ZLeak Tube® is a pre-formed aluminum pipe with special filler materials. It can sustain its own shape as original from the high pressure and high temperature of HPDC.

The inserting ZLeak Tube® HPDC process can finish the casting process simply onetime. The fillers in the tube are easily and clearly removed after casting, and the empty tube becomes water coolant channel.

The single HPDC process with ZLeak Tube® provides lower cost, shorter production time and no more leakage failure mode. It has no more particles in the channel unlike sand-core casting.
