Cold heading dies, also known as cold forging dies or cold forming dies, are specialized tools used in the cold heading process. Cold heading is a metalworking process in which a metal blank is formed into a desired shape using extreme pressure without heating the material. Cold heading dies play a crucial role in this process by shaping and forming the metal blanks into the desired final product.

The cold heading mold is used for cold heading, stamping, cutting, pre-forming, drawing of steel rods and steel pipes with high compression rate, upsetting, perforating, part marking on the blank material on the cold heading machine.

When it comes to screws, nuts, bolts, the cold heading mold is mainly used to forming the shape of the product’s rod, neck, and head, with the cooperation of a punch mold.

Screw heading mold is typically made of tool steel, or carbide, to ensure durability and precision.

And Donglong uses tungsten steel inside the mold, which makes it with high strength and long lifespan.

Donglong employs advanced machining techniques and technologies to ensure the accuracy and durability of the molds. CNC (Computer Numerical Control ) and ERP, are utilized to achieve intricate designs and tight tolerances required for various screw head shapes.

And Donglong’s QC department will check every stage of the production to reduce the rate of defective products.
