What are Extension Springs?

Extension springs, also known as hook-end extension springs are versatile mechanical devices that exert a contracting force when stretched, pulling two objects closer together. Extension springs find widespread use in various industries and everyday items. They are commonly found in appliances, furniture, automotive interiors, and numerous other applications. The flexibility and customization possibilities make extension springs an ideal choice for many compact spring solutions. Their ability to absorb and store energy makes them essential components in a wide range of applications, including automotive, aerospace, industrial, and more.

Extension Spring Customization Options

At Custom Spring Manufacturing, we understand that every application is unique. Our objective is to offer comprehensive customization options for your hook-end extension springs, ensuring they meet your specific needs. With a wide array of choices, including inner and outer diameter, overall length, wire diameter, wire material, and hook shape and size, we can create extension springs precisely tailored to your requirements.

When it comes to extension springs, Custom Spring Manufacturing offers a wide range of options to customize the end shape, ensuring the perfect fit for your specific application. Here are some of the available end shape options:

• Open Loops: This is a common end shape for extension springs, where the end coils form open loops. These loops provide easy attachment points, allowing the spring to be connected to other components using hooks, pins, or other fasteners.
• Machine Hooks: Machine hooks are tightly wound coils at each end of the extension spring. These hooks provide a secure attachment point, ensuring that the spring remains in place while under tension. Machine hooks are commonly used when the spring needs to be securely connected to other parts of a mechanism.
• Extended Hooks: Extended hooks feature elongated coils at each end of the extension spring. These hooks provide a larger surface area for attachment, making them ideal for applications where a stronger connection is required. Extended hooks offer enhanced stability and can withstand higher levels of tension.
• Swivel Hooks: Swivel hooks are designed to rotate freely, allowing the extension spring to move in different directions without causing stress or binding. These hooks are useful in applications where the spring needs to rotate or twist during operation, minimizing friction and ensuring smooth movement.
• Custom End Shapes: Custom Spring Manufacturing also offers the flexibility to design and produce extension springs with unique and custom end shapes. Depending on your specific requirements, our team of experts can work with you to develop custom end shapes that perfectly align with your application’s needs.

Please note that the availability of specific end shapes may depend on factors such as wire diameter, coil count, and overall dimensions of the extension springs. Our team is ready to discuss your requirements and guide you in selecting the most suitable end shape option for your extension springs.
