Machine shops save time with a furnace at their disposal in their own shop. You will no longer send a die out for heat treating, wait for its return, and then send it out again for additional heat treating. Do the work yourself and start a new profit center in your shop.
The door swings open with one-handed operation. The Paragon PMT-18 heat treat furnace is insulated with refractory firebrick. The elements are mounted in dropped, recessed grooves machined into the firebrick. Paragon invented this type of groove in 1952. This groove protects the element for long life and low maintenance. Elements are simple to replace because they’re exposed rather than embedded. You can thread new elements into place following instructions in the manual.
The firing chamber is protected by a steel case painted in high-temperature blue. A built-in stand lifts the firing chamber safely off your worktable, so no extra stand is needed. The door is mounted with a heavy-duty hinge for smooth opening.
A micro-switch shuts off the power to the elements when the door is opened. We use high-temperature wire in the switch box for long life. A heat shield, mounted between the switch box and furnace, helps keep the switch box components cool even during extended operation. To further dissipate heat, the switch box is extra large and generously louvered.

Optional Gas Injection Flow Meter
During heat treating, scale forms on the surface of the steel. One way to eliminate most scaling is to wrap the steel in stainless steel foil. An easier way is to install the gas injection flow meter on your furnace. It is available as either an add-on kit or you can order the furnace with the meter installed. The meter regulates the flow of an inert gas, such as argon, inside the furnace. The gas displaces the oxygen to prevent most scaling. Please remember that results with the flow meter vary depending on the type of inert gas you use and your level of experience.

What is Lost Wax Casting? It is the process of making or carving a shape in wax, then making a mold of the wax shape, and then casting that shape into metal from the mold. The mold is a negative image of the wax. The wax is melted out of the mold through hollow channels called sprues. Lost wax burnout is the process of preparing a casting mold for the melted metal that will be poured into it.
Stainless Steel Wax Trays
If you want to do Lost Wax Casting, you'll need a stainless steel wax tray. Here's the one you'll need for this kiln; a Stainless Steel Wax Tray, 12″ X 12.″ This Stainless Steel Wax Tray system will fit well in your kiln and allow you to do lots of wax burnout.
Place your molds on the removable expanded metal top. The wax will drip from the molds into the tray underneath. Then remove the wax tray before the kiln gets hotter than 300°F / 148°C. Note: Burning wax inside a kiln can damage the firebricks. Check out this 12" x 12" Stainless Steel Wax Tray out to help you in your projects. Here's the link.
