Advanced atomization powder-making equipment
We specialize in the R&D and manufacturing of complete powder‑processing systems, offering efficient and reliable solutions for metal powder production.
VIGA’s vacuum induction gas atomization powder‑making equipment boasts a broad range of applications, enabling the production of alloy powders based on iron, nickel, cobalt, aluminum, copper, and more. It is widely employed in advanced manufacturing fields such as 3D printing, fused deposition modeling, laser cladding, thermal spraying, powder metallurgy, and hot isostatic pressing.
Process Principle
- Melting: The furnace is evacuated, and the charge in the crucible is melted by induction heating under vacuum. Once the process requirements are met, the molten metal is poured into an intermediate holding crucible and flows through a bottom guide port into the atomization nozzle.
- Atomization: A high-pressure inert gas is introduced into the atomizing nozzle and accelerated through a Laval‑type convergent–divergent nozzle, generating a supersonic gas stream that impacts and breaks up the molten metal entering the atomization zone, thereby atomizing it into fine metal droplets.
- Powder collection: Droplets in the air, governed by surface tension, assume a spherical shape; within the atomization chamber, they rapidly cool and solidify into metal powders, which are then collected by a cyclone separation system.
Craftsmanship Features
- It boasts broad applicability and can be used to produce metal powders of various alloy systems; typical products include stainless steel, tool steel, high‑temperature alloys, cobalt‑chromium alloys, aluminum alloys, and more.
- The charge materials are diverse, allowing for the selection of alloying additives, master alloys, and recycled powder.
- The cooling rate is high, with droplet cooling and solidification rates reaching 10³ to 10⁶ K/s, resulting in rapid solidification that yields a fine, equiaxed microstructure.
- High purity; alloy refined under vacuum, with low levels of gas and impurities.
- The powder boasts excellent quality, employing either a tightly coupled or free‑flow atomization nozzle technology, resulting in high sphericity and controllable particle size.
- It is easy to operate, requires short production preparation time, and enables continuous batch production.
Electrode‑induction gas atomization equipment is a highly efficient metal powder production system, widely used in the aerospace, automotive manufacturing, and advanced electronic materials industries. Leveraging cutting‑edge electrode‑induction melting and inert‑gas atomization technologies, this system enables precise control of the melting process, yielding high‑purity metal powders with low oxygen content, uniform particle size distribution, and excellent sphericity—making it an ideal choice for producing high‑performance metal powders.
Process Principle
The fundamental principle of the EIGA gas atomization powder‑making process is to inject a stream of molten metal through a high‑pressure nozzle, forming fine droplets. Upon instantaneous impact, these droplets rapidly solidify into solid powder particles due to surface tension. During gas atomization, the combined effects of impact and surface tension result in a relatively narrow particle size distribution and uniform particle dimensions.
Craftsmanship Features
- By integrating aerosolization technology with electrode induction melting, and eliminating components such as crucibles that come into direct contact with the molten metal, impurity contamination during the melting process can be effectively minimized, enabling the safe and clean melting of reactive metals.
- During inert high-pressure gas atomization, the molten droplets undergo rapid solidification at rates of 10³–10⁶ K/s, resulting in a uniform microstructure with no macrosegregation or microsegregation.
- Effective control of key technical parameters such as powder particle size distribution, sphericity, and oxygen enrichment is achieved through technological optimization.
- A two-stage cyclone classification collection system is employed to enhance powder recovery and minimize or eliminate the emission of fine particulate matter.
Plasma Rotating Electrode Atomization (PREP) equipment is a metal powder‑production system based on the PREP technology. It operates by using the centrifugal force generated from the high‑speed rotation of an electrode to fling molten metal into fine droplets, which then solidify in an inert atmosphere to form spherical powders. This equipment is primarily used to produce high‑quality spherical metal powders, such as titanium alloys, superalloys, and stainless steels. The resulting powders exhibit excellent sphericity, low levels of hollow particles, and high purity, making them widely applicable in additive manufacturing, powder metallurgy, laser cladding, and other fields.
Process Principle
Plasma Rotating Electrode Atomization (PREP) equipment is a metal powder‑production system based on the PREP technology. Its core operating principle involves, under an inert‑atmosphere environment, using a plasma to melt the tip of a rapidly rotating electrode rod. The centrifugal force generated by the electrode’s high‑speed rotation flings off the molten metal film, breaking it into fine droplets; these droplets then cool and solidify in the inert atmosphere, forming spherical powder particles. The equipment typically comprises a rotating electrode rod, a plasma generator (or plasma torch), an atomization chamber, a heating source, an electric motor‑driven rotary mechanism, a vacuum system, a cooling system, and a gas‑circulation system.
Craftsmanship Features
- The operating speed has been significantly increased, and the fine‑powder recovery rate is high (exceeding 80% for superalloy fine powder).
- The powder exhibits a sphericity of over 95%, with virtually no hollow particles or satellite particles.
- The process is carried out in an inert atmosphere of either argon or helium, making it particularly well suited for the development of alloy powders such as Ti, Ni, Co, stainless steel, and refractory metals.
- Non-contact milling throughout the entire process ensures high powder purity and low impurity levels.
- It requires only a footprint of 4 m × 3 m, and installation is straightforward.
- A concise and professional user interface design, with real-time recording of process test data.
