Quality control over grading is important to ensure that products are able to deliver the performance that designers expect. This applies equally well to appearance grading and structural grading. In-grade testing of structural products can be used to verify structural properties.

Hongming rigid box machines produce their own quality control systems and manuals and in some cases seek endorsement for their quality system under ISO 9001.

In some cases, third party auditing of the quality control systems can be used to issue a product certification. This gives potential purchasers confidence that the quality control and assurance programs are in-place and functioning well.

The main process affected by quality control techniques is the grading operation. In-grade testing is the ultimate test of the effectiveness of any grading operation.  There are two types of quality control that can be applied:

•        Process Control – checks that the process is being conducted in the way that will produce material of consistent quality.

•        Product checking – looks at the output from the process and establishes whether or not the properties of the product are consistent and within the specification for the product. It picks up things that may not be detected in process control, such as variations in raw materials. This primarily uses the process of “in-grade testing”.

Processing and production equipment: we have imported the most advanced processing equipment in the world: such as five-sided gantry processing center from Germany, dozens of high-precision machining centers, precision grinders, milling machines from Taiwan to ensure our machines’ structure and spare parts machining accuracy.

We have high testing equipment such as third element, the metal crystal imager, altimeter, hardness testers, film thickness instrument to ensure the good working effect of our machines.
