Extension Springs can be used for many applications and come in a vast variety of materials and finishes. At Xulong Spring, we can custom make any type of extension spring to meet your specifications. Regardless of the industry, quality, custom extension springs are always in high demand. They can be found in almost anything from simple, old machinery to complex medical devices to satellites. Peninsula Spring excels in custom extension spring design and supplies a wide variety of customers in the computer, medical, aerospace and defense industries.

Using CNC spring coiling machines, we can produce custom extension springs with wire diameters from 0.08mm to 35mm in the way of cold wounding and hot wounding.

Our tech dep can design springs to have initial tensions according to the load requirement of your applications. We will also validate spring designs before manufacturing, and secondary processes such as color-coding, plating, and heat-treating are must for extension springs to make sure high quality.

Q) What is the function of an extension spring?
A) To provide extended force when the spring is pulled apart from its original length.


Q) How do extension springs absorb and store energy?
A) By offering resistance to a pulling force. Various types of ends are used to attach the extension spring to the source of the force.


Q) Concerning extension springs, where do most failures occur?
A) Most extension spring failures occur in the area of the end. To maximize the life of the spring,the path of the wire should be smooth and gradual as it flows into the end.


Q) What needs to happen for an extension spring to have no initial tension?
A) The Extension Spring needs to be designed with space between the coils.
