I. What is aluminum profile mold opening?

1. The aluminum profile mold opening process refers to the process of processing aluminum materials into the required shape through molds. Generally speaking, the aluminum profile mold opening process can be divided into the following steps: Designing the mold: First, the mold needs to be designed according to the product requirements and design drawings.

2. Aluminum forming requires molds, generally extrusion forming, which requires the opening of aluminum molds. Under the action of three-dimensional non-uniform compressive stress, the blank is extruded from the hole or gap of the mold to reduce its cross-sectional area and increase its length. The processing method to become the required product is called extrusion, and this processing of the blank is called extrusion molding.

3. The meaning of aluminum profile mold opening is to customize aluminum profiles according to drawings or samples. Generally, in the field of aluminum profiles, there are distinctions between non-standard and standard aluminum profiles. Standard aluminum profiles are actually profiles with unified specifications and styles, such as industrial aluminum profiles 4040 and 8080. It is a bit like the previous computer USB port, which are all unified.

4. Aluminum profiles are a kind of profiles extruded from aluminum bars through molds with different cross-sections. Aluminum profile forming requires molds, generally extrusion forming, which also requires aluminum profile mold opening. Today, let's talk about what is aluminum profile mold opening? Generally, we divide aluminum profiles into standard profiles and non-standard profiles. Standard profiles refer to profiles with unified specifications and styles.

5. Mold-opening aluminum materials Mold-opening aluminum materials are also industrial aluminum materials obtained by extruding aluminum alloy materials through an extrusion cylinder. After a series of processes, they become the same as conventional profiles.

6. What does aluminum profile mold opening mean? Aluminum forming requires molds, generally extrusion forming, that is, aluminum mold opening. Under the action of three-dimensional non-uniform compressive stress, the blank is extruded from the hole or gap of the mold to reduce its cross-sectional area and increase its length. The processing method to obtain the required product is called extrusion, and this processing of the blank is called extrusion molding.

II. What materials are generally more durable for aluminum profile molds?

1. For molds made of aluminum materials, high-speed steel, molybdenum steel, and 4Cr13 stainless steel are all relatively suitable choices, but the specific choice needs to be considered according to the actual situation. The choice needs to be made after comprehensive consideration of factors such as mold cost, service life, and material quality.

2. Steel molds are one of the traditional mold-making materials, with advantages such as high hardness, good wear resistance, and corrosion resistance. Steel mold-making technology is mature, has a long service life, and is suitable for large-scale production and the production of large products. However, steel molds also have some shortcomings.

3. The toughness of LG mold steel is 8-9 times that of DC53, with a hardness of HRC56-58, and can be mirror-polished to 10,000-12,000 numbers. LG mold steel has high hardness, good toughness, good microstructure uniformity, naturally will not stick aluminum powder, and is wear-resistant. Some customers use LG mold steel to stamp aluminum solar frame products, and the mold life is 5 times that of SKH-51 high-speed steel.

4. The choice of mold material directly determines the life and use effect of the mold. At present, the main materials for making stamping aluminum molds are high-speed tool steel, alloy steel, cemented carbide, etc.

5. For molds that crack, using LG mold steel with good toughness will not crack! After understanding, it is known that the punch of his aluminum extrusion mold has excessive material during cold extrusion and adheres to the punch, commonly known as a build-up.

6. Typical die-casting aluminum mold materials The choice of die-casting aluminum mold materials is very diverse. Common ones include aluminum alloys, steels, high-hardness alloys, and high-temperature alloys. Aluminum alloy is a common material for die-casting aluminum molds. Its strength and corrosion resistance are very good, and the price is relatively low. Commonly used aluminum alloy materials include ADC12, A380, A390, etc.
