Castool Tooling Systems – Die Cast Toolings (Ring Plunger Tip System)

The plunger tip is a critical element of aluminum die casting process. Its’ successful operation depends on a number of factors. The most important factor is its’ efficient interaction with a round, straight, thermally and therefore dimensionally stable shot sleeve. Castool’s plunger tips were developed a number of years ago by Allper of Switzerland. The plunger materials have been developed jointly between Allper and SCHMELZMETALL over the last 30 years particularly for die-casting. All the copper alloys are refined from virgin materials, heated and casted in high vacuum to avoid oxides, forged and thermally precipitated. The alloy combines high fatigue, high hardness, high resistance to heat and high thermal conductivity.
