boss consults, stamped aluminum profile, material thickness below 1 mm. Now the mold core is made of DC53. The hardness is unclear and the mold core will crack. I want to ask which mold steel is good?
The boss's mold core is similar to our railway bridge. It is the base below and there is a raised rib strip in the middle, which is a thin-walled mold, and the thin-walled middle is hollowed out. Observe the wear marks, the mold should work like this: the raised rib strips are used to locate aluminum, and punch holes are made in the hollowed-out area. The cracking place is around this hollowed-out area, and the entire thin wall collapses.
Similar thin-wall mold cores, Yuhui Mold Steel Huang Zipeng believes that using LG Mold Steel is a good choice. A while ago, there was a boss's mold that looked like a bayonet. The front end was a long strip with a wall thickness of about 15 mm. The strip was very long and the front end was under great pressure. It turned out that high-speed steel was easy to break. Later, the LG mold steel was effective and the mold had been opened twice.
LG mold steel has a toughness of 8-9 times that of DC53. The mold is tough enough and will not break even if it is bent. The hardness is HRC54-58, which has high strength, so you don’t have to worry about deformation. LG mold steel is an electroslag remelting + forging process steel with good tissue density and good fatigue resistance. It is very effective for workpieces that require repeated stress and cannot break.
. Yuhui Mold Steel Huang Zipeng recommends using 8566 mold steel, with hardness HRC58-60, and toughness 4 times that of high-speed steel SKH-9 and 2 times that of D2. It is made of stainless steel buckle cold extrusion molds with a high stress, and the lifespan is twice that of D2. It can meet the requirements of high-strength and high toughness of high load mold conditions.
The boss in front of the screen, if there is a similar working condition, you can also try it from Yuhui Mold Steel Huang Zipeng.
