Look at our factory equipment strength
Fabricated aluminium products and machining aluminium products are used widely in many industries, like lighting, furniture, architecture, marine, sporting equipment, industrial equipment, electronics and more.
Aluminium fabrication is the process of creating aluminium parts through cutting, bending and shaping. In wide industries, aluminium fabrication can make various parts and structures for machinery, products, and artwork. 
Over the years, the company has been adhering to the "scientific and technological innovation, quality first, the pursuit of perfection" purpose for better management and innovation. 
Mold Workshop
It is worth noting that aluminum profile die is required for extrusion. This industrial aluminum profile extrusion die is made of H13 steel, and the die can only be used after nitriding. Generally, a set of molds is composed of a positive mold, a mold pad and a mold sleeve. The positive mold is composed of working belt, empty cutter, deflector and other parts, each of which has its own role. WJW's specialized mold opening workshop has professional CNC lathes, CNC machining centers, and advanced high-precision processing equipment such as slow wire feeding processing. In order to extrude ultra-high precision products, it is required that the manufacturing accuracy of the die should reach 0.01mm, so that the tolerance of extruded aluminum products should reach ± 0.05mm.

Aluminum Extrusion Production Line
A high-end aluminum profile extrusion line represents the ability of this aluminum profile production enterprise. Good equipment can not only improve production efficiency, but also improve product quality. The extrusion method of aluminum profile extruders can not only produce tubes, bars and profiles with simple section shapes, but also produce profiles with complex sections and shapes, such as profiles with gradually changing sections, shapes and complex profiles or hollow profiles. It is very difficult to produce such profiles by rolling or other processing methods, However, it is very easy to use a complete production line such as aluminum profile extrusion machine and its auxiliary equipment, and the precision is very high, and the quality is completely in line with the standard. With the improvement of the extrusion process of the extruder, it is now possible to produce a wall thickness of (0.3 ~ 0.4) ± 0.10 mm and a surface roughness of Ra0.8 ~ 1.8 μ M high-precision aluminum alloy profiles, which is far beyond the reach of other processing equipment. The use of aluminum profile extruders not only greatly reduces the total workload and simplifies the subsequent processes, but also improves the comprehensive utilization rate and yield of metal materials.
Full Automatic Vertical Aluminum Profile Spraying Production Line
With the growing popularity of door and window customization, and the increase of customer groups, there is a higher demand for personalized doors and windows. Many colors are one of them. In recent years, the national and social requirements for environmental protection have become higher and higher, and the policy guidance has gradually restricted and reduced the production process of high energy consumption and high pollution. WJW's fully automatic vertical aluminum profile spraying production line, fast color change and powder spraying room, can achieve a variety of color change spraying, which is difficult to achieve by anodic oxidation and electrophoretic coating. In addition, powder spraying has obvious advantages in environmental protection. The powder coating contains no solvent, VOC emissions are almost zero, and the environmental protection pressure is low.

In-depth Fabrication of Aluminum Extrusion, Aluminum Profiles
Machining is a part of aluminium fabrication, it plays an important part in most aluminium extrusion component work by removing material from the parent workpiece. Machining service includes cutting, drilling, milling, countersinking, knurling, counterboring, threading, reaming, laser cutting, etc. Aluminium fabrication and machining operation can be done of machines such as CNC milling machine, CNC turning machine, drill, tapping machine, punches or presses, laser cutting machine, laser marking, plasma cutting, and welding machine, CNC bending machine, etc.

Which Alloy Work Best for Aluminium Fabrication?

If your project is made of extruded aluminium, 6063 6060 6061 6082 will be the best material for fabrication. The most popular alloy is 6061, which can be found in nearly all kinds of industries, from aerospace and automotive to packaging and communications.
If you’re looking for high weldability, choose an aluminum alloy in the 5XXX or 6XXX series. 2XXX and 7XXX alloys are not considered weldable.
In most cases, aluminum alloy 3003 is probably the best alloy for bending, then comes alloy 5052 right behind, and 5052 is with better formability than 3003.
Customize Product Surface Treatment
Aluminum turns black when exposed to air for a long time and reacts with other elements. Surface treatment products have corrosion resistance, weather resistance, wear resistance, decorative appearance, long service life and other characteristics. Commonly used surface treatment processes are anodic oxidation, wire drawing sandblasting oxidation, electrolytic coloring, electrophoresis, wood grain transfer printing, spraying (powder spraying) dyeing, etc. Colours can be customized on request.
WJW ALUMINIUM produces powder-coating aluminum extrusion profiles. We provide you with a wide range of RAL colors, PANTONE colors, and custom colors. Powder-coating finish textures can be smooth, sandy, and metallic. Powder coating gloss can be bright, satin, and matt. WJW ALUMINIUM provides a powder coating service for aluminum extrusions, machined aluminum components, and fabricated aluminum parts.
