アルミ押し出しプロセスとは何ですか？ （押し出しアルミガイド2020）

今日、アルミニウム押し出しプロセスは、構造物の建設、特に次のような構造物で広く使用されています。

• ドア
• ウィンドウズ
• パーティション
• 換気され、
• 半透明のファサード

押し出すとは、材料を強制的にオリフィスに通すことです。 業界一般では、材料の押し出しは、材料を成形し、特定の特性を与えるために使用されます

アルミ押出成形とは？

The pressing or extrusion process can be applied to aluminum profiles and bronze, brass, stainless steel or titanium. Although it is the extrusion of aluminum that has become widespread due to its low melting point (about 500 ° C).

1.1. Aluminum and steel

The extrusion process makes it possible to produce aluminum profiles in widths from 10 to 800 mm. Thanks to an unlimited range of various cross-sectional shapes. The cost of tools for making a new extruded section from aluminum is much cheaper than for making a rolled steel section.

Moreover, the downtime of the extrusion press when changing the die is significantly less. It is due to the time it takes to change the rolls of a rolling mill in the production of steel profiles.

Therefore, aluminum extrusion process produces extruded aluminum profiles. An aluminum extrusion company can carry the order according to customer drawings in order to fulfill specific tasks in a structure or product. One of the main features of the extrusion process of profiles is that they can have very thin elements.

1.2. Direct compression method: aluminum extrusion process

Aluminum profile production technology or how aluminum products are made.

The technology for manufacturing an aluminum profile is a complex process. But in order to have an idea of ​​this process, it is enough to know the basics. And in this article in a simple and understandable form, we will try to outline the whole essence of aluminum extrusion process.

So where does it all start?

製造時の非常に高い温度では、アルミニウムポールはアルミニウム原料から鋳造されます。 次に、アルミニウムプロファイルの押し出し（プレス）があります。 アルミニウムから製品を製造するプロセスが存在する可能性があります。

アルミ押出成形技術

まず、ダイの加熱が始まります。

ダイとは何ですか？

アルミプロファイルを押し出し成形した形状の工具です。 標準プロファイルが作成されている場合、そのツールは通常、鋳造工場で入手できます。 非標準プロファイルの作成について話している場合、必要なダイは事前に作成されます。

• ビレットは押出ラインにロードされます。
• 非常に高い温度で、アルミニウムを塑性状態に加熱するプロセスが行われます。
• 加熱されたワークピースはのこぎりで切断されます。
• 次に、アルミニウムがプレスにロードされ、高圧押出プロセスが行われます。

The die is installed in the press. And the aluminum profile is extruded through the prepared tool. And it is automatically cut to a certain size. So you can see アルミニウム押し出しプロセスis not as simple as we read it.

The resulting aluminum profile is leveled. We can say the process of "stretching" takes place.

But at the next stage, the aluminum profile is being cut into dimensions according to the order from the client.

Automatically and evenly, the profile is placed in a tank for heat in a special oven. This gives the aluminum profile its strength.

The product from the aluminum profile is ready! Next, the profile is usually packed in foil and then in cardboard.

On request, the finished product from the aluminum profile can be powder painted in any color. The standard is painted according to the RAL catalog.

Types of aluminum extrusion

The アルミニウム押し出しプロセスoccurs the metal billet deformation in order to adapt it to the most different applications. It all starts with the billet. This, after passing through a hole those models it for a specific applicability. In addition, it forms the aluminum profiles used in civil construction and in finished products.

2 Methods of Aluminum Extrusion

In any extrusion process, there are two ways to do the job, which depend on the ductility of the material. In the case of aluminum, the method used is high temperature extrusion.

The phenomenon is similar to the operation of an injection syringe. The aluminum billet is injected at high pressure and temperature and is propelled to a mold. Through which it gains the desired shape. After this step, it takes the form of a solid part and can be cut as the manufacturer wishes.

How to classify aluminum extrusion process?

Due to its immense use in civil construction and the furniture industry, the aluminum extrusion process has an infinite variety of profiles. They can be classified as solids, in which the cross section has no gaps circumscribed by metal.

The tubular profile, on the other hand, is one that presents a cross section with at least one void totally circumscribed by metal. There are also semi tubular profiles, whose cross sections have voids partially circumscribed by metal.

結論

Despite the malleability of aluminum、aluminum extrusion process allows any type of extrusion. There are some groups of alloys. They imply a greater range of properties for the extrusion, giving maximum efficiency in the process. Each of them has individual characteristics.

They can be easily extruded; others require a more complicated process, which even involves reducing the speed of extrusion
