- Fluidized bed coating method (also known as fluidized bed)It is composed of a porous partition and a container, with the porous partition dividing the container into upper and lower parts.Working process: Compressed air is introduced into the container below the partition, and the compressed air passes through the porous partition to suspend the powder abo
- Advantages of Dacromet coating1. Excellent corrosion resistance: Although the thickness of the Dacromet film layer is only 4-8 μ m, its rust prevention effect is 7-10 times higher than that of traditional electroplating, hot-dip galvanizing, or coating methods. After more than 1200 hours of salt spray resistance test, no red rus
- Methods for removing burrs from parts-11、 Coarse level (hard contact) methodCutting: Removing burrs with a cutting tool is a common traditional method. Suitable for deburring larger burrs or parts that do not require extremely high precision. However, this method may leave tool marks on the surface of the parts, requiring subsequent proc
- Why can't gears have less than 17 teeth? What would happen if they were missing?Gears are a widely used spare part in daily life, whether it is used in aviation, cargo ships, automobiles, and so on. However, there are requirements for the number of teeth in the design and processing of gears. Some people say that if it is less than 17 teeth, it cannot rotate, while others say i
- Heat treatment: surface heat treatmentThe process of placing steel parts in a chemical medium containing one or several infiltrating elements, and diffusing the infiltrating elements from the surface to the interior through heating, insulation, and cooling is called chemical heat treatment. The purpose of chemical heat treatment is to i
- Which can better improve the corrosion resistance of steel parts, blackening or bluing?In industrial manufacturing, anti-corrosion treatment of steel parts is crucial, as it relates to the service life and safety of the product. Among numerous anti-corrosion treatment methods, blackening and bluing are two common and effective means. These two processing methods have some similarities
- Flat gasketFlat gasketThe main function of a flat washer is to increase the contact area, disperse the pressure of the bolt head or nut on the surface of the connected part, and prevent the surface of the connected part from being damaged or deformed due to excessive local pressure. For example, when connectin
- What are the problems with fine and high teeth?Strength calculation is complexDue to the special tooth profile of fine and high tooth gears, their strength calculation method is different from traditional gears. It is necessary to consider the influence of factors such as tooth height, tooth shape, and coincidence, and adopt more complex calcula
- Spring washer (spring washer)Spring washer (spring washer)The main function is to prevent loosening. Its unique wavy structure is compressed after the bolt is tightened, generating a reverse elastic force that can effectively prevent the nut from loosening due to dynamic loads such as vibration and impact during equipment opera
- Heat Treatment: Surface Heat Treatment - Chemical Heat TreatmentThe process of placing steel parts in a chemical medium containing one or several infiltrating elements, and diffusing the infiltrating elements from the surface to the interior through heating, insulation, and cooling is called chemical heat treatment. The purpose of chemical heat treatment is to i
