Tungsten carbide punches are hard alloy punches made mainly with tungsten carbide as the hard phase and combined with metal binders, and they have the following characteristics:

Material Properties

- High Hardness: Tungsten carbide itself has extremely high hardness, enabling the punches to easily handle various hard materials like stainless steel during the stamping process. They are less prone to wear and can maintain good dimensional accuracy and stamping shape.

- High Strength: They possess relatively high compressive strength and can withstand the huge pressure during stamping. They can still maintain good shape accuracy even after long-term use and are not easily deformed or damaged.

- Good Wear Resistance: During frequent stamping operations, the surface of the punches can resist the friction of materials, reducing wear and thus extending the service life of the punches, lowering the replacement frequency and improving production efficiency.

- High Temperature Stability: When heat is generated due to friction during the stamping process, they can still maintain stable performance and reduce the situation of punch damage caused by heat softening.

- Certain Toughness: Although they have high hardness, they still maintain a certain degree of toughness, so that when subjected to impact loads, they can better buffer stress and reduce the risk of punch breakage.

Manufacturing Process

- Powder Metallurgy Method: Tungsten carbide powder and metal binder powder are thoroughly mixed in a certain proportion, and then blanks are made through processes such as pressing and sintering. Subsequently, the blanks are processed into punches with specific shapes and sizes through precise machining and grinding processes.

Application Fields

- Hardware Stamping: Widely used in the stamping processing of various hardware parts, such as stamping nuts, bolts, washers, etc.

- Automobile Manufacturing: Used in the production of automobile parts, such as the stamping and forming of engine blocks, body structural parts, etc.

- Precision Electronics: In the production of precision electronic equipment, they are used to stamp tiny parts such as electronic components and connectors to ensure the accuracy and consistency of products.

- Pharmaceutical Industry: The pharmaceutical industry specifically selects them to make punches for stamping tablets because they have the characteristics of being resistant to acids and alkalis, not rusting, and having a long service life.

Product Advantages

- High Precision: With high dimensional accuracy, they can meet the requirements of high-precision stamping processing, ensure the consistency and reliability of products, and help improve product quality.

- Long Service Life: Due to their characteristics such as high hardness, wear resistance, and high strength, tungsten carbide punches have a long service life, reducing the downtime and costs caused by frequent punch replacements.

- Corrosion Resistance: They have excellent corrosion resistance and can maintain stable performance in humid, corrosive environments or when processing materials that are prone to corrosion, and are not easily rusted or corroded.
