Labeling and marking technique for anti-counterfeiting
Hard Nut for Counterfeiters
The subject of counterfeiting and knock-offs is also gaining importance in the plastics industry. To protect genuine products from cheap imitations, the Swiss company Brac AG has developed a tooling-based solution that generates a micro-mirror structure on the surface of the plastic parts. The effect becomes visible upon exposure to light; depending on the viewing angle, the certificate changes to a different color. This optical variability is unique and almost impossible to copy. This process helps to keep product protection costs low, since no additional steps are necessary.
An example of this innovative labeling and marking technique for anti-counterfeiting protection was displayed recently at the Swiss Plastics exhibition in Lucerne, where Ferromatik Milacron Maschinenbau GmbH, Malterdingen, Germany, exhibited a model from its energy-saving all-electric Elektra evolution series. Using a 1+1 mold from Brac AG, an injection molding machine with a clamping force of 500 kN, equipped with a 120 series injection unit, produced a cosmetic jar and cover out of polycarbonate with the security feature in a cycle time of about 20 s.
