Our country plastic mould market in order to mould plastics mould to be demand most heavy, develop focal point the engineering plastics mould among them.  Inject an important method that shaping is plastic shaping, it is mainly suitable for the shaping of the hot plasticity plastics, the precision of all right shaping with complicated form moulds one. This subject is to regard the front part of mobile telephone as the design model, regard it as the basis to inject the relevant knowledge of the mould, explain the plastics inject the design process of the mould. Originally design and mould and design the note that the front part of mobile telephone carries on, utilize UG software to carry on e
