How to Conduct Quality Control Management?

How to Conduct Quality Control Management

 1. Understand the Value of your Products

With the product value in mind, you can figure out the quotes from factories which may help you settle on the domestic consumers.

You have to figure out the raw material, basic process, functions, and even the design. The most important thing you have to understand is about product quality.

You have to know the price range of the product at a certain level of quality.

As such, you have to understand the value of the product and differentiate which are the low quality ones.

The full understanding of your products will definitely help you to specify the quality standards in detail in the contract when you cooperate with Chinese manufacturers.

3. Inspect the Imported Products

When it comes to quality control over the imported products, there is a wide variety of stuff to do on the list.

It covers all possible links ranging from the beginning of the manufacturing line and the ending of pre-shipping management.

We’ve divided it into three different periods for the product.

It is the first step in checking the raw material and components to manufacture your goods. Generally, Chinese factories are inclined to source lower price materials and might be unaware of your country’s restrictions.

For instance, countries from the Asia Pacific and Europe might have different limits.

To ensure quality, you could draw samples randomly for lab testing. Besides, you should check the product prototype to ensure a successful design.

In addition, you have to make frequent communication before the mass production period. 

These ensure that the Chinese factories completely understand your quality specifications, materials, components, and manufacturing process.

  • In-process Inspection

In-process inspection means the inspection during the mass manufacture of products. It is to prevent that they produce possible unsellable products. 

You have to check the quality of a few manufactured products. It is vital to correct them early and avoid issues before you manufacture the rest of the products.

You should never check it too early or late given its turnover of the product manufacturing.

Try to find out the non-conformity products based on the buyer’s requirement.

Besides, you have to pay attention to the visual defects of the products. This step is of great importance before it enters the market. 

What’s more, you should monitor the Chinese manufacturing process, like the forging process and the assembling requirement.

Communicate frequently to ensure your Chinese supplier understands your product specification better. It allows you to get the manufacturing update from the factories too. 

Most Chinese factories produce nearly up to the required standards.

The in-process inspection prevents possible loss for the “almost” attitude. You also have to pay attention to your intellectual property and schedule to know the lead times.

Remember to follow up on these critical issues for your business and make necessary changes based on the market.

  • Pre-shipment Inspection

Literally, pre-shipment inspection means the product inspection before the shipping. Typically, you will get quality control from the Chinese factories on finished products.

But that’s not enough. It is usually carried out once 100% of the order is produced and almost 80% packed.

Some may even wait until all orders get packed. It identifies possible faults and errors before shipment to ease issue correction.

For this part, you may not be able to check the product one by one. The best solution is to make onsite sampling tests to determine the acceptable number of defects.

Pick randomly, and figure out an accurate overview of the quality of the batch order.

Then, get the test report, and evaluate if it is up to your quality standards.You should pay close attention to finding the defectives.

The possible problems are the products, dimensions, and unmatching color from the ordered samples.

You may also find scratches, holes, and other damages.

4. Choose an quality inspection method

It’s important to entrust a reliable partner to conduct quality control and ensure good product sourcing.

As such, you can make it by yourself, hire inspectors, or authorize a professional quality inspection agency. Make sure they fully understand your product requirements.
