Quality Control

Quality control, also known as product verification is a process to check the status and quality of your goods, during all steps of production in order to ensure that you will get what you ordered.The quality control will help you to make sure that all your requirements, specifications and criteria you have given to a factory are being taken into account and implemented properly.

The quality controls are usually performed according to international quality control standards such as ANSI/ASQ Z1.4-2008 but we also perform quality inspections as per your instructions and criteria and according to our expertise and long experience. The ANSI/ASQ Z1.4-2008 standard is equal to the national and international BS6001, ABC105, ANSI/ASQ Z1.4, NFX 06-022, MIL-STD-105E´╝îISO 2859-1and DIN 40080.The advantage of ANSI/ASQ Z1.4-2008 standard is that it can provide a specific sampling number in the given batch, and also confirms the maximum amount allowed of defective goods. 


The quality control include below parts:

1)Pre Production Inspection

2)Earlier Production Inspection

3)During Production Inspection

4)Pre-Shipment Inspection

5)Container Loading Supervision


Just as there are many steps in the manufacturing process, there many opportunities for inspections during the process. Which specific inspections you need depends on the nature of your product and your level of risk tolerance.  The figure below shows the flow of inspections.

As a general rule, the later in the production process an inspection is done, the higher the risk of delay and cost because a higher volume of product has to be re-manufactured. 

The Risk-Cost tradeoff curve looks like this:

This curve show us two things:

·      the sooner in the process errors are found, the lower the cost to recover from the errors, and

·      we can lower risk but doing the proper inspections at the correct time.


When a company skips the earlier inspections and uses the Final Random Inspection as its only quality check, the cost of an error is many times more than the cost of the earlier inspections would have been.  While this strategy may work for a factory one has been dealing with for some time, making the same product, it really is not advisable when working with a new supplier or on a new product with an existing supplier.
