: A minimum font size of 20 points is recommended to ensure the plastic resin can flow into every part of the letter.

The mold must:

Designing an injection mold requires balancing part geometry, material behavior, and tool mechanical constraints to ensure high-quality parts and efficient production. 1. Part Geometry Fundamentals injection mold design guide

Draft angles are tapers applied to walls, ribs, posts, and bosses parallel to the mold's opening direction. These angles are essential for smooth part ejection without damaging the part or the mold. A draft angle of at least 0.5° is recommended for most materials, but 1° to 3° is common for trouble-free ejection. Textured surfaces require additional draft—typically 1° of draft for every 0.025 mm of texture depth. : A minimum font size of 20 points

Design within the recommended thickness boundaries of your chosen resin (typically 1.5mm to 4.5mm for most plastics). Draft Angles Part Geometry Fundamentals Draft angles are tapers applied

Sharp corners act as stress concentrators and should be avoided. Use generous radii at all internal and external corners to promote uniform melt flow and improve part strength.
