Detailed Description

Dear Sir/Madam, MANUFACTURED JOONGWON Electric co., ltd. WHAT ARE THE ADVANTAGES OF THE PHOTO ETCHING PROCESS? 1. LOW COST TOOLING Other processes require elaborate tooling, much of which must be done by hand or mechanical process. Tooling in the photo chemical machining operation is done primarily through a series of photo graphic steps, thereby increasing accuracy and reducing tooling costs. Tooling costs van be as little as 1/50 of that required for other processes. 2. SPEED OF DELIVERY When time means money, the photo chemical machining process can save the user thousands of dollars and very significantly reduce the project critical path length by delivering the parts much faster than by any other method. Other processes require up to 6 months delivery time. 3. TOOLING MODIFICATION mum cost. The photo chemical machining process allows the designer to practical experiments at a minimum cost. Furthermore, through changes in the manufacturing process, it may be possible to change hole sizes, two widths, and so forth, without any changes to the tooling. If a design concept us untried, the designer should consult with the fabricator to select the layout which will allow the most flexibility for change at the mini 4. BURRING Some processes give finished pars a burr which amy be detrimental to the functioning of the parts. In the photo chemical machining operation the part configuration is achieved without any surface burr. As we are a large group company, one of the leading manufacturer, innovator, exporter and supplier, we have manufactured Photo Etching process, Auto Section Switch-Indoor type), Auto Section Switch, Cut out Switch, Vacuum Circuit Breaker and Gas Insulated Load Break Switch, SF6Gas Insulated Load Break Switches (configuration), Load Break Switch, Interrupter Switch, Metering Out Fit, PT, GPT and SURGE ABSORBER(S/A), Lightning Arrester(L/A) and Various Fuse etc., and our plant established in 1962 and have more than staves of 100 and we have the more than 60 persons experienced skilled workers in it, more than 6 strong persons in R & D section, more than 7 persons in quality control division and other employees who are in charge of capable overseas sales etc., and our products have been manufactured by most of workers who are experienced and accumulated knowhow more than 20 years and so we have enjoyed the good reputation from home and abroad customers, and our products have been inspected one by one by our quality control department before shipment and all goods have been produced to meet for the international standard(ANSI, IEC) and customer's requirements and we have been tried to keep up with the rapidly changing business environment with advanced high tech machine since established and most products are gained Certification of ANSI, IEC, ISO 9001 & ISO 14001 in 2004. Pls feel free to contact us, if you are interested in our products and any requirements. We look forward to hearing from you soon. Best regards, H.S. Park
