Sungho Electronics Co., Ltd. manufactures film capacitors. Their product line includes metallized polyester film capacitors, metallized polypropylene film capacitors, polypropylene film capacitors, and metallized polypropylene sulphide film capacitors. Sungho Electronics also produces film capacitor manufacturing equipment.
The global film capacitor market is analyzed across various segments including product and type. On the basis of product, the market is categorized into AC and DC. Depending on type, the market is bifurcated into paper film capacitor and plastic film capacitor.
The present capacity of 1.2 billion pcs/annum makes Deki the largest manufacturer of plastic film capacitors in India. Its capacitors are currently exported to Europe, Hong Kong, China, Middle East, Malaysia, Philippines and South Korea. Deki has been growing at an average annualised growth rate of 29 per cent year on year since 1989-90.
The preferred choice of raw materials for capacitor films are polypropylene (PP) and polyethylene terephthalate (PET). PP is independent of frequency and temperature (<105°C) and has a high impulse stability – therefore it can be used in AC and DC applications.
Since 1970, when the first capacitor line was supplied by Brückner, more than 40 lines have been successfully installed. Material optimisation for the sequential as well as the simultaneous stretching process
For large-scale commercial production of microporous separators for Li-ion batteries there are two basic manufacturing processes. The so called wet process (with up to 70% oil) and dry process, both covered and distributed by Coperion.
