You can trust Ka Shui,a Hong Kong capital group who has been in die casting industry for more than 30 years.It has two factories,one in Shen Zhen,and the other in Hui Zhou.Personally,I think the Liquidized Metal Die Casting/Forging Dual Control Technology,the Ultra Thin mobile phone casing and Rare Earth Magnesium alloy they have are cutting-edge technologies.It is no wonder that they are enjoying a fast development.
