Features of Factory Whole Tungsten Steel Powder Metallurgy Mold YG20 Carbide Sealing Ring Molding Mechanical Sealing Ring Molding
Physical Characteristics
Particle Size: Ranging from nanometers to hundreds of micrometers, the size distribution significantly influences the powder’s flowability, packing density, and sintering behavior.
Shape: Particles can be spherical, irregular, flake-like, or dendritic, each shape affecting the final product’s mechanical properties and surface finish.
Purity: Depending on the production method, metal powders can achieve high levels of purity, critical for applications like electronics and aerospace where impurities can degrade performance.
Density: While less dense than their solid counterparts due to the presence of air between particles, metal powders can be densely packed during processing to approach the density of the solid metal.
Chemical Properties
Reactivity: Some metal powders, particularly aluminum and titanium, are highly reactive with air and moisture, necessitating careful handling and storage under inert atmospheres or vacuum.
Oxidation: Exposure to air can lead to surface oxidation, forming a passive layer that affects sintering and other processes. This can be managed through surface treatment or use of protective atmospheres.

Title: Factory Specifications for High-Quality Tungsten Steel Powder Metallurgy YG20 Carbide Sealing Ring Molding – Advanced Mechanical Seal Ring Molding Parameters
Introduction:
This detailed overview highlights the manufacturing parameters for our state-of-the-art factory-produced tungsten steel powder metallurgy (PMM) moldings, specifically designed for YG20 carbide sealing rings. These sealing rings play a vital role in various mechanical applications due to their exceptional wear resistance and durability.
Material Composition:
The heart of these seals is made from YG20 carbide, a renowned material known for its high hardness, wear resistance, and thermal stability. YG20 consists of tungsten carbide particles dispersed in a cobalt binder, providing an ideal combination of strength, toughness, and heat resistance for demanding sealing environments.
Molding Process:
Our PMM process begins with the selection of high-quality tungsten carbide powder, which undergoes meticulous sieving and blending to ensure uniform particle size distribution. The powder is then compacted under high pressure into a pre-designed mold, where it consolidates through sintering at elevated temperatures. This process allows for the formation of a dense, homogeneous structure without voids or porosity.
Molding Parameters:
1. Particle Size Distribution: The YG20 carbide powder has a controlled particle size range, typically between 30-50 microns, to ensure optimal bonding during sintering and the formation of a strong, dense seal.
2. Compaction Pressure: A critical factor, the compaction pressure ranges from 600 to 900 MPa, ensuring the particles interlock effectively, creating a robust and dense structure.
3. Sintering Temperature: The YG20 powder is sintered at temperatures between 1250-1450°C, allowing for the diffusion of cobalt binder and the elimination of any remaining pores.
4. Holding Time: The sintering process is followed by a controlled holding time to ensure complete densification and bond formation, usually ranging from 2 to 4 hours.
5. Cooling Rate: Post-sintering, the ring is rapidly cooled to room temperature, preventing any distortion or cracking, and maintaining the desired microstructure.
6. Finish Treatment: The mold is subjected to precision grinding and polishing to achieve a smooth surface finish, critical for sealing performance and longevity.
7. Quality Control: Rigorous quality checks are performed at every stage, ensuring adherence to industry standards and meeting the high-performance requirements of the YG20 carbide sealing rings.
In conclusion, our factory specializes in manufacturing tungsten steel PMM YG20 carbide sealing rings with precision molding parameters. These seals offer outstanding sealing capabilities, resistance to wear, and extended service life, making them indispensable in various industrial applications. Our commitment to quality and attention to detail ensures that each mold delivers reliable performance in even the harshest conditions.
