Quality inspection is an integrated procedure by which organizations assess the quality of various factors involved in manufacturing. An organization that does not practice quality control has no business. Quality control is the corner stone of any business and the entire process of quality assurance begins with it. By definition, quality inspection is "the process whereby a company assesses the quality of aspects involved in the manufacture of goods, such as quality of raw materials, quality of finished goods, and standard procedures applied to manufacturing processes." ISO 9000 also defines quality inspection as "an aspect of quality management related to the realization of quality standards in the commercial world".
Quality inspection has emerged as a major tool for quality management in most industries. It helps meet the varying demands of purchasers, implement usage decisions correctly, and improve overall performance. To facilitate the inspection process, many organizations today use software offered by the GlobalVision for quality inspection.
The inspection lot is divided into three different phases, namely Pre-Treat, Tolerate and Post-Treat. During the first phase, the whole manufacturing process is analyzed to understand the root cause. Analysis of the system leads to the identification of weaknesses and the correction of these faults. After this the second phase starts where the flaws are observed in every piece and then corrective actions are taken to avoid similar occurrences in the future. During the last phase of quality inspection process, the system is checked once again to find any errors and then all components are tested to their limits to ensure compliance with the product specifications.
Many companies have developed special systems to support quality inspection. Some of the commonly used inspection packages include the MAST Education System, NSTD, RDSS, and the SIEB Certification. Each of these systems provides guidelines to help quality inspectors implement reliable quality control procedures in the production process. Most of these software packages come with a statistical processing library that helps in the analysis of plant inspection results. Some tools like NSTD generate the statistical output for the entire or a specific portion of the production process. Click here for more info about quality inspection.
The accuracy of the statistical process control depends largely on the skill of the inspectors and their adherence to standard operating principles. Thus, it is important to hire only those inspectors that meet the quality standards. One should always prefer using specialized services for high value products that are more complex to test. The choice of analytical methodologies greatly influences the performance of the quality inspection.
The statistical process control tools and techniques can significantly improve the production process and can help in producing more efficient, effective and cost-effective goods. However, proper understanding of the product as well as its specification are essential to employ quality inspection. It is important to review the quality history of the product to identify any past defects. It is equally important to conduct an effective quality inspection.
