Generally we buy aluminum tubes are dependant on the name of it has the manufacturing process, such seeing that cold drawn aluminum tubes plus extruded aluminum tubes. Even so, what is the difference within their craftsmanship, and which procedure caused the difference, remains a mystery to most of the people. If you're interested, examine this article.

Easy methods to Produce Cold Drawn Metal Tube?

Extruded Aluminum Tube vs Cold Drawn Aluminum Tube



How To Manufacture Extruded Aluminum Tube?

Aluminum tube extrusion molding should be to put a strong pressure within the metal blank placed inside mold cavity,,which forces the metal blank to produce directional plastic deformation and extrudes it on the die hole of the extrusion die so that you can obtain the required section shape, size and parts or semi-finished extruded aluminum tubes with certain physical properties.

Enhance plasticity

The extruded metal can get yourself a more intense and uniform three-way compression stress state in the deformation zone than this rolling forging, which will give full play to the plasticity with the processed metal itself.

Generation diversification

Extrusion molding can not only produce bars, tubes, moulds and wires with simple combination section shapes, but additionally produce profiles and light weight aluminum tubes with complex mix section shapes.

Flexibility

That flexibility of extrusion molding, really need to replace the mold along with extrusion tools, you can easily produce aluminum tubes regarding different shapes, specifications along with varieties on one tools, the operation of upgrading the extrusion mold is actually simple and quick, time period saving, efficient.

High detail

High precision extruded metal tubes have good surface quality. It also improves the employment rate and the give of metal materials. The extrusion process is known for a good impact on the particular mechanical properties of aluminum tubes.

Short process

Small technological process, convenient production, one extrusion can or may be than hot die forging or forming rolling procedure for the overall structure from the larger area, less apparatus investment, low mold fees, high economic benefits.

Extrusion features

Aluminum alloy has very good extrusion characteristics, especially well suited for extrusion processing, can be processed through a ton of extrusion processes and various die structures to get aluminum tube products.





Tips on how to Produce Cold Drawn Metal Tube?

Cold drawn aluminum tube comes from the production process associated with simultaneously applying longitudinal strain and transverse pressure around the material, so as to enhance the strength of aluminum tube. In general, cold drawing processing might be carried out in a unique cold drawing machine.

While in the cold drawing process, the aluminum tube is simultaneously subjected to tension and extrusion plus plastic deformation occurs. The cold drawn aluminum television cross-sectional area is decreased, resulting in cold hardening. The tensile strength might be increased by 40 ~ 90%, even so the plasticity is reduced considerably.

For smaller and better-quality smooth tubes, cold rolling, cold drawing or a combination of the two must become used. Cold rolling will likely be carried out on a two-high mill and also the tube is rolled in an annular pass formed by a circular groove with a variable section and also a fixed tapered head.





Extruded Metal Tube vs Cold Attracted Aluminum Tube

In terminology of installation and utilize, there is no difference between both, just different material side effects.

Extruded aluminum tube includes high cost, good ductility, great oxidation resistance, good bell-mouth difficulty resistance, not easy to leak refrigerant, the weakness is high cost, the employment of a long time could age and harden.

Extrusion molding is unable to only produce aluminum tubes by using simple cross section pattern, but also produce reliable and hollow aluminum tubes using very complex cross part shape. The cross sections with products change in stages along the direction of length and gradually, and many analysts cannot be formed by simply other plastic processing strategies. It also ranges proportions, from very large ones that has a diameter of 500-1000mm on the external circle of section to really small precision ones with a section size like a matchstick.

Cold drawn aluminum tube will be biggest advantage of low-cost, and good bending, twisting than extruded aluminum conduit. Pipes often need that they are bent when installing atmosphere conditioners. But the shortcomings of cold drawn aluminum tube are not to do flared, inadequate pressure resistance, oxidation resistance, it is easy to leak, if not draped insulation cotton, it may be a hidden danger.



Extruded aluminum tubes and cold drawn aluminum tubes have their own advantages and are traditional in industry. We accept many custom requirements, dedicated service for you, if you want to get aluminum tubes, purchase form us is a wise choice.
