Draft in plastic parts

Draft is provided on parts to ease the process of manufacturing. In manufacturing of automotive plastic parts the most widely used method is injection moulding. Providing draft helps to remove the die easily from the surface of the part.

Benefits of drafting

• Reduces surface contact during die retraction
• It makes the process faster causes less chance of wear in die or defects in components .

Tooling Axis

This is defined as the direction of retraction of die. It is selected in such a manner that most of the feature of the parts are covered in this axis like holes, projections etc.

This tooling axis is choosen becasue it clears 5 feature

• 2 holes
• 2 ribs
• side face
