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

3. CDOCAST metal extruder adopts four guide rod structure, which makes the rigidity of the machine better and fully improves the balance of extrusion.
4. The die head of the machine adopts the front mode, and the extrusion die head is set between the front seat of the oil cylinder and the piston rod. Because the machine adopts the continuous extrusion mode, there is no need to make the extrusion discus used by other manufacturers in the extrusion process, so many intermediate processes and actions are simplified.

5.5. The die head of the machine adopts the front, and an opening and closing movable plate is added. The extrusion die head is installed on this plate, and two oil cylinders are provided to support it from both sides to prevent the movable plate from retreating. When it needs to be opened, the movable plate is pulled and slid through the two oil cylinders to facilitate the assembly and disassembly of the extrusion die.
6. The extrusion die head adopts double-layer structure and is made of special high-temperature resistant materials through special heat treatment process. It has the characteristics of high pressure resistance, high temperature resistance and high hardness, so as to prevent the risk of hardness reduction due to the increase of die head temperature. The die head of the machine is heated by electromagnetic induction heating, which is efficient and fast, which can not be realized by using resistance heating ring. However, the use of electromagnetic induction heating can realize various temperatures required by the die head process, and can better meet the requirements of various production processes.

7. The Metal Extrusion Machine has the ability of automatic mold opening and closing and mold out. It is equipped with two mold opening and closing oil cylinders, which are placed on the left and right sides of the machine. After the oil cylinder pushes open the movable plate of the movable die head, it is equipped with a mold-out oil cylinder, which is installed on the front seat.

The precious metal wire annealing furnace is a high-temperature equipment used for annealing precious metal wires. It is usually used in the production process of precious metal products (such as gold, silver, platinum, palladium, etc.), especially in the manufacture of electrical, jewelry, and high-end electronic components, and plays a very important role.

Working principle:

1. Heating process: The annealing furnace increases the temperature in the furnace through a heating system. Usually, the heating temperature varies according to the characteristics of different precious metals. For example, the annealing temperature of gold and silver is generally between 300°C and 600°C, while platinum and palladium require higher temperatures.

2. Constant temperature maintenance: After reaching the required temperature, the temperature in the furnace will be maintained for a certain period of time to ensure that the lattice structure in the metal is adjusted and the internal stress is eliminated.

3. Slow cooling process: The annealing process usually requires the temperature in the furnace to cool down slowly to avoid metal embrittlement caused by rapid temperature changes.

Advantages of wire annealing furnace:

1. Improve the ductility of metal: Through annealing, the ductility and plasticity of precious metals are improved, making it easier to process into the desired shape.

2. Eliminate internal stress: Precious metal wires will produce internal stress during cold processing, and annealing can eliminate these stresses and reduce the risk of metal cracking.

3. Improve surface finish: By controlling the atmosphere in the furnace and the annealing process, oxidation or contamination problems on the surface of precious metals can be effectively controlled.

[Laser marking machine principle]

The principle of laser marking machine is to utilize a laser beam to create permanent marks on the surfaces of various materials. This is achieved by evaporating the surface material to expose deeper layers, causing chemical and physical changes through light energy to “engrave” traces, or by burning away portions of material to reveal desired patterns or text.

Laser marking machines are mainly categorized into CO₂, semiconductor, fiber, and YAG laser marking machines. While typically associated with surface-level alteration, it is important to note that the technology is closely related to laser engraving, with the key difference often lying in the processing depth. Critically, modern laser marking machines can achieve engraving functionality through parameter adjustment, enabling them to create deeper, tactile marks when required.

These systems are primarily used in applications demanding high precision and fine details, such as electronic components, integrated circuits, mobile communications, hardware products, precision instruments, jewelry, auto parts, and PVC pipes, where the distinct, durable marks produced are often essential.

[Advantages of Laser Marking and Laser Engraving]

High Precision: Both laser marking and laser engraving machines use a laser beam for processing, offering extremely high precision and resolution. They enable the clear marking or engraving of tiny text, complex patterns, and fine details.

Non-Contact Processing: Both laser marking and engraving are non-contact methods. The laser beam acts directly on the object’s surface without physical touch, eliminating mechanical stress or tool wear, which is crucial for delicate parts.

High Speed: Laser marking machines offer fast marking capabilities, enabling efficient production. The laser beam moves rapidly, and the marking speed can be adjusted to suit high-volume production needs. Similarly, modern laser engraving machines provide high processing speeds for efficient engraving workflows.

Wide Material Applicability: The laser marking machine is suitable for various materials, including metals, plastics, wood, ceramics, and glass. Laser engraving machines also share this versatility but are particularly preferred for applications involving deeper engraving into materials like wood, acrylic, leather, and certain metals.

Flexibility: Laser marking machines can achieve various marks, including text, patterns, barcodes, and QR codes. Users can freely design and switch marking content as needed. This programmability is a key advantage shared with laser engraving machines, which can effortlessly switch between different deep engraving patterns and designs, offering great flexibility for customization and short production runs.
