About Us

A Proud Tradition of Leadership in Temperature Control Technology

Since its founding in 1966, Gammaflux has set an uncompromising standard: to design and produce the most technologically advanced, highest-quality temperature control systems for the plastics industry. Because of this, the company has an excellent reputation globally as a product and service leader and innovator.


Gammaflux is more than just a supplier to our customers - we consider customers to be partners in the ongoing search for the best, most productive, and most cost-effective temperature control solutions possible.

Most Gammaflux temperature controllers are used on hot runner injection molding applications. However, they are also frequently used for controlling a wide variety of other plastics industry processes including thermoset, liquid injection molding (LIM), reaction injection molding (RIM), injection and extrusion blow molding, thermoforming, pipe/profile/sheet extrusion, and more.

These processes all have something in common: they all require temperature control. And if the temperature controller for any of these applications fails, the process either stops or is crippled. When this happens, who will you turn to for assistance?

When selecting a temperature control supplier, keep in mind that you are selecting a partner whose support is critical to your product and your profitability. Gammaflux is proud to partner with its customers and provides the consultative service and support you need to achieve success.

A Commitment to Quality, A Dedication to Development

Gammaflux is founded. The Goddard Flight Center in Maryland is the new company’s first customer.


The 2000 Series manual controller is introduced.


A 2000 Series Gammaflux solid state rheostat control panel survives a major, devastating fire in a Ford automotive plant, proving its durability. Once word of this accomplishment spreads, Ford orders many more of these control panels.


The 3000 Series automatic and manual controller is introduced. The automatic control portion is a PID controller with phase angle firing.


The 6000 Series controller is designed to incorporate new features into the earlier 5000 Series, including a newly designed power supply.


Gammaflux introduces the 900 Series Hot Runner Temperature Controllers, quickly establishing the industry standard for both control performance and reliability leading to Gammaflux's rapid growth. The 900 Series also introduces our revolutionary PID² adaptive tuning technology, which allows the system to actually anticipate changes in temperature instead of reacting after the fact. PID² is the most effective and fastest-responding control technique available and continues to be the basis for all Gammaflux controllers to this day.


The company’s new owners use their winning combination of investment savvy, marketing expertise, and engineering know-how to institute an aggressive program of product and technology enhancements, committing to virtually annual introductions of new products.


The 9000 Series heralds a new era for the industry as the first microprocessor-based hot runner controllers to incorporate PID2 technology, combining industry-leading analog control capabilities with the latest digital technology and affording unprecedented levels of control over the hot runner process.


The 9500 Series introduces several important ease-of-use features, including touch-screen operation and up to 128-zone control.


New Mold Doctor® software greatly expands the troubleshooting diagnostics on the 9000 and 9500 Series controllers. Fault, wiring, thermodynamic and historical reports once again push the boundaries of hot runner diagnostics.


Gammaflux opens offices in Germany, reflecting the growing international popularity of the company’s product and service lines.


The industry’s first truly global controller, the GLC-2K provides seamless operation in any country and features a compact, modular enclosure.


At the K 2001 fair in Dusseldorf, Germany, Gammaflux introduces its new TTC Family of hot runner temperature control systems. This new line of controllers employs a host of new features, including a smaller footprint and an attractive price. In addition, the TTC2200 Panel Mount controller is designed for seamless integration into any injection molding machine’s control panel.


The new LEC line of temperature controllers is introduced at K 2004 in Dusseldorf. Available for applications from 2 to 24 zones, this new line of controllers provides molders with full-featured hot runner temperature control at an extremely competitive price.


Gammaflux adds major functionality upgrades to its website, including multiple languages and on-line quoting and ordering capabilities.


At NPE 2012 in Orlando, Florida, Gammaflux introduces its new G24 'next-generation' line of temperature control systems. The G24 line provides numerous new benefits including a lower price, smaller footprint, faster performance, and advanced connectivity options.


Gammaflux Controls Inc. is now world renowned as the undisputed leader in the hot runner control industry, with systems in place in 50+ countries.


Gammaflux looks to the future with a focus on continually developing new ways to make plastics processing easier, more cost-effective, and more efficient.


The timeline above shows an impressive list of accomplishments since Gammaflux was founded in the 1960s. The Gammaflux name has long been synonymous with the highest technology and quality standards. Our systems are known for their reliability and durability under the most rugged of factory conditions. In fact, most of our customers report excellent results from Gammaflux controllers even after many years of demanding operation in their plants.

Since the early 1990s, Gammaflux has been introducing new products and technologies at an unprecedented rate. Many of these new products are the direct result of an ongoing dialogue with our customers to determine precisely what they need to improve their applications. Thanks to the dedication of our design, engineering and manufacturing teams, the Gammaflux standard has not only been upheld through these extremely dynamic years, but we've actually surpassed our customers' goals in many cases.

The plastics industry is dynamic and it continues to evolve at a rapid pace. Processors are challenged daily to meet or exceed lean manufacturing initiatives, and achieve the highest possible quality and productivity goals. Gammaflux will continue to stay ahead of this curve, providing the best temperature control products and technologies to support its customers and help them meet these objectives.
