Introducing  Innovation in Energy Storage and Space Optimization

At Zhuji Bosswinn Springs Co., Ltd. , we are dedicated to the research, development, and precision manufacturing of high-quality metal hardware accessories, including auto parts, home appliance components, and electronic spare parts -1. Within our comprehensive range of spring solutions, our Conical Wire Compression Springs stand out as a testament to our commitment to engineering excellence and innovation. These springs are expertly designed to meet the demands of modern applications where space is at a premium and performance is non-negotiable.

What is a Conical Compression Spring?

A conical compression spring is a type of open-coil helical spring with a distinct shape: its radius progressively decreases from the base to the apex, giving it a tapered or cone-like appearance -1. This unique geometry is not merely aesthetic; it is the key to a host of functional advantages. Unlike traditional cylindrical springs that have a constant diameter, conical springs are engineered to provide a telescoping effect when compressed, allowing the coils to nest within one another -

Unmatched Advantages in Design and Function

The primary advantage of Bosswinn's conical springs lies in their ability to achieve a significantly reduced solid height—the dimension of the spring when it is in a maximum loaded condition -1. When fully compressed, the spring's height is approximately equal to the thickness of the wire or the base coil, which is dramatically shorter than a standard spring with a similar load capacity. This feature is ideal for applications with stringent axial space limitations, such as the battery springs commonly found in electronics -1.

Furthermore, our conical springs offer enhanced stability. Their tapered shape makes them inherently more resistant to buckling—a common issue with slender cylindrical springs under load. They are specifically designed to exhibit a non-linear load-deflection characteristic, meaning the spring rate (the change of load per unit deflection) increases as the spring is compressed -1. This happens because the larger, more flexible coils at the base progressively come into contact with the smaller, stiffer coils at the apex, providing a progressive resistance to force.

Precision Engineering and Manufacturing with Key Physical Parameters

At Bosswinn, our conical compression springs are born from a meticulous manufacturing process that ensures durability and peak performance. We utilize high-quality materials, typically steel alloys such as high-carbon steel or stainless steel, selected for their specific mechanical properties -

. Our production process incorporates advanced techniques to enhance the springs' fatigue life and resilience. We also utilize a specialized creep tempering process to minimize thermal relaxation and attenuation, ensuring the spring maintains its intended force and dimensions even in demanding thermal environments.

Our manufacturing capabilities are defined by precise physical parameters to meet exact customer specifications:

• Wire Diameter: We can produce springs from wires with a diameter as small as 0.1mm up to 8mm, offering flexibility for both micro-electronic components and heavy-duty industrial applications -
  .

• Material Options: We work with a wide range of materials, including music wire (carbon steel), stainless steel, and alloy steels such as 51CrV4, SEA9260/9254, and SUP grades -2.

• Custom Dimensions: We manufacture springs to specific customer requirements for Outside Diameter (the surface of the coil), Free Length (length when unloaded), and Hole/Rod Diameter (the mating part dimensions) to ensure perfect integration into any assembly -
  .

• Load at Solid Height: Each spring is engineered to provide the precise load value needed to completely deflect the spring to its solid height, ensuring reliable performance under maximum load conditions -
