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.

How to distinguish the advantages and disadvantages of aluminum alloy roller shutters

The advantages and disadvantages of aluminum alloy rolling shutters can be judged from the following aspects:

1. Material: High-quality aluminum alloy roller shutters should be made of high-purity aluminum alloy materials, which have good strength and corrosion resistance.

2. Processing technology: High-quality aluminum alloy roller shutters should adopt advanced processing technology, such as precision stamping, bending, welding, etc., to ensure the accuracy and quality of the product.

3. Surface treatment: High-quality aluminum alloy roller shutters should undergo surface treatment, such as anodizing, spraying, etc., to increase their wear resistance, corrosion resistance and aesthetics.

4. Sealing performance: High-quality aluminum alloy roller shutters should have good sealing performance, which can effectively prevent water, gas and dust from entering the inside of the machine.

5. Service life: High-quality aluminum alloy rolling shutters should have a long service life and be able to withstand long-term use and frequent switching operations.

6. Safety performance: High-quality aluminum alloy roller shutters should have good safety performance and be able to prevent accidents, such as pinching, collisions, etc.

To sum up, high-quality aluminum alloy roller shutters should have high strength, corrosion resistance, precision processing, good sealing performance, long service life and good safety performance.
