High-Performance Carbide Piercing & Extrusion Punches for Cold Heading
FMT China is a premier manufacturer of high-precision tungsten carbide pins and high-speed steel (HSS) tooling. We specialize in providing durable solutions for hole punching pins for cold heading and piercing pins for metal forming. Our components are engineered to withstand extreme pressure, ensuring longevity and precision in high-volume production environments.
Specialized Punch Pins for Blanking and Metal Forming
Our range of punch pins is designed to meet the rigorous demands of modern screw and fastener manufacturing. Whether you need replacement piercing punches for Sala punzoni or custom metal extrusion punch tools, we offer the following:
- Ejection Pins (Kick-out Pins): Essential for seamless part removal, preventing jamming and ensuring high-speed production cycles.
- Extrusion Pins: Also known as forming pins or mandrels, these are critical for defining the internal geometry and thread profiles of your fasteners.
- Piercing Pins: High-hardness tools designed to create precise initial indentations in metal blanks.
The Precision Extrusion Process in Screw Manufacturing
The performance of your metal extrusion punch tools directly impacts the thread quality. Here is how our high-precision pins integrate into your production line:
- Material Feed: Raw metal wire is prepared for high-pressure forming.
- The Extrusion Phase: Through a combination of heat and compression, the material is forced through a die.
- Mandrel Insertion: Our extrusion pin acts as a mandrel, positioned in the center of the die to shape the internal thread.
- Cooling & Hardening: The screw solidifies around the pin, ensuring structural integrity and dimensional accuracy.
- Pin Removal: Once hardened, the pin is retracted, leaving a perfectly formed internal thread.
By using FMT’s carbide punches, you reduce friction and thermal wear, leading to fewer tool changes and lower cost-per-part.
Advanced Piercing Pins for Metal Forming
For hole punching pins for cold heading, durability is non-negotiable. We provide various configurations to suit your specific material hardness:
- Solid & Tapered Pins: Ideal for precise, gradual penetration into screw blanks.
- Hollow Piercing Pins: Optimized for chip evacuation to prevent debris buildup.
- Tungsten Carbide-Tipped Pins: The ultimate choice for high-volume production, offering maximum resistance to wear and deformation.
- Custom Tooling: We manufacture punch pins for blanking tailored to your unique drawings and material specifications.
