Adding Logos and Lettering onto Injection Molded Plastic Parts
 
Branding a product by adding an injection molded logo on it seems like the most straightforward move a company could do. However, you will be surprised to know how many people overlook this added bonus when injection molding a product. Adding a logo can highlight and strengthen a brand from the get-go: when customers look at a product on the shelf, when they touch it, and when they interact with it.

 Let’s stop for a second and think about the logos we usually see on a daily basis. They are usually part of labels and stickers, or they are simply silk screened or laser printed onto products. The issue with these methods is that they all need second processing, which means that after these products are injection molded and ejected from the machine, another person or machine has to gather more resources and/or materials to finish the initial manufacturing of the product.

Aside from the extra cost that comes with post-processing, let’s not forget that these methods are all reversible, which means removing it from the product could be quite an easy task for a consumer (or for a competitor for all you know). So why not make your logo part of your product by injection molding it onto it? By doing it conjointly into the injection molding phase, you can save time and resources, plus no one will be able to erase your logo without breaking your product. Good move to keep your product away from duplicates!

Wondering what to consider when including your logo into the mold? Here are some basic rules to ensure DFM (design for manufacturability):

  • Embossed (raised) patterns are usually less costly than debossed (stamped) patterns.
  • In order to protect an embossed pattern from abrasion, a border is recommended (as seen in the picture below). The height of the border should be at least 0.3 mm taller than the protected pattern.

  • If debossed pattern is indispensable, it should have a depth of no less than 0.2 mm.
  • The height of the embossed (raised) pattern should be no less than 0.2 mm.
  • The width of an individual letter/pattern should be no less than 0.3 mm, whereas 0.8 mm would be an ideal width to achieve.
  • The distance between two letters/patterns should be no less than 0.4 mm.
  • A 10° draft angle is necessary for all patterns.

With those rules in mind, you now know what to keep in mind when including logos onto injection molded products. But more importantly, you ensure DFM (design for manufacturability), which is one of the most important, if not the single most important aspect a mechanical engineer should keep in mind when designing products to be injection molded.
