Aluminium Extrusion Profile for Curtain Wall appear short, crossed defects for several reasons are as follows:
Features reflect:
There is a certain depth of white, vertical distribution in the aluminum surface, intermittent or sporadic appearance, aluminum alloy tail more than the front of the serious oxidation after the gray-black.
cause:
(A): aluminum extrusion cylinder, aluminum extrusion pad between the size of the ultra-poor, aluminum particles into the metal
(B): aluminum extrusion die used for too long, hardness is not enough.
(C): extrusion speed and extrusion temperature too fast too high, poor quality rod.
In a parallel line, intermittent short white crossed, which is caused by the mold hole. Irregular short stripes are punched by metal particles, which is the size of the extrusion tool with the tolerance.
Elimination:
The extruding cylinder, the mating size between the pressing pads shall not exceed 0.1mm, and the working part of the extruding cylinder shall not exceed 1.0mm with the non-working part (chamfering mouth of the extruding cylinder inlet). Aluminum extrusion die work with smooth no tooth mouth,Aluminium Extrusion Profile for Curtain Wall hardness assurance. Aluminum rods qualified, aluminum extrusion process is correct.
1. Aluminum extrusion processing after cnc processing less: As the aluminum alloy can be squeezed into any complex cross-section, so, as long as the design is reasonable, squeeze the aluminum alloy can also be easily assembled, thereby reducing the machining needs. Some shape can only be obtained by extrusion,Aluminium Extrusion Profile for Curtain Wall through other processes can not be achieved.
2. Aluminum Extrusion Profile Machining Mold Low Cost: Aluminum Extrusion Mold Costs are Low compared to rolling, casting, forging, and other competing materials.
3. High structure efficiency: aluminum alloy extrusion profiles can achieve maximum structural efficiency. Where you need to increase the strength you can use Tianmao profiles.
4. Light weight: extruded aluminum alloy profiles light weight, high strength, and durable. Due to the difference in the performance of aluminum and other competing materials, the same effect of aluminum structure is only about half the weight of other metal structures, and other metals are not easy to process.
5. Aluminum extrusion profile surface treatment effect is diverse, and corrosion resistance: through powder or electrophoretic coating and other surface treatment,Aluminium Extrusion Profile for Curtain Wall the designer can achieve any desired color. Of course also includes natural silver or color anodized film.
6. Maintenance is less: aluminum is a natural and durable metal, and aluminum extrusion aluminum surface treatment after processing more enhanced its durability
