WELCOME TO OUR WEBSITE

Applied Spring Technology Limited (AST) specialises in the design and manufacture of Constant Force and Constant Torque springs.

Our philosophy is based on “Close to the Customer” - working in partnership with them from design idea through to successful application.
Ideally located in the village of Hartwell, amidst the rolling Northamptonshire countryside, just 5 miles from Junction 15 of the M1, it is apt that our philosophy and exceptional levels of customer service has prompted comment that working with AST is “like a breath of fresh air!”
