Industry leading Sand Casting
Bernier Cast Metals, Inc. has been producing sand castings since 1945, and over the past 70 years we have continued to perfect our talent. As a fourth-generation family owned and operated business, we have used our knowledge to pass down the best practices and techniques as well as adopting the latest advancements in casting processes. Specializing in green sand molding, air-set molding, and lost foam casting, we have succeeded in expanding our facilities, technology, equipment and services.
Air-Set (No Bake)
Dry sand is combined with a liquid resin and hardener. The resulting mixture is then compacted around a pattern and left to set. When the mold halves are pulled apart, the pattern removed, and the mold is closed, molten metal is poured into the mold cavity. The air-set (no bake) process can handle larger and more complex parts than with the green sand molding process.
Green Sand Castings
Granular refractory mineral is coated with mostly bentonite clay and water, and then compacted (molded) around a pattern. The molten metal is then poured into the mold and allowed to cool. Once the mold has been shaken out, the resulting casting is a strong, durable product. The green sand molding process is used to make simple-shaped parts. The benefits are in lower-cost tooling, faster turnaround, and parts usually less costly than with other molding methods.
Lost Foam Casting
Dry sand is compacted around a pattern made of expandable polystyrene (EPS) coated with a refractory wash. Molten metal is poured into the mold and replaces the EPS. The lost foam casting (EPC) process offers relatively low-cost tooling for ultra-low quantity (1-3 piece) runs.
Wood or plastic patterns directly from customer drawings
If you provide us with a drawing, we can produce a wooden or plastic three-dimensional pattern to be used to create a mold.
