What to Know About Laser Marking on Injection-Molded Parts

Utilizing a laser marking system for your injection-molding operations can bring with it a lot of key benefits for your business. With that in mind, let’s examine some specific marking procedures as well as how to best incorporate laser marking into your injection-molding production so you can reap the full rewards.

Laser Marking System Techniques

Laser marking systems offer several ways to mark essential parts, giving users options for determining what’s best for their products and their customers.

The available techniques include:

  • Laser marking – Using a laser beam, the surface of a selected material is discolored to black or dark gray, producing the chosen text or graphic design. Since oxidation occurs beneath the surface, the material itself remains smooth and intact.
  • Laser engraving – During this process, a selection of your chosen material’s surface area is removed by the system’s laser, creating an exposed cavity. Because of a high level of heat utilized during laser engraving, this selection is vaporized on contact.
  • Laser etching – This process, a subset of laser engraving, is conducted by melting a chosen material and creating a raised mark on the product’s surface.
  • Foaming – For this technique, also referred to as color change, a controlled burn is conducted upon a plastic’s surface. This allows for a fairly smooth surface following marking, and leaves a white, tan or dark mark upon the surface, depending upon the plastic used.

The Benefits of Laser Marking for Injection Molding

Laser marking systems offer a host of benefits for industries who incorporate them into their standard operations. These include:

  • Less wear and tear on tooling equipment due to the noncontact, focused laser beam used in the processes
  • A precise, repeatable process resulting in sharp resolution that can be trusted for essential part-making and design
  • The ability to mark or engrave difficult to access areas, including those found in concave and convex designs
  • An environmentally safe process since the laser utilized creates no toxic byproducts compared to a process like acid etching
  • A faster production speed compared to traditional methods, saving both time and money
  • Hand polishing of materials is often eliminated since the surface material following the laser marking process is much smoother than milled surfaces

Of course, these are only some of the benefits that our systems for laser marking on injection-molded parts can provide. For further insights, be sure to check out our laser marking for plastics and laser marking for electronics pages.

FAQs on Laser Marking on Injection-Molded Parts

What lasers are used with laser marking for injection molding?

To accomplish laser marking on injection-molded parts, you’ll typically use higher-powered MOPA fiber lasers, since they are ideal for plastics. Some plastics, however, may be able to be marked with UV lasers or CO2 lasers. The choice of laser will depend on the materials, application, and desired marking result. Contact our team if you’re trying to determine the best system for your operations and we can assess all the details and make a determination.

What are some quality control measures used for laser marking on injection-molded parts?

Some typical measures taken to ensure accuracy and consistency include material testing and visual inspections. Visual checks are important to ensure the product meets the quality standard desired and doesn’t have any defects such as burn marks.
