A:A: Current heat treatment processes do not reflect this difference.
A:A: Because if the hardness is the same, wear will occur simultaneously. The lower platen hardness protects the mold frame, reducing the cost of replacing the platen. Also, after a period of use, the mold frame's internal cavity will expand. When replacing the platen, a larger platen can be used to eliminate burrs.
A: The current hardness standard (production standard: 58-62 HRC) has not been adjusted by German heat treatment furnace engineers. It depends on the material itself.
A:A: We use Hardox plate for the suspension plates of hollow bricks, which is suitable for every series. Some special-shaped suspension plates use 45cr tempered steel.
A:Answer: German and Chinese boards are suitable for all brick types. Hengda 500 is suitable for 913 hollow bricks and some solid bricks. Hengda 600 is used for some curbstones. Currently, Handa 500 is the preferred choice.
A: Yield strength: 345 MPa. Wear-resistant plate is used for the flat hollow brick pressure plate, ZN900CG with positioning grooves, and Handa plate is used where the POYATAS contacts the main machine.
