Support pin


The support pin, in high-strength steel, is fixed inside the plunger tip with a thread or by a locking blocks system. The thread locking is attained through the contact between the head of the support with the inner part of the plunger head, to support the plunger itself during the shots. Instead, the locking blocks are inserted into their specific seats on the plunger tip and support. Holes and channels realized on the support body, belong to the cooling circuit.


Spacer is adopted as support for plunger tip to assemble with the Plunger Rod. It is suggested for small diameters to the maximum dimension of Ø70mm


Support pin is assembled with the plunger rod and fixed into the plunger tip. The head is in contact with the internal wall of piston and it does support the pressure of injection. Support pin contains inside special channels for cooling circuit
