Several young entrepreneurs in their twenties started the company in a leased small house. The young men worked hard fully soaked by sweat day and night in the factory with low ceiling and smothering hotness. They tried hard to made the old machinery work with their never give-up sprint, hard-working attitude, and creative mind. The group conquered all kinds of difficulties including low machinery efficiency, high part scrap rate and everlasting money-losing pressure. With creative thinking, they modified and improved the product work flow and added CNC machine tools to improve the efficiency, quality of the product and increase production success rate. Eventually Gskyer got the support and approval needed from the contract company in Germany.
