You do not need a finalized drawing to start a discussion. Send the information currently available and our team can review the manufacturing feasibility.
Send PDF, CAD or other technical drawings with dimensions and performance requirements.
Existing spring samples can be evaluated when complete drawings are unavailable.
Provide dimensions, load, material, estimated quantity or operating conditions.
Tell us where the spring is used and what mechanical function it needs to perform.
Quality control begins with incoming material and continues through spring forming, secondary processing and final inspection.
Our IATF 16949 quality management system supports structured process control, traceability and inspection for automotive and demanding industrial OEM applications.
Inspection documentation can be prepared according to specific customer and project requirements.
Learn More About Quality Control →Our production capabilities extend beyond spring forming. Depending on the part and customer requirements, secondary operations and automated processing can be integrated into the manufacturing process.
This helps reduce supplier complexity and provides better control from prototype development through repeat production.

A multi-part European sourcing project demonstrating our ability to support customers from initial RFQ through prototype validation and preparation for volume production.
A German customer approached GL Springs with a sourcing project covering more than 20 different custom spring parts, each with different dimensions, materials and manufacturing requirements.
Rather than treating the project as a simple quotation exercise, our team supported the customer throughout the complete development process.
During prototype development, several drawings and manufacturing processes were adjusted based on actual testing and application requirements.
Our engineering and production teams supported drawing review, technical clarification, prototype manufacturing and sample validation across the project.
After successful sample testing, the customer is now preparing the project for volume production.
This project demonstrates our ability to support complex multi-part spring sourcing programs—not only individual components.
Discuss Your ProjectA structured development process helps move your custom spring project from initial requirement to stable production.
