Types of Inspection in Quality Control Services
There are many different types of inspection in quality control services. We have listed nine of them below.
1- Pre-Product Inspection
This is the most common type of inspection. It is performed to check whether there are defects in the material before it is sent to the manufacturing process. This can be critical in ensuring that all the raw materials are high quality. Therefore, you don’t incur any losses when it is delivered to the manufacturing process.
During this inspection, the inspector has to visit your supplier’s site to check the quality of materials used in the manufacturing process. Also, he must inspect all the components and raw materials to ensure no defects are present.
2- Sample Checking
Sample checking is an important type of inspection. It is non-destructive so that you will not lose the entire lot before the manufacturing process starts. Sample checking is key to ensuring the quality of your finished product.
It is also very useful when your products have conscious or unconscious errors after manufacturing them. The sample checking is performed using different techniques in various industries. The techniques include using human senses, X-Ray, microscopy, etc.
3- Statistical Process Control
Statistical process control is widely practiced in quality control services. It is performed to measure the process capability of the manufacturing process. It will also help ensure that there are no changes in the quality of your product. This type of inspection is generally carried out continuously throughout the manufacturing process.
Various types of testing are used to evaluate the quality of your product during this. For example, you can use artificial intelligence, statistical methods, and software to measure the quality of your product.
4- In-Process Inspection
In-process inspection is also known as throughout inspection. This inspection ensures that your product is still in good condition throughout the manufacturing process. And no defects are appearing on it till last.
It can be considered as a combination of pre-product and in-process inspections. Some big companies and organizations generally do this type of inspection on high-value products such as electronics, pharmaceuticals, etc..
5- Final Inspection
This inspection is performed on your products after the manufacturing process ends. It is mainly used to check whether there are quality issues with the finished goods. So if any defects are present, you can rectify the problem before it goes to the market.
It is also referred to as the final test and final acceptance inspection. This inspection is critical because it can decide whether you will rework your product or issue a rejection notice on it. At this point, you can use all the high technologies to find out whether your product meets all the quality standards of your organization or not.
6- Maintenance Inspection
A maintenance inspection is very useful when manufacturing products considered to be low in value. For example, if you are manufacturing chemicals, the maintenance inspection is done to ensure that the chemical doesn’t go out of specification.
The maintenance inspection is performed periodically throughout the manufacturing process by specialized inspectors. They visit the plant and analyze the quality of different operational parameters such as temperature, pressure, etc.
7- Unit-Integrated Inspection
This inspection is used to check if all the units are working properly and if there are no quality problems. This inspection, also known as in-line inspection, involves performing various tests on a certain number of units simultaneously.
This inspection is especially useful when you see some defects in a few units. After that, you can rectify the problem immediately before it appears on many other units.
8- Reliability Inspection
Reliability inspection is also called product surveillance. In this type of inspection, your products are tested to ensure that they meet the quality standards of your organization or not. This inspection is generally performed periodically throughout the year.
Contractors carry out the testing, and you must provide them with full documentation about your product and its specification. If your product meets all your organization’s quality standards, you will get a certificate to prove it.
9- Sorting Inspection
This type of inspection is only performed when the manufacturing process ends. It is used to check the quality of your finished product and decide whether you are going to sell them or not.
This inspection ensures that your product had no defects during the manufacturing process. The quality defects that cause rejection of finished goods are missing, defective, or broken.
