Copper pistons are a critical component of the injection system in pressure die casting (HPDC) machines, pushing molten metal through the shot sleeve into the mold cavity under high pressure.

Plunger tip, metal:

• Moving at a controlled speed

• Minimizing turbulence

• Removing air from the system

• Ensuring homogeneous filling.

makes it possible.

Why Copper?

Copper alloys are preferred because:

• 🔹 Provides high thermal conductivity.

• 🔹 It reduces sticking by dissipating heat quickly.

• 🔹 Resistant to thermal shocks.

• 🔹 Minimizes shot sleeve wear.

• 🔹 Reduces metal spatter and soldering.

Bu sayede daha stabil enjeksiyon ve daha düşük porozite elde edilir.

Impact on the Process

Correct plunger tip usage:

• Less gas porosity

• More even filling

• Reduced waste rate

• Long shot sleeve life

• More stable cycle time
