Crucible Melting Ultrasonic Atomization Powder Making Machine: High-Quality Metal Powder Preparation Solution

The crucible melting ultrasonic atomization powder making machine developed by Sunway New Materials, a subsidiary of the Navigate Group, is an advanced metal powder preparation system integrating melting, ultrasonic atomization, powder collection, and classification. It is mainly suitable for the production of powders from metals and alloy materials with melting points below approximately 1300°C and high volatility, such as tin (Sn), zinc (Zn), magnesium (Mg), lead (Pb), aluminum (Al), and others. The equipment adopts ultrasonic atomization technology, which uses high-frequency vibration to break molten metal into micron-sized droplets and rapidly cool and solidify them in an inert gas protection environment, ultimately producing high-quality metal powders with high sphericity, high purity, and narrow particle size distribution.

I. Precision Ultrasonic Atomization for High-Quality Metal Powder Production
The equipment adopts a “crucible melting + ultrasonic atomization” process route. During production, the metal raw materials are first heated to a fully molten state in the melting system, after which the melt is delivered to the ultrasonic atomization nozzle at a stable flow rate.
Under the action of high-frequency ultrasonic vibration, a liquid film forms on the surface of the molten metal and is continuously broken into micron-sized droplets through ultrasonic cavitation effects and surface tension wave effects. When the vibration energy reaches the critical value of the liquid surface tension, the droplets detach from the vibrating surface to form uniform mist droplets, which are then rapidly cooled and solidified in a high-purity argon or nitrogen protection environment, ultimately forming high-quality metal powders.
The entire powder production process is continuous and stable with a high degree of automation, effectively ensuring powder particle size distribution and product consistency.

II. Four Core Advantages Empower Efficient and Stable Production

1.Superior Powder Quality
By adopting advanced ultrasonic atomization technology, the produced powder can achieve a sphericity of over 95%, with concentrated and uniform particle size distribution, excellent flowability, and powder spreading performance. Meanwhile, the fully enclosed inert gas protection environment effectively controls oxygen content, with oxygen increase as low as 50–150 ppm, making it especially suitable for the preparation of powders from active metal materials such as magnesium alloys.

2.Higher Production Efficiency
The powder yield of the equipment can exceed 95%, effectively reducing raw material loss. The automated control system enables coordinated operation throughout the entire process of melting, atomization, and collection, supporting long-term continuous and stable production while reducing manual intervention and improving production efficiency and batch consistency.

3.More Significant Energy Saving and Environmental Protection
Compared with traditional gas atomization processes, ultrasonic atomization does not require a high-pressure gas system. Vibration energy replaces part of the gas kinetic energy, reducing overall energy consumption by more than 90%. At the same time, the process adopts a purely physical atomization method with no wastewater discharge, and the inert gas can be recycled, providing both economic and environmental benefits.

4.Wider Material Adaptability
The equipment is suitable for the preparation of powders from aluminum, magnesium, copper, zinc, tin, lead, and various alloy materials. It also supports new alloy development and metal scrap recycling for powder production, meeting diversified needs for scientific research and industrial-scale production.

III. Multi-Industry Applications to Meet High-End Powder Manufacturing Demands
With excellent powder quality and stable process performance, the equipment is widely used in high-end fields such as metal additive manufacturing (3D printing), powder metallurgy, and new material research and development.
It is particularly suitable for volatile metals and alloy materials with melting points below approximately 1300°C that are prone to evaporation in plasma environments, such as Sn, Zn, Mg, Pb, and Al, providing reliable equipment support for the preparation of high-performance metal powders.
