How do you measure the density of solid powders in powder metallurgy? When it comes to determining the density of powder metallurgy materials, choosing a practical and user-friendly density meter is key. Once the right instrument is selected, measuring the density of these materials becomes straightforward and efficient.
The density of solid powder products typically involves measuring the density of semi-finished pressed parts, finished refined products, and MIM (metal injection molding) components. The DA-300M powder metallurgy densitometer is widely used across various types of powder metallurgy products. Depending on the type of material, different measurement modes can be chosen for accurate results.
Non-absorbent Product Measurement Steps:
- Place the product on the measuring platform and weigh it in air. Press ENTER to save the value.
- Submerge the product in water and measure its weight in water. Press ENTER again to display the density result.
Absorbent or Porous Material Measurement Procedure:
- Place the product on the measuring platform and weigh it in air. Press ENTER to store the value.
- After waterproof treatment, place the product back on the platform and weigh it again in air. Press ENTER to save this value.
- Submerge the treated product in water and measure its weight in water. Press ENTER to get the final density reading.
Measurement Theory of the DA-300M Powder Metallurgy Densitometer:
Powder metallurgy is a manufacturing process where metal powders, alloys, oxides, carbides, or similar materials are compacted under high pressure and then sintered or processed further to produce the desired material or component. This technique allows for the creation of complex shapes without traditional machining, by refining and shaping metal particles. Since the porosity of these materials significantly affects their physical properties, accurate density measurement is crucial for both the green body and sintered components.
The DA-300M densitometer uses the Archimedes principle and offers multiple measurement methods based on the material characteristics. These include the standard solid method, boiling saturation, immersion saturation, vacuum saturation, surface wax coating, and Vaseline coating techniques. With its versatility, the DA-300M can handle a wide range of powder metallurgy products, reducing time and labor costs while improving production efficiency and overall cost-effectiveness.
