1. Zinc alloy die-casting molds are generally made of H1SKD68407 and other materials. To tell the truth, the working temperature of the zinc alloy die-casting mold is right, and the red hardness of the mold steel is not high, and the national standard hot work die steel can meet the general zinc alloy die-casting mold.
2. What material is used for the die casting mold The core material is made of hot mold steel, which is too much for SKD6DAC, DH-3840841H13Cr2W8V, 4Cr5Mosiv, 234W302, etc. Most of the mold frames are made of cast steel, ductile iron, medium carbon steel, etc. For example, qt55qt60s50c.
3. At present, the commonly used zinc alloy die-casting mold materials include: H13 steel: with high strength, high hardness and good wear resistance, it is suitable for the production of large-scale and high-demand zinc alloy die-castings. 8407 steel: with high strength, high hardness and good corrosion resistance, it is suitable for the production of zinc alloy die castings with high requirements.
4. The ways to improve the service life of zinc alloy die-casting molds are: choosing high-quality mold steel. Good mold design and manufacturing process. Optimized treatment process, operation specifications, maintenance and maintenance during use.
5. Description of the properties of die-casting zinc alloy materials: the application of commonly used zinc alloys: for example, it is better to use za-za-8 for mobile phone accessories, such as face shells; ZAZ-12 is better for internal parts such as brackets.
6. Mr. Long, an old customer in Foshan, consulted that there is a set of small-size zinc alloy die-casting molds with a large output, and now SKD61 mold steel is used for a period of time, and it is a little annoying to get off the machine for maintenance. It's not that it can't be used, it's a little time to produce, the product has more burrs, and you have to trim it, and you want to see what mold steel you have, you can use it a little bit, and repair a little less mold.
1. Zinc alloy is a non-ferrous alloy composed of zinc as the matrix and adding other elements. The main alloying elements are aluminum, copper, magnesium, etc. Zinc alloys have a low melting point, good fluidity, easy plastic processing and welding, and are resistant to atmospheric corrosion. According to the manufacturing process, it is divided into cast zinc alloy and deformed zinc alloy.
2. Zinc alloy is made of zinc plus aluminum, magnesium, lead and titanium and other elements, which not only has a low melting point and good fluidity, but also is easy to weld and can resist corrosion in the atmosphere. At the same time, the waste material of zinc alloy can be remelted, but the creep strength is low, and it is easy to produce dimensional changes in natural aging.
3. What is the material of zinc alloy, zinc alloy is an alloy composed of zinc based on zinc and other elements. Commonly added alloying elements include aluminum, copper, magnesium, cadmium, lead, titanium and other low-temperature zinc alloys.
4. What is the material of zinc alloy Zinc alloy is a metal material, the main component of which is zinc. Zinc alloys are usually composed of elements such as zinc, aluminum, copper, and magnesium, which have degree, corrosion resistance, and good processing properties. The main component of zinc alloy is zinc, which is characterized by light weight, high hardness and strong corrosion resistance.
5. The material is different, the main raw material of zinc alloy is zinc-based, and then added to the alloy made of other elements, while aluminum alloy is a non-ferrous metal material, often adding aluminum, copper, magnesium and other alloy materials, although the density is low, but the strength is high, and high-quality steel is similar. The mechanical properties are different, the hardness of zinc alloy is 65-140, and the tensile strength reaches 260-440.
6. Zinc alloy is an alloy composed of zinc based on zinc and other elements. Common alloying elements include aluminum, copper, magnesium, cadmium, lead, titanium and other low-temperature zinc alloys. Zinc alloy has a low melting point, good fluidity, fusible welding, brazing and plastic processing, corrosion resistance in the atmosphere, and the residual waste is easy to remelt.
However, the creep strength is low, and it is easy to cause dimensional changes due to natural aging.
