BLENDING METAL POWDER:
BLENDERS AND HANDLING COMPONENTS FOR YOUR PRODUCTION

Container Blender
for Mixing Metal Powder

Additive manufacturing, or 3D printing, is a fast-growing industry that is fundamentally different from traditional manufacturing processes. It offers new opportunities for research and development as well as for industrial manufacturing companies.

Advantages of 3D Printing:

Reduce manufacturing time
Reduce production costs
Reduced risk due to less expensive and shorter manufacturing process
Flexible customization of models
Design flexibility
Sustainability

Metal powder mixing and processing, as well as efficient powder handling for metal additive manufacturing, are becoming increasingly complex. At the same time, there is a need to achieve an effective and cost-efficient process, especially in metal powder mixing, material flow and increasing automation.

Perfect Metal Powder Blending Results

In the blending process, further alloying elements and the lubricant for the subsequent pressing process are mixed in addition to the metal powders. At the same time, the blending container is inerted.

The special feature in the handling of metal powders is that the material can easily oxidize due to its chemical properties and fine grain size with a correspondingly large surface area. This high reactivity means that the mixing of the metal powders takes place in an inert atmosphere.

In this case, a gas (argon or nitrogen) is added to the blend to prevent an explosive atmosphere. The result of the blending process is a metal powder with the desired material properties that minimizes frictional forces during pressing.

Overmixing should be avoided when mixing metal powders, as it increases the bulk density of the mixture. In addition, overmixing reduces the green strength of the compacts. This reduces the proportion of metal-to-metal contacts, crucial for green strength.

The flow properties are also affected. Good flow properties of the powder are elementary for filling the die.

Metal powder properties:

Further processing of the metal powder is affected by the following powder properties

Particle or grain size
Particle or particle size distribution
Particle or particle shape and structure
Surface texture

Bulk density is an important parameter because it has a significant effect on the strength of the compact that can be achieved during compaction.

A broad particle size distribution is advantageous to allow a powder to be easily and densely introduced into the die. The spaces between the larger particles are effectively filled by the smaller particles.

Smaller particle sizes result in smaller pores that close more easily during sintering. A higher proportion of fine particles degrades the flow properties of the powder.

The purity of the powder is critical. The level of acceptable contamination depends on which components are present and in what form.
