Showcase of Essential Items for Hongwang QC
Quality is the foundation of an enterprise’s reputation and brand.
Hongwang pursues "Zero defect" and "Zero tolerance" on quality management.
Quality inspectors are important "gatekeepers" of product quality.
Today, let’s take stock of the most frequently used quality inspection essentials of Hongwang quality inspectors, and witness Hongwang's fine management that believe in quality first and continuous improvement.

NO.1  METALLURGICAL MICROSCOPE

Under the metallographic microscope, the internal structure of stainless steel can be magnified 100-1500 times. Through microscopic analysis, the microstructure size of the product can be studied. From macro to micro, Hongwang's high standard for product quality has never changed.

NO.2  SPECTROGRAPH

Hongwang spectrographic lab is equipped with the  Inductively Coupled Plasma Emission Spectrometers (ICP-AES), energy-dispersive X-ray fluorescence spectrometers, and direct-reading spectrometers. Such instruments can quickly and accurately determine the qualitative and quantitative determination of the metal elements contained in stainless steel. With the help of these hardcore instruments, the quality inspection of Hongwang products are rigorous and efficient.

NO.3  TENSILE TESTING MACHINE

The tensile testing machine is used to test and analyze the mechanical properties of products such as tension, compression and bending. Only by withstanding the various rigorous tests of a tensile testing machine, products can pass Hongwang’s quality inspection test of and become real “MADE IN HONGWANG” product.

NO.4  SURFACE COATING THICKNESS GAUGE

It is used to measure the anti-fingerprint thickness of colored steel coating. Vacuum coating technology makes the film thinner. Quality inspection instrument makes quality inspection of colored steel more refined. For quality management, Hongwang always keeping in mind the thinking of “working for the best but preparing for the worst”.

NO.5  SPECTROPHOTOMETER

Hongwang strictly controls the quality of colored steel. It’s not just the color difference comparison of the quality inspectors’ eyes, but also rthe strong data.
The colorimeter records not only the color data of sheets,
but also the stable quality standard of Hongwang colored steel.


NO.6  STANDARD COLORED STEEL SHEETS SAMPLES

The QC is a walking color meter measuring instrument.
They can judge whether the product has color difference by comparing the standard colored steel samples. This is the basic skill of a Hongwang’s colored steel QC.


NO.7  SAND PAPER

In the surface quality inspection of cold-rolled stainless steel products, sandpaper is always a good helper to inspect defects. Using the sandpapers of different grits, any defects can be revealed. No matter how small spots or roller prints are, there is nothing to hide under the golden eyes of quality inspectors. It can also clearly define the degree of defects, so as to provide clients with clear and accurate level judgment.

NO.8  DIGITAL MICROMETER & TAPELINE


Digital micrometer is used to measure the thickness of coils. Tapeline is used to measure the width of coils. Quality inspectors are meticulous in product testing and strictly control product quality standards. This is the standard that Hongwang QC must comply with, and it it also the principle that Hongwang has not changed.

NO.9  INTERCOM

For any problems found during quality inspection, the quality inspector needs to communicate with the production line in time, and the intercom becomes an indispensable tool.
Finding the causes of quality problems as soon as possible and preventing them from recurring is an important part of QC’s work.


NO.10  QUALITY TEST SHEET

Major events must be done in detail. It’s important to check carefully and record feedback. The quality inspection form records not only product quality information,
but also the responsibility of the QC.



Hongwang strives for excellence in quality which is inseparable from the rigorous and meticulous quality of the inspectors. Product quality and customer satisfaction are our constant pursuit. Quality inspectors use these quality inspection tools to build a solid foundation for Hongwang.
