Comparison between aluminum alloy sliding doors and iron doors

Aluminum sliding doors differ from iron doors in the following aspects:

1. Material: Aluminum alloy sliding doors are made of aluminum alloy materials, while iron doors are made of iron materials. Aluminum alloy is lightweight, corrosion-resistant, and oxidation-resistant, while iron doors are relatively heavy and prone to rust.

2. Appearance: Aluminum alloy sliding doors have a modern and simple appearance, suitable for modern home styles. Iron gates, on the other hand, are more traditional and classical, suitable for antique architectural styles.

3. Installation and maintenance: Aluminum alloy sliding doors are relatively light and easy to install and maintain. Iron doors are relatively heavy and require more manpower and time to install and maintain.

4. Price: Generally speaking, the price of aluminum alloy sliding doors is relatively high, while the price of iron doors is relatively low.

5. Service life: Aluminum alloy sliding doors have a long service life and are not susceptible to oxidation and corrosion. Iron doors are prone to rust and require regular anti-rust treatment.

The right door type needs to be chosen based on your specific needs and budget. If you are pursuing modern style, lightness and corrosion resistance, you can choose aluminum alloy sliding doors; if you are pursuing traditional style and economy, you can choose iron doors.

Classification of Aluminum Extrusion Dies

1. Classified by the section shape of the die hole compression zone

It can be divided into: flat die, conical die, flat cone die, streamlined die and double cone die, etc., 

2. Classified by the types of extruded aluminum profiles.

It can be divided into bar molds, ordinary solid profile molds, wall panel molds, variable-section profile molds, pipe molds, and hollow profile molds.

3. Classified by the number of die holes

It can be divided into single-hole die and multi-hole die;

4. Classified by the extrusion method and process characteristics

It can be divided into hot extrusion die, cold extrusion die, hydrostatic extrusion die, reverse extrusion die, continuous extrusion die, water cooling die, wide expansion die, horizontal extrusion Machine molds and vertical extrusion machine molds, etc.

5. Classified by the mold structure

It can be divided into integral mold, hollow die, removable mold, movable mold, tongue-shaped combined mold, plane split combined mold, embedded mold, fork mold, front mold, protective mold, etc.

6. Classified by the shape and structure of the mold

It can be divided into a cone mold with an inverted cone, a cylindrical mold with a boss, a cone mold with a positive cone, a conical-middle cone ring mold with an inverted cone, and an inverted cone mold. Cylindrical-conical molds for cones, reinforced molds, etc.

The Main Advantages of Hollow Mold

1.It can extrude hollow profiles or pipes with double-hole or multi-hole inner chambers, and can also produce multiple hollow products at the same time, so the production efficiency is high, which is difficult or even impossible to achieve with bridge tongue molds;

2.It can extrude semi-hollow profiles with large cantilever beams that are difficult to produce with plane dies;

3.Removable, easy to process, low cost;

4.Easy to separate residual materials, simple operation, short auxiliary time, the extrusion cycle can be completed with ordinary tools on ordinary bar extruders, and at the same time, the residual materials are short and the yield is high;

5.Continuous extrusion can be realized, and products of any length can be cut according to needs;

6.The number, size and shape of the split holes can be changed, so that the cross-sectional shape is relatively complex, the wall thickness difference is large, and it is difficult to use the working belt, the obstruction corner, etc. to adjust the flow rate of the hollow profile well;

7.A taper split hole can be used to extrude a hollow product with a larger shape on a small extruder, and it can ensure sufficient deformation.
