In manufacturing, quality control is a process that ensures customers receive products free from defects and meet their requirements. Inspection and measurement is needed during production for quality control because of the inherent variability introduced by the machines, tools, raw materials, and human operators which causes variations in the different quality characteristics (length, diameter, thickness, tensile strength, surface finish etc.) of the product. Inspection and testing is very important in maintaining a certain quality level in the product during production. It helps to control the quality of products by fixing the sources of defects immediately after they are detected. Several non-destructive inspection methods also help to perform in-service inspection to avoid any catastrophic failure and predict the remaining life of the product.

Quality Control (QC) is the process of ensuring that the quality of a product or service has met certain predetermined standards. Because it takes place after a product has been developed it often involves activities such as inspection or testing.
When a manufacturing facility has a good QC system in place, they will benefit in many ways. These benefits don't stop just at the manufacturing company, but extend to customers, vendors, employees, and more. The following are some of the key advantages...
When a manufacturing facility has a good QC system in place, they will benefit in many ways. These benefits don't stop just at the manufacturing company, but extend to customers, vendors, employees, and more. The following are some of the key advantages to having an effective QC system in place:
Customer Loyalty - Quality control helps to reduce the risk of a defective product making it into the hands of customers. Providing customers a consistently positive experience will improve their loyalty to the brand.
Reduced Waste - Being able to identify quality issues quickly will reduce the amount of waste produced due to defective products.
Compliance - In many manufacturing industries, there are compliance, environmental, and other regulations that must be met. QC programs can focus on these areas to ensure compliance.
Customer Referrals - Customers who receive consistently high quality products are more likely to refer their friends and family to that brand.
