Spring Manufacturing Process Tolerances
Process Stage | Key Control Parameter | Precision Grade & Typical Tolerance Reference | Control Points / Equipment Requirements |
1. Raw Material | Wire Diameter (d) | Commercial Grade: ±0.01 mm | Material certificate verification, batch management |
| Surface Quality | Free of cracks, rust, scratches | Visual inspection, surface defect detection (if necessary) |
2. Coiling/Forming | Outside Diameter (D)/Inside Diameter | Commercial: ±(0.01×D) mm or ±0.5% | CNC spring coiling machine accuracy, feed stability, tooling wear management |
| Total Coils (n1) | Commercial: ±1/4 coil | CNC program control, servo motor accuracy |
| Pitch | Uniform, conforming to drawing | Cam or servo axis control of coiler |
3. Heat Treatment | Hardness (HRC/HV) | As per material spec, e.g., ±2 HRC | Precise control of temperature, time, furnace atmosphere (Controlled atmosphere/Vacuum furnace) |
| Surface Decarburization | Commercial: Slight allowed | Strict control of furnace atmosphere carbon potential |
4. End Finishing | Grinding Angle (Squareness) | Commercial: ≤2° | Grinding wheel flatness, fixture accuracy, grinding parameters |
| End Thickness | ≥ 0.3d (to prevent end gap) | Control grinding amount |
| Bearing Plane Flatness | Contact area > 80% |
|
5. Surface Treatment | Plating/Coating Thickness | As per standard, e.g., 5-15μm ±3μm | Control of plating current, time, solution concentration |
| Hydrogen Embrittlement Risk | Hydrogen embrittlement relief mandatory | Strict control of baking temperature and time |
6. Stabilization | Free Height (H0) Stability | Height change after setting < 1% (Precision) | Press accuracy, control of compression stroke and cycles |
| Load Loss | Initial load loss < 5% (Precision) |
|
7. Final Inspection | Free Height (H0) | Commercial: ±(2%H0) mm | 100% inspection or AQL sampling |
| Load (P) @ Specified Height | This is the most critical functional indicator | Spring tester requires regular calibration, accuracy higher than tolerance requirement |
| Straightness/Squareness | Commercial: ≤1.5%H0 |

Surface Finishing for Custom Spring Manufacturing
Our surface finishing allows you to customize the appearance and texture of your milling parts. Various textures, colors, and finishes are available to match the aesthetic requirements of your product or brand.
| Category | Description | Material | Color | Texture |
|---|---|---|---|---|
Anodizing
|
Anodizing is an electrochemical process used to enhance the corrosion resistance, appearance, and surface properties of metal parts, particularly aluminum. | Aluminum, Metals | Clear, black, grey, red, blue, gold | Rough, smooth, metallic |
Powder Coating
|
Powder coating is a popular and environmentally friendly method of applying a protective and decorative finish to various types of metal and even some non-metal surfaces. | Metals | White, Black, RAL and Pantone | Glossy, fine, hardness |
Polishing
|
The primary goal of polishing is to create a smooth and reflective surface by removing imperfections, scratches, and irregularities. | Metals | Silver gray | Bright, mirror, silk |
Chromate
|
Chromate, commonly known as a chemical thin film, is a conversion coating used as a corrosion inhibitor on aluminum. | Aluminum | Clear/ Slight yellow tint | Satin |
Bead blasting
|
Bead blasting, also known as abrasive blasting, is a surface preparation technique used to clean, finish, or texture a surface by forcibly propelling small, spherical abrasive materials, called "beads" or "media," at high speeds onto the surface being treated. | Aluminum, copper, stainless steel, steel | N/A | Grainy, slightly matte texture |
As machining
|
Machining is a subtractive manufacturing process in which a machine tool, typically a cutting tool, removes material from a workpiece to achieve the desired shape, dimensions, and surface finish. | Metals | N/A | Smooth, glossy finish |
