The carbide cold heading Main Single Sided Die With a Straight Hole

Cold heading dies include various types such as straight hole dies, triangular dies, extrusion dies, trimming dies, and socket dies. The method of cold pressing, shrink fitting, or taper fitting is chosen for the carbide inserts based on the specific application or customer requirements. Similarly, the carbide heading dies come in different variations such as plain hole, pointing, extrusion, trap extrusion, hexagonal, hex extrusion, flat extrusion, and trilobular to cater to the production of various types of fasteners, screws, and bolts.
The cold heading process involves forging at very high speeds where the coiled wire is carefully sheared to length at room temperature and the correct pressure. Then it is moved through continuous die and tool openings to displace and shape the working metal to form the required product. The cold heading process can decrease or increase feedstock diameters and lengths and can remove small amounts of material through piercing and trimming. All cold heading processes and operations are done in a continuous, planned process.
