| In recent years, with the rapid development of UV-curing industry has achieved in the electronics industry, household appliances industry, building materials in the fields of application. There is a optical polymer transparent plastic, because of its like glass of optical properties and won the favor of the market. But its low surface hardness, scratch resistance is poorer, need through to the surface of UV light curing coating processing, make the material surface hardness and scratch resistance improved. In the process of coating processing, its often can produce because of bubbles, solid impurities, uneven surface of point defects, scratches and bad appearance of flow lines, etc. Therefore, in order to guarantee the stability of the hardening coating needs continuous quality improvement.Taking J company as an example, the optical surface coating treatment on PC material to study the production of quality improvement. First of all, J company is a professional engaged in the multi-function coating composite materials research and development, production and sales, is a leading domestic multifunctional coating composite integrated solution provider. As the change J company address in the June 2015, optical plastic surface hardening treatment of curtain coating production line also will move, however, after the relocation from July, when it formal production, the quality of instability for up to four months. Secondly, through the analysis of the quality management of J company is currently the status quo, found that the problems there are external and internal quality management. Then, in the meantime with the introduction of six sigma management method, using DMAIC management tools and methods, actual test data collected and sorted, find the bad reasons of unstable product quality, improve product quality of production. Hope that through the introduction of six sigma management method, explore to applied optics plastic surface treatment methods of production operations management, and meet the increasing market and customer requirements. |
