Durable Cold Heading Die for High Precision Metal Shaping
The key tooling used to form metal materials in the cold heading process is widely used in the manufacture of fasteners such as bolts, nuts, screws and other cold formed parts. Cold heading die is usually made of high hardness and wear-resistant material to withstand high intensity impact and pressure. In the process of cold heading, the die realizes the precision molding of the parts through cold extrusion or impact on the metal blank.
Description
Main Features
High abrasion resistance: Cold heading die has very high abrasion resistance, which can keep long-term stable working condition under high frequency and high intensity impact.
High strength and toughness: The mold material needs to have high strength and toughness in order to resist the strong impact and pressure during the cold heading process and prevent the mold from cracking or deformation.
Precision molding: The inner cavity and working surface of the mold are precision machined to ensure the dimensional accuracy and surface quality of the parts to meet the requirements of high-precision manufacturing.
Heat resistance: Cold heading die is able to withstand certain temperature changes, preventing the deterioration of the die performance caused by heat accumulation during the working process.
Easy to replace and maintain: The design of the mold takes into account the characteristics of easy to replace and maintain, reducing downtime and improving production efficiency.
Material Selection
Cemented carbide: Suitable for cold heading die with high strength and wear resistance requirements, especially for long-life, high-precision fastener production.
HSS: Suitable for medium to high strength cold heading operations, providing good wear resistance and thermal stability.
Die steel: Suitable for general cold heading die production, providing good toughness and wear resistance, widely used in various cold heading processes.
Applications
Cold heading dies are widely used in the following industries:
Fastener manufacturing: Used for the production of bolts, nuts, screws, rivets and other kinds of fasteners to ensure the precision and consistency of the products.
Automotive: In the cold forming process of automotive parts, such as bearings, transmission parts, etc., cold heading dies are used for precision forming.
Aerospace: Used to produce high-strength, lightweight aviation fasteners and structural parts, requiring molds with high precision and durability.
Electronic and electrical appliances: Used for the cold forming of electronic components, connectors and other small metal parts to ensure high precision and quality.
Home appliance manufacturing: In the manufacture of metal parts for home appliances, cold heading dies are used to form high-precision and high-strength structural parts.
