Ask The ExpertsHow Can I Use RFID for the Injection-Molding of Plastic Parts?
RFID Journal Staff asked 2 years ago

I need to insert an RFID tag inside a part. The temperature cycle is between 20 and 60 seconds, with a maximum temperature of -240 degrees. The tag would go inside a plastic product. The reading distance would be as much as possible, and the tag size would be about 10 millimeters. What would you recommend?

Emanuel,

Würth Elektronik, a German company that manufactures printed circuit boards, has developed a tag that can withstand the injection-molding process, so it can be embedded in crates (see Würth Elektronik Manufactures a Tougher Breed of Tag). William Frick & Co., in the United States, also makes tags that can withstand injection-molding (see William Frick & Co.’s Gen 2 UHF Tags Take the Heat for Manufacturing Apps). Tadbik makes a tag specifically designed to survive injection-molding as well (see RFID IML & BML). I do not believe any of these tags are as small as 10 millimeters, however. A tag that small would have a short read range, which would make tracking items with the tags more challenging.
