Seal design engineers and end users are continually seeking improved sealing
systems and materials. This paper describes the potential of a new thermoplastic polyurethane (TPU) material to deliver improvements in pressure, speed and temperature capability, which are presented as comparisons to proven industry
standard materials. Performance is demonstrated by virtue of test bench
results of seals made from MDI-, PPDI- and NDI-based materials.
Maximizing packaging machine productivity and performance is imperative to success and is driving OEMs to adopt and invest in the latest technologies that can meet their customers’ challenges. At the forefront of these performance-driven technologies is an integrated control system—or programmable automation controller (PAC)—and latest-generation motion solutions.
This paper introduces the basic fundamentals of proportional-integral-derivative (PID) control theory and the characteristics of each of the PID control loops.
