Mould cores and cavities
Prehardened steel for very large-size moulds and tools with high hardness and structure homogeneity through the block and improved texturing properties. Reliable repair welding and high thermal conductivity.
For which tool
Plastic injection mould cores and cavities, large-size moulds for bumpers, dashboards, television panels, etc.
For which plastic
Thermoplastics (PE, PP, PS), thermosetting plastics, transparent melts, ABS
Typical values (weight%).
Superplast® 2738 mod. Premium is delivered quenched and tempered to 290 – 330 HB (30 – 35 HRC) or 330-370 HB (35-39 HRC).
|Hardness||Rp 0.2 Yield strength||Rm Tensile strength||Elongation||Reduction of area||KCV 20°C||Elastic modulus|
Typical values – thickness 400 mm – quenched and tempered
Thanks to a specific solidification process, Superplast® Premium steels exhibit a high homogeneity in both hardness and metallurgical structure (bainite + martensite) through the whole block, up to 1300 mm thickness. This aims at improved and reproducible performances in polishing, texturing and global surface aspect.
Thanks to the absence of segregation, texturing is not limited to easy patterns anymore. SP Premium is suitable for geometrical and other complicated patterns (logos for instance).
Polishing is guaranteed up to SPI A2 (3-6μm, mirror polishing).
Apparition of orange peel or waves is limited thanks to the absence of segregation.
Typical delivery sizes
|200-610 mm||1000-2100 mm|
