An engraved mark can identify a rubber part with a number, direction or logo. Visibility depends on the rubber and surface. A mark that works on one grade may look different on another.
What should the marking communicate?
Use a short code, clear symbol or simple text. An assembly arrow has a different purpose from a decorative logo. Select details for the distance and conditions in which they will be read.
Specify cutting and engraving separately
For a new part, give the cutting contour one line colour and the mark another. Convert text to outlines, then select the operations offered for the rubber product.
Read the basics in cutting and engraving. An existing customer-supplied product needs assessment through product engraving.
Use an accessible surface
A mark can become difficult to see on a heavily curved or compressed area. Put identification where it remains accessible during use. Keep markings away from critical sealing edges if they could affect function.
Inspect the result in use
Make a trial in the selected rubber. Read it after fitting or deforming the part as it will be used. Include dirt, lighting and wear where relevant.
Compare products in the rubber collection. Readability and wear resistance are different properties: a visible new engraving does not establish how long it stays legible.
