A range of compression springs from our Bosswinn offer, available in various sizes and lengths, with closed and ground or closed not ground end types. Compression springs are highly popular as they can store a large amount of energy in a small space, making them ideal for a wide range of applications.
These Bosswinn compression springs, also referred to as coil springs, have varying degrees of stiffness, also known as spring rate. Coiled springs are designed to return to their original height when compressed, helping to keep components separated and functioning properly.
Bosswinn offers a great selection of compression springs with wire diameters ranging from 0.2 to 2.2 mm and spring rates from 0.06 N/mm to 22.56 N/mm.
Features and Benefits:
Coil spring design ensures strength and flexibility
Wire diameter ends up to 0.8 mm are squared and unground for durability
Wire diameter ends of 1.00 mm and above are squared and ground for enhanced stability
Manufactured with a right-hand helix for reliable performance
Made from high-quality steel alloy for superior strength
Can be directly mounted on rod products or inserted into tube products

When designing or selecting machinery springs, the following factors are critical:
Load Requirements: The spring must withstand the expected forces without permanent deformation.
Deflection: The spring should provide the required range of motion or compression.
Spring Rate (Stiffness): The force required to compress or extend the spring by a unit distance.
Fatigue Life: The spring must endure repeated cycles of loading and unloading without failure.
Environmental Conditions: Consider factors like temperature, corrosion, and exposure to chemicals.
Space Constraints: The spring must fit within the available space in the machinery.
Material Selection: Choose the appropriate material based on application requirements.
Coiling: The wire is coiled into the desired shape using CNC coiling machines.
Heat Treatment: Springs are heat-treated to enhance strength and durability.
Surface Finishing: Coatings or finishes (e.g., zinc plating, powder coating) are applied to prevent corrosion.
Testing and Quality Control: Springs undergo rigorous testing for load capacity, deflection, and fatigue life.
Machinery springs are often manufactured to meet industry standards, such as:
ISO 9001: Quality management systems.
ASTM International: Standards for material properties and testing.
DIN (Deutsches Institut für Normung): German standards for spring design and manufacturing.
Materials: High-carbon steel (ASTM A228), stainless steel (SUS 304), phosphor bronze, or Inconel for high-temperature applications.
Quality Check: Verify material certifications and perform chemical composition analysis.
Process: The wire is coiled into the desired shape using CNC coiling machines.
Precision: Tight tolerances are maintained for wire diameter, coil diameter, and pitch.
Tools: CNC spring coiling machines, mandrels, and guides.
Purpose: To relieve internal stresses and enhance durability.
Process: Springs are heated to 250-400°C for 30-60 minutes, followed by controlled cooling.
Result: Improved fatigue life and load-bearing capacity.
Purpose: To prevent corrosion and wear.
Processes:
Zinc Plating: Provides corrosion resistance (5-15 µm thickness).
Powder Coating: Adds a protective layer (50-100 µm thickness).
Shot Peening: Enhances fatigue resistance by inducing compressive stresses.
Testing: Salt spray tests (ASTM B117) to evaluate corrosion resistance.
