Aluminium profile shot blasting machine
Description
Aluminum profile shot blasting machine is a machine that is powered by compressed air to spray the surface of the workpiece with medium materials at high speed, which changes the mechanical properties of the outer service of the workpiece.
Through the shot blasting treatment, which can remove the die line and scratch of aluminum profiles surface, improve the appearance quality and coloring adhesion, so that we can get the result that improves the quality of the product
The Aluminum Profile Shot Blasting Machine plays a crucial role in preparing aluminum profiles for further processing like painting, anodizing, or other surface treatments.
It utilizes a powerful stream of abrasive media such as steel shot, or glass beads to clean and pre-condition the surface of the profiles, ensuring optimal adhesion and finish quality.
Function:
Feeding System: The profiles are securely fed into the machine through rollers or conveyors.
Shot Blasting Zone: Profiles encounter a controlled stream of high-velocity abrasive media, effectively removing:
Mill scale: The oxide layer formed during extrusion.
Contaminants: Oil, grease, dirt, and other residues.
Surface imperfections: Light scratches, burrs, and casting marks.
Abrasive Recirculation: The spent media is collected, separated from debris, and recirculated for efficient use.
Dust and Fume Extraction: Powerful systems ensure a clean working environment and protect operators from airborne dust and fumes.
Output Conveyor: Clean and prepped profiles emerge from the machine ready for further processing.
Key Features:
Adjustable blasting parameters: Control media type, blasting pressure, and exposure time for optimal results on different profile types and desired finishes.
Durable construction: Robust materials withstand the wear and tear of abrasive blasting processes.
Safety features: Interlocked systems and emergency stop buttons ensure operator safety.
Environmental considerations: Some models incorporate dust filtration and media recycling systems to minimize environmental impact.
Customizable configurations: Cater to specific profile sizes, shapes, and production requirements.
Advantages:
Superior surface cleaning: Shot blasting delivers more thorough and consistent cleaning compared to manual methods, maximizing adhesion for subsequent surface treatments.
Enhanced coating performance: A clean and prepped surface ensures superior paint, anodize, or other coating adhesion, leading to a longer-lasting and aesthetically pleasing finish.
Improved efficiency: Automated blasting processes are faster and more consistent than manual cleaning, potentially increasing production throughput.
Versatility: Accommodates diverse profile shapes and sizes, making it suitable for a wide range of applications.
Cost-effectiveness: Shot blasting can improve coating performance and lifespan, potentially reducing long-term maintenance and replacement costs.
Aluminum profiles have the following advantages through shot blasting:
⭐It can remove the oxide film on the surface of aluminum profile products.
The naturally formed oxide film can be removed by sandblasting.
This is why the sandblasting process precedes the anodizing process.
⭐ Prepare for other surface treatment processes, aluminum profiles after sandblasting, the electrophoretic paint film has stronger binding force in the process.
⭐Improve the mechanical properties of aluminum parts.
Sandblasted aluminum parts can increase the roughness by 0.1-0.5μm.
There are also tiny depressions on the surface of the parts that can store lubricating oil.
The lubrication effect is better, thereby extending the length of aluminum parts. service life and reduce mechanical operating noise.
⭐ Removing tiny burrs from aluminum profile parts, especially precision parts, has very high requirements for smoothness.
Tiny burrs will cause defects in the parts.
For example, 3C communication parts, textile machinery parts, aerospace precision parts, medical equipment parts, etc.
After sandblasting treatment, tiny burrs can be removed and a smooth surface can be obtained.
⭐ Solve the problem of metal reflection.
Some aluminum products are strictly prohibited from being reflective.
For example, for some surgical instruments, sandblasting is an effective solution.
⭐ Through sandblasting, the damage to the environment caused by the sanding process of chemical corrosion is solved, and low-cost and environmentally friendly production is achieved.
Working principle
Workpiece on the input position, through the roller conveyer, going through the shot blasting chamber at uniform speed.
Turn on the shot blasting device, then the blast wheel starts to work.
The surface of the workpiece will get consistent roughness after impacting the ball at high speed.
The ball will be sifted through the circulation and separation system, the dust will be absorbed, filtered and discharged through the dedusting system.
Benefits
Appropriate shot blasting volume, and low consumption blasting wheel, can significantly improve blasting efficiency, and satisfactory quality of cleaning.
The layout mode of the shot blasting chamber and blast wheel is determined after the computer simulation of the projectile, which is comprehensive and thorough for the sandblasting pieces.
Drip bag dust collector, high efficiency for dust collecting, low consumption, good cleaning regeneration performance, low cost, convenient replacement and maintenance.
Using a separation device that took eddy current pneumatic separation way, separating the dust, effective shot materials, aluminum oxide, and broken materials from the large particles, makes the workpiece good appearance, high efficiency and consistent quality.
The automatic unloading sand system uses air pressure, an air cylinder, an automatic unloading plate, a motor, automatic feeding rack, which is to facilitate the unloading by workers, prevent the loss of sand, and to prevent the wear and tear of the work piece in the process of manually unloading sand.
