• ### SPC application in the chemical industry

Publication Year: 1990, Page(s):4/1 - 4/2
| |PDF (48 KB)

The paper outlines issues that arise in applying SPC to the continuous processes of the chemical industry, including: process complexity, process variability; and product analysis. The paper also considers activities necessary for implementing SPC and the benefits of introducing SPC in chemical processes, particularly the processes at ICI Chemicals and Polymers View full abstract»

• ### Practical automation of statistical process control for injection moulding

Publication Year: 1990, Page(s):3/1 - 3/3
| |PDF (108 KB)

A catastrophic process failure can be detected by local trips on the machine. The trip-limits should be set wide enough to allow for the cycle-to-cycle variation inherent in the process without tripping-out. However they cannot detect marginal process failure until it reaches catastrophic proportions. Statistical analysis of product and process is not only essential to detect marginal process fail...

• ### Experiences of introducing SPC in a confectionery factory

Publication Year: 1990, Page(s):2/1 - 2/2
| |PDF (72 KB)

As part of a drive towards improved quality and enhanced performance at a confectionary factory it was decided that SPC techniques would be introduced. The aim was to bring a degree of objectivity to assessing processes and activities that were considered to be difficult and unpredictable. Using the data generated, potential improvements would then be sought and implemented, and the outcome statis... View full abstract»

• ### Statistical process control: practice and benefits

Publication Year: 1990, Page(s):1/1 - 1/3
| |PDF (160 KB)

Statistical process control (SPC) is based on the control chart techniques which were developed by W.A. Shewhart in the late 1920s. There has been a renewal of interest in these techniques in the last decade largely due to the influence and example of Japanese quality management practice. The aims of SPC are to eliminate scrap and rework, to manufacture products right first time' and to continuou... View full abstract»

• ### Statistical process control-the British Sugar experience

Publication Year: 1990, Page(s):5/1 - 5/5
| |PDF (216 KB)

British Sugar has a long history of using statistical process control (SPC) in the control of product weights but has only, in the last three years, used the technique within the manufacturing process itself. In the 1988-9 beet processing season, SPC was introduced at the Peterborough plant using it as a test bed. Several valuable lessons were learnt from the trial, lessons which made the implemen...

• ### On-line statistical control of production lines

Publication Year: 1990, Page(s):6/1 - 613
| |PDF (468 KB)

The advent of microprocessors has enabled the whole process of data collection, analysis and responses to be implemented faster and more efficiently than the traditional methods, with consequent savings in product and labour. MCI Systems have developed a suite of computer programs to automate this process and thereby control and monitor various aspects of the filling line. The paper reviews the ba... View full abstract»

• ### Statistical process control of continuous chemical processes

Publication Year: 1990, Page(s):7/1 - 7/4

| |PDF (172 KB)

The increasing demands for improvements in product quality and productivity of chemical processes has led to a heightened interest in the application of statistical process control (SPC) techniques in process industries. It was shown, in many cases, that the existence of conventional process control loops, based upon empirical considerations, was not enough to improve/maintain the quality of the p...
