Material
Shape
Surface Treatment:
  • Carbon Steel: Such as 65Mn and 70# steel, commonly used in general mechanical equipment due to their low cost and high strength. However, carbon steel offers relatively poor corrosion resistance.
  • Alloy Steel: Such as CrSi steel and CrV steel, known for their excellent strength and durability, making them ideal for high-load and high-frequency applications. These materials can also withstand higher temperatures to some extent.
  • Stainless Steel: Such as 304 and 316 stainless steel, known for their excellent corrosion resistance and durability, often used in humid or corrosive environments. 316 stainless steel is especially suitable for marine or chemical environments.
  • Copper Alloys: Such as phosphor bronze and beryllium copper, these materials offer good electrical conductivity and corrosion resistance, commonly used in electrical equipment or applications requiring conductivity.
  • Nickel-based Alloys: Such as Inconel, this material excels in high-temperature and corrosive environments, often used in extreme conditions like aerospace and chemical equipment.
  • Round Cross-section: This is the most common shape for hook extension springs, capable of withstanding a wide range of stress with good elasticity and resilience, suitable for most applications.
  • Square or Rectangular Cross-section: These shapes are typically used in applications requiring higher tensile strength, providing more force in limited space.
  • Conical Spring: Although less common, some hook extension springs are designed in a conical shape, allowing them to compress more tightly, ideal for applications with space constraints.
  • Different Hook Designs: The shape of the hooks can vary depending on the mounting method. Common types include:
    • Round Hooks: Suitable for standard assemblies and force applied from larger angles.
    • Straight Hooks: Ideal for precise installations, often used in narrow or confined spaces.
    • Half-round Hooks: Used in situations requiring smooth installation or specific force distribution.
  • Black Oxide (Oxidation Treatment): Forms an oxide layer that enhances corrosion resistance and wear resistance, commonly used in industrial environments.
  • Galvanizing: This process adds a zinc coating to improve corrosion resistance, particularly suitable for outdoor or humid environments.
  • Nickel Plating: Nickel plating improves both corrosion resistance and surface smoothness, while also enhancing appearance, making it ideal for applications where aesthetics are important.
  • Chrome Plating: Significantly increases surface hardness and corrosion resistance, suitable for high-strength, high-friction environments.
  • Spray or Coating Treatment: Used for color-coding springs or providing additional protection, often applied in specialized environments or custom applications.
  • Stress Relief Treatment: Heat treatment is applied to remove residual stresses from the manufacturing process, improving fatigue resistance and extending the spring’s lifespan, especially useful in high-frequency extension applications.

Highest Quality Stock Extension Spring and Custom Extension Spring Manufacturing

Your customers demand the highest quality springs for maximum load capacity and at Makeway Spring we have the springs you need. Our commitment to the highest quality spring for your application starts with the spring stock and doesn’t end until we pack and ship the last coil to complete your order.

Tension Spring Testing

We Rigorously Test and Measure Your Extension Springs to Meet Every Parameter You Require

Material Testing:
We monitor every lot of wire material that is submitted for testing and prototyping to ensure the highest quality product.

Dimensional Accuracy:
This involves measuring critical dimensions of the extension spring, such as wire diameter, outer diameter, length, and the number of active coils. This ensures that the spring conforms to your specified design requirements.

Load Testing:
This test involves subjecting the extension spring to various loads to verify that it can extend and retract without any deformation or failure. The load should be applied gradually to prevent sudden overloading

Elasticity and Stress Testing:
This test evaluates how well the spring returns to its original shape after being stretched. It measures factors like modulus of elasticity and yield strength to ensure the spring can handle the expected loads.

Fatigue Testing:
Extension springs are often subjected to repeated cycles of loading and unloading. Fatigue testing simulates these conditions to ensure the spring can withstand the anticipated number of cycles without failure

Load Testing:
This involves applying a load to the spring and measuring the corresponding deflection. This helps characterize the spring’s behavior under different loads.

Visual Inspection:
A visual examination of the spring is crucial to identify any surface defects, such as cracks, pitting, or other anomalies.

Tension Springs F.A.Q.

Tension springs store energy and resist pulling forces by elongating under load and returning to their original length. Typically made of stainless steel for durability and corrosion resistance, they’re vital in mechanical systems.

When selecting an extension spring with hooks, consider the following:

  • Tension requirements: Ensure the spring can handle the required load without deforming or failing.
  • Size and length: Choose a spring size that fits the installation space and displacement needs.
  • Material and surface treatment: Select appropriate materials and protective treatments based on the working environment, such as corrosion resistance or high strength requirements.

The tension an extension spring can handle depends on its material,wire diameter,number of coils,and design.Different specifications of extension springs are suited for various loads and applications.Manufacturers typically provide the maximum load specifications to ensure safe use.

The lifespan of an extension spring depends on factors such as usage frequency,applied tension,material,and environmental conditions.High-quality materials and proper surface treatments can extend the life of the spring.

Yes,if made from stainless steel or treated for corrosion resistance (e.g.,galvanized or coated),extension springs with hooks are suitable for outdoor or humid environments and can maintain performance for long period

End treatment plays a crucial role in the functionality and durability of extension springs.Common methods include closed and ground ends,open ends with hooks or loops,or other specialized configurations.Proper finishing,such as shot peening or coating,can enhance corrosion resistance and surface quality.

Quality control is paramount in extension spring manufacturing.This includes dimensional inspections,load testing,stress and elasticity testing,material analysis,and visual inspections.Additionally, following relevant industry standards and adhering to specific customer requirements is crucial for producing reliable and consistent springs.

Die springs are designed for high-load applications, commonly used in stamping dies and die sets. These springs are usually made of high-strength alloy steel, providing greater resistance to compression and longer service life.

Tension Springs

Tension springs store energy when stretched and return to their original shape when released. They are commonly used in applications such as door locks, toys, and mechanical devices. Tension springs typically have hooks on both ends for attachment.

Tension Springs(Headless)

Headless tension springs are similar to regular tension springs but lack traditional hooks or ends. These springs are used in applications requiring specific attachment methods to meet design requirements.
