Company Profile – Yixing Honsing Electronics Co., LtdFounded in June, 2000, Yixing Honsing Electronics Co., Ltd (Hongsing) is located in Yixing City, Jiangsu Province, about an hour’s drive to Wuxi city and 2 hours’ drive to Shanghai through the highways which pass through the city.The company’s current factory occupies an area of over 26,680 square meters; in it are 80 production lines, stock houses for materials and the finished good products, R&D engineering department and the QC department. The production lines own a lot of automatic or semi-automatic production equipments, some of them were imported from Taiwan, there are currently about 600 staffs working in the production lines. These all have enable the company own an output capacity of 0.3 billion units of all kinds of aluminum capacitor products with the voltage ranges from 6.3V to 450V and capacitance ranges from 0.1uF to 10,000uF .The total output of all these capacitors in 2003 had reached 2 billion units, about 80% were exported, among the exported output, Hong Kong accounted for 50%, India accounted 25%, Russian accounted 12.5% and the other countries or regions accounted for rest 12.5%. The total sales revenue of 2003 had reached $8.5 million; mainly gained from the market of audio amplifier, home appliances electronics & electrics and other consumer & industry electronics applications. As an ISO9001:2000 certified enterprise, Honsing has 50 special staffs in charge of quality control to ensure quality in each stage of production, the final products are strictly undergone a 100% examination and testing before entering the stock houses to avoid quality issues which may arise in the customers’ end with their utmost effort. Hongsing recently has built up a 2-floor new production house in its new bought 40,000 square meter land, in the new production house, they will establish 20 new production lines for manufacturing high – end aluminum capacitors, targeting the popularly growing market of mobile communication electronics, such as mobile phone, notebook, PDA, etc. The designed monthly output capacity is 500 million units and the whole project, including hardware facilities and staffs, is expected to be accomplished in Q4 of 2004. According to the general manager of Hosing, Miss Amy Cheung, manufacturing of high end aluminum capacitors will inevitably add about 10% additional costs from raw materials, processing technics, production equipments and experienced staffs, than the middle – end aluminum capacitors, but high – end products can also gain 20% additional profits than the middle – end products, and in addition, the high – end products are more promising in future market and developing high – end products is a good way of avoiding unnecessary critical competition in the current low – end and middle – end market.In order to make better services to their customers, Hongsing established a subsidiary trading company – Yixing Fortune Imp & Exp Co., Ltd early in 2004. The trading company can not only provide the overseas customers with capacitor products from Honsing, but also any other types of electronic component products which the customers want to buy, and further more, as to other types of the electronic component products, such as ICs, discrete semiconductor components, resistors, inductors, switches, etc, provided that the trading company can source them in China, if do, the company will then resell them with bottom prices to these overseas clients. Amy Cheung is optimistic with the new trading company, and thinks it as a revolution of doing export business, and also a win - win project between Honsing and the customers for it can bring much better services to the customers as well as more business opportunities to Hongsing.The whole production process in the current factory can be divided into 7 steps, they are: slitting process, stitching and winding, impregnation, assembling, encapsulation, Aging and reforming, Inspection and packaging.The basic materials for making the capacitors are etched aluminum foil (anode foil and cathode foil), heat-shrinkable PVC pipe, aluminum shell, Spacer paper, electrolyte, the leads, rubber seal, rubber-lined terminal plate, etc, most of these raw materials are sourced from Chinese local vendors and some of the etched aluminum foils are imported.Etched aluminum foils should all be slitted into individual rolls with specified width so as to make capacitors with fixed specifications; this step is processed in the slitting machines working in the slitting work shop. After slitting, the anode foil, cathode foil, spacer paper, along with the steel leads, are put into the special stitching & winding machines, there are totally 104 sets of these machines working in the room, most of which were imported from Taiwan. Through these machines, the slitted anode and cathode foils are stitched with the lead tabs are automatically wound together with the spacer paper to form the “heart” of the aluminum capacitor popularly named as “wound elements”.After stitching and winding, the wound elements are immersed into the electrolyte bath for about 30 to 40 minutes, this procedure is called impregnation, there are 5 sets of impregnation baths which contains one or more poly-hydric alcohols such as ethylene glycol or glycerin as the major solvents and one or more ammonium salts of boric acid or organic acid as solutes to restore damaged oxide film and provide important effects to electric performance and service life of the end product- capacitor.And then, the wound elements, after being dried in special ovens for dehydration, are put into aluminum case and sealed together with rubber seal or terminal plate. This procedure is called encapsulation and achieved with assembly machines; there are 90 sets of assembly machines working in the workroom. After encapsulation, the capacitor bodies are covered with heat shrinkable PVC sleeves with the basic technical information indicated, through sleeving machines in the workroom. In order to restore the damaged oxide layer of the aluminum foil during slitting and stitching process, as well as to debug the initial failure and make the leakage current of capacitor stable, the capacitors should undergo a process of aging ( or called reforming), the process is achieved by arranging capacitors in lots ( one lot contains about thousands of capacitors) in a special electric plate, then they are applied with DC voltage first in a high temperature and then in a normal temperature, some unqualified capacitor may be exploded during this process.After aging, the qualified capacitors are arranged manually in testing machines, there are 95 sets of such machines in the work room, there the major electric performance of the capacitors, such as voltage, capacitance (including up level and down level) , leakage current, loss, etc, are being examined for each capacitors, and the unqualified are automatically put into the recycle bins. Then the capacitors will undergo a through checking for the appearances before packaging, the checking items include: incorrect polarity, wrong mixed items, distortion, electrolyte leakage, and none proper assembly, etc. After the final sampling check by QC, the qualified products are sent to stock and ready for shipment to the clients end. |
