The unitized system offers considerable improvements in quality and addresses the cost of repair favorably. Since the integrated system is based upon using the unitized prewired design for installation in the mold, the chance for pinched or severed heater and thermocouple wires is eliminated during assembly.

All wiring from the heater to the junction box is encased within a conduit specially designed for that purpose. This is always a benefit whenever the mold/hot runner system is disassembled. Also, since the unitized manifold system is fully functional before being installed in the mold, full testing of electrical and thermal functions are performed at the factory before shipment.
An integrated hot runner system further provides the injection molder the added benefits of the following:

1) Routine maintenance, which can be performed without removing the hot runner system from the molding machine. While conventional injection halves also allow some maintenance to be performed when in the molding machine, it is limited to the very front of the nozzle area due to the retainer plate. Servicing beyond this point requires the hot runner manifold system to be removed from the machine in order to expose the manifold system.

2) Simple hot runner system/mold interchangeability. Inserts can easily be interchanged without mold removal.

3) Valve gate operational plumbing, which can be serviced without disassembly.
Additionally, all of the following operations can now be performed without removing the integrated system from the injection molding machine:

1) Gate tip exchange

2) End cap exchange

3) Nozzle heater exchange

4) Nozzle thermocouple exchange

5) Manifold thermocouple exchange

6) Complete hot runner inspection
Incorporating the integrated design involves preliminary review with the mold manufacturer to ensure proper operation. The unitized hot runner manifold is mounted directly to the top plate of the mold

  Since the hot runner system remains firmly attached to the stationary plate during this work, the mold can be repositioned again immediately after the service work is complete and can be ready for production again in just a few minutes. Integrated systems can thus save several hours-or in large systems perhaps days-during routine hot runner system maintenance.
Unitized systems provide a considerable contribution to reducing the number of errors and saving time for mold manufacturers during the manufacturing and sampling of new molds. In addition, integrated systems permit additional savings for injection molders by reducing downtime during injection molding production.
