Spray Recovery System has environmentally friendly design.

Press Release Summary:

CESAR™ (Contain, Evacuate, Separate And Recover) vacuum pattern spray recovery system helps provide cleaner, safer sand foundry work environment. In operation, this closed-loop system executes containment and collection of unused sprayed materials; air-powered, vacuum-evacuation removal of spray fumes; cyclonic separation of usable liquid from the fumes; as well as recovery, recycling, and reuse of fluid. Operation also contributes to environmental initiatives.

Hunter Introduces CESAR(TM) Environmentally Friendly Vacuum Pattern Spray Recovery System at CAST EXPO 2013

New technology provides safer, cleaner work environment, as well as cost savings, for foundries by capturing and recycling unused pattern spray.

SCHAUMBURG, IL — Hunter, the first name in automated matchplate molding machines and mold handling equipment, announced today the introduction of its new CESAR™ vacuum pattern spray recovery system. The CESAR system was first made available to the world market recently at the company’s Cast Expo 2013 Booth #473, where it was mounted on the new Hunter HLM-10 linear motion molding machine. CESAR ran throughout Cast Expo 2013, one of the foundry industry’s leading events, held April 6-9th at America’s Center in St. Louis, MO.

According to Hunter Foundry Machinery Corporation president and CEO Bill Hunter, who invented the system, “CESAR” stands for Contain, Evacuate, Separate And Recover. “This relates to the proper disposition of pattern spray typically used in sand molding operations, to act as a release agent between the mold and the pattern plate,” Hunter said. “We invented it in response to our customers’ needs, in recognition both of modern foundry and global environmental standards and to help improve their return-on-investment (ROI).

In operation, the closed-loop CESAR System from Hunter executes the following:

• Containment and collection of the unused sprayed materials

• Air-powered, vacuum-Evacuation removal of the spray fumes

• Cyclonic Separation of the usable liquid from the fumes, And

• Recovery, recycling and reuse of the fluid.

Most typical molding machines include a spray head positioned in the sand filling station and a spray evacuation device positioned near the rotary cradle or the spray head.  The spray is then dispersed onto the pattern plate as it enters the rotary cradle. But uncontained, excess spray can go onto other parts of the machine, as well as into the foundry atmosphere. This is why Hunter created its new CESAR System.

“In our new CESAR System, the evacuation device – a slotted tube on the circumference of the rotary cradle – connects to an inline vacuum pump. Then, a cyclonic separator and water separator capture release agent vapor from the air collected in the tube,” Hunter stated, adding that CESAR provides a cleaner, safer working environment in the sand foundry while providing not only substantial savings to a foundry’s operation but also a positive environmental benefit to that foundry’s “green” initiative.


Hunter Foundry Machinery Corporation was founded in 1964 as Hunter Automated Machinery Corporation with the invention of the first gravity-filled automated matchplate molding machine. This development established the company’s history of innovation and launched the foundry industry into a new industrial revolution. Pioneered by William “Al” Hunter in his garage, the original HMP-10 machine streamlined the laborious metal casting process by offering foundries unimagined new production capabilities, producing as many molds in one hour as most had been able to produce in an entire day. As industry demands grew, Hunter responded with advanced solutions such as automated mold handling equipment and coresetters.

Now in its 50th year, Hunter Foundry Machinery Corporation's inventions have earned nearly 150 patents around the world. With more than 1,800 molding machines and mold handling systems installed around the world, the Hunter sales and service reach extends from its manufacturing sites in North America, South America and China through its offices in the U.S., Europe, Brazil, India and Shanghai to every corner of the globe. Sales and technical support, as well as the company’s $12 million parts inventory, serve to maintain each machine's original production capability, as well as Hunter’s preeminence in the world market.
