Thermal Corporation distributor in South Carolina
Custom industrial heaters and temperature sensors, made in the USA. MAHC supplies Thermal Corporation products to manufacturers, OEMs and maintenance teams across South Carolina and the surrounding region.
A failed band heater stops a machine
Thermal Corporation — based in Madison, Alabama — has manufactured industrial heaters and sensors for decades, with particular strength in custom heaters, plastics processing equipment and fast-turnaround replacement work.
What to Send for a Replacement
Heater type, inside or outside diameter, length or width, voltage, wattage, lead style, lead length, terminals, holes or notches, the existing part number and photos. Don't have every specification? Send what you have.
Help me replace a heaterIf It's a Band Heater
Include the barrel or nozzle diameter. Because mica bands are highly customizable, that dimension plus the width and lead arrangement usually defines the part.
Worked barrel exampleIf It's a Cartridge Heater
Include the heater diameter and insertion length, along with voltage, wattage and lead configuration. A clear photo plus dimensions is the best place to start.
Built for Plastics & Molding
Injection molding machines, extrusion equipment, processing barrels, nozzles, dies, molds, platens, packaging equipment and OEM machinery — Thermal Corporation's history is tied to this industry.
Plastics & extrusion solutionsHeaters built around the machine
Standard configurations when they fit, custom constructions when they don't.
Mica Band Heaters
Used around barrels, nozzles, pipes and other cylindrical surfaces, configurable by diameter and width, voltage and wattage, lead style, terminal location, clamping, holes and notches, sheath and mounting.

Ceramic bands for higher-temperature barrel duty on molding and extrusion equipment, and rectangular bands for dies, molds and other applications where a cylindrical heater won't fit.
Discuss a custom band heaterCartridge Heaters
High-temperature swaged cartridge heaters for dies, molds, platens and other applications where heat has to travel through a drilled hole or metal mass — built around your diameter, length, voltage, wattage, lead configuration and termination.

Mica strip heaters for flat surfaces — dies, platens, hoppers, tanks, containers and equipment surfaces — with post terminals, lead wires, flexible protection, holes, notches and bends as options.

If you have a drawing, send it. If you don't, a dimensioned sketch and clear photos are often enough to start. We'll help define the heater so it can be quoted properly.
- Special dimensions and non-standard voltage or wattage
- Holes, notches and cutouts
- Special lead locations and terminal arrangements
- Special sheath materials
- Mounting features and application-specific configurations
- Thermocouples and RTDs to match — calibration, probe size, sheath, mounting and termination
Start with the heater in your hand
You don't need the original manufacturer's part number. Four steps and a phone camera get us there.
Take a Few Photos
The complete heater, the electrical connection, the leads or terminals and any label or markings.
Measure It
Diameter, length, width, thickness and any important holes, notches or mounting dimensions.
Read the Electrical Information
Voltage and wattage markings, even partial ones. Then tell us where it goes — barrel, nozzle, die, mold or platen.
Send It to MAHC
We'll use it to work toward a Thermal Corporation replacement, or cross-reference it to another line we carry if that's the faster route.
Cross-reference serviceThermal Corporation heater FAQ
Mica handles most barrel and nozzle work and can be built with the holes, notches and lead locations needed to fit around existing machine features. Ceramic is the choice for higher barrel temperatures on molding and extrusion equipment. Send MAHC the barrel dimensions, operating temperature, voltage and wattage and we'll point you at the right construction.
Yes. A dimensioned sketch, photographs of the existing heater and its terminations, and the electrical ratings are usually enough to define a custom Thermal Corporation part. We'll confirm the remaining details with you before it goes out for manufacture.
They do — thermocouples and RTDs configurable by calibration, probe diameter and length, sheath material, lead protection, mounting and termination. That means the element and the sensor measuring it can come from one build, matched to the same application.
