Extension spring assortment
The extension spring assortment has hooks, eyes, or other linking devices at both ends, so they are able to expand and extend under load to help absorb vibrations or shocks.
Extension spring assortment is wide，Able to provide customers with a wide range of spring designs, sizes and specifications. We are able to provide our customers with many different sizes of stretch springs, you may find 50 or 100 springs with the same outside diameter, but the rest of the dimensions (such as wire diameter and hook inside length) will be completely different. These dimensions are taken from standard dimensions, such as those on the bit size table. Therefore, the variety of tension springs is related to its different specifications and sizes.
Extension spring assortment is one of the most competitive aspects of the spring industry. HSPR differentiates itself from the competition with the quality and experience of our springs, and we are able to offer the largest selection of springs in the industry. A variety of sizes of mixing, compression and tension combinations and torsion spring combinations to meet your needs.
Used in almost all industries, extension spring assortment are ideal when a precise force with a specific amount of deflection is required. Tension springs provide force by stretching, usually they are cylindrical helical springs formed by circular wires, with mechanical rings, crossed center rings, or machine springs.
A extension spring assortment is a mechanical spring characterized by tightly wound spiral coils that undergo elastic deformation when they absorb a tensile load. These tensile loads cause the length of the spring to extend. Like other springs, their primary functionalists store and release energy by resisting the external tension applied to the end of the spring. This resistance stores energy and creates a force in the opposite direction of the spring’s stretching.
Application field of extension spring assortment:
- Medical: Stretch springs can be used in medical devices, such as surgical instruments and equipment, where controlling extension and contraction is critical.
- Aerospace: Stretch springs are essential in the aerospace industry for special applications such as seats, landing gear, cargo systems and doors.
- Construction: Stretch springs are designed for use in a variety of construction applications that require controlled stretching, including scaffolding and temporary bracing.
- Electronic and electrical equipment: Stretch springs can be used in electronic devices such as switches, connectors, and wire management systems to provide tension and control.
Rigorously test and measure your stretch springs to meet your every parameter:
- Material testing: We monitor every batch of wire submitted for testing and prototyping to ensure the highest quality of the product.
- Dimensional accuracy: This involves measuring key dimensions of the stretch spring, such as wire diameter, outside diameter, length, and number of effective coils. This ensures that the spring meets your specified design requirements.
- Load test: This test involves applying various loads to the stretched spring to verify that it can stretch and contract without any deformation or failure. Load should be applied gradually to prevent sudden overload.
- Elastic and stress tests: This test assesses the ability of the spring to recover after stretching. It measures factors such as elastic modulus and yield strength to ensure that the spring can withstand the expected load.
- Fatigue test: Tensile springs are usually subjected to repeated loading and unloading cycles. Fatigue testing simulates these conditions to ensure that the spring can withstand the expected number of cycles without failure.
- Load test: This involves applying a load to the spring and measuring the corresponding deflection. This helps characterize the behavior of the spring under different loads.
- Visual inspection: Visual inspection of the spring is essential to identify any surface defects, such as cracks, pitting, or other anomalies.
No matter what kind of wire and wire diameter you need, we can provide, you send us drawings, we can customize according to your specifications.
With 37 years of experience at HSPR, our engineers can help you design your ideal stretch spring. Using high-quality materials, we check every batch of springs to ensure that we produce extension spring assortment that make your application more stable and reliable.
