Design Guidelines

  • Avoid deep narrow slots — aim for depth:width ratio ≤ 4:1
  • Design threads to standard size; custom threads increase lead time
  • Add at least 0.5mm radius to internal corners where possible
  • Specify only required tolerances — over-tolerancing increases cost
  • Indicate surface finish requirements on drawing; as-machined is default
