Pressurex® flexible Mylar-based sensor film from Sensor Products (Madison, NJ) captures and permanently records pressure distribution and magnitude between mating or contacting surfaces in the injection-molding of medical devices. After being clamped up and placed around the parting line of a mold, the sensor film indicates whether the pressure is evenly distributed. It reveals pressure from 2 – 43,000 PSI and is available in eight different pressure ranges.
