The wear resistance of electronic scale molds is influenced by various factors, and there are differences in the wear resistance performance of different types of electronic scale molds. The following is a detailed analysis for you:
1. Mold materials
Excellent mold steel: If alloy tool steel such as Cr12MoV is used to make electronic scale molds, it has good wear resistance. This steel contains a large amount of chromium element, which can form fine and high hardness carbides, enhance the surface hardness and wear resistance of the mold, and slow down the wear rate when subjected to long-term forming pressure and friction of electronic scale components.
Special steel or surface treatment: For high-precision electronic scale molds, powder high-speed steel is used. Through powder metallurgy technology, the distribution of carbides is uniform, greatly improving wear resistance. Alternatively, the mold can be nitrided to form a nitride layer with a hardness of up to 1000-2000HV, significantly enhancing the wear resistance of the mold.
2. Manufacturing process
Precision machining: By using CNC machining equipment and processes, the dimensional accuracy and surface roughness of the mold can be accurately controlled. High processing accuracy, smooth mold surface, and low friction between material and mold during the molding of electronic scale components, reducing wear. If the surface roughness is below Ra0.8 μ m, it can effectively reduce wear.
Heat treatment process: Reasonable heat treatment can optimize the structure of the mold, improve hardness and wear resistance. For example, by quenching and tempering the mold, its hardness can reach HRC50-60, effectively improving its wear resistance.
3. Operating environment and maintenance
Working environment: If the electronic scale mold works in a harsh environment, such as high humidity and corrosive media, the mold is prone to corrosion, rust, and accelerated wear. In a dry and clean environment, the wear rate slows down.
Daily maintenance: Regular cleaning, lubrication, and other maintenance work on the mold can effectively extend its wear life. If specialized mold cleaning agents are used to remove residual impurities and lubricants are applied to reduce friction, the wear resistance of the mold can be significantly improved.
Generally speaking, under normal use and maintenance, electronic scale molds made of mold steel and produced through good manufacturing processes can withstand the production of a certain batch of products and have good wear resistance. However, the specific performance may vary due to the combined effects of various factors mentioned above.
