Have a patent application of new technology and equipment

LG electronics decided to use leather cover for G4 in December last year. So Youngkwang was pressed for time. He put out the leather cover that made manually at that time, and he said, “Our employees made 300 trial products manually and their hands were swollen. But the quality was very bad.” The attached edge of leather cover seemed to have many deficiencies. Mr. Choi with Development team tried to make the edge of cover without fault and invent the technique to avoid detaching. And they developed ‘H-jig’ equipment that add heat and pressure to attach the leather on smartphone cover well and ‘Side cutting’ process that cut to leave 0.75mm.
After trial and error, they found the 0.75mm and made the equipment by themselves.
For ‘H-jig’ and ‘Side cutting’, They applied for patents. They started ‘LG Music phone’ for the first time and produced numerous cellphone cover and case. They finally could develop the leather cover with their skillful molding technique that makes the error range of 0.05mm and reliable partnership with LG electronics for 15 years. Before releasing finalized products, Youngkwang didn’t deal with other company’s works because they thought that should maintain security all every steps.
G4 leather cover has 6 types depending on color and pattern and LG electronics is under consideration about selling by the piece.
