Overview of Custom Manufacture OEM Production Metal Injection Molding MIM Tungsten Products
Tungsten is a metallic element with the element symbol W and atomic number 74. It is located in the VIB group of the sixth period of the periodic table of elements. In nature, tungsten mainly exists in the form of hexavalent cations. Its ionic radius is small, it has strong polarization ability, and it is easy to form complex anions.
When preparing pure tungsten or tungsten alloy, the main methods include powder metallurgy, smelting (including electron beam melting, vacuum melting, plasma beam melting) and chemical vapor deposition.
Feature of Custom Manufacture OEM Production Metal Injection Molding MIM Tungsten Products
The thermal expansion coefficient of tungsten is very low, only 4.5×10^-6 m/mK, so it has good thermal stability. These properties make tungsten widely used in manufacturing high-temperature components and reliable heat detectors.

Parameters of Custom Manufacture OEM Production Metal Injection Molding MIM Tungsten Products
Metal Injection Molding (MIM) is a process used to produce high-quality, precision metal components by injecting molten metal into a mold under high pressure. Tungsten, due to its high density, strength, and heat resistance, is a popular material for MIM applications. Here are some key parameters for custom manufacturing of Tungsten products using MIM:
1. **Material**: Tungsten alloy, typically containing elements like carbon, nickel, cobalt, or molybdenum, is used. The specific composition depends on the desired properties like hardness, wear resistance, and machinability.
2. **Density**: Tungsten has a very high density (19.3 g/cm³), which results in heavy and dense components that can be beneficial for certain industries like aerospace, defense, and industrial machinery.
3. **Melting Point**: Tungsten alloys have high melting points, usually around 3422°C (6200°F), ensuring the material withstands the intense temperatures during the molding process.
4. **Injection Temperature**: The process requires a temperature range of around 1650-1800°C (3000-3360°F) to melt the tungsten alloy.
5. **Mold Design**: The mold must be made of materials like refractory ceramics or tungsten carbide to handle the extreme temperatures and pressures. It’s critical for intricate geometries and tight tolerances.
6. **Pressure**: Injection pressure is typically high, around 10-20 MPa (1450-2900 psi), to ensure accurate filling of the mold cavities.
7. **Cycle Time**: Depending on part complexity, cycle times can range from minutes to hours. Faster cycles are possible with advanced machines and optimized processes.
8. **Post-Molding Treatment**: After injection, parts may undergo various treatments like sintering (to densify the material), machining, polishing, and heat treatment to achieve the desired final dimensions and surface finish.
9. **Surface Finish**: MIM Tungsten products can have a surface finish as good as Ra 0.1-0.5 microns, depending on the post-processing techniques.
10. **Strength and Hardness**: MIM Tungsten can exhibit high strength and hardness, making it suitable for load-bearing and wear-resistant applications.
11. **Weight Savings**: Due to the high density, MIM can offer significant weight savings compared to traditional manufacturing methods, especially for aerospace and automotive components.
These parameters will vary depending on the specific requirements of the product being manufactured, so it’s essential to work closely with a skilled MIM provider to optimize the process for your custom application.
