DFM, tolerances and quality

What inspection equipment do you use?

Answer

Being precise about the boundary is more useful to a buyer than a longer equipment list: No coordinate measuring machine (CMM). For complex free-form geometry we use the 3D scanner, and for parts that need a formal CMM report we arrange measurement with a partner laboratory and say so before quoting. No in-house metallurgical laboratory. full material certification comes from the mill, and heat treatment is carried out by qualified partner plants.

What an engineer still needs from you

  • material and material condition (grade, temper)
  • material thickness, plus the key diameter, height and wall thickness
  • tolerances, burr direction and the visual acceptance standard
  • annual volume - it decides whether tooling is single-hit, progressive or transfer
  • surface finish, and any secondary machining, annealing or plating
Next step. Send the drawing for a manufacturability review, or send the part data for a process and cost route.
