Draft Angle

1 、Proper decolleting Angle can avoid product scratching.The demolding slope of smooth surface should be more than 0.5 degree, fine grain (sand) surface is greater than 1 degree, rough grain surface is greater than 1.5 degree.

2 、Proper ejection Angle can avoid product jacking, such as stress mark, top deformation, broken.

3、 In order to ensure that the core of the mould is not out of position during injection molding, uniform product wall thickness can be obtained and the material strength of the opening part of the product can be guaranteed.
