Abstract

Enterprises need to develop an appropriate quality management approach in order to produce conforming products. This project deals with quality concepts and tools which are mainly adopted by small and medium size enterprises. It is widely accepted that Statistical Quality Control (SPC) involves several methods and tools that can be used in order to examine and solve a wide range of quality problems.

SPC tools are implemented in a company operating in the Greek plastics industry. The charts used to plot the data collected indicate the existence of special-cause variation. A cause-and-effect diagram is used to assess the contribution of several factors provoking variation in the production process. A process capability study is conducted after eliminating the samples plotting out of the specification limits. The study indicates poor capability and suggests using more effort in improving quality performance.

Extensive reference is made on an SPC implementation process, while management commitment, training and teamwork are highlighted as the most critical factors to SPC successful introduction. In addition, the ASTM D882 is presented as one of the most sophisticated methods regarding the determination of polymers tensile properties. It is expected that both SPC and ASTM D 882 can contribute in establishing a more sophisticated quality management approach which will be strongly based on the use of statistics.
