A. If the draft angle of mold texturing is insufficient, we will reduce the texture depth gradually to ensure successful demolding.
B. General Rule:
You require 1° of draft for each 13μ of texture finish depth.
A draft angle of at least 1.5° to 2° is generally recommended. The deeper the texture, the greater the required draft angle. We can calculate the safest pattern depth / release low-draft angle mold texturing solutions for you based on the specific mold’s touch draft angle.
Professional Advice:
Please check whether your tools require mold etching in advance when designing the Draft Angle. You should verify the texturing pattern or Grain No. depth alongside the Draft Angle. Reserving enough Draft Angle is essential to avoiding dragging marks during later injection molding processes.
