the weld-line breadth of an injection-moulded PMMA component.…”

The need for fire-retardant material for electrical wire covers and cases is increasing as the global population continues to expand at an alarming rate. In addition to having good fire and chemical resistance, CPVC (chlorinated polyvinyl chloride) is widely accessible in a assortment of forms and sizes, comprising rods, sheets, and tubes. Plastic injection moulding (PIM) provides a method that allows for the production of CPVC items at a rapid pace and at a low cost. When these mouldings are lightweight, they may reduce the amount of non-biodegradable materials that are used in their construction. The present research gives an insight into the CPVC material moulding for electrical wire casing elbows using an injection moulding machine, which was previously unexplored. Four plastic injection moulding parameters were considered in order to reduce the weight of the elbow, including injection pressure, mould closing speed, mould pressure, and backpressure. The 27 tests were piloted in line with Response Surface Methodbased Box-Behnken Design, and the factors were optimised using Tunicate Swarm Algorithm, which was recently developed. In the case of the plastic injection-moulded item, the analysis of variance revealed that the most significant parameter in the weight reduction was the material used. It has been determined that mould pressure is the most critical factor impacting the weight of the item when it is manufactured. As a result, the optimum manufacture of injection-moulded CPVC components will be facilitated, resulting in optimised weight while also minimising production time and raw material waste for electrical wire casing.

An earlier paper ( 1 ) established the need for new compounding technology to deal with changes in melt flow resulting from the postchlorination of PVC resins. The present work attacks the more-than-doubled melt viscosity of chlorinated PVC as measured in stabilized resin. The potential for marked reduction in viscosity, improvement in processing stability, and retention of marketable product properties is explored. The development process including the definition of performance requirements, test methods used, and resulting balance of properties is described.

Lowell, M a s s a c h u s e t t s 01 854Comparative studies of melt processability showed that chlorinated polyvinyl chloride (CPVC) had low melt index and high Brabender melt temperature and torque, as compared with conventional rigid polyvinyl chloride (PVC). Of 3 processing aids at 10 percent concentration, triphenyl phosphate increased melt index 30-fold, fusion rate 10-fold, melt temperature 20°C. and torque 31 percent in CPVC. Two other processing aids, an acrylic and a styrene/acrylonitrile copolymer, were less effective. Improvements in PVC were less dramatic than in CPVC. Overall, use of processing aids made CPVC processability equal or even superior to conventional rigid PVC.
