Plunger Tips

• Uniform structure and high thermal conductivity of AMPCOLOY® materials add significant value to this process.

Water-cooled, copper-alloy plunger tips are used to push molten zinc and aluminium through a polished steel sleeve and into die cavities to form intricate parts. The inside diameter of the steel sleeve and the outside diameter of the plunger tip are machined and polished to best match tolerances, with clearances of 0.05-0.13 mm.
