Engine Head Preheating and Welding Furnaces
We design and manufacture specialized chamber furnaces for preheating and controlled stress relief of cylinder heads and engine blocks (aluminum and cast iron) before and after TIG or gas welding processes. They prevent thermal shocks and eliminate the risk of recurring microcracks.

Solid Construction and Casting Safety
Proprietary solutions created for welder convenience and the durability of reconditioned parts
Protection Against Cracking
Uniform preheating of the body to the optimal temperature relieves stress and prevents shrinkage cracks during welding.
Hinged Working Cover
The top-opening design allows efficient surfacing/welding of defects without having to completely remove the hot casting from the chamber.
Controlled Cooling Ramp
The Novus digital PID controller allows programming a slow cooling cycle after welding, eliminating hard structures in the weld seam.
Basic Dimensions of Cylinder Head Furnaces
| Chamber dimensions [W x H x D mm] | Loading Method / Access | Max Temp. [°C] | Power [kW] |
|---|---|---|---|
| 350 x 350 x 850 | Hinged lid / Top-loading | 650°C / 900°C (optional) | 6.0 kW |
* Dust-free insulation: High-quality ceramic fiber blanket and hardened boards eliminating dust in the welding area.
* Reinforced hearth: Durable fireclay floor or steel grate facilitating stable and safe positioning of heavy castings.
Where Are Cylinder Head Furnaces Used?
