Industrial aluminum profile dies for automation equipment

The Difference Between Solid Die and Hollow Die

Solid Die

The solid die is relatively simple, as long as the split hole is designed, the aluminum handle is squeezed out of the flat flag hole to form a cross section after mixing.

Like aluminum flat strips, aluminum rods, some special-shaped materials, etc.

Hollow Die

Hollow dies are generally combined by two combined molds, so that the cavity can be formed by splitting the flow through the working belt during extrusion, such as aluminum shells and round tubes.

For ordinary extrusion dies, to produce hollow profiles, a splitter die must be used, which consists of an upper die and a lower die. The upper die is generally used to guide flow and position the hollow part of the hollow profile. The lower mold is the outer surface working belt and empty knife.

Most of the non-hollow profiles use solid dies. Generally speaking, there is only one mold including diversion and working belts. Of course, there are special cases. Here we only explain the general production conditions.

Advantages of aluminum alloy railings：

1. Corrosion resistance: Aluminum alloy railings will not rust due to moisture in the air or other acid and alkali substances, so their service life is much longer than ordinary iron railings.

2. Beautiful: Aluminum alloy railings have a high appearance finish and bright color, and the color can be freely selected, which can greatly improve the aesthetics of the building.

3. Easy maintenance: Aluminum alloy railings do not require frequent maintenance and repairs. They only need to be cleaned regularly to maintain their beauty.

4. Lightweight and high strength: Aluminum alloy railings are light in weight, but high in strength, not easily deformed, and have good safety performance.

5. Environmental protection: Aluminum alloy railings are a recyclable material and have little environmental pollution.

6. Easy installation: The installation of aluminum alloy railings is simple and quick, and does not require complex installation tools and techniques.

7. Reasonable price: Compared with railings made of other materials such as stainless steel and wood, aluminum alloy railings are more affordable and cost-effective.

What are the benefits of using aluminum alloys for parts in the automobile manufacturing industry?

Aluminum alloy materials are currently widely used in the production of automobile parts. Because vehicles are becoming lighter and lighter, aluminum is lighter, stronger, and resistant to corrosion and rust, so it is used more and more. Let’s briefly introduce it below application characteristics.

1. During the extrusion process, the metal obtains a more intense and uniform three-dimensional compressive stress state in the extrusion deformation zone than rolling and forging. Therefore, extrusion can fully exert the plasticity of the metal being processed and can be used for rolling of difficult-to-deform metals. After processing and forging, it can also be used to manufacture various hollow or solid complex cross-section components.

2. Due to the variable geometric cross-section of aluminum alloy profiles, the stiffness of its parts is relatively high, which can increase the stiffness of the body and improve the dynamic control characteristics of the vehicle.

3. Since the cross-section of aluminum alloy profiles can be controlled, the functional integration of components can be improved, the number of components can be reduced, and welding positioning can be achieved through cross-sectional matching.

4. For products with extrusion benefits, the longitudinal strength properties (Rm, Rp0.2) after quenching and aging are much higher than similar products processed by other methods.

5. The surface of aluminum extruded products has good color and corrosion resistance, and no other anti-corrosion surface treatment is required.

6. The extrusion process has high elasticity, low mold cost, and low design change cost.
