Quality Control and quality inspection are essential aspects of the quality control system. Though the two may seem like the same, there are significant differences between them.
Quality control is a company’s process to maintain quality throughout the entire production process. Manufacturers must create an environment that ensures products are manufactured up to a specific standard. Quality Inspection is part of the quality control process for inspecting the manufactured products to ensure they are up to the required standard.

What Is Quality Control?
Quality control is a process to ensure that product quality is maintained or improved. The key is that quality control is about the entire process a product must go through to ensure that the product is up to standard.
Quality control requires that the manufacturer create an environment where employees and management will strive for perfection in manufacturing products.
For example, at Mondoro, one of our core values is “Zero Complaints and Defects” We strive to ensure no complaints or defects in our production and manufacturing process.
We do several things to ensure that we have Zero Complaints And Defects; all of these things have to do with quality control.
- Training Personnel – We spend time to ensure all our employees and also stakeholders are trained in quality and understand all the quality standards we have in place.
- Benchmarks for Product Quality – We also set a standard and have a benchmark for what those standards need to be for all the items we produce. We do this by ensuring we have all the proper paperwork and other things in place as part of our quality control process.
- Test Products – At Mondoro, we do various in-house testing for our products. These tests include drop tests, UL electrical standards, cycle tests, and rust and other metal tests. We have testing guidelines to ensure that our product meets the required standard.
One of the main aspects of quality control is that there must be well-defined quality control standards, known as the quality control process.
These quality control standards are in place to help standardize the production and how the manufacturer will react to quality issues that may arise.
One of the aspects of quality control is to have a well-defined standard for when quality control issues arise and what employees can handle what aspect of the quality control issues—having a process in place of who can handle what standards also helps to ensure that only the people who are qualified can help to solve quality control issues.
What Is Quality Inspection?
A quality inspection is part of the quality control process in place. A quality inspection has several vital functions that include:
- Measuring – An essential aspect of quality inspection is to measure the products. This can be from measuring the size to counting that all the quantity is present and ready to be shipped.
- Examining – Examining is about looking at the product’s overall quality and all the product quality details. At Mondoro, we do a 100% inspection to examine all the products while in the production process and the product’s final quality.
- Testing – Testing ensures that products are up to the required standard. At Mondoro, we will do drop tests for packaging and electrical testing for all lamps. We have other standard tests we do as rust tests for metal parts, cycle tests, and weight limit tests.
- Comparison – An essential part of quality inspection is to compare the products against a sample and other information. At Mondoro, we have product forms and other information that help to give us quality characteristics and benchmarks; we require that we also have production samples so that we can produce them as per the confirmation sample.
At Mondoro, we have several types of inspections that we will do to ensure the quality of the products. The inspections are part of the quality inspection process:
- DUPRO – During Process Inspection – This is the inspection that takes a place during the production of the product. It can include two kinds of inspection:
- Preproduction Inspection – Preproduction Inspection takes place during the preproduction phase when raw materials will be examined, checked, and tested.
- In-Process Inspection – In-process inspection is when we inspect the goods or products manufactured. During this phase, we will measure, examine, test and compare the products throughout the production process.
- Preproduction Inspection – Preproduction Inspection takes place during the preproduction phase when raw materials will be examined, checked, and tested.
- FDI – Final Detailed Inspection – The Final Detailed Inspection is also known as the FDI is the inspection that takes place when goods are packed and ready to be shipped.
Quality Control Vs. Quality Inspection
Both Quality Control and Quality Inspection are essential processes to ensure that the goods are of the required quality; they are both focused on the quality of the product.
Quality Control is about the entire quality process and the training of personnel, testing, and other aspects of quality that ensure that a product can be produced with zero defects or complaints. Quality Inspection is under Quality Control and is only one aspect of the entire Quality Control process.

: Quality inspection focuses on identifying defects or discrepancies in finished products, whereas quality control encompasses a broader range of activities to ensure that all manufacturing processes meet specific quality standards.
What is the difference between quality inspection and quality assurance?
: Quality inspection is a subset of quality assurance. While quality inspection focuses on identifying defects in finished products, quality assurance encompasses a broader set of activities to prevent defects and ensure that processes are implemented correctly throughout production
What is the difference between quality control and quality inspection?
Quality control involves the entire process of monitoring and managing product quality, including inspection. Quality inspection specifically refers to the examination of finished products to identify defects or deviations from quality standards.
How does inspection differ from quality control?
Inspection is a specific activity within quality control that involves examining finished products for defects. Quality control encompasses a broader range of activities, including process monitoring, documentation, corrective actions, and continuous improvement to ensure overall product quality
What is the primary purpose of inspection in manufacturing?
The primary purpose of inspection in manufacturing is to identify and address any defects or discrepancies in finished products before they are delivered to customers, thereby ensuring the product meets the required quality standards.
How does quality control ensure product quality beyond inspection?
: Quality control goes beyond inspection by implementing processes, procedures, and quality standards throughout all stages of manufacturing. It includes activities such as process control, quality audits, supplier management, training, and continuous improvement initiatives.
