core ROOMS

core manufacturing CAPABILITIES

Most castings start with a core. Our experienced core department is capable of producing cores of various size, shape, and complexity. We have the ability to manufacture cores with conventional shell core manufacturing or No Bake molding. Our shell core machine list consists of:

Dependable 100SA, 200SA, 400SA

Redford HS12, HS14, HS16

Shalco U180

No Bake core technology allows us to make cores outside the size restraints of a conventional machine, providing larger flexibility in design and production. No Bake core production is powered by a Tinker Omega PLC controlled mixer with output of 750 lbs/min.

AUTOMATIC MOLDING MACHINES

molding specifications

Our green sand molding operation is powered by Robert Sinto FBO automatic molding machines. Sinto FBO molding machines allow for adjustable height molds and maintain consistency from mold to mold. H&H Castings introduced automatic molding over 25 years ago and are proud to add the newest FBO V to our production line. Total capacity between all three machines exceeds 1500 molds daily.

Automatic molding size specifications:

Sinto FBO II (FBO 2): 16x20” mold size, 5” - 8” mold height from cope, 5” - 8” mold height to drag

Sinto FBO III (FBO 3): 20x24” mold size, 5” - 8” mold height from cope, 5” - 8” mold height to drag

Sinto FBO V (FBO 5): 32x32” mold size, 11” mold height from cope, 14" mold height to drag

IN HOUSE PATTERN SHOP

STATE OF THE ART CNC MACHINES

Powered by Haas VF9 and Haas VM3 CNC machines. The Haas VF9 has a travel range of 84” x 40” x 30”. We have the capability to cut aluminum, cast iron, and urethane tooling board. We are actively quoting new tooling work. Please contact Jake Hammill for a quote.

PATTERN MODIFICATIONS

Many patterns can be modified to run on one of our three Sinto molding machines (FBO II, III, V) allowing older squeeze-box and Roto-lift patterns to be converted to automatic molding adapted for higher production rates. Modifications include match plates, cope and drag, and core boxes. Our pattern shop is well equipped to make transferring existing tooling to H&H. We proudly use SolidWorks in our pattern shop.

MELT SPECIFICATIONS

furnace information

Our melt department is powered by Striko Westofen furnaces hand built in Germany specifically for H&H Castings. Striko Westofen furnaces are well regarded for their stability and operational efficiencies. Our furnaces currently experience less than 1% downtime annually. Capabilities across all furnaces exceed 60,000 lbs. of aluminum per shift. We typically melt the following alloys:  319, 356, 443, 535, 713, and 771 (with capabilities to accommodate other requests).

Our current furnace lineup:

2 Striko Dynarad Continuous Stack Melters

3 Striko Dynarad Crucible Furnaces

2 Striko Dynarad Crucible Ladles

No Bake technology

REVOLUTIONARY PROCESS

We added No Bake technology in 2008 to keep up with growing demand for large scale aluminum castings. Our 180 ton sand system can provide sufficient materials to handles castings over 10+’ in length and over 300 finished pounds.

state of the art reclaimers

Installed in 2018 and built custom by Tinker Omega, our new sand reclamation system is capable of mechanically processing 20 tons of sand per hour and thermally processing 10 tons per hour, keeping our department ahead of the curve for demand.

2 molding lines

No Bake is sufficiently set up to handle any production demand with 2 - 750 lb. Tinker Omega PLC driven mixers. Size restraints in No Bake are essentially limitless.
