Laser Marking Plastic Capabilities

Plastic and thermoplastic products and components have become integral parts of industrial and commercial applications. Like metal products, plastic components also need to be cut, marked, and engraved. Hai Tech Lasers, Inc. provides the solutions with state-of-the-art laser systems. We offer plastic laser engraving and marking services that can provide huge benefits to your company’s product identification and tracking efforts.

Best Solutions for Laser Marking on Plastic Parts

Plastic and thermoplastic products and components have become integral parts of industrial and commercial applications. Like metal products, plastic components also need to be cut, marked, and engraved. Hai Tech Lasers, Inc. provides the solutions with state-of-the-art laser systems.

What Is Laser Marking?

Laser marking uses a plastic laser engraver to create permanent or semi-permanent marks on various components. It is a non-contact, non-subtractive process, meaning it does not directly contact the object and does not remove plastic from the surface. This reduces the risk of structural integrity loss and mechanical deformation. Alternatively, the method uses a laser to produce discolorations in localized parts of the laser-etched plastic’s surface in distinct patterns and shapes to form markings such as serial numbers and designs, e.g., barcodes.

Techniques for Permanent Laser Marking on Plastics from Hai Tech

At Hai Tech, we utilize two types of laser marking techniques to create precise, aesthetically-appealing markings on a variety of goods and products:

  • HTL QT fiber laser marking: This technique uses a combination of high-tech fiber optics, rare earth elements, and laser diodes to provide precise, permanent markings on virtually any type of material. It preserves the integrity of the items being marked through its no-contact engraving method. HTL QT is ideal for marking or engraving small, custom items like pens, keychains, name tags, small medical implants, and much more.
  • CO2 laser marking: CO2 laser marking provides high-speed, high-quality markings for identification and traceability. This engraving method is most suitable for use on plastics and other non-metal materials. Items commonly marked with this method include rubber stamps, paper products, small signage, trophies, and more.

Benefits of Laser Marking Plastic

Laser marking technology has seen rapid adoption across different industries due to its precision and reliability. Here are some of the benefits pushing the growth of the laser marking plastic industry.

  • Permanent Engraving: The laser marking is permanent and won’t fade over time due to its resistance to chemicals, light, wear, and heat.
  • Font & Marking Sizes: These laser systems can create markings on any size component with font sizes of 2.5 or smaller. Barcodes or lettering can be engraved on large work areas.
  • Easy Integration: Both laser marking systems allow easy integration into larger systems, allowing the ability to work on multiple pieces at once.
  • No-Contact: It is a no-contact process that takes place without removing any material or affecting its physical properties.
  • Uniformity: The engraving process does not produce any tensions, pressures, or fixings, ensuring uniform results every time.
  • Cost-Effective: Laser cutting plastics is a highly cost-effective production process because no additional materials are required and maintenance costs are minimal.

Applications of Laser Marking Plastic

Due to high adoption in diverse sectors, laser marking plastic has many applications, including product traceability, automotive decoration, and secured ID cards. Other applications of laser marking plastic include:

  • Housings made of plastic
  • Electric plugs
  • Electronic components
  • Printed circuit boards (PCB)
  • Automotive parts
  • Keyboards
  • PEEK (Polyetheretherketone) medical devices
  • Identification tags for animals
  • Packaging
  • Films
  • Sensors

Plastic Materials Suitable for Laser Marking

Most plastics and thermoplastics can be easily laser marked, but there are some plastics that do not exhibit color changes when exposed to infrared lasers. However, these plastics can be modified with a suitable additive to allow laser marking capabilities. Below are some of the common plastic materials suitable for laser marking:

  • PolyolefinLaser Metal Marking
  • ABS
  • Phenolic 
  • PVC
  • Epoxy
  • Polyesters
  • Acetal
  • TPEs
  • Nylons
  • Acrylic

Types of Plastic Laser Marking Systems Offered

The right type of laser system can provide immense benefits to product marking and engraving processes. To ensure that we meet the various needs of our customers, we offer the following systems for permanent laser marking on plastics:

  • HTL QT Fiber Laser Marking System: This system has the capability to create markings or engravings on plastic quickly without damaging the material. Fiber laser technology consumes less power as compared to lamp or diode based systems. The operator has the freedom to create different types of texts, logos, and graphics. Fiber lasers create high contrast marks on nearly any type of plastic material.
  • CO2 Laser Marking System: The CO2 Laser Marking systems can create permanent marking on different plastic materials with long-lasting legibility. This system utilizes a different wavelength than the Fiber Laser system, creating a different effect. With the CO2 Laser Marking system, the material is melted and evaporated away, leaving an engraved image with the same color as the base material.
