数控加工设计指南
特点 | 说明 |
Wall Thickness | Uniform thickness of 1.5 mm to 3 mm is recommended. Avoid excessively thick or thin walls to prevent warping. |
Radii and Corners | Minimum radius of 0.5 mm for internal corners. Avoid sharp corners to reduce stress points and aid in mold release. |
Draft Angles | Draft angle of 1° to 2° is recommended on vertical walls to ensure smooth part ejection. |
暗挖 | Use side actions or lifters to accommodate undercuts. Proper mold design is necessary for parts with undercuts. |
Tolerances | Standard tolerance of ±0.1 mm. For tighter tolerances (±0.01 mm), specialized molds are required. |
Text and Logos | Minimum engraving depth of 0.1 mm and width of 0.5 mm. CNC engraving or laser marking is used for text/logo creation. |
Holes and Features | Minimum hole diameter of 1.5 mm. For holes larger than 5 mm, inserts or core pins are recommended. |
Parting Line and Gate | Gates should be placed to minimize defects, and parting lines should be positioned in non-visible areas. |
Material Selection | Choose appropriate materials such as ABS, polycarbonate, or nylon, depending on the part’s intended use. |
