I. Revealing the Common “Symptoms” of Tungsten Carbide Die Faults

1. Wear Faults: The “Scars” Left by Time

During prolonged contact and friction with workpieces, the surface of tungsten carbide die gradually shows signs of wear, just like a blade being constantly polished. This wear may not be obvious at first, but as the usage time increases, it will become more severe. When the wear reaches a certain level, the dimensional accuracy and shape accuracy of the die will deviate like a train off the tracks, resulting in non-compliant products and a significant drop in production efficiency.

2. Crack Faults: The “Crisis” Hidden Beneath the Surface

When tungsten carbide die is subjected to significant impact forces or experiences drastic temperature changes, its internal structure may crack like a torn piece of cloth. These cracks are like “time bombs” in the die. They not only reduce the die’s strength and wear resistance, making it more susceptible to further damage, but may also trigger serious safety accidents during production, causing huge losses to enterprises and employees.

3. Deformation Faults: The “Distortion” under High Temperature and Pressure

In harsh environments of high temperature or high pressure, tungsten carbide die is likely to deform, just like a piece of clay exposed to the scorching sun. After deformation, the dimensional accuracy and shape accuracy of the die are difficult to guarantee, like a distorted painting, and cannot meet the strict requirements of product production, resulting in waste products.

4. Corrosion Faults: The “Erosion” by Chemical Substances

During use, tungsten carbide die may come into contact with various chemical substances, which act like invisible “killers” and erode the die’s surface, causing rust or pitting. Corrosion not only damages the die’s appearance but also reduces its strength and wear resistance, shortening its service life and increasing production costs for enterprises.

The material properties of tungsten carbide die are like a person’s physical fitness, directly affecting its service life and fault occurrence rate. If the material selection is inappropriate or the material itself has quality issues, it is like planting a “time bomb” in the die. During use, the die is prone to various faults and cannot perform to its full potential.

2. Design Factors: The “Root Causes” of Structural Defects

The design of the die is like the blueprint of a building. If the design is unreasonable or the structure is overly complex, it will lead to various problems during the manufacturing and use of the die. For example, uneven wall thickness of the die is like an unbalanced bridge, prone to problems under pressure; a too-small fillet radius creates a weak point at the stress concentration area of the die, making it prone to cracks or deformation.

3. Manufacturing Process Factors: The “Flaws” in the Production Process

The manufacturing process has a crucial impact on the performance and quality of the tungsten carbide die. If there are process defects or improper operations during manufacturing, it is like a fine porcelain piece having flaws during firing, which will lead to quality issues in the die and affect its service life.

4. Use and Maintenance Factors: The “Neglect” in Postnatal Care

During use, if the operators handle the die improperly or fail to maintain it in a timely manner, it is like a person neglecting their health, overworking without proper care, which will lead to faults in the die. For example, excessive impact forces, high temperatures, or poor lubrication during die use may all cause problems such as wear and cracks in the die.
