Screw Header Punches for Quality Manufacturing
In the manufacturing industry, particularly in the fastener sector, the importance of precision tooling cannot be overstated. One of the most essential components in the production of screws is the screw header punch. These tools play a critical role in shaping the heads of screws during the cold heading process, a method known for its efficiency, accuracy, and cost-effectiveness.
At Taiwan Metiz Alliance (TMA), we specialize in producing high-quality screw header punches that are designed to meet the exacting standards of modern manufacturing. With over two decades of experience and a commitment to innovation, TMA has become a trusted name in the tooling industry.
What Are Screw Header Punches?
Screw header punches are specialized tools used in cold-heading machines to form the heads of screws and other fasteners. These punches are responsible for creating the specific head shapes required for various applications, including flat heads, round heads, hexagonal heads, and specialty designs.
Cold heading, the process where these punches are employed, involves shaping metal at room temperature by applying high pressure. This process not only ensures material efficiency but also enhances the strength of the finished product due to work hardening. Screw header punches are essential for achieving the desired head dimensions and shapes with precision.

Cold Forming Trimming Dies and Cutting Dies: Essential Tools for Precision and Efficiency
In the world of cold forming, precision is paramount. The tooling used to shape, trim, and cut metal components plays a crucial role in ensuring the accuracy, functionality, and overall quality of the final product. Among the most important tools in cold forming operations are cold forming trimming dies or cutting dies. These dies are integral to the manufacturing of fasteners, automotive parts, and various other metal components that require precise cutting and trimming for optimal performance.
In this blog, we will explore the significance of cold forming trimming dies, their functions, and why investing in high-quality tools like those provided by Taiwan Metiz Alliance (TMA) is essential for achieving optimal results.
What are Cold Forming Trimming Dies?
Cold forming is a manufacturing process where metal is shaped at room temperature using high-pressure stamping or forging. Cold forming trimming dies are essential for removing excess material or flash from parts that are formed in a press or die. These dies are used at the end of the cold heading or cold forging process to "trim" the formed parts to their required shape, size, and finish.
Trimming dies are used for a variety of purposes, including:
- Flash Removal: Flash refers to excess material that flows beyond the die cavity during the forming process. Trimming dies help remove this excess material to ensure the part has clean, sharp edges and is within tolerance.
- Size Control: Trimming dies ensures that the parts are accurately sized, which is critical in applications where precise dimensions are necessary.
- Finishing: In some cases, trimming dies can also provide a smooth, burr-free surface finish on the part, improving both the aesthetic and functional qualities of the component.
Trimming dies (cutting dies) are commonly used in industries such as fastener manufacturing, automotive, aerospace, and electronics. These dies must be carefully engineered to accommodate the material properties of the parts being formed, as well as the type of forming process being used.

Tooling for Cold Heading and Thread Rolling Machines: The Backbone of Fastener Manufacturing
In the fast-paced world of manufacturing, precision and efficiency are paramount. Among the many industrial processes, cold heading and thread rolling are critical for producing high-quality fasteners like screws, bolts, and nuts. At Taiwan Metiz Alliance (TMA), we specialize in designing and producing tooling solutions that cater to these essential processes. With over 25 years of expertise and innovation, TMA has established itself as a trusted global partner for manufacturers seeking reliable, efficient, and high-performing tooling for cold-heading and thread-rolling machines.
Understanding Cold Heading and Thread Rolling
Cold heading is a process where metal wire or rods are shaped into fasteners without heating, utilizing high pressure and advanced dies. This method produces parts with exceptional strength due to the preservation of the material's grain structure. On the other hand, thread rolling involves forming threads onto fasteners by pressing them between hardened dies, ensuring consistent thread profiles with minimal material waste.
Both processes rely heavily on the quality of the tooling used. Accurate tooling not only enhances the product's durability and functionality but also optimizes manufacturing efficiency by reducing downtime and material costs.
