First, the difference between aluminum profiles and die-castings
1. There is a big difference in the production process between die-cast aluminum and aluminum profiles. Die-cast aluminum is a cast aluminum part formed by injecting aluminum alloy liquid material into a mold through high pressure and cooling and solidification in the mold.
2. Compared with the processing methods of die-casting alloy and profile, the equipment used is different, and its raw materials are made of aluminum ingots with a purity of about 92% and alloy materials are melted into the die-casting machine by the furnace and molded.
3. Aluminum alloy products are divided into die-casting aluminum products and aluminum profile products. The essential difference between the two is that one is made by die-casting molds, and the other is extruded by extrusion molds. The raw materials of both are aluminum alloys (generally aluminum-magnesium-silicon alloys). Aluminum profiles: Aluminum profiles are common, such as screens, aluminum windows, etc.
4. The difference in material between aluminum die-casting and aluminum profile stamping, the two materials used are not the same, the commonly used materials for die-casting aluminum are alloy materials, which are usually called "aluminum alloy die-casting", which has a relatively high melting point and is easy to stick to the film, and the die-casting products need to be treated on the surface.
5. The extruded aluminum profile is extruded by the extruder by heating the round aluminum rod to its critical point. Die-cast aluminum is made from aluminum ingots and alloy materials, melted in a furnace and shaped in a die-casting machine. The shape of die-cast aluminum products can be designed to be the same shape as a toy, with different shapes to facilitate the connection in all directions.
6. The main difference between the two is that die-cast aluminum products have complex shapes and can be cast in arbitrary shapes. Aluminum profile products have a unified cross-section (sawed from any section, the cross-section is the same), such as: pen tube, power bank shell, servo motor shell and so on.
2. What material is used for the extrusion mold
1. Extrusion die, also known as extrusion die, is mostly used as hot forging process in aluminum profile factory, and is generally used more H13 die steel, which is cost-effective and durable.
2. Extrusion die, also known as extrusion die, is mostly used as a hot forging process in aluminum profile factory. At present, H13 die steel is widely used in this stage. This stainless steel plate is cost-effective and durable. At present, the world's leading die steel belongs to Sweden, Germany and Japan. For example, Kobelco's SKD61 die steel quenching HB value can reach 115.
3. The material of ABS extrusion die should be high-quality steel with good high temperature and high pressure corrosion resistance, such as SKD6SKD1H13. Choosing the right mold material can ensure the hardness and life of the mold, avoid damage and deformation of the mold during use, so as to improve production efficiency and product quality.
4. Injection molding = injection molding machine + injection mold; Extrusion = extruder + die, mandrel + cooling water tank.
Among them, injection molding machines and extruders are almost the same, both melt plastics. The difference lies in the mold: the injection mold is an upper and lower mold, which is combined and processed with a cavity, which is the same shape as the product.
5. Press-injection molds are widely used in encapsulating electrical components. The materials used in the manufacture of compression molds are basically the same as those used in injection molds. Plastic extrusion mold is used to form a type of mold for the production of continuous shape of plastic products, also known as extrusion molding head, which is widely used in the processing of pipes, bars, monofilaments, plates, films, wire and cable coatings, profiles, etc.
6. Selection of materials for drawing die: (1) Alloy cast iron composition: C3%, Si6%, Cr4%, Mo4%, and the friction surface is flame quenched. (2) The composition of alloy cast iron is the same, only the friction surface flame quenched to <420HB(3) punch material, except for alloy cast iron, better chrome plating.
