Externally heated sprue nozzle for injection molding machine Thermoplay

The progenitor range of the D nozzles has been completely renovated to meet the continual demands of the customers, who need more flexibilityand easier application in mould hot runner systems.
The nozzle tip assembly, which was integrated into the old nozzle body, is now screwed into the core.
Besides facilitating maintenance operationson the open moulding machine, there is also an economic saving on spare parts.
The first types of D nozzles available with the screwed tip are types1, 1B and 3B.
All the tip types are constructed with a special sintered steel, which has an optimal thermal conduction, and makes them much more resistant and not subject to wear, therefore they are suitable for the injection of all types of thermoplastic materials.
Also, the diameter of the channel inside the nozzle core has been increased, to improve the flow rate and for easier injection of large size parts. For easier application in moulds with many cavities it has been decided to increase the thickness of the D nozzle heads, to have more space for the outlet cables and as a consequence be able to increase the number of hot half injection points obtainable with D nozzles.
