Shenyang CASE: failed three issues outstanding energy-saving lamp - energy saving lamps, lighting, appliances - household appliances

China Suppliers


< BR> Purchase must first priority security projects. Projects such as electric shock, do not meet the national standard, the product easy to leak, threatening the personal safety of users. Consumers buy used if there is unusual circumstances, should be promptly checked to professionals, to the dealer to reflect, consultation, communication, prevention of unsafe incidents.


<BR> Shenyang Consumer Association recently distributed the city's circulation of 20 species were compared with experimental energy-saving lamps, energy-saving lamps in the 20 kinds of samples, 10 samples were all in compliance with national standards, do not meet national standards in the samples , the more prominent quality problems 3: electric shock, the initial luminous efficiency and power factor.


<BR> Learned, the more test samples, by the Consumers Association staff to the identity of consumers in the supermarket, the professional lighting market random purchase, place of origin involving detoxification foot bath


Guangdong detox aqua foot spa


, Shanghai,


Zhejiang


So a total of 20 companies. Comparison test commissioned by the Consumers Association of Shenyang, Shenyang Institute for Quality Supervision, Inspection and testing, testing includes six projects, including logo, interchangeability, safety requirements for electric shock is a standard item, the initial light effect, light power, power factor performance requirements is a standard item. Determined based on detection of GB16844-1997 "General Self-ballasted fluorescent lighting safety requirements" and GB/T17263-2002 "general self-ballasted fluorescent lighting (energy-saving lamps) product quality inspection program."


<BR> According to the Shenyang City Product Quality Supervision Inspection Institute, the professionals, the initial assessment of energy-saving lamp light effect is the main indicator whether the energy is measured after 100 hours in the burning light of the luminous flux and lamp power ratio (lm / W) . The comparative trial, there are four brands of the item does not meet national standards, namely: nominal Guangdong


Zhongshan


Horizontal bar gold prosper Lighting Factory "Golden Boat Lighting" brand 5W product, nominal subjects for the Zhongshan Guzhen Lighting Factory production of good electronic "Outi light" brand YPZ220/11 products, Zhongshan City, Guangdong Province nominal Siu Lam Lighting industry giant factory town production of "decent lighting" brand 5W product, nominal plant for the production of energy-saving lamps light up the "light up" brand 5W product. The main reason of failure for individual companies to reduce production costs, in the production process does not meet the standard requirements to use the "three color" rare earth phosphor, instead of using cheap common phosphor makes light of light refined not meet national standards effective value.


<BR> In addition, comparison of this test, there are four samples of electric shock project does not meet the national standard, namely: the nominal Huayi Lighting Company Limited for the manufacture of "Huayi Lighting" brand YPZ220 / 5. S. RR products, Zhongshan City, Guangdong Province nominal eras Lighting Appliance Co., Ltd. production of "light off" brand YPZ220V13W products, the nominal Zhongshan ODEER Electric Lighting Co., Ltd. Production of "stingy" brand YPZ220 / 5 Products , nominal power of Guangdong Jin Electric Co., Ltd. Production of "MCO" 7W brand products. Experts point out that there is electric shock quality products, easy to threaten personal safety.


<BR> The comparison test also found that the power factor does not meet the national standards project is also very serious problem. The comparative study, the nominal "Outi Lighting", "MCO", "bright" and "stingy" four brands of subjects the presence of the quality of light samples, problems arise mainly due to light electronic ballast component selection and circuit design unreasonable.


<BR> Selected four energy-saving lamps due attention


<BR> Shenyang Consumer Association reminds consumers: the purchase of energy-saving lamps should pay attention to the following four points:


<BR> One to choose a well-known brands. Well-known brand manufacturers as large, strong sense of quality, production equipment, processes and management tools more advanced, more reliable product quality.


<BR> Second, as far as possible to a large supermarket shopping. Large supermarkets are generally more standardized operating on more stringent product quality checks, distribution, good quality goods. Shenyang CASE test energy-saving lamps of 20 brands, from the big supermarkets have seven brands tested were all in line with national standards 6; from the professional lighting market, energy-saving lamps of 13 brands tested were all in compliance Only four national standards.


<BR> Three security projects should give priority to the time of purchase. Projects such as electric shock, do not meet the national standard, the product easy to leak, threatening the personal safety of users. Consumers buy used if there is unusual circumstances, should be promptly checked to professionals, to the dealer to reflect, consultation, communication, prevention of unsafe incidents.


<BR> 4, when consumers purchase energy-saving lamps, to obtain dealer invoice, credit card, Warranty certificate, in case no quality problems with time and space port.

