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.

Introduction to global aluminum ore types

Global bauxite deposit types can generally be divided into two major categories: laterite type and sedimentary type.

The ore of laterite bauxite deposits is mainly gibbsite or a mixed type of gibbsite and boehmite. It is characterized by medium aluminum, low silicon, high aluminum to silicon ratio, and high iron. It is a high-quality raw material for the aluminum industry. , easy to harvest and soluble. The reserves of this type of deposit account for about 88% of the world's total aluminum ore reserves. It is the world's main bauxite deposit. It is mainly distributed in the tropical and subtropical ranges between 30° north and south latitude, generally in the offshore plains and mid-low highlands on the edge of the continent. , mesas and islands are visible.

Sedimentary bauxite deposit reserves account for about 11% of the world's total aluminum ore reserves. This type of bauxite deposit presents a variety of ore types due to different ore control times and regions. For example, China's karst bauxite deposits are mainly diaspore type, and the ore characteristics are high aluminum, high silicon, medium Low aluminum to silicon ratio and low iron; karst bauxite deposits in the Mediterranean and Caribbean areas contain both boehmite, gibbsite and various mixed ores. Global sedimentary bauxite deposits are mainly distributed in temperate areas near 30°-60° north latitude.

Precautions when using extruded aluminum molds:

1.Mold installation: When installing the mold, it is necessary to ensure that the mold is installed in the correct position and fixed stably to avoid the mold from shifting or falling off during the production process.

2. Temperature control: The mold will generate a lot of heat during use, and the temperature of the mold needs to be effectively controlled to prevent the mold from overheating and causing deformation or damage.

3. Cleaning and maintenance: During the use of the mold, regular cleaning and maintenance are required to ensure the service life of the mold. When cleaning, avoid scratching with hard objects to prevent damage to the mold surface.

4. Avoid overuse: During the use of the mold, excessive use should be avoided to prevent premature wear of the mold. Generally speaking, molds need to be replaced after being used for a period of time to ensure product quality.

5. Use appropriate lubricants: During the use of the mold, appropriate lubricants should be used to reduce mold wear and improve production efficiency.

6. Regular inspection: During the use of the mold, the mold needs to be inspected regularly to find out whether there are cracks, deformations and other problems in the mold so that they can be dealt with in a timely manner.

7. Use special tools: When disassembling and installing the mold, special tools should be used to avoid mold damage caused by using inappropriate tools.

8. Train operators: Operators need to receive professional training to understand the usage and precautions of the mold to avoid mold damage due to improper operation.

Quenching Furnace  

The quenching furnace is a furnace that heats the workpiece before quenching.

Quenching is to put the workpiece into the furnace and heat it to the quenching temperature above the critical point and keep it for a period of time, then quickly take the workpiece out of the furnace and put it into the quenching liquid (oil or water) for quenching.

The heat source of the furnace can be electricity and fuel, and the temperature can be measured by a thermocouple.

Furnaces using electricity, gas, and liquid fuels can be automatically controlled and regulated by instruments.

Our quenching standard:
After heat treatment for 14 hours, the hardness reaches 50-52 degrees.

If you are looking for Architectural aluminum profile mold, Decorative Aluminum Profile Mold, Industrial Aluminum Profile Molds and Furniture Aluminum Profile Mold,  we are the perfect Aluminium Extrusion Mould manufacturer from China for you.

Tempering Furnace  

The tempering furnace is used for tempering general metal parts in air and quenching, annealing and aging heat treatment for aluminum alloy die-casting parts, pistons, aluminum plates and other light alloy parts.

The shell is welded by steel plate and section steel, and the trolley is welded by section steel and steel plate.

The trolley can reduce heat radiation and convection loss through soft contact with the furnace lining and sand sealing mechanism, and effectively ensure the sealing of the furnace body.

(Our tempering standard: 2 times*10 hours)
