Product quality is the core key for “Made in China” to move towards “Made Smart technology in China“, and it is the key fulcrum for leveraging industrial upgrading and reshaping international competitiveness.
Product quality is of utmost importance to Chicheng Electric. It is not only an intuitive reflection of the company’s technical strength, but also a profound manifestation of the spirit of craftsmanship – with intelligent precision manufacturing technology, the error is controlled within millimeters; with digital full-process control, the quality standard is as solid as a rock; with continuous innovation guided by user needs, every product becomes a vivid footnote of the quality commitment of “Because of focus, let quality surpass price”.
High quality is not just a verbal promise, but a solid support and powerful explanation with detailed and accurate test data. Chicheng Electric needs to go through dozens of rigorous product testing links to produce a qualified product. In the current era of “speed is king”, many processes are advancing against the clock, but there is a process that occupies the “golden 48 hours” in the entire production process of Chicheng Electric, and this process is the “aging” test.
“Aging test” is an important barrier to product quality
Aging test is a durability verification of the gas alarm or sensor module that is continuously powered on to accelerate the process of stress release and performance stabilization of the instrument components. The main purpose of aging test is to ensure that the product can operate reliably in various harsh environments by discovering potential problems and weaknesses.
Through aging test, potential faulty components in the early stage can be eliminated, the rationality of circuit design can be verified, the quality of PCBA welding can be checked, and the reliability and stability of the finished product can be further improved. Only products that have successfully passed the aging test are eligible to enter the next step of the calibration process, which is also the first solid barrier for Chicheng Electric to build a product quality defense line.
2 hours or 24 hours? Chicheng chooses 48 hours!
How long does the aging test take?
While the industry is still debating whether the product aging test takes 2 hours or 24 hours, Chicheng Electric has already engraved this process into the DNA of intelligent manufacturing – because the real quality is never the self-proclaimed “factory qualified”, but the life and death verification under “extreme environment”.
By referring to the standard aging time of different types of sensors and the aging time required for Chicheng product motherboards and chips, Chicheng Electric finally set the product aging time to 48 hours by superposition of time. In the era of Industry 4.0, time is as valuable as gold, and every minute and every second is related to the efficiency and benefits of the enterprise. However, Chicheng Electric insists on implementing a 48-hour aging test on its products, which is not a waste of time, but a profound reflection of the ultimate pursuit of quality.
As a precision instrument, the quality of gas detectors cannot tolerate any carelessness. Products that are hastily delivered without strict testing may seem to be intact on the surface, but in fact they hide various unpredictable defects. It is particularly noteworthy that most of these defects are concentrated in the early stages of product use. Once a problem occurs at this stage, it will not only cause great trouble to the user, but also pose a threat to the safety of use. Therefore, it is very important to conduct a comprehensive and detailed inspection of the gas detector.
It is based on this insight that Chicheng Electric resolutely implemented a 48-hour aging test to allow the product to stand the test of time under simulated extreme working conditions, and to expose and solve the hidden dangers that may affect the long-term and stable operation of the product in advance. In Chicheng’s view, only products that can stand the test of time can win long-term recognition in the market and stand firm in the fierce market competition.
Aging test, from manufacturing to “quality manufacturing”
In the aging workshop, when the product is connected to the power supply, each instrument must undergo an extreme test far beyond normal use. The power supply releases analog current and voltage to the product’s motherboard, chip, and sensor. These currents quickly reach the “assessment” battlefield and begin to “stimulate” the various components of the product without stopping. This is not only a comprehensive review of product performance and quality, but also an early adaptation to the future working environment to ensure that they can work stably under any harsh conditions.
Automated aging monitoring system, improved efficiency and more reliable quality
The tide of the times is surging forward, and technological innovation is unstoppable. With the continuous precipitation and strengthening of Chicheng Electric’s R&D strength, the launch of the automated aging monitoring system has saved the company a lot of manpower costs.
In the past, Chicheng Electric’s aging test used a relatively primitive method, and every 6 hours, a worker on duty would personally check the aging situation and make written records. After the automated aging monitoring system is launched, the system will always monitor the aging data of the product and report the problem data in a timely manner. Through big data analysis, Chicheng continues to optimize product design and improve manufacturing processes. Any potential problems are discovered and corrected in a timely manner to ensure that every instrument shipped can meet nearly perfect quality standards, allowing gas detectors to continue to reach new levels in durability and reliability.
However, in the aging workshop, there are still workers who will come forward from time to time to check the aging of the instrument to prevent unexpected failures in the monitoring system. Chicheng Electric’s adherence to the spirit of craftsmanship is subtly affecting every employee. With this persistence and adherence to quality, Chicheng Electric has gradually established its own quality kingdom.
In order to better meet market demand and keep up with the pace of supply, Chicheng Electric expanded the aging site and introduced advanced aging detection equipment, which can handle the aging tasks of more than 3,200 instruments at most. It is like a powerful quality fortress, providing solid guarantee for every instrument shipped out of the factory.
In the wave of intelligent manufacturing, Chicheng Electric has always adhered to the product positioning of “quality surpasses price because of focus”, ensuring that every gas detector is a passer of the 48-hour “baking test”, a conqueror of extreme environments, and a guardian of gas environment safety.
