The current era can be called the era of quality. In such competitive conditions and with mass production, only manufacturers can be successful in providing higher quality products and better after-sales services. In fact, quality control has become one of the main considerations before manufacturing any product. Better quality control leads to better productivity of available resources and lower production costs.

 

One of the most difficult tasks in the product production process is to bring the products to the appropriate quality level and continue their production at the same level.

To achieve quality control, various measures must be taken, some of which are:

  1. The desired product must have a minimum quality level so that it can be easily sold in the market.
  2. In order to evaluate the quality level of the product, strict standards must be used.
  3. Deviation from a reasonable standard with respect to predefined standards should be determined.
  4. The appropriate quality level of the product should be obtained in such a way that it is associated with the lowest cost for the production of that product.

In fact, quality control concerns product quality control during the production process. In other words, quality control controls the negative variables that adversely affect the quality of the final product.

Although it can be said that the history of quality control is the same as the history of industries and inventions, and since the day when humans began to make the tools and equipment they need, they have always sought to improve their quality, but this matter was not discussed until the time of the revolution. Industrial and mass production was not taken very seriously and still, except for the few advanced industrial countries such as Japan, America and England, it is not given much value in practice, except for the countries that are forced to use it to export their products.

However, the quality control of raw materials, semi-finished materials, and of course the final product in the production process of the product is of great importance in the production process, and no product will be delivered to the customer without passing the formal quality control processes of the quality control unit and the collection laboratory. Also, all the raw materials required for the production of the final product will be controlled in several stages according to the regulations approved by the Food and Drug Organization and the related manufacturing permits, and then will enter the main production line of the Rangineh Naqsh complex. These processes will finally ease the mind of the customer and the final consumer due to the smallest health and technical problems.
