What are the most effective quality control and assurance tests for manufactured products?

Handling of MATERIALS from warehouse to finished product in the process of shoemaking is most important. Others are all SECONDARY.

Yes, This is the first criteria for a QC. And it also depends on the individual identification power that he captured on his mind while processing these tests.

Imagine it like giving your product a close-up look – that's visual inspection, a super common quality test! It's all about eyeballing the product for any issues, like defects, damages, or things not matching the design. Humans can do this manually, or machines and cameras can do it if there's a lot to check. Think of it like a product health check. Visual inspection spots things like cracks, scratches, dents, or missing parts – the kind of issues you want to catch early. If something's off, you can either say no to the product or fix it up. It's like having a keen-eyed superhero making sure your products are top-notch!

Instead of implementing visual inspection at the end of a line or process , visual inspection can be implemented in the form of automated machine controls or manual checklists or records at every stage of process / operation to prevent the defect from reaching the next stage, which in turn will reduce the time wasted in subsequent process / operation and reduce internal customer voice . But visual inspection by manpower is time consuming and is difficult for large volumes, while automated inspection make require initial capital and frequent checks to ensure the effectiveness of the inspection. Personally certain areas concerning safety, fitment and aesthetics may require manpower intelligence and experience gained from previous results.

I have done visual inspections countless of times, and when it comes to keeping in mind the safety of the people, working in the automotive industry, there are many guidelines, standards and tools implemented for this inspection as well. With any inspection, there is always the possibility of the person's own interpretation, whether a product has a visual defect or not therefore it is very important to implement clear guidelines, detailed work instructions and proper tools in order to ensure quality. A detailed list of possible defects the worker should look for, have an Inspection Cabinet with the proper lighting conditions, have the worker properly trained on using this and other tools aiding the visual inspection.

In my experience, Dimensional measurement is very important check for your products – it ensures they're the right size, shape, and geometry as per the specs. Tools like rulers, calipers, micrometers, and fancy machines (Coordinate Measuring Machines or CMMs) come into play. Picture it as making sure each piece of the puzzle fits perfectly. This measurement isn't just about looks – it's the superhero move to guarantee your products not only look good but work just as they should. It's like having a precision superhero guarding your product perfection!

In my experience, Functional testing is like the superhero challenge for your products – it goes beyond the basics to check how well they perform in various situations. Using methods like electrical, mechanical, thermal, or environmental testing, it's like putting your product through different tests. Imagine it as making sure your superhero can handle any kind of weather or challenge! This testing helps you know if your products are reliable, durable, safe, and compliant. It's the superhero move to spot and fix any issues before they become problems. Functional testing is like having a superhero mentor for your products' performance!

This is the oldest, original, and best predictor of success/failure of a component or subassembly. Actually, before tolerances were invented, everything was tested functionally. Functional testing may not happen until late in the manufacturing chain, however. This means the cost to produce the component or subassembly to that late stage is high. If a non-functional component must be scrapped, it will be more costly. Re-work expenses, if possible, are typically high as well. Another difficulty of functional testing is figuring out why something failed, as there are many components or dimensions in the subassembly. Therefore, Functional testing is best done as early as possible in manufacturing chain.

“Customer Listing should be done effectively which will let you learn the sensitivity on tolerances to their products.” What I believe among all tests, destructive is the only way which will unlock the assurance confidence to confront your customers because at the end, technical factors where you can standout make their believe turn. Advantage’s lies are: * Core knowledge in technical terms. * Excess to statistical product behavior. * Alteration in operations will easy. * You’ll always one step ahead when comes to assure your customers. * You’ll be valued by your stakeholders. * Rejection & rework will eliminate. * CRM will improve.

Destructive testing is checking soundness and integrity for your products – it involves breaking or damaging them on purpose to see what they're made of. Picture it as giving your product a superhero workout! Using techniques like pulling, squeezing, bending, or even hitting, it's like a superhero facing different forces. This testing helps you figure out how strong, tough, hard, or resistant your products are. It's the superhero training to make sure your products meet the highest standards and expectations. Destructive testing is like having a superhero push your products to their limits to ensure they can handle anything!

Non-destructive testing is checking soundness and integrity for your products – it checks them thoroughly without destructing them . Imagine it as giving your products a superhero health check-up! Using methods like visual testing , ultrasonic, magnetic, radiographic, or infrared testing, it's like the superhero's special tools to see beyond the surface. This testing helps you spot any hidden issues, defects, or cracks inside your products. It's the superhero move to make sure your products are of top-notch quality and stay intact. Non-destructive testing is like having a superhero with X-ray vision ensuring your products are healthy from the inside out! ??

Non-destructively testing (NDT) is a quality control technique which focuses on defect identification. The technique utilizes a string of technology to identify defects without impairing the usefulness of the manufactured product. The basic NDT methods include Visual Inspection (VT), Penetrant testing (PT), Magnetic Particle Inspection (MPI), Ultrasonic testing (UT), Radiography Testing (RT), and Eddy Current testing.

The quality control and assurance of manufactured products depend on type of manufacturing, but by following the ISO procedures which considered general for any manufacturing, each process has a steps of products and we need to do control and inspection for each step of process, by this way we can control . Otherwise all the step it was written previously in Quality Assurance procedures .
