Benefits of quality control

:



The need for quality control in factories is undeniable. The advantages of quality control are discussed below





1. Uniformity and stability of quality: As a result of quality control, uniformity and stability of quality is maintained. Because the product cannot be of low quality as a result of control at different levels of production. Apart from this, there is no unacceptable variation in the quality of different products. So quality control helps to maintain uniformity and stability of quality among products.

2. Reduction in cost of production: The cost of production is reduced by adopting quality control. This results in less production of bad or defective products. The main objective of quality control is to produce good products. The lower the number of defective products produced, the lower the cost of production.

3. Improved quality of raw materials: Quality control ensures uniformity in processed products. Because raw materials are inspected before processing, defective raw materials are excluded. As a result, the quality of raw materials improves.

4. Reduction of inspection costs: Quality control determines when, how much and in what manner inspections are to be carried out. Recommends only as many inspections as necessary. In addition, statistical quality control reduces inspection costs.

5. Eliminate unnecessary and non-conforming work: Quality control eliminates unnecessary and non-conforming work in the production of goods. Recommends performance of all activities required for product quality assurance. It also reduces the amount of quality control activities. It checks the quality of the product starting from the first stage of the production process till the last stage. If deterioration in product quality is observed at any stage of processing, then the product is unnecessarily withheld from further processing. So quality control helps in reducing unnecessary and inconsistent work.

6. Design and process development: Product design and process development can be done at low cost as a result of quality control. This is also a quality control advantage.

7. Development of technical skills: Quality control facilitates the development of technical skills and technology. Development of relationship between producer and buyer and quality control especially helps in development of relationship between producer and buyer. Buyers are generally satisfied for quality products and producers get good prices. If products of lower quality than the specified quality are supplied, the customer is generally dissatisfied. As a result, there is a possibility of deterioration of the relationship between the buyer and the manufacturer. It damages reputation and damages business. Therefore, quality control helps to maintain a good relationship between the producer and the buyer. Advantages of quality control: The need for quality control of products produced in industrial establishments. Generally, the following advantages are obtained from quality control: Undeniable.





Product quality control through various methods

1. Through quality control, one can find out the reasons for determining the product and take necessary measures to solve them. Factory inspection costs can be reduced by applying various methods of quality control. Through quality control it is possible to bring about the excellence of the products produced.

4. As a result of the application of quality control system, the variation in the quality of the product is detected in a very short time.

5. A proper quality control system results in fewer returns. Because the quality of the product is at a certain level. Quality control system makes product design and development easier. Because of the variation in quality levels, different national data are available, which help in product design and development in different ways. 6.

7. A quality control system reduces inspection costs, reduces time wastage and ensures better raw material utilization. As a result, the product quality is improved and the cost of production is reduced. Problems or limitations of inspection (Problems or limitations of inspection): Inspection has a special role in quality control. But inspection also has many problems. This problem needs to be solved before the inspection.





The problems are as follows

1. Problems related to the place of inspection 2. 3. Issues related to scope of inspections. Problems related to inspectors 4. Issues related to inspection costs and controls. 1. Issues related to place of inspection: Determination of place of inspection is an important issue. A specific place or places must be designated for inspection work. Different types of inspection should be considered when determining the location. The types of inspection are 2. 3. (a) Acceptance inspection (b) Inspection of work in progress (c) Final inspection (d) Inspection of machinery and tools. (a) Receiving inspection: Raw materials and products are inspected before entering the factory. All goods received are quantified and inspected. Such inspection may, however, be carried out by the seller at his premises before delivery of the goods. Such inspection is called pre-shipment inspection. If the inspection is done at the point of sale, the cost of returning the goods is avoided. 2. Issues related to quantity of inspection: Determining the quantity of products to be inspected is a complex problem. There are two ways to solve this problem. Namely (a) Inspection of all products produced i.e. 100% inspection. * (b) Inspection of some representative items of a lot called sample inspection. Even a 100% inspection may contain errors. Because the inspector is human and it is normal for him to make mistakes. Besides, 100% inspection is cost-effective. Inspection is likely to be defective due to illness of the inspector, broken and unsuitable inspection equipment, faulty measurements, improper use of inspection equipment etc. Apart from this, brittle products such as glass or plastic must be broken to measure their strength. In that case, 100% inspection means destroying all the products. For all these reasons, samples are inspected. Sample inspection is better in all cases where each single inspection is costly. However, sample inspections also have limitations. The advantages and disadvantages of both methods need to be considered when deciding how much to inspect.



3.Issues related to inspectors: Not every inspector may be qualified to inspect all types of products. Therefore, while selecting the inspector, one must keep in mind the multi-faceted qualifications of the inspector. That kind of inspection by the inspector. Trained and experienced for the work, he must be employed in such work. However, it is not available in reality. 4. Inspection Costs and Control Issues: Inspection costs are particularly significant in any manufacturing industry. Inspection does not increase the quality of any product. Inspection actually makes judgments about suitable and unsuitable products. Inspection costs are actually treated as indirect costs. Modern advanced inspection methods reduce inspection costs. Accurate inspection at low cost is desirable for every industrial establishment. Centralized inspection: Centralized inspection is an important step in quality control. Inspection is an important way or technique to ensure and control the quality of a product. The main purpose of inspection is to try to fix the quality of products by comparing raw materials, workmanship and manufactured goods with prescribed standards or standards. Accepting the good ones and discarding the bad ones is the job of inspection. The inspection process is followed at different places or at different stages of the factory. For example - raw material inspection, production process inspection, final inspection, post-sale quality assessment etc. Within all these inspection stages, 'Centralized Inspection' is included in the inspection stage of the production process. In this system, one or a few specific places in the factory. A few inspection centers or branches are opened. Finished products or semi-finished products are brought to this center for inspection. The advantage of this type of inspection is that the inspection equipment does not have to be dragged to different places and with a cold head. Inspector can solve inspection work very well. But bringing heavy goods or liquids or untransferable semi-finished goods to the inspection center is sometimes inconvenient.
