Our biggest seller - 18" Oven For Heat Treating Knives.

The LB 18 is the most popular LB Series heat treat oven with Knife makers and Bladesmiths. Capable of all heat treating processes up to 2200°F (1204°C). It's 457mm deep design and power to safely ramp your product to 1000’C in approximately 1 hour makes it a perfect fit for both private and low volume heat treaters, especially knife makers.


The chamber is a very useable 254mm wide and has an easy to access 165mm height. (Compare this capacity and access with other manufacturers designs and think of your current and future needs)


Also having no heating elements in the back wall and the comfortably width reduces the risk of overheating tips and uneven heat distribution between multitple racked items.


The chamber is constructed with firebricks wrapped in a stainless steel jacket. Compared to fibre type insulation, this construction maintains a more consistent temperature when accessing internally during heat treatment cycles. Also unlike fibre based materials it does not go brittle over time therefore eliminating the risk of tearing, drooping or producing fibre filament dust.

CE Marked ovens feature a "Swing View" Control Panel, a Power Interrupt Swich to cut power when the door is opened, a swing-out door with an external Door Guard and cool-touch handle for comfortable use.

Control Relay

There are 2 Control Relay options available - Mechanical and Solid State.

Solid State

Known as the "Quiet Drive Solid State Relay", the Solid State reacts more quickly than mechanical relays which translates to even more precise temperature control. Solid state does so without the constant "clicking" and eventual failure of a mechanical relay. We fully expect our solid state relay to last the life of
