Ceramic injection ram is a key component in the die - casting process. It adopts a core structure of alloy punch + nano - ceramic film, and is combined with annular friction grooves and metal friction rings, achieving both structural support and wear control.
The product features include: the surface ceramic wear - resistant layer has a hardness of 50±2 degrees, and its service life is better than that of ordinary ductile iron plungers; the silicon carbide material can withstand high - temperature environments, with a low thermal expansion coefficient of 4.0×10⁻⁶/℃ and good thermal shock resistance; it can dynamically form a lubricating layer, which is suitable for various working environments.
It is suitable for the die - casting production of aluminum alloys and magnesium alloys. It can be stably applied in scenarios such as precision machining, high - temperature forming and semiconductor packaging, helping to reduce the number of shutdowns for part replacement and lower production - related costs.
