1. What Are Nails Made Of
The most common type of nails is made of low carbon steel wire (SAE 1006/1018). It is preferred for these reasons:
- Ductility – easy to process
- High strength after processing
- Low cost for mass production
- Suitable for galvanizing
Other Materials (Special Applications)
- Stainless Steel – Corrosion Resistance
- Copper – Decorative Applications
- Aluminum – Lightweight Applications
However, more than 90 percent of nails available in the market are made of steel nails using automated machines.
2. Nail Manufacturing Process (Step-by-Step)
Industrialized nail production follows a complete process:
- Wire Rod Preparation
- Wire Drawing
- Nail Forming
- Polishing & Surface Treatment
- Packaging
Let’s break down each step in detail.
Step 1 – Raw Materials
The metal nail manufacturing process usually uses 5.5mm or 6.5mm steel wire rod as raw material, and involves the following steps:
- Pickling (removing rust and oxide layers)
- Phosphating (improving lubricity)
Afterward, the wire smoothly enters the drawing process, improving the final wire quality and surface finish.
Step 2 – Wire Drawing Process (Critical Step)
The wire drawing process gradually reduces the wire diameter to the required nail size and lengthens the wire accordingly.
How It Works:
- The wire passes through a series of drawing dies.
- Each die gradually reduces the wire diameter.
- Lubrication prevents the wire from overheating, ensuring equipment and wire quality.
Example Parameters:
| Input Diameter | Output Diameter |
| 6.5 mm | 2.0–3.5 mm |
Why This Step Matters:
- Determines nail strength
- Controls surface quality
- Affects machine efficiency
Recommended Machine: RKM Straight Line Wire Drawing Machine
A modern straight-line wire drawing machine offers:
- High-speed drawing (up to 15 m/s)
- Automatic lubrication system
- PLC control for precision
- Continuous production
This is the first essential machine in a nail production line, Wire drawing is completed by a wire drawing machine, which reduces the diameter of steel wire to the required size.
Step 3 – Nail Forming Process (Core Production)
Here is an important process for turning iron wire into iron nails.
How Nail Making Machines Work:
The machine performs three actions in milliseconds:
- Wire feeding
- Cutting
- Head forming
This process is completed by an automatic nail making machine, which forms nails at high speed.
Production Speed:
- 300–800 nails per minute
- Up to 40,000 nails per hour
Key Features of Automatic Nail Making Machines
- Servo motor control
- High precision molds
- Adjustable nail length (1”–6”)
- Stable continuous operation
Output Capacity:
| Machine Type | Output (per day) |
| Small | 1–2 tons |
| Medium | 3-5 tons |
| Large | 6-10 tons |
Why Automation Matters
Compared to traditional machines:
| Type | Efficiency | Labor | Stability |
| Manual | Low | Medium | Moderate |
| Semi-atuo | Medium | Medium | Moderate |
| Automatic | High | Low | Excellent |
Fully automatic nail making machines dominate the market today.

Step 4 – Nail Pointing & Polishing
After forming, nails go through polishing.
Purpose:
- Remove burrs
- Improve surface finish
- Enhance appearance
Process:
- Nails placed in rotating drum
- Mixed with sawdust or polishing media
- Process runs for several hours
Step 5 – Surface Treatment (Galvanizing)
To prevent steel nails from rusting, galvanizing is also required.
Common Methods:
1. Electro Galvanizing
- Smooth finish
- Indoor applications
2. Hot-Dip Galvanizing
- Thick coating
- Outdoor / construction use
Why Galvanizing Matters
- Extends lifespan
- Prevents corrosion
- Improves product value
Step 6 – Packaging & Final Products
Finished nails are:
- Sorted by size
- Weighed automatically
- Packed into cartons or bags
Final Nail Types:
- Common nails
- Roofing nails
- Concrete nails
- Coil nails
3. How to Set Up an Automatic Nail Manufacturing Line?
Setting up a commercial wire nail production factory requires a well-structured equipment combination, adequate industrial infrastructure, and a clear understanding of production capacity. Below is the complete turnkey guide for establishing a modern, high-efficiency nail manufacturing plant.
1. Complete Equipment List for Nail Production Line
A standard automated wire nail production plant consists of four core machinery units working in sequence:
- 1. Wire Drawing Machine:
Reduces low carbon steel wire rod (typically SAE1008/Q195, 5.5mm) down to the target wire diameter required for nails (e.g., 2.0mm – 4.5mm). - 2. High-Speed Automatic Nail Making Machine:
The central unit that feeds the drawn wire, cuts it to exact length, forms the nail head, and punches the sharp diamond point continuously. - 3. Industrial Nail Polishing Machine:
A heavy-duty tumbling drum system using sawdust, oil, or paraffin to remove burrs, anti-rust oil, and surface impurities, giving nails a clean, shiny finish. - 4. Automatic Nail Packing & Weighing Line:
Automatically weighs, counts, and packages finished bulk nails into 20kg/25kg cartons or wooden boxes ready for shipping.
2. Essential Factory Infrastructure & Operating Requirements
To ensure smooth machine installation and continuous operation, your factory workshop must meet the following technical conditions:
| Factory Requirement | Technical Specification / Recommendation |
|---|---|
| Raw Material | Q195 / Q235 / SAE1006 / SAE1008 Low Carbon Steel Wire Rod (5.5mm coil) |
| Power Supply | 3-Phase Industrial Power (380V / 50Hz, customizable to local standards) |
| Required Workshop Area | 150 m² – 300 m² (including raw material coil storage and finished stock area) |
| Labor Requirements | 1 – 2 operators per shift (fully automated feeding and cutting process) |
3. Production Capacity & ROI Reference Guide
Selecting the right machinery configuration directly affects your daily output, energy consumption, and profit margin. Below is a standard operational reference for common automated nail production lines:
| Nail Range (Length) | Daily Output (8 Hours) | Total Installed Power | Operators Needed | Target Application |
|---|---|---|---|---|
| 1″ – 2″ (25 – 50mm) | 1.5 – 2.5 Tons | ~11 – 15 kW | 1 Worker | Roofing, Shoes, Small Craft |
| 2″ – 4″ (50 – 100mm) | 3.0 – 5.0 Tons | ~18.5 – 22 kW | 1 – 2 Workers | Building Framing, Wooden Pallets |
| 4″ – 6″ (100 – 150mm) | 5.0 – 8.0 Tons | ~30 – 37 kW | 2 Workers | Heavy Framing, Timber Construction |
