What is the minimum draft angle required for a product with graining or texture, such as car interior plastic parts?

Question

Accepted Answer

The minimum draft angle for products with graining/texture, like car interior plastic parts, is typically 1-3 degrees.

Draft angle is the angle between the vertical direction and the sidewall of a molded part.
Graining or texture on plastic parts can make it difficult to release the part from the mold.
A minimum draft angle of 1-3 degrees helps ensure easy ejection of the part from the mold.
Insufficient draft angle can result in sticking, deformation, or damage to the part during ejection.
Examples of car interior plastic parts with graining/texture include dashboard panels, door trims, and center consoles.
