Differentiated precise forming of single-piece, thin-walled components
Standex ETG leverages deep expertise in expansion forming to deliver precision components with superior dimensional accuracy and repeatability to a wide range of aerospace and defense customers. Our Spincraft facilities in Massachusetts and Wisconsin house custom-designed, CNC-controlled expansion equipment engineered for both standard and highly specialized applications. We help our customers meet the most demanding specifications with confidence.
Expansion forming is a precision metal forming process that utilizes the even application of force to push material past its yield strength, achieving shapes that result in a relatively stress-free product. This tactic increases the diameter or profile of tubular and cylindrical components through controlled internal pressurization.
Our expanders utilize proprietary coatings and interlocking designs to reduce visual impressions, allowing for even pressurization during the process. This results in parts with exceptional surface quality and performance.
Using expansion forming technology can:
Our forming portfolio includes custom-built and fully CNC-controlled equipment that allows for forming pressure capabilities up to 680 tons. We can expand part sizes anywhere from 3 inches to 12 feet in diameter. Our current height capacity is 75 inches and we maintain a tolerance capability of +/- .002 inches.
Standex ETG’s Spincraft businesses have extensive expansion experience with a wide range of materials, including:
