It is difficult to demould reasons are as followed: 1. Mould with grooves; 2. The draft is insufficient; 3. the finish of mould is not high Because of the draft caused by lack of fault is very common, in product design, the draft must be in the surface, the draft are usually in the range of 1~2 degrees, in this range as well, special occasion also allows for more than 0.5 degrees.Injec……
