DIS was a pioneer in the development and introduction of seismic isolation technology. Dynamic Isolation Systems helped to develop codes and provided design and analysis support to engineers and government agencies. Over the past 30 years DIS has continued to develop its isolators in response to ever-increasing performance requirements.

Dynamic Isolation Systems has provided over 15,000 isolators for more than 300 bridges and buildings worldwide. Prominent projects include the iconic Golden Gate Bridge, San Francisco City Hall and the 1.7 million square-foot Tan Tzu Medical Center in Taiwan.

Our engineers provide technical support and parameters for structural modeling. Dynamic Isolation Systems will assist you with your feasibility study, budget development and value engineering. On projects where DIS has participated from the design/concept phase, costs have been reduced by up to thirty percent.

• Facility
Dynamic Isolation Systems’ state-of-the-art 60,000 square-foot plant is located in Reno, Nevada, USA. All major steps of our manufacturing process are completed on-site. Because we don‘t out-source we’re able to maintain the highest production and performance standards in the industry.

• Molding Press Capabilities
Isolators are molded in custom-designed and built mold presses with capacities ranging from 200 to 4,400 tons. In response to increased demand for larger-sized isolators, DIS now has four presses of over 2,000-ton capacity. We have manufactured isolators as large as 60 inches in diameter and weighing 10 tons each.

• Machining
Steel processing is a major part of manufacturing our isolators and hardware. Several large, computer-controlled machining centers process our steel plates. They have the capacity to machine plates up to 80 inches wide

• Testing
Our main test rig has a shear displacement of ± 31 inches, a shear force capacity of 700 tons and an axial force capacity of 2,000 tons. Testing is also conducted in a smaller machine that has a shear displacement capacity of ± 12 inches, a shear force capacity of 100 tons and an axial force capacity of 600 tons.
