Xaloy meets needs for precise on-off control of the injection molding melt stream with System Eng® needle shut-off nozzles.
* Controlled, process-dependent shut-off
* Shorter cycles than open-nozzle systems
* Minimal pressure loss
* No drool
* Optimal heat transfer
* No melt shear
Two types are available: the power-operated L series (at left in the photo above) and the spring-operated S-series (at right).

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.

The steady origin of new materials and resins leads us to the continuous research of more and more evolved technologies; the nozzles produced by Asso s.r.l., thanks to larger and larger investments, go from the simple small-dimension casting point to hand-manufactured articles in bimaterial, or to the pneumatic locking.
Nozzles are designed with cad-cam evolved systems, realized by numeric check machines and tested in metrologic rooms furnished with tridimensional machines always under numeric check.

Nozzles
The wideness of range of EMP nozzles comes from 28 years of active presence in the field of Hot Runner moulding.
More than 20 typologies of nozzles (Models), divided into more than 100 dimensional cathegories (series), available in the different standard lengths as well as in special executions, in function of the specific application needs, allow:
• freedom in planning, with a broad choice of methods of injection
• reliable performances
• uniformity and precision in temperature control
• as well as the processing of all main thermoplastics and elastomers
