Quality Control

  • Quality precautions for etching
  • 1. Burrs and burn marks may occur on the etching area.
  • 2. Some characters may be blurred if a 3 to 5 mm etching character size is specified.
  • 3. Depending on the material and surface treatment, there is a possibility that the etching characters may become blurred.
  • 4 The letter size and angle of the etching are only reference values. Dimensional accuracy is not guaranteed.
  • 5. Depending on the content of the characters, there may be cases where the size differs from the specified size
  • 6. Depending on the total length of the etching, there is a possibility of discrepancies in letter spacing and height (ref.: 90 mm or more).
