Compression Springs
KLF is able to provide compression springs in a variety of shapes and sizes. A compression springs is a mechanical spring with elasticity, it is an open-coil helical spring, which usually coiled into a constant diameter shape, such as a cylindrical spring, conical spring, concave spring, or convex spring. We can provide carbon steel springs, stainless steel springs and non-ferrous alloy springs with wire diameter range from 0.1mm to 6mm. Our compression springs are primarily used in water dispenser, water cooler and air conditioners. Following shows the spring examples and custom made details.
Compression Springs, Conical Springs, Tapered Springs
- KLF provides conical compression springs with the wire diameter range of 0.1mm to 1.5mm and made of a variety of materials. We use a CNC automatic spring machine, and a camless spring machine to manufacture the small tolerance precision spring.
The conical spring has a variable coil diameter. It has a large diameter at one end and a small diameter at the other end, with the diameter of the middle coil constantly changing.
Compression Springs, Valve Spring
- Valve springs are a helical compression spring used to close or keep the valve closed. As a professional precision spring manufacturer, KLF is able to customize valve springs for a variety of valves and applications, such as valve springs used for automotive, natural gas, medical equipment, mining and other industries.
KLF produces valve springs in a variety of materials including high carbon steel wire, stainless steel wire, non-ferrous metal alloy wire.

As a professional manufacturer of customized compression springs, KLF is able to design and precisely manufacture compression springs in a variety of shapes and sizes to meet strict customer requirements. In addition, we designed a braid packaging method to solve difficult installation problems and long term consumption for customers in mass production. The spring is braided with paper tape, allowing the customer to directly use the automatic insert machine in order to assemble the spring, at a speed of 300 springs/minute, thus effectively reducing customer production costs.
