07 Jun Prevent Product Counterfeiting and Tampering of Plastic Parts

To prevent tampering with your plastic components and reduce the risk of counterfeiting, use permanent marking solutions. Marking plastic for traceability can:

• Protect intellectual property for components in electronic devices.
• Promote patient safety in medical devices.
• Ensure product cleanliness and authenticity in personal care products.
• Verify the integrity of product packaging for food and beverages or pharmaceuticals.
• Authenticate automotive parts and their integrity.
• Prevent counterfeiting of identification cards.
• Allow for quality control of industrial components used in machinery and other equipment.

Why Permanent Marks Are Important

Most manufacturers have plastic parts that need some type of identifying mark. Marking on plastic materials can add a unique challenge to the process of tracking and identification. Oftentimes, the manufacturer uses sticky paper labels on their plastic parts but finds that this method is not the best option. A label can tear off, can become dirty and unreadable, the surface may not allow the label to stick, or the paper can get wet and simply rub off.

Permanent marking is the most desired option for all manufacturers that plan to track or record information about a part. Marks can prevent tampering and counterfeiting with:

• Deterrence features: Clearly visible and permanent markings can deter tampering when individuals see the unique identifier.
• Traceable identifiers: Identifiers like barcodes or serial numbers allow for traceability throughout a product’s lifecycle to help monitor for tampering.
• Authentication identifiers: Permanent markings can help consumers confirm a product’s authenticity to know they’re avoiding a counterfeit.

To achieve permanent marking, the marking must be done directly onto the plastic material. This can be accomplished with several different methods.

How to Permanently Mark Plastic Parts With Scribe Markers

For true permanent making, the manufacturer can scribe the mark into the plastic. This is a mechanical process that drives a scribing pin across the surface and engraves the mark into the plastic without puncturing it. The amount of pressure the pin applies will determine the depth of the mark in the material. Even very light scratched characters can be achieved with this method.

The scribe marker can work on most plastic applications including ABS, Delrin, polypropylene, PVC, HDPE and many other types of plastic materials. Easily integrate any variety of markers into your manual or automated operations. Produce accurate and clean markings and crisp text that is easy to read.

Permanent Marking on Plastic With Laser Marking Systems

Another true permanent marking method would be to use a laser to mark the plastics. A laser can give you a melted mark or a high-quality surface mark with very high contrast. The laser can be absorbed into the plastics to create contrast without burning or foaming the material. This creates a very smooth mark that is critical for some applications, especially for medical implants. The laser can also produce customer logos, codes, boxes and microprinting.

Because plastics have a wide range of colors, density, and material design, specific lasers work better with different materials. Your options include:

• The Green Laser (532 nm) has a very high absorption ratio that can produce beautiful marks on PVC, ABS and polystyrene.
• An ultraviolet laser (375 nm) is perfect for marking on HDPE material. HDPE material is the standard material used in pill bottles, shampoo, health and beauty containers and many of your pharmacy containers.
• Fiber and Vanadate lasers (1064 nm) work well on many high-density plastics such as delrin, ABS or many of your automotive material plastics. Even a very detailed diagram or photo can be printed on the plastic material for a permanent option.

Laser marking is an environmentally friendly option that reduces your production waste. Tools like fiber lasers are no-contact, making it perfect for industries like the medical sector or food and beverage producers, where avoiding contamination is key.
