Cold heading, also known as cold forming or cold extrusion, is a metalworking process that involves the shaping of metal wire or rod at room temperature using dies and punches. This process is commonly referred to as cold heading due to its ability to produce intricate shapes and forms without the need for high temperatures.
The Fasteners capacity of welle manufacturers including process, material, weight and size is listed as follows:
✧ Cold Heading Process: Forging, Cold Heading, Stamping, Heat treatment, Machining,Thread Rolling, Grinding, CCD Inspection, Mechanical Property testing, Material analysis, Salt spraying and Thickness testing, TEFLON/XYLAN Coatings and more.
✧ Cold Heading Material: Plastic, Titanium alloy, Super alloy Steel,Aluminum, 40Cr, 42CrMoA, 42CrMo4, 40CrNiMoA, 35CrMo, 35VB, SCM440, SCM435, B7, 20MnTiB, C45E, C35E, 10B21, 1008, 1010, Q235, Q345D, Alloy steel, Duplex Steel, Hastelloy, Inconel alloy, Monel 400, Silicon Bronze etc.
✧ Grade: Bolt Grade (8.8/9.8/10.9/12.9), Nut Grade (8/9/10/12),Customed based on customer requirement;
✧ Size: M3-M80
Bolt Diameter (M3-M25, M16-M56), Max. Bolt Length up to 12000mm;
Nut Diameter(M6-M24), Max Nut Length up to 65mm;
Process: In the cold heading process, a metal blank is placed into a die and struck by a punch. The force applied causes the material to flow into the die cavity, creating the desired shape. This is typically a high-speed, mass production process used for producing bolts, screws, rivets, and other fasteners.
Materials: Cold heading is suitable for various materials, including steel, aluminum, copper, and alloys. The choice of material depends on the specific requirements of the end product, such as strength, corrosion resistance, and conductivity.
Quality Requirements: Quality control in cold heading involves monitoring dimensional accuracy, surface finish, and material properties. Inspections may include checks for uniformity, absence of defects, and adherence to specified tolerances.
Applications: Cold heading is widely used in the manufacturing of fasteners and precision components for industries such as automotive, construction, electronics, and consumer goods. Common products include bolts, screws, rivets, and special cold-formed parts.
