Specialized Machining of Tungsten Carbide Needles

1. Material Selection and Preparation

• Tungsten Carbide Properties: With a hardness of 85 to 95 HRA (equivalent to 68-81 HRC), tungsten carbide is exceptionally resistant to wear and corrosion. These properties make it ideal for creating punches that demand longevity and resistance to harsh conditions.
• Material Certification: We ensure that all materials used are of the highest quality and provide material certifications to verify compliance with industry standards.

2. Ultra-Precision Machining Techniques

• Micro-Diameter Machining: The ability to machine tungsten carbide rods down to a diameter of 0.02mm requires advanced technology and precision engineering. This process involves specialized machinery capable of maintaining extreme accuracy.
• Grinding Process: The punches can be ground to specific angles ranging from 10° to 90°. This flexibility allows for customization according to the specific needs of the application, whether it’s for hardware stamping molds or other high-precision components.
• End Processing: The ends of the punches can be ground to achieve different profiles, including flat, chamfered, or various other shapes to meet complex design requirements.

3. Dimensional Accuracy and Surface Finish

• Flatness and Shape Precision: We guarantee a flatness of 0.02mm at the tip of the punches, which is critical for ensuring the accuracy and functionality of the component in its application.
• Surface Treatments: Depending on the requirements, punches can undergo additional surface treatments to enhance their performance characteristics, such as improving lubricity or increasing resistance to environmental factors.

4. Quality Control and Customization

• Inspection and Testing: Each batch of needles undergoes stringent quality control procedures, including dimensional verification and material property testing, to ensure that they meet the precise specifications and high standards expected by our clients.
• Customization and Client Collaboration: We work closely with our clients to understand their specific needs and provide tailored solutions, from the initial design phase to the final delivery of the product.

Applications of Tungsten Carbide Punches

The ultra-fine tungsten carbide punches machined to these exacting standards are essential in various high-tech industries, including electronics, medical devices, and precision engineering. Their ability to perform reliably in demanding environments makes them invaluable in applications such as:

• Micro-stamping components
• Intricate mold making
• Precision insertion tools
