Instron® started from very small beginnings…
Instron was established in 1946 in Canton, near Boston, Massachusetts. Its founders, Harold Hindman and George Burr, were working together at the Massachusetts Institute of Technology (MIT) on a joint project investigating suitable substitutes for silk that could be used in the manufacture of parachutes. After discovering there was no testing machine available accurate enough to meet their requirements, Mr. Hindman and Mr. Burr used their knowledge of electronics and mechanical engineering to design a materials testing instrument based on the latest electronics and servo-control systems. The resulting prototype was so successful that Mr. Hindman and Mr. Burr formed Instron Corporation.
The name "INSTRON” is a contraction of the words “instrument” and “electronics”, and it represents a unique partnership of these men as innovators in the materials testing machine field.
The original Instron testing machine incorporated a unique cross-head drive system, which was similar to the radar antenna positioning drive on naval warships. The transducer for the load weighing system utilized the strain gauge, which was a brand new technology developed at MIT.
Over the years, Instron has made several significant acquisitions, greatly expanding our range of materials testing systems and giving us more than 500 years of collective experience in the industry.
Severn Furnace Limited
Severn Furnace Limited (SFL) was formed in 1989 when Instron acquired the furnace product business from Severn Science Limited. SFL built its reputation in the design and manufacture of advanced high temperature furnaces and thermal equipment. Today we continue to manufacture a full range ofenvironmental chambers, furnaces, and accessories for both high and low temperature applications.
Wilson Hardness-Reicherter, Wolpert, Wilson
Wilson Hardness introduced the first Rockwell® tester to the market over 80 years ago. The company then went on to develop the legendary Tukon line of micro-indentation testers – the industry standard for Knoop and Vickers testing. Wilson also pioneered many other hardness products such as the Brale diamond indenter, Rockwell test blocks, and the Equitron Jominy fixture.
In 1993, Instron purchased Wilson Instruments and Wolpert GmbH. Today Instron’s hardness product lines include Rockwell, micro-indentation, image analysis systems, Brinell, portable testers, and a wide range of accessories. To strengthen our commitment to providing the products and technical service to fulfill our customers’ most demanding material analysis applications, we are happy to announce that Wilson Instruments will be joining Buehler, a division of ITW and a leading manufacturer of scientific equipment and supplies for use materials analysis. This union of two ITW divisions combines brands with long histories and strong reputations of market-leading technology, material analysis support, and customer service.
In 1996, Instron purchased the structural testing business from Schenck Testing Systems, which expanded our portfolio of products that test automobile performance, and formed Instron Structural Testing (IST).
Dynatup impact testing products have become a worldwide laboratory and industry standard for instrumented impact testing. The Dynatup name is synonymous with impact testing for a diverse range of materials in industries such as automotive, aerospace, electronics, medical, consumer products, and sporting goods.
Instron acquired Dynatup in 1997 and went on to launch new models in the 8100 series of drop tower test systems. Combining the proven technologies of both Dynatup and Instron, the 8100 series is recognized as the industry standard for high-energy metals testing. The 8150 model is the largest standard drop tower manufactured, delivering 28,000 J (20,500 ft-lbs) of impact energy. In addition to drop tower testing systems, Dynatup also produces instrumented tups and fixtures for pendulum impact machines.
In 1998, Instron purchased SATEC Systems, Inc. Since then, Instron has developed three new static hydraulic universal testing machines, including the LX, DX, and KN models, all of which utilize the powerful Instron control system. Today, SATEC remains the brand name for Instron’s hydraulically powered universal materials testing machines.
At the end of 2008 Instron acquired CEAST, the Italian based provider of comprehensive testing equipment for impact, rheology and thermo-mechanical properties of all polymer types. The combined experience of Dynatup and CEAST in material and structural testing markets lead to a series of developments in Instron’s impact systems, software specifications, and features, taking the best from both companies’ product lines. The result is the new CEAST 9300 series drop tower systems and the CEAST 9000 series pendulum systems.
In addition to the impact systems, CEAST brings expertise in rheological investigation with a complete line of instruments, from basic Melt Flow Testers to advanced Capillary Rheometers. Included in the CEAST testing applications are the innovative HDT Vicat Thermal-Mechanical Systems, designed to determine the behavior of plastic materials at high temperatures. These advances have allowed Instron to enhance its product offerings for the plastics industry.
Tissue Growth Technologies
In 2013, Instron acquired Tissue Growth Technologies (TGT), a premier supplier of commercial bioreactors to grow and stimulate developing tissues. TGT brings expertise with their LumeGen, CartiGen, LigaGen, CardioGen and OsteoGen technologies designed for the Tissue Engineering and Regenerative Medicine.
Firsts and Milestones
During its history, Instron has been at the vanguard of the materials testing equipment industry, scoring numerous and significant “firsts.” It was the first materials testing company to use strain gauge technologies to measure force in a materials testing machine, as well as the first to use solid-state electronics, computerized testing systems, digital electronics, digital signal processing, and infrared lighting. Also, it was one of the first companies to use video strain measurement. Further, Instron was the first in its industry to offer automatic transducers and reverse stress loading (so that electromechanical (EM) machines can go through zero from tension to compression testing).