<BR> Another occasion, he bought a cell phone store cell phone with a sudden failure of a button, so the house phone to the repair shop. However, go halfway, he suddenly found neither with the invoice, nor with the warranty certificate. Then try holding his heart, went into the mobile phone shop.

Appliances to the countryside


Policy process, the major manufacturers are increasing the sales channel investment, faster growth in appliance sales, but sales of home appliance service appliances do not keep up with the development of the situation, farmers there to buy household electrical appliances is difficult to obtain in a timely manner after quality problems effective service. The main problem is that the maintenance service network in rural areas, small, low level of technical services, spare parts supply, a small failure, poor service quality.


<BR> In addition, the Consumers Association of the circumstances of the first half of household appliances complaints that some operators do not stay there three bags of documents to evade the responsibility of the signs of this. In particular, the emergence of "ignoring the mandatory three bags, not the maintenance records do not provide maintenance alone, single-use records in lieu of maintenance" and substituting one concept, avoiding the product should bear the responsibility.


<BR> "However, many home appliance chain enterprises to 'consumer protection law', 'three bags of law', etc. supposed to protect consumer interests and regulations, the advantages of the use of information asymmetry, from word games to play, to induce Consumers are not entirely voluntarily, signing various agreements clearly unequal terms. 1 consumer complaint to the emergence of these 'Overlord terms' business has become the last one amulet, the legitimate consumer causing all sorts of rights violations.

Analysis of China's shoes industry

China Suppliers





As China's pop culture, retro nostalgia, cloth shoes market into a substantial increase in sales year by year, the major shoe piece of cheese in hard swallow. From the brand background, brand shoes currently on the market is broadly divided into three categories: international brands, domestic brands and brand extensions.


under counter ice machine


The purchasing power of international brands by the customer factors, but is still in the collaborative competition "doing cake" stage, not in a hurry overall expansion, but the image of strength on product strength and advantages of equal importance, focusing on cultivating affluent customer loyalty. Occupation of the city's well-known first-class shopping malls; domestic brand refers to the domestic professional shoes manufacturer. They trade, OEM-based, domestic trade for the times, the current domestic trade market to get their attention, so a lot of shoes manufacturer in the domestic market also has a good performance; extension of the brand is from the traditional leather shoes and sports footwear and apparel industry and other branches of industry, well-known brands of shoes out of products. philips crt tv





At present, China's domestic market is not a lot of brand shoes, and many come from behind the mid-term is a pioneer. The big brands on the market are basically in the form of shopping malls to show the image of counter sales, the domestic brand in the second and third line store shop, to join proprietary form of marketing. Cloth shoes are basically the market has just begun. Positioning the product has a high low-end, big brand positioning accurate to the cultural advantages of brands, domestic brands of shoes compared with the price advantage of foreign brands.





"Health" and "comfortable" shoes have been advertised by the two major selling point. Cloth shoes with cotton, velvet, woolen, polyester fabric, denim, leather, canvas and other materials, sole use of rubber at the end with the hemp and other natural plant materials prepared with not only afraid of the water has changed the traditional cloth shoes wet bogey shortcomings, but also retained the soft, comfortable, lightweight features. Also, pay attention to fabric, color, style of a variety of changes, covering cloth shoes of all products. Elegant, simple and unadorned, noble performance vividly to meet the public's aesthetic taste. When art and to study the shoes, creativity and enjoyment of attracting tens of thousands of Chinese consumers flock.





According to statistics, the domestic fashion shoes sold at an annual rate of 68% growth in export volume to 200% of the rate of increase in the next five years, sales of shoes market will reach 500 billion. Cloth shoes for fashion, low consumption power more in line with the general public, its market potential is huge, of course.





With Chinese traditional culture, the left-fu right shoe into the international pop ambu discount business model, which not only focus on fashion and popular culture at the same time the tradition spread in price has also implemented a low-cost strategy, close to the people so that different age groups , different spending power and demand for different purposes, consumers can find the right shoes.





This is also the left-right-an-fu shoes hot sale, subject to the general public the reasons for the pro-gaze. In order to win high-quality, attention to detail perfect. Product design, from Switzerland, Italy, Hong Kong, France and other places designers assume personal command, capturing fashion information and the introduction of global trends. Fabrics with superior materials, excellent production, full of romantic color with a bold, somewhat rebellious design, making the brand has maintained an unparalleled charm. Cloth shoes in China, plays a lead role in the market.

