A Cold Heading Machine, also known as a Cold Former or Cold Forging Machine, is an advanced piece of industrial equipment that utilizes the principle of plastic deformation at room temperature. It forges metal wire into precise shapes-such as screws, bolts, nuts, pins, and various custom fasteners-through a series of dies and punches, without the need for heating the material. It is the cornerstone of modern, high-volume fastener production.
Core Principle: Instead of removing material through cutting, it applies tremendous compressive force to reshape metal wire within a die cavity, achieving chipless machining.
Exceptional Material Utilization
As a forming process, it generates little to no scrap, achieving material utilization rates of 95% to over 99%, significantly reducing raw material costs.
Extremely High Production Efficiency
Capable of producing dozens to hundreds of parts per minute through multi-station continuous operation, vastly outperforming traditional machining methods for mass production.
Superior Product Strength & Quality
The metal's grain flow is rearranged and follows the contour of the part, resulting in a denser structure, higher tensile strength, improved fatigue resistance, and a better surface finish compared to machined parts.
Excellent Dimensional Accuracy & Consistency
High-precision dies and a stable transmission system ensure that millions of parts are produced with tight tolerances and perfect interchangeability.
Fully Automated Operation
Integrated with automatic wire feeding, cutting, forming, and ejecting functions, it enables 24/7 unmanned production, reducing labor costs and intensity.
A typical cold heading machine consists of:
Wire Feeding Mechanism: Precisely advances the coiled wire into the machine.
Cutting Mechanism: Shears the wire into precise blanks.
Transfer Mechanism: Moves the blanks sequentially between different forming stations.
Punching System: Comprises the main slider, punches, and dies that perform the upsetting and forming operations.
Die System: The core tooling (main die and punches) that defines the final part shape, made from high-strength alloy tool steel.
Drive & Control System: Modern machines are powered by high-torque motors and controlled by a PLC and HMI Touch Screen for precise motion control and easy parameter setting.
Brief Workflow: Wire → Straightening → Feeding → Cutting → 1st Blow → 2nd Blow → Final Forming → Ejection.
Cold heading machines are categorized by the number of stations:
Single/Double Stroke Cold Headers: Ideal for simple, short parts or pre-forming.
Multi-Station Cold Headers (e.g., 3, 4, 5-station): The industry standard for complex parts. They integrate cutting, pre-forming, finishing, piercing, and threading into one continuous process.
Primary Applications:
Standard Fasteners: Screws, bolts, studs, nuts, washers.
Specialty Fasteners: Automotive wheel bolts, engine studs, high-strength structural components.
Complex & Non-Standard Parts: Hardware, electronic components, shafts, hollow rivets.
Material Range: Carbon steel, alloy steel, copper, aluminum, stainless steel, and more.
