Functional Advantages

 

ULTIMATE WEAR RESISTANCE WITH CARBIDE CONSTRUCTION

Core die inserts are predominantly made of Micro-Grain Tungsten Carbide, offering unmatched hardness and resistance to abrasive wear and galling. This is critical for maintaining cavity dimensions and surface finish over millions of cycles when forming steel and stainless steel wires.

 

HIGH-PRESSURE ENDURANCE & FATIGUE STRENGTH

Engineered with robust support systems (e.g., Carbide Casings, Pre-Stressed Rings) to withstand immense radial and axial forces during the upsetting and extrusion processes. Premium materials and designs prevent cracking and premature fatigue failure.

 

PRECISION-MACHINED FOR COMPLEX GEOMETRIES

Utilizing advanced CNC grinding and EDM wire-cutting, we produce intricate die cavities and punch profiles for forming threads, undercuts, recesses (Phillips, hex), and complex head shapes with tight tolerances and excellent surface finish.

 

OPTIMIZED FOR HIGH-SPEED PRODUCTION

The design prioritizes efficient material flow, reduced friction, and rapid heat dissipation. This ensures stable performance at the high stroking speeds of modern Cold Heading Machines, maximizing output while minimizing downtime for tool changes.

COMPREHENSIVE TOOLING SYSTEM SOLUTIONS

We provide a complete set of matched tooling, including Heading Dies, Cut-Off Dies, Extrusion Punches, Pin Punches, and Push Point Punches. Our technical support covers die design optimization to maximize material utilization and part strength.

Core Applications

STANDARD & SPECIAL FASTENER MANUFACTURING
The core tooling for mass-producing a vast range of Hex Head Bolts, Socket Head Cap Screws, Machine Screws, Tapping Screws, and Nuts. Enables efficient, scrap-free production compared to machining.
 
AUTOMOTIVE & AEROSPACE FASTENERS

Employed beyond fasteners to produce intricate Cold-Headed Parts such as spark plug bodies, valve tappets, small shafts, and connectors used in automotive, electrical, and hydraulic systems.
 
ELECTRONICS & APPLIANCE COMPONENTS
Used to form precision pins, terminals, and other small metal components found in consumer electronics, household appliances, and electrical connectors, where high volume and consistent quality are essential.
 
INDUSTRIAL & CONSTRUCTION SUPPLY
Essential for producing a wide array of industrial-grade nails, rivets, pins, and other commodity metal parts demanded by the construction and general manufacturing sectors.

FAQ

Q1: Are you a manufacturer or a trade company?
A: We are a professional manufacturer of fastener mould with over 10 years of experience in this industry.
 
Q2: What is a cold forging die, and how does it function in the manufacturing process?
A: A cold forging die is a specialized tool used to shape metal at room temperature through high-pressure deformation. It functions by applying force to a metal blank, causing it to flow into the desired shape without heating the metal.
 
Q3: What materials are typically used to manufacture cold forging dies, and why?
A: Cold forging dies are typically made from high-grade tool steels like H13 or SKD61, or carbide. These materials are chosen for their exceptional hardness, wear resistance, and toughness, which allow them to withstand the intense pressures involved in cold forging.
 
Q4: What are the main advantages of using cold forging dies in production?
A: The main advantages include high-strength components, cost-effective mass production, superior surface finish, and reduced energy consumption compared to hot forging, making it environmentally friendly.

Q5: What advantage do you have?
A: We mainly have three capabilities:
1. Professional mould simulation development and design capability.
2. High-precision and high-stability mould manufacturing capability.
3. Optimization capability for continuous improvement of mould life.
