Design & Engineering a GM‑E‑2600 Aluminum Tilting Mini‑Stack Melting Furnace for Foundry in Forest City, Ontario
Every furnace project begins with a real production challenge, and this one started in Forest City, Ontario, where a growing aluminum foundry was struggling to keep pace with rising demand. Their melting department relied on outdated equipment that consumed too much natural gas, produced inconsistent melt quality, and slowed down their casting schedule. Melt recovery times were unpredictable, dross formation was excessive, and the furnace simply couldn’t deliver the efficiency or reliability required for modern aluminum casting.
After a detailed evaluation of their melting workflow, alloy requirements, and production targets, it became clear that the foundry needed a more advanced, energy‑efficient, and high‑performance melting solution. The ideal match was the GM‑E‑2600 Aluminum Tilting Mini‑Stack Gas Melting Furnace — a compact, high‑efficiency, natural‑gas‑fired aluminum melting furnace engineered to melt 2600 lbs of aluminum with exceptional fuel efficiency, fast melt rates, and clean molten metal quality.
Phase One of this project focuses on understanding the foundry’s challenges, selecting the right furnace model, and engineering a GM‑E‑2600 system tailored to their production environment in Ontario.

The GM‑E‑2600 Aluminum Tilting Mini‑Stack Melting Furnace
The GM‑E‑2600 Aluminum Tilting Mini‑Stack Melting Furnace represents a new generation of high‑efficiency, natural‑gas‑fired aluminum melting technology designed specifically for modern foundries that demand speed, consistency, and energy savings. Engineered to melt 2600 lbs of aluminum with exceptional thermal efficiency, this compact stack melter combines advanced combustion design with a vertical preheating shaft that dramatically reduces fuel consumption while improving melt quality. Its hydraulic tilting system provides safe, controlled metal transfer, and its optimized refractory structure ensures stable temperatures and minimal dross formation. Built for foundries that need reliable, continuous melting performance — especially in regions like Ontario where energy costs continue to rise — the GM‑E‑2600 delivers clean molten aluminum, fast recovery times, and long‑term durability, making it one of the most efficient and production‑ready aluminum melting furnaces in its class.
Understanding the Foundry’s Melting Challenges in Ontario
The Forest City foundry produces a variety of aluminum castings for regional manufacturers, and their existing furnace had become a major bottleneck. Their older reverb furnace was consuming excessive natural gas, generating high levels of dross, and struggling to maintain stable holding temperatures. These issues were directly impacting casting quality, cycle times, and overall operational costs.
During our on‑site assessment, we analyzed:
Their daily aluminum melt volume
Required melt rate to support peak casting hours
Alloy types and temperature tolerances
Pouring frequency and workflow
Available floor space and ventilation layout
Natural gas supply and pressure
Metal handling and safety requirements
The foundry needed a furnace that could melt aluminum quickly, maintain consistent metal temperature, and significantly reduce natural gas consumption. They also needed a system that minimized oxidation and melt loss — two major cost drivers in aluminum casting.
The GM‑E‑2600 was the perfect solution.
Why the GM‑E‑2600 Tilting Mini‑Stack Furnace Was the Right Choice
The GM‑E‑2600 is a high‑efficiency natural‑gas‑fired aluminum melting furnace designed for foundries that require fast melting, low fuel consumption, and clean molten aluminum. As a tilting mini‑stack furnace, it combines the energy‑saving benefits of stack preheating with the convenience and safety of a hydraulic tilting pour system.
This model is engineered specifically for foundries that need a compact, reliable, and fuel‑efficient melting solution capable of melting 2600 lbs of aluminum with consistent temperature control and minimal melt loss.
Key Advantages for the Forest City Foundry
The GM‑E‑2600 offers several performance‑driven benefits:
High thermal efficiency through stack preheating
Significant natural gas savings compared to older reverb furnaces
Lower dross formation due to optimized combustion and chamber design
Fast melting rates ideal for continuous casting operations
Stable holding temperature for consistent casting quality
Compact footprint suitable for limited foundry floor space
Hydraulic tilting system for safe, controlled metal transfer
Cleaner melt quality with reduced oxidation and turbulence
For a Canadian foundry facing rising energy costs, the GM‑E‑2600 provides a measurable return on investment through fuel savings and improved metal yield.
Engineering the GM‑E‑2600 for the Ontario Foundry
Once the foundry approved the GM‑E‑2600 model, our engineering team began customizing the furnace to match their production environment. Every aluminum melting furnace must be engineered to support the customer’s workflow, alloy requirements, and casting schedule.
Thermal and Combustion Engineering
We designed a high‑efficiency natural‑gas burner system optimized for:
Clean, stable combustion
Low NOx emissions
Fast heat transfer
Precise temperature control
The combustion chamber and burner placement were modeled to ensure even heat distribution and minimal hot spots — essential for maintaining consistent molten aluminum quality.
Stack Preheating System Optimization
The GM‑E‑2600 uses a vertical stack that preheats aluminum charge materials using exhaust heat from the melting chamber. This dramatically improves fuel efficiency and reduces melting time. For the Forest City foundry, we sized the stack to match their charge weight, alloy type, and casting frequency.
Tilting Mechanism Engineering
The hydraulic tilting system was engineered for:
Smooth, controlled pouring
Safe metal transfer
Minimal turbulence to reduce oxide formation
Easy operator access and maintenance
Safety interlocks and redundant controls were integrated to ensure reliable operation.
Refractory and Insulation Design
The refractory lining was selected based on:
Alloy type
Operating temperature
Expected thermal cycling
Desired lifespan in a high‑demand environment
High‑performance insulating materials were used to minimize heat loss and maximize fuel efficiency — a major advantage in Canadian climates.
Control System Engineering
The furnace was equipped with a modern control system featuring:
Digital temperature controllers
Gas flow monitoring
Safety interlocks
Alarm systems
Operator‑friendly interface
This ensures precise temperature control and safe operation throughout the melting cycle.
Fabrication and Assembly
With the design finalized, fabrication began. The furnace shell was constructed from heavy‑duty steel, welded and reinforced to withstand continuous thermal cycling. The refractory lining was installed with precision to ensure proper insulation and chamber geometry.
The burner system, natural‑gas train, tilting mechanism, and control panel were assembled and integrated into the furnace structure. Every component was inspected and verified before moving to the next stage.
Initial Testing and Quality Verification
Before the furnace could move to Phase Two, it underwent a series of tests, including:
Burner ignition and flame stability
Natural‑gas train leak testing
Control system verification
Tilting mechanism testing
Refractory curing procedures
These tests ensure the GM‑E‑2600 is safe, efficient, and ready for pre‑commissioning.
