Cemented Carbide Die

Introduction of Heading Die

The application in cold heading die area is one of the main applications of tungsten carbide material. Heading dies usually can be divided into punching die and bushing die, used in cold heading, warm heading, and hot heading technology situation. Toonney corrosion resistant metal plant applies high-quality corrosion resistant metal with good wear resistance. Toonney corrosion resistant metal plant is famous for its cold heading die and stamping die with a factory-price. Why can Toonney corrosion resistant metal plant offer a lower price for customers? Because Toonney corrosion resistant metal plant gets many supporting from previous customers and local government. Welcome to Toonney corrosion resistant metal plant for more information about stamping die and cold heading die.

Cold heading is a process technology which makes the workpiece transformation and the shape close to the finished product to the utmost extent in few processes. It is the footstone of modern machining and automobile industry. Toonney cold heading dies factory manufactures various heading die including drawing die, cold heading dies, precision dies,

carbide dies

, stamping die and forging die. Thanks to the government supporting police, Toonney cold heading die factory can offer really cheap cold heading die and stamping die.

Toonney stamping die manufacturer has gotten more and more popular at home and abroad. Because Toonney stamping die manufacturer has rich experience of producing stamping die. The design team of Toonney stamping die manufacturer is a really professional team with international level. As a famous local stamping die manufacturer, Toonney stamping die manufacturer gets some supporting from the government. So Toonney stamping die manufacturer can offer a good price also.

Under strong impact wear working conditions, tungsten carbide cold heading dies are required hard alloy has good impact toughness, fracture toughness, Fatigue strength, flexural strength, and good wear resistance.

1. Usually used in high cobalt and the coarse-grained alloy grades.
2. Carbide wear resistance, toughness relationship between the two are contradictory: to improve the wear resistance will lead to a decrease in toughness, and improve toughness and wear resistance inevitably lead reduction. Therefore, the choice of alloy grades, the need to work in accordance with the object and process conditions to meet specific requirements.
3. If the selected grades in use, prone to crack and damage early, should use a higher toughness grade; if the selected grade in use early wear and damage, should use high hardness, wear resistance and better grades. Toonney has below grades for stamping die options.
