Anonymous users2024-02-04It refers to the German Grietz mold steel, a plastic mold steel material.
Basic information: Chinese name material origin Germany Glitz steel mill material properties plastic mold steel material name Germany Glitz mold steel.
Material name: German Grieze die steel.
Material properties: plastic mold steel material.
Factory condition. Annealing hardness up to 285HB
Main characteristics: the steel has good wear resistance, high toughness, high hardness, high compressive strength, excellent dimensional stability, excellent corrosion resistance, good polishing and cutting performance, and easy to achieve mirror effect. Excellent hardenability, air-cooled hardening, excellent machinability.
Main application: a heavy-duty and high-toughness impression impression.
First, high-stress injection molds are required.
A heavy-duty cold work tool.
Everything sharpens tools.
First, a plastic mold with high hardness and high toughness is required.
Machining and polishing. Under normal conditions (without potions), the brightness of this steel can reach 90%.
The polishing process is as follows:
1.Polishing the surface with stone strips (from coarse to fine) as follows:
2.Sandpaper (coarse to fine) sand the surface as follows:
3.Polished directly with 1 diamond paste.
The above processes have basically reached the mirror effect after all the above processes have been done, if you find that some part of the effect is not ideal, you can redo it once according to the above process, and the problem will be solved.
Note: Sanding sandpaper needs to be repeated twice with the cross method.
Due to the high cleanliness of the steel and the homogeneity of the material, the polishing performance is superior and can achieve a high degree of mirror finishing.
Note: The pressure should not be too much when applying during polishing, so as not to cause surface defects.

Anonymous users2024-01-28Die steel contains chromium and tungsten elements that are easy to form carbide, so it has high strength and hardness at high temperatures, with a hardness of 300HB at 650, but its toughness and plasticity are more tolerant. It is commonly used in large top forging dies, hot pressing dies and flat forging machine dies that require high hardness and high wear resistance, with high disguised temperature and good heat fatigue resistance to cold and hot alternating resistance.
The material is closest to JIS standard SKD5 mold steel, VDEH standard X30WCRV53 mold steel, and ASTM standard and AISI standard H21 mold steel.
The ratio of gold to elements is approximately: carbon, silicon: manganese: chromium, tungsten.

Equivalent to domestic grade: 5CrNi4Mo
The chemical composition is shown below:
In the past, there was no special plastic mold steel in China, and the general plastic mold was manufactured with normalized 45 and 40cr after quenching and tempering, so the mold hardness is low, the wear resistance is poor, the surface roughness value is high, the appearance quality of the processed plastic products is poor, and the service life of the mold is low; Precision plastic molds and high-hardness plastic molds are made of CRWMO, CR12MOV and other alloy tool steels, which not only have poor machining performance, but also are difficult to process complex cavities, and cannot solve the problem of heat treatment deformation. As a result, the steel for special plastic molds has been developed in China, and certain progress has been made. China has its own special die steel series, has been included in the national standards of two kinds, namely 3cr2mo and 3cr2mnnimo, into the industry standard has more than 20 kinds, has been promoted and applied in the production of more than 10 kinds of new plastic mold steel, the initial formation of China's plastic mold steel system. >>>More
