Simpson Technologies, a subsidiary of Norican Group, is based in Naperville, Illinois. Simpson has been an innovator in process and control technology for the foundry and process industries for over 110 years. With a focus on performance, productivity, profitability, and energy efficiency, Simpson is a global leader and trusted partner for industrial mixing solutions in process industries, as well as sand preparation, sand reclamation and sand testing equipment for the foundry industry.

History

Simpson was established in the USA by Scottish foundryman Peter L. Simpson in 1912. He introduced a muller mixer with independent muller wheel suspension. His son, Herbert S. Simpson, patented an early version of the Simpson intensive mixer. The company is still family-led: current President and CEO Bruce W. Dienst is the great-great-grandson of the founder. Simpson first introduced the concept of pneumatic sand reclamation in the 1950s. The mid-1960s saw the introduction of Simpson’s groundbreaking G series batch and continuous mixers, along with its Simpson Multi-Cooler series of continuous sand cooling and pre-mixing technology.

Simpson has grown and diversified its product line through strategic acquisitions, starting with the Standard Sand & Machine Company in 1930. Other key acquisitions include Dietert Automation Products in 1995, Beardsley & Piper in 1998 and Hartley Controls in 2000.

Simpson acquired the sand testing equipment business of R. Geroasa SRL in 1999, then added the Georg Fischer laboratory sand testing product line in 2008. Simpson is now the world’s largest supplier of foundry sand laboratory and control technology.

Simpson established Simpson Maschinen AG in 1967, a wholly owned business based in Zug, Switzerland. In 2003, Simpson and Wesman Engineering formed a 50-50 joint venture company Wesman Simpson Technologies Pvt. Ltd. in Kolkata, India to produce Simpson equipment for the Indian market.

Webac Gesellschaft für Maschinenbau mbH in Euskirchen, Germany together with its subsidiaries Webac Maskin AB in Stockholm, Sweden and Webac s.r.o. in Pribram, Czech Republic acquired by Simpson in 2018. Webac was originally a licensee of the Beardsley & Piper Speedmullor®. Since the acquisition, many technologies from Webac have been added to the Simpson product line and vice versa. The Simpson Speedmullor® is manufactured in Euskirchen and in the USA.

A committed supporter of industry trade bodies, Simpson has both funded and led prestigious organizations like the American Foundry Society (AFS). Elected in 2015, Bruce W. Dienst was the 4th consecutive generation of the Simpson family to serve as AFS President. In 2022, Simpson joined Norican Group as one of its subsidiaries. Simpson also supports the North American metal casting industry through the financial support of the Foundry Educational Foundation. Simpson has been a continuous supporter of FEF every year since its inception in 1947 and Simpson Past President Bruce L. Simpson was a member of the original FEF Board of Trustees.

Headquarters

In 1991, Simpson relocated to its headquarters, a 3,000 square-meter facility in suburban Aurora, Illinois. In April 2024, Simpson moved its global tech center to Naperville, Illinois.

Products

Simpson manufactures and maintains a range of mixers plus sand preparation, testing and reclamation equipment at its locations in the USA and Europe. Mixers form the majority of its production.

Intensive Mixers

Intensive mixers blend materials with disproportionate mass, particle size, liquidity, viscosity, or density (often known as “wetted solids”) into a completely uniform whole.

Simpson Mix-Muller® Batch Mixer

The Simpson Mix-Muller is a medium-speed, high-intensity, muller-type mixer for batch operation. With thousands of global installations, it is widely used across many different process applications including explosives/pyrotechnics, catalysts, ceramics, animal feed, architectural stone, pharmaceuticals, pigments, batteries, and powdered metals.

Its mixing quality, energy efficiency and flexibility also make it very popular for batch mixing foundry sand.

Simpson Multi-Mull® Continuous Mixer

The Simpson Multi-Mull is a medium-speed, high-intensity, muller-type mixer for continuous operation in medium to large-sized continuous processing systems or mixing applications.

It is widely used in chemical processing industries, with mixing applications that include chocolate, ferrites, fertilizers, lead pencil graphites, mineral ores and welding rod flux.

The Multi-Mull is also frequently installed to continuously mix larger volumes of foundry sand. Delivering up to 50% more hourly production than two batch mixers of equivalent diameter, it produces larger volumes of molding sand at a lower cost of installation and operation than any other mixer in the world.

Sand Preparation

Simpson’s range of mixers, control technologies and other equipment work together seamlessly to provide a complete sand preparation solution with consistently high-quality sand and minimal process variation. Simpson’s sand preparation range includes the two mixers listed above.

Simpson Speedmullor® Batch Mixer

The Simpson Speedmullor is a high-speed, high-intensity, muller-type mixer for batch operation that combines the mixing performance and energy efficiency of mulling with the productivity of a conventional high-speed, high-intensity mixer.

Flexible enough to cope with smaller batches and shorter cycle times, it consistently delivers better, cooler sand and outstanding energy efficiency for medium- to large-sized sand systems. It can lower sand preparation energy costs by 30% or more.

Simpson Hartley Online Control, Automation & Dosing

A range of complete green sand mixer group control and automation systems, the Simpson Hartley machines automate and precisely control mix preparation, dosing and machine function for any make and model of green sand mixer for both batch and continuous mixing processes.

The Hartley and BFS dosing machines provide continuous dosing of dry materials (primarily bentonite clay) to a continuous cooler or continuous muller in a fully automated sand mixing system.

Simpson Multi-Cooler® Sand Cooler

The Simpson Multi-Cooler is a continuous sand cooler and pre-conditioning system that employs evaporative cooling. By pre-mixing returned foundry sand and keeping it at a lower, more consistent temperature, the Multi-Cooler helps the muller produce high quality sand that consistently stays within specification.

Other sand preparation equipment

Other equipment includes rotary polygon screens which continuously screen foundry return sand, bucket elevators for material transport and over-belt aerators which gather molding sand from conveyor belts and throw it back onto the belt, parallel to its direction.

Sand testing

Sand testing equipment helps foundries better control their materials and processes to reduce defects. Simpson is the world’s largest supplier of sand laboratory and control technology. Foundries can pick from a wide range of equipment to enhance their current testing operation or to set up a completely new laboratory.

Sand reclamation

The Simpson Pro-Claim® Continuous Sand Reclaimer inexpensively reclaims large volumes of chemically bonded and green sand for reuse in molding systems. In addition to reducing the consumption of new sand and minimizing disposal cost, its pneumatic process is the most energy-efficient available. Simpson understands that no two foundries are exactly the same in their combination of sand, binder and operating conditions. The Simpson Performance Laboratory will test your foundry’s sand or ceramic and select the optimum reclaimer for your particular system requirements. The Pro-Claim is CE certified and can be sold in Europe. For small foundries and laboratories, the Even-Flo is the ideal sand reclamation solution.

Other Simpson technologies

First introduced to the metal casting industry in the 1930s, the Simpson Sand Slinger is an advanced, green sand molding system for the production of large flask molds. WEBAC core sand ball mixers combine reliability with a robust, long-lived design to deliver excellent mixing results.

The Simpson SF Series Shell Core machines automate coremaking to save on labor costs and consistently produce top quality cores.
