Our new automatic glass film production line has been put into use

Last month, our company purchased a new automatic engraving machine, which has been installed and deployed recently. The equipment has greatly improved the work efficiency of the process department through computer precision calculation, and also provided major customers with richer, more beautiful and precise lines. The sand pattern shows the texture of the glass, which makes the painted pattern give people the feeling of being breathtaking. The patterns drawn generally have personal "creativeness" and pursuits.
