Tempco Custom Heater Manufacturing

Capabilities IconOur CapabilitIes

Tempco's design and manufacturing capabilities allow us to produce the highest quality Electric Heating Elements, Temperature Sensors and Temperature Control Products.


Perhaps our most important "capability" is our expert and detail-oriented work force. From our sales team and engineers, to our production staff, custom manufacturing cannot be done without our dedicated employees.


Manufacturing: Process and Machinery


CNC FittingsCNC Lathes with Automatic Bar Feeders

Need a custom fitting for your application? No problem! Tempco streamlines the design and manufacturing process by making our own fittings with our 12 CNC Lathes.


Machine ShopCNC Machine Shop

When a tolerance or geometric shape cannot be achieved as cast, we utilize our full service state-of-the-art machine shop. Our CNC machine tools include our lathes, 12 CNC Mills and Boring Mills that can perform all of the precision machining a design may require with repeatable accuracy. We also utilize our machine shop to build and maintain permanent mold tooling for our Casting processes.


video camera icon Plant Tour - Inside Look Video

In this video get a rare sneak peek inside Tempco. Take a look at some of our manufacturing capabilities and processes that produce the quality products that our customers have come to expect. From our humble beginnings 50 years ago in a 1,500 sq.ft facility to our current headquarters today with two manufacturing plants totaling over 170,000 sq.ft., we are very proud of how far we have come.

Roll ReducingRoll Reducing Mill and Exo-Gas Annealing Furnace

Elements are fed into the roll reducing mill to compact the MgO insulating powder. After rolling, the elements are annealed in a conveyor belt furnace.


Water jetWaterjet Cutting Machine

This machine is used across many of our product lines to cut sheet metal for custom panel designs, band heaters, plates for non-pressure flange heaters and other custom heater designs.


video camera icon Cast-In Band Heater Video

Tempco manufactures many Cast-In heaters and thermal components with liquid cooling including band heaters, thermal platens, motor housings, feed pipes, ring heaters, barrel heaters, circulation heaters, platen die heaters and complex geometric thermal components. Our Cast-In thermal components are manufactured with Tempco's tubular heating elements and aluminum, brass or bronze cast materials.

Laser CuttingSheet Metal Fabrication

Along with the waterjet, additional Sheet Metal Fabrication machines Tempco utilizes in our manufacturing processes are:

  • Fiber Laser
  • CNC Turret Presses
  • CNC Press Brakes

Tubular FillingFilling Machines

Our carefully researched manufacturing methods include tubular heating element filling machines that allow us to methodically fill the heating elements with the MgO insulating powder.


video camera icon Air Cooled Shroud Systems Video

We have multiple laser cutters, press brakes, rolling mills and CNC Turret Presses used in the custom manufacturing of our shrouds systems as seen in this video. Used most commonly in the plastics industry, our air-cooled Cool-to-the-Touch and Multiversal shroud systems are ideal for optimized barrel heating and cooling.

Pattern ShopPattern Shop

Our In-House Pattern Shop builds and maintains the wood or plastic patterns required to produce castings with no bake sand molds.


Foundry MeltingFoundry Melting Capabilities

Our electric reverb and induction furnaces are used to minimize gas inclusion into the molten metal, thereby producing a denser, higher quality casting.


video camera icon Custom Fittings CNC Robotic Automation Video

Tempco can custom manufacture virtually any fitting with our Turning Centers with Auto Bar Feeders, CNC Milling Machines and fully automated CNC Turning Center with Robotic Arm loader/unloader. Materials include Aluminum, Brass, Alloy Steel, Stainless Steel and more.

Sand MoldNo-Bake Sand Molds

This process for low-volume Aluminum, Bronze and Brass Cast-Ins is ideal for large, irregular shapes and thermal platens.


Tilt PouringTilt-Pour Gravity Feed

When medium to high volume Aluminum cast-ins are produced, the Tilt-Pour Gravity Feed is used.  It will accommodate simple shape castings and moderately complex shaped castings, producing good dimensional accuracy and surface finish.


video camera icon Custom Fittings CNC & Bar Loader Video

Tempco can custom manufacture virtually any fitting with our 13 Turning Centers with Auto Bar Feeders, 12 vertical CNC Milling Machines and more. Shown here is a CNC Turning Center - 12-Station Twin Turret, Twin Spindle with Live Tooling Capabilities and Y-axis Turning. This machine is combined with an automatic bar feeder.

WeldingIn-House Welding Professionals

We use Manual Welding, Silver Brazing, TIG Welding and Automated TIG Welding in our manufacturing processes.


cULus Certified Panel Shop

We offer general purpose or custom engineered power control panels built in our certified shop, backed by over 45 years of experience in the process heating industry. We can meet all of your requirements from the simplest single zone panel to the most complex thermal loop system. Our Certifications include the following cULus Listings:
