Introduction The progressive development of technology results in an increase in the load of used machinery and equipment, which contributes to the increase in requirements for construction materials. This development concerns the emergence of new technologies for manufacturing metals and their alloys, which have better strength properties, Budzik and Jaskólski (2004); Zima (2005); Pacana et al.

Quality control points used in an industrial enterprise manufacturing oil pans for heavy vehicles are discussed. The study aimed to present a proposal for a method for analyzing the effectiveness of individual control methods used as part of quality control in the manufacturing process of a product and to analyze the relationship between the type of quality control methods and their contribution to the detection of nonconformities of the product - an oil pan. By locating the control point with the highest share of product nonconformity detection, it is possible to take improvement actions - reducing control points by less effective ones. This action will contribute to cost reduction and shortening of the production process time. Due to the increasing demands on the efficiency and effectiveness of control points of automotive powertrain components, this issue is important and topical. © 2021 The Authors.
