Tungsten Carbide Alloy Punches for Precision Stamping
The carbide notch punches we process according to the customer's drawing requirements have slightly different dimensions and specifications compared to other alloy punches. Conventional carbide punches are mainly round punches and square punches. This series of notch punches mainly blanks through the inner hole. According to the terminology of mold processing operations, the notch is the cutting edge of the punch and the die. Mainly for the processing and use requirements of hardware and plastic operations, continuous, stable and good service life and accuracy guarantee are the basic requirements of this carbide notch punch.
High wear resistance and service life are the basic requirements for stamping products of precision stamping molds. Especially under the requirements of long-term collaborative operation of mechanical equipment such as progressive dies, combination dies, and multi-station dies, the excellent performance of tungsten carbide materials is a high-quality performance for long-lasting operations. As a tool material, tunsten carbide has become the preferred high-quality punch material for stamping dies due to its high hardness, high strength, and high wear resistance. According to the actual production operation requirements, the production and processing of carbide punch parts and accessories provide non-standard customization, based on the customer's specific drawing requirements.
Processing of Tungsten Carbide
The processing technology for tungsten carbide products varies depending on the type and intended use of the product. Here is a general processing workflow for tungsten carbide products:
- Raw Material Preparation: Select high-purity tungsten powder and carbon powder as raw materials.
- Material Mixing: Blend tungsten and carbon powders in specific proportions to ensure a uniform mixture.
- Pressing and Shaping: Place the mixture into molds and subject it to high pressure to achieve the desired shape.
- Initial Sintering: Place the pressed blank in a high-temperature furnace for initial sintering, forming a preliminary structure.
- Powder Metallurgy Sintering: Subject the preliminarily sintered blank to powder metallurgy sintering, allowing carbon to react fully with tungsten to produce tungsten carbide.
- Heat Treatment: Conduct heat treatment on the sintered product to adjust its crystal structure and properties, enhancing hardness and wear resistance.
- Mechanical Processing: Employ machining processes such as cutting, milling, and grinding on the heat-treated blank to achieve the final product shape.
- Surface Treatment: Optionally perform surface treatments, such as coating or polishing, to enhance surface properties as needed.
- Quality Inspection: Conduct quality checks on the finished tungsten carbide products to ensure they meet specified technical standards and customer requirements.
- Packaging and Delivery: After passing quality inspection, package the products and deliver them to customers.
It's important to note that different types of tungsten carbide products may have variations in this basic process, and specific processing techniques can also be influenced by product design requirements and intended applications.
