Nobody thinks of Spartanics as a household name, yet it is likely that every household in the Western world, and many in developing nations as well, have products that were made with the help of Spartanics equipment. Nearly every credit card in the world, for example, has been counted one or more times by one of Spartanics automated Card Counters. Look inside many wallets of U.S. citizens and you will find a drivers license that was made with the help of Spartanics high precision Die Cutting Systems for decorated plastic material and/or Spartanics automated Card Inspection Systems. Look inside the wallets of others and you might find voter ID cards, telephone cards, loyalty/gift cards, and a majority of insurance cards, which were similarly created and counted with Spartanics technology. Look elsewhere and find product packaging, appliance nameplates, electroluminescent watch faces and mobile phone panels, playing cards, folding maps, parking lot hangtags, hotel “DO NOT DISTURB” signs, refrigerator magnets, and more—all made with the aid of Spartanics equipment. Within the past five years, we introduced technology for Laser Die Cutting and roll-to-roll Screen Printing Lines allowing us to further broaden our reach in the printing and converting markets. New technology for Laser Die Cutting, paired with digital printing systems or converting lines, gives Spartanics further reach into many label markets including pharmaceutical and consumer product labels. Our screen printing technology is serving RFID label markets, portable electronics and photonics or solar film markets While consumers remain unaware of the Spartanics name, the world’s leading manufacturers of products made from polyesters, paper, polypropylene, polycarbonate, aluminum and other materials are likely to think of their Spartanics equipment as a secret trade advantage. From circuit boards to automobile trim, to insurance cards to financial and smart cards, to labels to photonics and beyond, Spartanics high precision technology is often the unseen hand in speeding production processes across the globe. Founded in 1963, Spartanics headquarters are located in suburban Chicago near O’Hare International Airport. Spartanics worldwide service organization also maintains offices and spare parts in Germany.
