Wire mesh is typically made from a variety of materials including stainless steel, galvanized steel, aluminum, brass, and bronze. It's used in many industries such as construction, agriculture, security, and industrial applications.
Here are some common types of customized wire mesh:
1. **Square Mesh**: The most common type with equal length and width wires.
2. **Rectangular Mesh**: Wider wires than the height wires.
3. **Diamond Mesh (Hexagonal)**: Wires form hexagonal shapes rather than squares.
4. **Twine Mesh**: Used for fencing and is formed by twisting wires together.
5. **Barrel Mesh**: Used in oil drilling for well casings.
6. **Window Mesh**: Designed for windows, often with smaller openings for better protection against intruders or pests.
7. **Security Mesh**: Often made from high tensile steel, it's used for enhanced security purposes.
Customization might also refer to the process of cutting the mesh into specific dimensions, adding coatings like PVC or Galvanizing for corrosion resistance, or incorporating features like perforations or openings of various sizes. The exact customization will depend on the intended use of the wire mesh.
Thread rolling: chipless production of threads
Thread production has been an essential part of human craftsmanship for thousands of years, with various manufacturing techniques evolving over time. While our passion lies in thread cutting, we believe it's important to share the benefits and characteristics of alternative methods like thread rolling. Each technique offers unique advantages depending on the application, material, and industry.
Today, let’s dive into **thread rolling**, a **chipless manufacturing process** also known as **thread forming**. Though the term “thread rolling†is more commonly used today, both terms refer to the same method. We’ll explore what makes this technique special, how it works, and whether it might be worth considering for your workshop or production line.
### What Makes Thread Rolling Unique?
The key difference between thread rolling and traditional thread cutting is that **no chips are produced** during the process. Instead of removing material, thread rolling uses **cold forming**—a process where the material is **deformed and shaped** without being cut. This means the **fibers within the material remain intact**, resulting in a stronger, more durable thread.
During rolling, the workpiece is pressed between two rotating rolls that have the desired thread profile engraved on their surface. As the rolls apply pressure, the material is displaced and formed into the correct shape. Because no material is removed, the **surface finish is typically better**, and the **mechanical properties of the material are preserved**.
### Different Thread Rolling Techniques
There are several methods for thread rolling, but the two most common are the **plunge method** and the **through-feed method**.
In the **plunge method**, the blank is placed between open rolling dies. The rolls rotate and press into the material, creating the thread profile in one pass. This method is ideal for short threads and offers **high precision** and **fast processing times**.
The **through-feed method**, on the other hand, involves feeding the blank through the rolling dies. These dies have three distinct sections: an **entry cone**, a **calibration area**, and an **exit cone**. This allows for the production of **longer threaded parts**, limited only by the length of the blank itself.
### Benefits of Thread Rolling
One of the main advantages of thread rolling is the **improved mechanical strength** of the finished product. Since the material isn’t cut, the **fibers are aligned and compacted**, which increases **wear resistance** and **fatigue life**.
Additionally, thread rolling is **faster** and **more efficient** than cutting, especially when producing large quantities. It also helps **reduce material waste**, as the blank can be smaller than the final component. Plus, since **no chips are generated**, there’s **less cleanup** and **fewer safety concerns** related to metal shavings.
### Challenges and Limitations
Despite its benefits, thread rolling isn’t suitable for every situation. For example, it **can’t produce internal threads**—it’s strictly used for **external threads**. Also, not all materials are ideal for rolling. The material must be **easily cold-formable** and have sufficient **elongation at break** (typically **12% or more**) to allow proper deformation.
Certain thread profiles, such as those with **vertical flanks**, are difficult or impossible to roll. However, **common fastener threads** like 60° or 55° threads work very well with this method.
### Is Thread Rolling Worth It?
If you're working on **small-scale projects** or occasional DIY tasks, **thread cutting with taps and dies** is likely the best option. The cost and space required for a thread rolling machine may not justify the investment unless you’re producing large volumes regularly.
However, if you're involved in **industrial production** or looking for **higher-quality, durable threads**, thread rolling could be a game-changer. For those who still need rolled threads, it’s often best to **consult a professional manufacturer**.
