What we do

Complete coil design and rebuilding services

All styles and all manufacturers' designs, worldwide. Send us the make, model and part size range and we will tell you what the coil should be — not just what it was.

Design review and simulation

We evaluate existing designs on any induction equipment with heating process simulations, then propose alternatives that fit your line and your part mix.

Coil rebuilding

Rebuilds of every primary coil type for forging, mass heating, end heating and upsetting, plus heat-treat inductors, cast block and replaceable liner designs.

Upgrades and conversions

Quick-change coil and bus upgrades, replaceable high-temperature roof plates, ceramic-coated rails and Inconel rail conversions that extend service life.

Primary coil types

Forging, mass heating, end heating and upsetting

Open style ID cast solenoidal coil

Solenoidal or RCS “Open Style ID Cast”

The best coil design for forging and mass heating. Only the ID is cast, so the refractory section can be thicker or trowelled.

Angle or molded frame coil

Angle or molded frame

Older but more durable than a solid cast brick design. Reusable pouring forms save repair cost over the fiber housing design.

Fiber housing coil

Fiber housing “Fully Cast”

A European OEM-influenced design. We install corner-tapped brass blocks in place of heli-coil anchoring in the frame boards.

Channel type coil

Channel type “Cast or Plate Lined”

For end heating and upsetting at high volume, where a solenoidal pigeonhole coil cannot index cycle quickly enough.

Oval type coil

Oval type “Fully Cast”

Used when planning around space constraints — bar end heating, plates and axle blanks for forming.

Additional designs serviced

Cast block, replaceable liners, coreless furnaces, transformer windings, modular and reactor coils, MIQ and fabricated heat-treat inductors, rails, cables and interconnection bus.

LiveWebinar

Coil design, refractory and rebuild economics — with our engineers.

An hour on what actually fails on a forging line and what a rebuild should cost. No charge, run quarterly — each date is posted once that quarter's group is full.
