The Right Process and Alloy for Every Product

With so many varied techniques and processes to choose from, our experts are free to select the molding, core making and casting methods that will produce your castings with optimum results.  To assure you of the most cost-effective blend of quality and production, Eck engineers often become a partner in the design process, making suggestions that will give you the best results.

The brief descriptions that follow will highlight the areas of application and advantages of each process, along with our special capabilities in each.  

Green Sand Innovation

Green sand molds are ideal for producing complex castings in low, medium or high volume.  Olivine green sand techniques are the heart of a foundry, and we offer conventional match plate and cope & drag production in flask sizes up to 30" x 36".

Shell Molding Capabilities

Shell molding offers a method of producing intricate castings with thin sections and minimum draft, such as air-cooled engine cylinder heads.  A resin-coated sand and a heated pattern results in a shell mold of controlled thickness and strength.  Complex cores are also produced quickly by shell molding for use in all casting processes.

Programmable Controlled Core Making

Free Radical Curing (FRC) core making offers speed, flexibility, dimensional accuracy and repeatability for the production of cores; producing a top quality internal finish on castings.  Coupled with our core process equipment is a state of the art gas generation system and fume process scrubber which acknowledges Eck's commitment to protecting both operator and environment, truly a current technology core making work cell.

Air Set Versatility

One-of-a-kind or production castings can be made interchangeable using either of our Just-in-Time fully Flexible Airset lines.  A central distribution system for chemically bonded airset sand is surrounded by a variety of molds and core boxes in many shapes and sizes.  The layout lets the operation move quickly from one pattern to the next, producing the molds needed for production without changing a setup.

Permanent Mold Configurations

Permanent mold and semi-permanent mold casting processes are best for medium to long runs.  Our broad range of tilt pour permanent mold equipment, as well as self-contained devices and standard hydraulic devices, assures optimum metal flow and high casting integrity for your designs, up to 100 pounds.  Semi-permanent mold capabilities incorporate additional features such as sophisticated internal cores for more complex castings.

Low Pressure Permanent Mold

The low pressure permanent mold process is an attractive alternative to conventional permanent mold for some casting shapes.  Symmetrical castings such as wheels and sheaves are good candidates for this process.  Increased yields, high casting densities, reduced cleaning requirements and the ability to produce complex contours on the outside of the casting by using hydraulically actuated coring are some of the advantages available to our customers.  Internal sand cores can be added for more complex designs.

Low pressure machines, in a specially designed bay at our Manitowoc facility, provide production capabilities to meet your needs for castings in weights from one to 150 pounds, in volumes ranging from under 1,000 to 100,000 per year.

Alloys

From A356 aluminum to high-performance metal matrix composites, Eck Industries pours most aluminum alloys. We are specialists in A201 and A206 alloy castings, when strength and toughness are a primary concern. Aluminum metal matrix composite materials produced in our foundry are in use in applications from automobiles to semiconductor manufacturing equipment. Our staff can help you match your casting application with the right alloy.
