Tension Spring Calculation Formula

Spring Constant: denoted by k, the load in kgf/mm per 1 mm distance increase when the spring is stretched.

Spring Constant Formula (unit: kgf/mm): k=（G*d4）/（8*Dm3*Nc）

G: steel modulus of the wire; d: wire diameter; Dm: center diameter = outer diameter – wire diameter; Nc: effective number of turns = total number of turns – 2.

Initial Tension of Tension Springs: Initial tension is the force required to just separate the coils that are in close contact. This initial tension is developed after the spring is coiled. Due to variations in wire material, diameter, spring index, static electricity, lubricants, heat treatment, and plating, the initial tension in each tension spring may vary. Therefore, when installing tension springs of different specifications, they should be pre-extended so that there is a slight gap between the coils. The force required at this point becomes the initial tension.

Initial tension = P-k X l = Maximum load – spring constant X extension length

Characteristics of Tension Springs

Various end devices or “hooks” are used to ensure the source of tension for tension springs. Tension springs operate in a manner opposite to that of compression springs. While compression springs exert a force when compressed, tension springs exert a force when extended or pulled apart. When the ends of a tension spring are pulled apart, the spring attempts to pull them back together. Like compression springs, tension springs also absorb and store energy. However, unlike compression springs, most tension springs are typically under a certain amount of tension even without any load. This initial tension determines how tightly the tension spring is coiled in the absence of any load.

Custom Tension spring Process

Confirm Spring Specifications

The first step in our custom torsion spring process is to confirm the specifications. This begins with a detailed consultation where our expert team discusses your specific requirements, including dimensions, materials, load requirements, and the intended application of the springs. After understanding your needs, our engineers will provide a custom design and specifications for your approval. Once the design is approved, we will provide a detailed quotation based on the confirmed specifications and order quantity.

Factory Production

Upon approval of the specifications and receipt of your order, we proceed to the production phase. We start by selecting the appropriate high-quality materials for your torsion springs. Utilizing advanced technology and precise manufacturing processes, our skilled technicians produce the custom torsion springs to exacting standards. Throughout the production process, we conduct stringent quality checks to ensure that each spring meets the specified standards and performs reliably in its intended application.

Shipping

Once the production of your custom torsion springs is complete, we carefully package the springs to prevent any damage during transit. We then arrange for prompt and secure shipping to your specified location, whether domestic or international. To ensure your complete satisfaction, we offer comprehensive after-sales support, ready to address any questions or concerns you may have after receiving your order.
