Abstract
In manufacturing world demand of hollow plastic product is increasing which are mainly produced by Plastic Rotomolding Process. To produce better qualitative product, some operating parameters and its composition plays important role. By using ANOVA method, we get the most significant factor. Study describes the factors rotational speed, cooling time and oven temperature as operating parameters that produce better product in terms of tensile strength. Low density polyethylene was considered as polymeric matrix produced by bi-axial turret plastic rotomolding machine with the sets of different rotational speed, cooling time and oven temperature decided by design of experiments according to the L16 orthogonal array of Taguchi approach. Tensile-test of workpieces is done with Tinus-Olsen-H10KTUTM. Water tank gets optimum quality by having compositions of parameters, with the help of ANOVA and Taguchi methods. The result of study suggests for both academia and industrialist to consider the correct factors with their specific limit while manufacturing in plastic rotomolding process for achieving better quality of product.Keywords- ANOVA, Taguchi, LDPE, Rotomolding process.