Should actively develop large-scale heavy industry, rolling features

China Suppliers








    With the country-driven domestic demand and industrial development, China's CNC machine tool show to the large-scale, high-speed, low noise, fast response trends. CNC gantry milling, CNC Floor Boring, large five-sided machining centers and a number of sophisticated, large-scale special equipment for the urgent need for large, heavy rolling ancillary features, which indicates that a large, heavy rolling functional components are entering a demand season. gas cooktop glass


canopy range hood


    The face of this rare opportunity for development, many domestic and foreign manufacturers are rolling features introduced corresponding new products, and in April held in Beijing CIMT2009 exhibition, more than half of the rolling feature manufacturers are focused on the introduction of large-scale, re - Scroll feature set products, both of which SK7450 10 meters with an overall precision CNC thread grinder grind of 10 meters precision ball screw, it also imports whirlwind eight-meter CNC milling machine precision milling out the whole 10 meters large ball screw, but also There ball nut rotating main long ball screw-driven, while in large heavy-load linear rolling guide, the national key enterprises have launched a high-rigidity, heavy roller linear guide.





    In large heavy-load rolling feature differences at home and abroad, according to the author personal views mainly in the following areas:





    Basic theoretical research areas: domestic manufacturers engaged in rolling features of basic research personnel was virtually nonexistent. In recent years, with the sense of innovation increases, the domestic several major manufacturers, such as: Hanjiang Machine Tool Co., Ltd., Nanjing, technology, Bot Seiko, Dalian High-King and other enterprises to enhance co-operation with the universities, but only on individual project co-operation, the lack of system is based on theoretical research, while universities may think that scrolling feature is a small industry and lack of funding, are willing to work long been engaged in the study very few high-level personnel. While abroad, such as Germany, Japan and even China's Taiwan's enterprises, since the consortium's support, the capital adequacy, and corporate attention, attracting a large number of high-level researchers engaged in basic theoretical research and new product development.





    The new product development, product performance and reliability: the major domestic rolling plant features a new product, compared with similar foreign products instead of just looks like quite similar. The main reason there was a lack of basic research support; second is the lack of testing equipment for various performance tests. I have been abroad a scrolling feature advanced manufacturing plant visit to see test equipment and production companies a considerable amount of equipment, and domestic exception of a few major manufacturers have a limited number of test equipment, the vast majority of small businesses in this area is blank.





    Processing equipment and testing equipment: domestic features in a large heavy roll manufacturing techniques have made great strides in recent years, several major manufacturers have produced a "column" on behalf of the "beads" of high rigidity, heavy rolling straight Guideway, and bulk import substitution to meet customer needs. In the ball screw manufacturing technology, China has two kinds of sophisticated production process, one uses a large-scale precision CNC grinder manufacturer of precision ball screw thread, the main production equipment Hanjiang Machine Tool SK7450 × 100 CNC thread grinder, Anyang Xin Sheng production SK7450 × 90 CNC thread grinder, as well as the Han River Machine, Shanghai Machine Tool production SK7450 × 50 CNC thread grinder; the other is using hard-spin CNC milling technology, a cutting forming milling, production of large heavy ball screw, The main equipments are imported PW160-type, PW300HP CNC milling machine cyclone, the domestic production of 6 meters Hanjiang Machine Tool CNC milling machine cyclone. The cost of production in foreign countries due to other reasons, multi-use hard rotary milling technology and cold forming technology to process large heavy-load ball screw has been rarely used precision grinding techniques to produce a large ball screw. The cold forming process is difficult due to the product precision is low, cycle, big error, at present at home or blank.





    Testing equipment is currently almost all domestic enterprises, Chinese-made equipment, mainly dynamic precision measuring instrument. Instrument accuracy, reliability, and other indicators have reached international advanced level, to meet the needs of production, and completely replace the imports, but the lack of nuts, rail slider measuring instrument, as well as an integrated performance measurement instrument, the lack of reliability testing, comprehensive performance testing, life testing and other testing equipment.





    Therefore, the prevalence of domestic enterprises lagged behind the accuracy of product performance indicators.





    Direction for the future: National scrolling features the industry after 30 years of accumulation, the development has a certain foundation, one of key enterprises have long been engaged in development, and manufacturing engineering and technical personnel, technical team composed of skilled workers. By continuously introducing, digesting and absorbing foreign advanced technology and manufacturing equipment and testing equipment, I believe that major projects through the implementation of national science and technology, the domestic manufacturers of key enterprises will be equipped with more advanced level that has a large, specialized CNC machine tools and testing equipment, and in basic theoretical research, basic performance test, reliability, research, testing progress. Domestic key enterprises to achieve this goal, all developed their own priorities, including the level of Hanjiang Machine Tool Co., Ltd. for the domestic and foreign advanced levels, put forward five key tasks: rolling feature basic research. optimal design and advanced manufacturing technology research and application. testing technology and comprehensive performance studied. materials, heat treatment and modification of technical studies. precision and performance to maintain the reliability of technical studies. Hope that, through the implementation of major projects in these breakthrough features that make the domestic rolling from the price advantage into brand advantage.
