What does a quality control inspector do?
Following the Industrial Revolution and the rise of mass production, it became important to better define and control the quality of products. Originally, the goal of quality was to ensure that engineering requirements were met in final products. Later, as manufacturing processes became more complex, quality developed into a discipline for controlling process variation as a means of producing quality products. According to ISO 9000, quality control is the “part of quality management focused on fulfilling quality requirements.” In other words, it includes all the actions you take to verify that products match specifications. A quality inspection involves measuring, examining, testing, or gauging various characteristics of a product and comparing those results with specified requirements to determine whether there is a conformity. Quality Control is critical to build and deliver products that meet or exceed customers’ expectations.
I like how you said that an inspector can help you notice any defects on the job done. I will suggest to him to contact a material testing company so that they can grade the quality of the job and material. It’s great that you mentioned that being able to have the inspection before will save you from costly damages or issues in the future.
Quality Assurance vs. Quality Control Resources
Mass production established processes for the creation of parts and system with identical dimensions and design, but these processes are not uniform and hence some customers were unsatisfied with the result. Quality control separates the act of testing products to uncover defects from the decision to allow or deny product release, which may be determined by fiscal constraints. For contract work, particularly work awarded by government agencies, quality control issues are among the top reasons for not renewing a contract. The first two parts focused on the different inspection levels and on the AQL tables.
In practice, projects typically have a dedicated quality control team which focuses on this area. “The relevant standards give no indication about when to switch inspection https://www.globalcloudteam.com/ levels, so most importers rely on their “gut feeling”. If the supplier refuses to disclose the factory information, you have to go for a final (pre-shipment) inspection.
Quality Control: What It Is, How It Works, and QC Careers
The 100% inspection method calls for data about the manufacturing process and software to analyze inventory. The food industry uses quality control methods to ensure customers do not get sick from their products. The final and crucial step in the quality control process is packing up the new product and properly preparing batches for shipping to destination markets. This is the last opportunity for inspection before your products reach your customer. Quality control inspectors usually perform on-site DUPRO inspections when about 20% of the batch has come off the production line. If an issue is found at this time, it may be possible to find a workaround to fix the defective products and/or make necessary adjustments to the manufacturing process.
- The first two parts focused on the different inspection levels and on the AQL tables.
- QC ensures engines, drive trains, and other mechanical parts operate smoothly, efficiently, safely, and as designed.
- An alternate definition is “the operational techniques and activities used to fulfill requirements for quality.”
- Here, teams evaluate the raw materials or products sent along your supply chain.
- To avoid creating delays, inspectors can usually start after all products are finished and 80%+ of the shipment quantity is packed.
If this is a standard product and you have flexibility with timing, a final (pre-shipment) inspection should be enough. A solution is to select samples at random and inspect them, instead of checking the whole lot. Lab testing is often essential to ensure regulatory compliance and may be required for your product. For example, if you import children’s products into the United States, you must test them to comply with CPSIA regulations. You can prevent the low-quality or substandard products from reaching the customers, which will reduce the complaints.

With that in mind, I will make sure that my mother will be having her products inspected before releasing them. She just created a makeup line since she has been very fond about these things ever since she was a teen. For eg as per AQL 2.5 we take 80 pcs for quality inspection , out of 80 how many pcs we need to check for measurement. Read and clip the slides for the above video on the product inspections here. Depending on the level you choose, the inspection might take only one inspector for one day, or up to 4 or 5 days of work. The inspector compiles an inspection report, which includes notes, pictures of your product, and tells you whether or not the goods passed inspection.
Quality Control consists of the actions taken to ensure that the quality of manufactured products is high, consistent, and up to predetermined standards. These measures aim to identify errors and verify that products adhere to specific product criteria. They are important because, ultimately, they enable you to please your customers. Great quality control also provides essential feedback that can help you drive continuous improvement in your manufacturing processes. What this difference means for quality professionals is that as you move through a quality control career, you might transition from quality control to quality assurance. Quality control inspectors, also called quality controllers are members of a control audit team that examine manufacturing processes and operational techniques.
What does a Quality Control Inspector do?
If you have any questions about the topics we’ve covered, feel free to comment below. Pre-production Inspection – These take place before the factory starts production. They can help you check a prototype, verify that raw materials are high quality, or ensure the factory is ready for mass production.
It will also help them streamline and modify the existing inspection processes and practices. Acceptance sampling is a statistical quality-control measure that lets a company determine the quality of a product lot by testing randomly selected samples. The Taguchi Method of quality control is another approach that emphasizes the roles of research and development, product design, and product development in reducing the occurrence of defects and failures in products. The Taguchi Method considers design more important than the manufacturing process in quality control and tries to eliminate variances in production before they can occur. Randomly selected products are tested for the given attributes the chart is tracking.
In addition, many non-destructive inspections can be performed by a precision scale, or when in motion, a checkweigher. Stereo microscopes are often used for examining small products like circuit boards for product defects. Inspection and measurement of the thickness of the different layers of an electronic chip using THz and X-ray radiation.
Quality control experts visit factories on behalf of customers to ensure the manufacturing process and products meet the standards agreed upon before the merchandise leaves the factory. Quality control services include on-site factory inspections and testing with detailed reports to help ensure that your products meet your specifications and manage product quality in your supply chain. Quality “check” is the most important and basic function of quality inspection.
The Pre-shipment Inspection Guide and Product Quality Assurance
Most manufacturing errors are easier to fix during production than when goods are completed. One of the main aspects of quality control is that there must be well-defined quality control standards, https://www.globalcloudteam.com/glossary/inspection/ known as the quality control process. 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.
