What Are Custom Springs?
Custom springs are made-to-order mechanical components designed to meet specific load, dimensional, and material requirements that cannot be satisfied by off-the-shelf parts. At Springtech, we manufacture all springs from scratch — ensuring that every component we deliver meets the performance criteria of your application.
Our in-house engineering and validation ensure every design is optimised for lifecycle performance and compliance.
