Quality Control
Quality control (QC) is a procedural framework that encompasses various techniques to yield products of superior quality within the confines of a manufacturing facility. The assurance of goods and services being produced in accordance with established benchmarks or achieving all the desirable attributes of a product is accomplished through the application of quality control methodologies. Inspection constitutes a pivotal facet of this domain. In essence, quality control encompasses a series of operations, such as measurement or testing, which are conducted on a product or commodity to ascertain whether it complies with the prescribed specifications. The principal undertaking of quality control involves sampling products, scrutinizing those samples, and extrapolating the findings to encompass the entirety of the product, all of which is predicated upon statistical methodologies. An alternative approach in quality control revolves around regulating the production process rather than the product itself, and this is executed through the utilization of statistical methodologies such as SPC and others.
Fundamental factors affecting Quality Control
The principal aspects that have an impact on the caliber of goods and services encompass markets and consumers, financial resources, administration, technical components, labor force, incentives, resources, facilities, machinery and production techniques, cultural and educational technological level, domestic legislation, and quality control expenses
Quality control objectives
Maintaining and compliance set standards
Discovering and correcting process aberrations
Performance evaluation of units and staff
Production process Quality control (For preventive proceeding)
• In the manufacturing process, the product is tested after each step and send to the next step, if it has acceptable conditions. All product line documentation is archived and maintained to identify and track load shipments
• Finished product quality control:
• Before loading the products, daily sampling is performed and all tests are carried out on the final product and The qualitative and quantitative parameters of products are checked. Loading licenses are issued if they meet Iranian national standards
• process control
• Special studies during the process with the aim of finding the source of the main problems
