Analisis Pengendalian Kualitas Bahan Baku Acrylic Resin Pada Produk Spray Paint di PT X
Thermo Plastic Acrylic resin has an important role in the manufacture of spray paint, namely as a binder or binder. The resin in paint has a function as a film formation, has adhesion to the substrate as well as pigment binders and additives, so that to produce a spray paint with good quality mechanical properties, PT X must be selective in controlling the quality of the raw material for Thermo Plasic Acrylic Resin. The purpose of this study was to determine the problems faced by PT X related to the quality of Thermo Plastic Acrylic Resin raw materials, to identify the most dominant factors affecting the quality of these raw materials and to formulate the most appropriate solutions to be applied in improving the quality of these raw materials. This research uses observation, interview, and literature study methods. Sources of data came from stakeholders and quality control staff of PT X. This study used check sheets, histogram diagrams, u-control maps, and fishbone diagrams to complete the analysis process. From the test results of the Thermoplastic Acrylic Resin raw material, it is known that the factor that causes rejection is due to adhesion, namely 53.57%, gloss 33.33%, and dry touch 13.10%, all three of the total raw materials that are rejected when the raw material is applied in form paint and spray on the film plate. The most dominant cause of reject was poor adhesion, namely 53.57% of the total reject raw materials.
