Design Considerations
CNC Machining Design Guidelines
Wall Thickness
Maintain uniform wall thickness (minimum 1.0mm) to prevent stress concentration and ensure dimensional stability.
Corner Radii
Use corner radii of at least 0.5mm to reduce stress and improve material flow during machining.
Draft Angles
Apply draft angles of 1-3° for deep cavities to facilitate tool accessibility and part ejection.
Tolerances
Standard tolerances ±0.1mm; tight tolerances ±0.05mm achievable with premium machining.
Injection Molding Design Guidelines
Gate Design
Optimize gate location and size to ensure proper filling and minimize optical distortions in clear parts.
Cooling System
Design efficient cooling channels to control temperature gradients and minimize internal stress.
Mold Temperature
Maintain mold temperature 60-80°C for optimal optical clarity and dimensional accuracy.
