Conical Springs - Product Details

1. Product Overview & Name:

• Product Name: Conical Springs (Also known as Tapered Springs or Cone Springs)

• Description: Conical springs are a specialized type of compression spring characterized by their tapered, cone-like shape. This innovative design allows each coil to nest neatly into the adjacent one,  often completely flat. This makes them an ideal solution for applications where space is limited and a low loaded height is critical.

2. Key Features & Advantages:

• Space Optimization: Their ability to compress fully into a flat stack provides a significantly lower solid height compared to traditional cylindrical springs of similar mass and deflection.

• Progressive Force Characteristic: The tapered design often creates a non-linear, progressive spring rate. Softer coils engage first, providing a lighter initial force that progressively increases as the larger coils begin to compress. This offers superior shock absorption and stability.

• High Stability & Reduced Buckling: The conical shape provides a wider base, granting exceptional lateral stability and resistance to buckling under load, even without guide mandrels or sleeves.

• Multiple Loading Options: Can be designed to load at the top (small end), base (large end), or across the entire face of the spring.

• Customization: Available in various materials, wire diameters, and tapers to meet specific force, travel, and space requirements.

3. Technical Specifications (Typical):

• Materials: Stainless Steel (302/304/316), Music Wire (ASTM A228), Oil-Tempered Wire, Phosphor Bronze, Beryllium Copper, and other specialty alloys.

• Wire Diameter: Range from miniature springs (e.g., 0.1mm) to larger industrial sizes (e.g., 5.0mm+).

• End Types: Can be manufactured with open ends, closed ends, or ground ends to suit specific mounting and load-bearing needs.

• Finishes: Zinc plating, Nickel plating, Powder coating, Passivation (for stainless steel), or other corrosion-resistant finishes upon request.

• Standards: Can be manufactured to meet international standards such as ISO, DIN, JIS, or custom-designed to customer prints and specifications.

4. Applications:

Conical springs are versatile components used across numerous industries:

• Automotive: Clutches, transmissions, valves, suspension systems, and shock absorbers.

• Electronics & Appliances: Tactile switches, keypads, battery contacts, and actuators where a low profile is essential.

• Industrial Machinery: As vibration dampeners, return mechanisms, and in presses where variable force is required.

• Aerospace: Landing gear systems and other applications demanding high reliability and space efficiency.

• Medical Devices: Used in drug delivery systems, surgical tools, and portable medical equipment.
