摘要：PT. XYZ is a company in the field of industrial manufacture of PVC pipe (Poly Vinyl Chloride). Pipe products produced often have a disability are not standards-compliant (5,5%) and exceeds the tolerance (±1%), which has been set by the company. Competitive competition in product marketing lead companies needs to boost quality. The importance of quality is one of the reasons to research the quality of products produced by the company. This study using method seven tools and taguchi to analyze and improving the quality of pipe. Seven tools method used to identify factors that influence product defects. Taguchi method produces the optimum combination of factors that influence the level of significance is the coolant temperature 20 ° C at level 2, extruder temperature of 150 ° C at level 1, haul off the speed of 18 m / s at level 1 and a pressure of 0.06 MPa printing at level 1.
