How to Improve the Compaction Density of Metallurgical Products

In powder metallurgy, achieving high compaction density is a key step to ensure strength, durability, and performance of the final products. Low density leads to excessive porosity, weak mechanical properties, and reduced service life. Many manufacturers are seeking effective ways to enhance density, and one of the proven solutions is the use of specialized wax additives.

Wax additives, including wax emulsions, wax dispersions, and wax micropowders, play a crucial role in improving powder flowability and reducing friction during compaction. When powders fill the die cavity, poor flowability often causes uneven distribution and low density. By introducing wax emulsion or dispersion, the powder particles gain better lubrication and uniform filling, which results in higher green density.

During pressing, internal wax lubricants reduce inter-particle friction as well as friction between the powder and die wall. This ensures tighter compaction, minimizes cracks upon ejection, and protects the die from wear. Compared with traditional lubricants, modern wax additives provide more stable performance and can be adjusted to meet different pressure and temperature requirements.

In addition, wax micropowders can act as effective binders in powder metallurgy. They help particles adhere more closely during compaction, enhancing density and reducing defects. After sintering, the improved density translates into stronger metallurgical products with better wear resistance and longer service life.

For manufacturers in automotive, aerospace, machinery, and engineering industries, higher compaction density is directly linked to product reliability. By using our advanced wax emulsions, dispersions, and micropowders, you can achieve:
