Along with the capitalization of the LED display application industry, the improvement of production technology and the expansion of production capacity, the competition in the LED display application market has been greatly intensified, which in turn has further lowered the price of mainstream LED display products. Although the revenue of LED manufacturers has maintained growth, the gross profit margin has continued to decline. In order to gain a larger market share, some companies began to adopt vicious competition. In order to obtain a relative price advantage, they gave up the strict control of product quality, which may allow them to make short-term profits, but countless facts prove that, regardless of product quality, It will only be self-defeating.
Strong giant color heads for the wind, in the face of the harsh "price war", in the situation that the profit space is constantly being squeezed, use life to guard the dignity, adhere to the bottom line of the enterprise - check the layers and strictly control the quality. It is based on the persistent pursuit of excellent quality, the quality as the product to the strong guarantee of the market, the powerful giant color and heavy color in the LED screen industry to write their own quality legend.
Raw parts procurement demanding inspection
First of all, the R&D department will test all the raw materials and make corresponding reliability tests. After passing the test, small batches of trial production will be carried out. After trial production in small batches, the batches will be put into trial production in medium batches. There are many specific experimental items, such as: low temperature start, high and low temperature cycle (lighting), sand dust test 8H, salt spray test for 24 hours, vibration test, drop test, etc.
Secondly, the incoming material inspection is carried out. All materials are inspected according to the research and development standards and the main materials are tested. The experimental items include: copper thickness of PCB board, hole copper test, size, aging test for each batch of lamps, etc. , failed to return to the factory.
Abnormal production quality
Strongly developed the industry's most stringent and complete production stop line standards, the entire production process through the SMT workshop environment, printing station, placement station, furnace inspection station, post-furnace inspection or test station, AOI inspection, SMT FQC, mixed lamp, braiding, AI plug-in, assembly group furnace station, assembly group after-slab demolition station, assembly group hand weld station and other 40 stations, each station has a very clear line-stop standard , up to 135.
Once any part of the production is found to have touched the principle of stopping the line, the production stop line is notified according to the relevant regulations. All departments of the company responded positively and immediately executed to check the problem as quickly as possible. At the same time, the powerful giants implement a very strict accountability mechanism, so that rewards and punishments are clear.
Advanced testing equipment escort
The company has invested heavily in the introduction of world-class production equipment, automatic aging lines, automatic tape machines, automatic plug-in machines, automatic glue filling machines, AOI testers, automatic waterproof testing, point-by-point calibration systems and other advanced production and testing equipment. The introduction has comprehensively guaranteed the excellent performance of the company's products. The cutting-edge production equipment and perfect testing system fully guarantee the excellent stability of powerful giant color products.
Because of the tirelessness in product quality control, Powerful Color has won the China Quality Certification Center, China Quality Association, China Administration for Industry and Commerce, ATC Agency, FQLL Agency, Xiamen Municipal People's Government, Xiamen Economic Development Bureau, China Semiconductor Industry. Certification and affirmation of the association, the China Lighting Association and other authorities and authoritative institutions. Ten years of a sword, quality of people's hearts, the future of powerful giant color will live up to expectations, continue to provide our customers with "truthful and sincere service, the best products."
High voltage Vacuum circuit breaker is an indoor power distribution device in the 3~10kV, 50Hz three-phase AC system, which can be used for the protection and control of electrical equipment in industrial and mining enterprises, power plants, and substations. It is especially suitable for places requiring oil-free, less maintenance and frequent operation. The circuit breaker can be configured in the central cabinet, double-layer cabinet, and fixed cabinet to control and protect high-voltage electrical equipment.
Specifications:
1.Vacuum circuit breakers can usually be divided into several voltage levels. Low-voltage type is generally used for explosion-proof electrical use. Like coal mines and so on.
