UltraFlex induction heating a steel cylinder prior to epoxy curing

In a recent test application set up for demonstration purposes, UltraFlex proved the energy- and cost- efficiency of induction heating for a steel cylinder, prior to using it for epoxy curing. The demo setup had been done per request of a plastics manufacturer looking to switch from resistance heating to induction heating, to reduce heating cycle times and achieve increased repeatability.

In a recent test application set up for demonstration purposes, UltraFlex proved the energy- and cost- efficiency of induction heating for a steel cylinder, prior to using it for epoxy curing. The demo setup had been done per request of a plastics manufacturer looking to switch from resistance heating to induction heating, to reduce heating cycle times and achieve increased repeatability.


The goal of the test application was to evenly heat a steel cylinder to 250°F (121°C) prior to using it for epoxy curing. Maintaining the temperature below 350°F had been critical for this process, to avoid burning of the epoxy. Hence, using an induction heating solution with a digital temperature control had been a must for this customer scenario and a key reason why the manufacturer turned to UltraFlex.

Considering the size, shape and material of the workpiece, UltraFlex engineers considered the UltraFlex UltraHeat SM induction heater as most appropriate for this application case. UltraHeat SM is a 5 kW induction heating system that operates with either a water-cooled or air-cooled remote heat station. It is easy to tune to a wide range of loads and coils and has multiple user programs and programmable parameters.

Using UltraHeat SM, the induction heating for the sample part had been successfully completed. The target temperature had been successfully reached, in a fraction of the usual heating time needed and a resin compound could then get injected into the part for curing. Energy savings in this process had been considerable, since induction heating can turn up to 90% of the energy into heat into the part. Thanks to the elimination of open flame, this had been a completely green process - eliminating smoke, waste heat, and noxious emissions. Finally, the process had been fully safe for the operator and not dependent on the operator skill. When implemented on the production line, it would ensure repeatability and consistent results every time.

T.J. Davies' Retention Knobs

Our retention knobs are manufactured above international standards or to machine builder specifications. Retention knobs are manufactured utilizing AMS-6274/AISI-8620 alloy steel drawn in the United States. Threads are single-pointed on our lathes while manufacturing all other retention knob features to ensure high concentricity. Our process ensures that our threads are balanced (lead in/lead out at 180 degrees.) Each retention knob is carburized (hardened) to 58-62HRC, and case depth is .020-.030. Core hardness 40HRC. Each retention knob is coated utilizing a hot black oxide coating to military specifications. Our retention knobs are 100% covered in black oxide to prevent rust. All retention knob surfaces (not just mating surfaces) have a precision finish of 32 RMA micro or better: ISO grade 6N. Each retention knob is magnetic particle tested and tested at 2.5 times the pulling force of the drawbar. Certifications are maintained for each step in the manufacturing process for traceability.
