Crucible Furnaces

A workhorse in the industry, crucible furnaces offer a high degree of flexibility and overall efficiency. Whether used as a melting furnace, holding furnace or both, crucibles are a perfect solution for cost effectiveness and ease of implementation.

Available in static, tilting, or mobile variations and capable of daily cycling from melt down to fully empty bath, crucible furnaces offer unique flexibility for job shops producing several different alloys in relatively smaller batches.

Holding Bale-Out Furnaces

SINC Thermal specializes in electric immersion heated holding furnaces for compact installation at the point of use. Through direct contact with the molten aluminum, electric immersion heaters offer the highest heat transfer, and energy efficiency with minimal dross formation. These features combine consistent and reliable operation while optimizing the service life of the refractory lining.

Perfect for die cast or traditional foundry applications with an energy efficient lining that minimizes risk of metal infiltration to the furnace shell. SINC’s compact design allows easy access for cleaning, quiet operation and low heat loss for boosting energy efficiency while also improving the working environment for your operators.

SINC’s standard holding furnaces feature multiple options for loading and bale out with custom configurations available to suit any application. Each SINC holding furnace is readily compatible with launder systems, pump systems, and automatic or manual ladle bale out systems. As standard options, SINC’s holding furnaces readily accept filter plates, laser level probes, and multiple temperature monitoring points.

SINC Thermal also provides a full line of gas fired holding furnaces with many of the standard features and technologies for ultimate flexibility to suit your application.

Central Bulk Melting

Central bulk melting represents the greatest strength of SINC’s Partnership with Gillespie & Powers, a globally known leader in dry hearth reverberatory melting and holding furnaces. SINC Thermal has unique, robust solutions and access to patented technologies not typically offered at the foundry level.

Reverb Furnaces

SINC's reverb furnaces have a simpler design and lower maintenance requirements, creating a perfect solution for local central melting in foundry applications. Compatible with all bale out configurations including tap out, dip ladle, tilting, pump and launder systems for safe and efficient transfer of metal to point of use. Reverbs offer high flexibility with operating arrangements and incoming scrap, including low density scrap melting, chip recycling and metal circulation.
Standard Holding Capacities
3,000-30,000 lbs.
Configurations Available
Tap-out, Tilting, Bale-out & Pump-out
Special Applications
Chip Melting, Mechanical and Electro Vortex

Shaft Melting Furnaces

Shaft Melting furnaces offer the best on-demand melting efficiency and lowest molten metal inventory costs. SINC Thermal brings a fresh perspective by combining industry standard designs and the engineering expertise of Gillespie & Powers for a wide range of aluminum melting applications.

Automatic loading, natural and efficient energy recuperation through the charge shaft and the versatility to integrate with launders, pump systems, etc. make the SINC Shaftmelter an investment in the future. SINC shaft melting furnaces are an excellent option with standard melting rates of 1,000-8,000 lbs./hr,  standard holding capacities of 2,500-20,000 lbs. and are available in tap-out, bale-out and pump-out configuration.

Phoenix Thermal Sand Reclamation

SINC Thermal's patented, thermal sand reclamation technology delivers from its unique design that reduces energy costs, improves sand quality and lowers the maintenance burden of your foundry. A rotary design, SINC Phoenix is unique in that it mechanically fluidizes the sand for improved combustion, reduced wear and 50% less energy inputs in comparison to the competition. With an integrated cooler classifier, the SINC Phoenix delivers ultimate fines reduction for improved sand quality.

Thermally reclaimed sand results in the most complete removal of sand binders for minimizing LOI’s and improving casting quality. In addition to driving casting quality, thermally processed sand becomes more stable and lowers sand degradation typical of mechanical reclamation systems.

The SINC Phoenix system also includes simple metering equipment, process diagnostics, and a unique pneumatic sand transporter for delivery post processing.
