Precision-crafted. Performance-assured. At Accurate, our helical springs are manufactured using cutting-edge CNC technology, robust quality systems, and decades of spring-making expertise.
Step 1
Material Selection

We begin by selecting high-grade wires suited to load, temperature, and corrosion requirements. Materials used:

  • Carbon Steel, Stainless Steel
  • Alloy Steel, Music Wire
  • Inconel & other specialty alloys Wire range: 0.08 mm to 14 mm Materials
Step 2
CNC Coiling

Springs are formed on CNC coiling machines with:

  • Micron-level precision
  • Auto-correction for pitch, length & OD
  • Flexibility for prototypes & bulk runs
Step 3
End Grinding (If required)

For compression springs, flat ends are ground to ensure:

  • Uniform load distribution
  • Stability in assembled position
Step 4
Heat Treatment

Springs are stress-relieved in automated furnaces to:

  • Enhance strength & dimensional stability
  • Eliminate internal stress post-coiling
Step 5
Shot Peening (Optional but recommended)

Improves fatigue life by:

  • Inducing surface compressive stress
  • Boosting resistance to cracking & wear
Step 6
Surface Finishing & Coating

Depending on application, we apply:

  • Electroplating (Zinc/Nickel)
  • Passivation,PTFE/Epoxy coating
  • Powder coating or Deburring/Cleaning
Step 7
Quality Control

Every batch undergoes strict testing:

  • Dimensional checks
  • Load & deflection tests
  • Life-cycle fatigue & hardness tests Follows ISO 9001 and IST UK protocols.
Step 8
Packaging & Delivery

Springs are securely packed to prevent damage.

  • Custom packaging available as per client needs

Reliable from Coil to Carton

With tight control over every step, Accurate ensures each spring performs flawlessly — from the production floor to your final product.

Spring Assembly Line Capabilities

In addition to standalone spring manufacturing, we have a dedicated spring assembly line to deliver fully integrated mechanical assemblies. Our capabilities include:

Welding Operations:

MIG, TIG, Spot, and Resistance welding to join springs with metal parts or structural components

Laser Cutting:

High-precision CNC laser cutting for brackets, retainers, and fixtures used in spring assemblies

Group Assembly & Fitment:

Skilled technicians handle sub-assemblies and final assemblies including fixtures, spacers, dampers, and hardware to create ready-to-install spring modules

Custom Tooling & Fixtures:

Designed in-house to ensure consistent and repeatable assembly quality

Inspection & Testing:

Each assembly is functionally tested for dimensional accuracy, fit, and mechanical integrity

This capability allows us to deliver pre-assembled spring components, reducing your assembly time and improving supply chain efficiency. Surface Finishing in Springs – Purpose, Processes, and Applications Surface finishing plays a critical role in the performance, durability, and appearance of springs across various applications. Whether for corrosion resistance, fatigue life enhancement, aesthetic appeal, or functional performance, the right surface treatment ensures that springs meet environmental and mechanical demands.
