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 ...

Thin Wall is usually defined by portable electronic parts with a wall thickness of less than 1 mm. For large automotive parts, Thin Wall can be 2mm. Thin-walled molding products require changes in processing technology: higher pressure and speed, shorter cooling time, changes in ejection and gate arrangement. The following are the requirements of thin-wall injection molding to injection machine. H...
