Plunger Tips

Mipalloy offers Machined Plunger Tips. These are used for die casting in Mipalloy-4, 2% beryllium copper material. Mipalloy-4 material has very high hardness in the range of 35-40 HRC. Its higher hardness gives higher service life for these tips. All plunger tips are accurately machined in-house in the advanced state-of-the-art CNC machine shop, which gives customers perfect, repeatable quality plunger tips. Mipalloy-4, 2% beryllium copper (C17200) plunger tips have set the standard for quality in the industry. Enhanced productivity, lower down times, and fewer tip problems, consistent performances are the hallmark of Mipalloy-4 plunger tips. The fine grain structure of Mipalloy-4 plunger tips with high hardness and thermal conductivity makes the tips more resistant to constant wear and punishment that takes place during service. For maximum service life and shot sleeve performance, 2% beryllium copper has no equal as a base alloy for plunger tips in aluminium die casting. Mipalloy-4, 2% beryllium copper plunger tips are harder and stronger than those of other alloys and manufacturers, providing longer shot tube life with a extra margin of safety and permitting closer tolerances when grinding to finished dimensions. Mipalloy has the capability to manufacture plunger tips in a wide variety of sizes from 1" diameter to 8" diameter. Standard sizes are typically 3" diameter to 5" diameter.
