Draft Angle in Enclosure prototype

In generally, any one side of the molded product, are required to have a certain amount of slope, so that the product from the mold is smoothly released. Most of drafts is 0.5 degrees to 1 degree. Select the draft angle specific attention to the following points:

• Plastic surface is glossy, high dimensional accuracy, shrinkage, and should use a smaller stripping slope, such as 0.5 °

• Higher, the larger of the size, per actual calculating to take a smaller draft angle

• If shrinkage of resin is large, it should be used in a larger slope value

• Plastic wall thickness is thick, make the mold shrinkage increases, stripping slope should use a larger value

• Transparency draft angle should be increased in order to avoid scratches. Under normal circumstances, PS material slope should not be less than 2.5 ° ~ 3 °, ABS and PC material slope should not be less than 1.5 ° ~ 2 °

• With texture, sand and other exterior treatment should take draft is 2 ° ~ 5 ° depending on the circumstances, depending on the specific striae depth may be. The deeper striae, slope should be greater

• When structure designed to be shut off each other, the shut off side slope is generally 1 °
