【Jewelry Vacuum  Casting Machine】

With the continuous development of modern industry, material science, and manufacturing technology are also constantly innovating. In the field of casting, vacuum pressure casting furnace has attracted widespread attention as a key technology. It achieves significant improvements in material properties and casting quality by applying vacuum and pressure during the casting process. This article will delve into the principles, advantages, and application fields of vacuum pressure casting furnaces, aiming to demonstrate the importance and potential of this technology.

1. Principle of Vacuum Pressure Casting Furnace

Vacuum pressure casting furnace is an advanced casting technology, whose core lies in controlling the atmosphere during the casting process to achieve a high vacuum environment and apply additional pressure. This process involves the following key steps

1.1 Vacuum treatment: Before the start of the casting process, the air inside the vacuum casting machine will be extracted to create a high vacuum environment. This can eliminate the presence of gases and impurities, thereby reducing the internal porosity of the casting and improving its density and uniformity

1.2 Pressurization operation: In a vacuum environment, pressure casting can be achieved by applying additional pressure to the molten metal. This pressure can eliminate bubbles inside the casting and promote a more uniform filling of the molten metal into the mold, thereby reducing shrinkage cavities and defects

CDOCAST Jewelry Vacuum Casting Machine is customized and made to melt and cast 1-6 kg of jewelry gold, silver, and other precious metals. Precious metal is melted and cast in an argon-protected atmosphere under a vacuum to protect your precious jewelry from oxidation, It achieves high density, high compactness, almost no air bubbles, and basically achieves non-shrinkage cavity casting.  Any precise jewelry and metal artwork can be perfectly done with the CDOCAST Jewelry Casting Machine. We also offer a year-round warranty and worldwide on-site training services.

Introduction

Water Atomizer/Vacuum Metal Powder Making Machine

The process of making metal powder by water atomization has a long history. In ancient times, people poured molten iron into water to make it explode into fine metal particles, which were used as raw materials for making steel; There are also people who pour molten lead water directly into the water to make lead pills. The process principle of making alloy powder by water atomization is the same as that of making water-burst metal liquid in ancient times, but modern technology has greatly improved the efficiency of crushing and manufacturing particles

To make metal alloy powder by high-pressure water atomization method, first, melt the raw metal in the melting furnace, and then the molten gold must be overheated for about 50 degrees and then injected into the tundish. Start the high-pressure water pump before the injection of metel solution, and let the high-pressure water atomization device start the workpiece. The metel liquid in the tundish enters the atomizer through the nozzle at the bottom of the tundish through the beam flow.

water atomizer

The atomizer is the key part for producing metal alloy powder by high-pressure water mist. The atomizer is related to the metal powder-making efficiency, Under the action of the high-pressure water from the atomizer, the molten metal liquid is continuously broken into fine droplets, which fall into the cooling liquid in the water tank and solidify into alloy powder。

In the traditional high-pressure water atomization process for producing metal powder, the metal powder can be collected continuously, but a small amount of metal powder is lost with the atomized water, In the process of producing alloy powder by high-pressure water atomization, the atomized product is concentrated in the atomization device, and then precipitated and filtered (it can be dried if necessary, and generally sent directly to the next process。

A complete set of equipment for producing metal alloy powder by high-pressure water atomization is composed of the following parts:

1:For the melting part, the medium frequency induction melting furnace is the best choice. The capacity of the furnace depends on the processing capacity of the metal powder, we have furnace capacity from 2kg to 100kg per batch.

2:  The atomization part, the equipment in this part is non-standard equipment, which should be designed and arranged according to the site conditions of the manufacturer, mainly including the tundish: when the tundish is produced in winter, it needs to be preheated;

Atomizer: the atomizer will come from high-pressure water, The high-pressure water of the pump impacts the metal liquid from the tundish at a predetermined speed and angle, breaking it into metal droplets.

Under the same water pump pressure, the amount of fine metal powder after atomization is related to the atomization efficiency of the atomizer; the atomization cylinder: it is the place where the alloy powder is atomized, crushed, cooled and collected.

3:In order to prevent the ultra-fine alloy powder from being lost with water, the obtained alloy powder should be left for a period of time after atomization, and then placed in the powder collecting box.

4:Post-processing part: powder collecting box: used to collect the atomized alloy powder and separate and remove excess water; drying furnace: dry the wet alloy powder with water;

screening machine: sieve the alloy powder, Out-of-specification coarser alloy powder can be re-melted and atomized as the return material

Feature

1: Adopt the electromagnetic induction heating principle with the feature of rapid melting time and  high production efficiency, The melting temperature rises quickly, the production efficiency is high, and the particle size distribution is good;

2: With the ability to 24-hour continuously work, can meet the needs of customers with different production output

3: Come with  vacuum Pump design, the whole granulation is carried out in the vacuum environment to minimize oxidation

Working Principles

Gas Atomization Vacuum Powder Making Machine Working Principles 

 

1. Melting Process: First The furnace should be vacuumed, and the raw materials in the crucible are induced to melt in a vacuum environment. After meeting the process requirements, the metal liquid is poured into the insulation crucible of the tundish, and flows into the atomization nozzle through the guide hole at the bottom of the insulation crucible;

2. Atomization Process: The atomization nozzle is filled with high-pressure inert gas, which accelerates through the Laval structure cavity to form a supersonic airflow. The metal liquid that falls into the atomization zone is impacted and broken, causing it to atomize into fine metal droplets;

3. Powder collection: Liquid droplets become spherical particles under surface tension in the air, rapidly cool and solidify into metal powder in the atomization chamber, and then collect the metal powder through a cyclone separation system

Feature

Gas Atomization Vacuum Powder  Making Machine Feature:

 

1. Strong applicability, capable of preparing most metals and their alloys that cannot be atomized with air or water. Typical products include stainless steel, mold steel, high-temperature alloys, cobalt chromium alloys, aluminum alloys, etc.

2. There are various incoming materials, including alloy ingredients, parent alloy, and powder return materials;

3. The cooling rate is fast, and the solidification rate of droplets reaches 103-106K/s, rapidly solidifying into fine microcrystalline structures;

4. High purity, refined alloy under vacuum, with gas and impurity content

5. Good powder quality, using tightly coupled or free atomization nozzle technology, with high sphericity and controllable particle size;

6. Easy to operate, short production preparation time, and capable of continuous batch production;

7: High controllability: Vacuum atomization equipment usually has multiple process parameters to adjust, such as liquid injection speed, pressure, temperature, etc., allowing the operator to accurately control the size, shape, and distribution of particles.
8: Stable powder quality: Due to atomization in a vacuum environment, the influence of impurities and oxygen in the gas on the powder can be reduced, thereby ensuring the quality and stability of the powder.

9: Avoiding oxidation reactions: Due to the low oxygen content in the vacuum environment, oxidation reactions of some substances can be avoided during the atomization process, thereby maintaining the chemical properties of the raw materials
