What was the minimum draft required for plastic part

Question

Accepted Answer

The minimum draft required for a plastic part depends on the material, geometry, and surface finish.

Draft is the angle or taper added to the vertical walls of a plastic part to facilitate its ejection from the mold.
The minimum draft angle is typically 1-2 degrees for thermoplastics and 2-5 degrees for thermosets.
The draft angle should be increased for larger parts, deeper cavities, and higher surface finishes.
The draft angle may also vary depending on the location of the parting line, gate, and ejector pins.
The draft angle should be balanced to avoid sink marks, warpage, and flash.
The draft angle may be reduced by using release agents, textured surfaces, or vacuum-assisted molding.
