Inserts - Import export

During the aluminum casting process, the metal melt is either poured or pressed into the mold. This process is used, for example, to manufacture cylinder heads, wheel rims and many other aluminum castings. Here, the mold has to repeatedly withstand the metal melt at a temperature of over 600 °C: for inserts made of our tungsten-heavy metal alloy Densimet® and the molybdenum alloy TZM, that's not a problem. The benefits to you: — Shorter cycle times — Top surface quality for your products — Long mold service life — No cracks in the mold insert Tailor-made mold inserts, sprue bushes, cooling inserts and other individual parts as well as semi-finished products for your mold are available.

Molybdenum-hafnium carbide (MHC) is highly temperature-resistant, has a high level of thermal conductivity, a low coefficient of thermal expansion and a high recrystallization temperature. MHC retains its shape even when used at temperatures of up to 1 550 °C. At temperatures up to 800 °C, MHC is suitable for use in die inserts. At higher temperatures, the producer recommends using MHC for full dies. The benefits to you for a long service life: — Optimum nondeformability and dimensional stability — Low tendency to crack in the case of edged profiles — High thermal stability — High thermal conductivity — Low thermal expansion — Good hot ductility — Very high recrystallization temperature Plansee supplies MHC components in disc form with or without drilled start hole.
