Green Sand Casting: Hunter high-speed molding is used
for producing bread-box sized, green sand castings. Pin lift
cope and drag machines are used for medium and large sized
castings. Cores for both Hunter and pin lift are produced
using state-of-the-art automated SO2 machines. Traditional
bench molding is used to produce samples and short run parts.
No-Bake Casting: Commonly refered to as dry sand or
chemically bonded sand process is used to produce medium
to very large castings. The best part-to-part dimensional
accuracy can be delivered on large complex castings. Large
to medium size cores are also manufactured using this process.
Permanent Mold Casting: Our permanent molds are
handled using Hall and Stahl tilt pour machines. This technique
reduces metal tumbling during the pour resulting in superior
metal quality. Problems with internal gas, dross, and dirt
are virtually eliminated. This process is best suited for
high production commercial castings. Aircraft quality castings
are also being produced when higher properties are required.
Lost Foam Casting: Delivers the least costly of
our complex parts. Casting to size on flat surfaces, slotted
holes and cast bores can eliminate machining. Cores are
eliminated on back draft details, undercut part lines,
deep holes and other features, which simplify molding and
cleaning processes. Excellent dimensional accuracy can
be maintained with this process.
