GUIDELINES: Avoid a sharp three-sided corner by using a radius or chamfer. The radius at the bottom of the draw is most critical. The deeper the part the larger the radius or chamfer required. OVERVIEW: The key to good part design in thermoforming is understanding the need for a proper size radius or chamfer.
