Processing method

  • “Engraving is done either by “laser cutting” or “machining”.
  • *You cannot specify the engraving process
  •  *You cannot specify the machining method.”

Possible locations for setting engraving

The engraving instructions can be given on TOP, BOTTOM, FRONT, BACK, LEFT, and RIGHT surfaces (flat surfaces). *Pocket flat surfaces with a depth of 15 mm or less are also available for engraving.

Available number of engraving settings

Several engraving instructions are available for different surfaces.

  •  *Line feed and space input are also supported.
Character size 3~15mm(Can be specified with 1 mm pitch)
17.5~30mm(Can be specified with 2.5 mm pitch)
*Font (font, spacing) and line spacing cannot be specified.

Angle description

  • The angle can be specified in 45 degree steps (0 to 360 degrees).
  •  *The angle is only a rough standard value. Angle accuracy is not guaranteed.

Shipping Days

Normal delivery time (5~ days), long delivery time service (20~ days). No additional delivery time due to engraving settings.

Quality Control

  • Quality precautions for engraving
  • 1. Burrs and burn marks may occur on the engraving area.
  • 2. Some characters may be smashed if a 3 to 5 mm engraving character size is specified.
  • 3. Depending on the material and surface treatment, there is a possibility that the engraving characters may become blurred.
  • 4 The letter size and angle of the engraving are only reference values. DimSensional 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 engraving, there is a possibility of discrepancies in letter spacing and height (ref.: 90 mm or more).
