In the combined-type hot runner system,nozzle and manifold form a simple unit.The melt flow directly from the manifold into the nozzle , and will not produce deviation and flow blind horn.Through the thread nozzle to be embedded manifold and eliminating leakage phenomenon of the nozzle and manifold.
The traditional bushing system design will prodece the thermal expansion,and this combination of system is particularly effective in such leakage.
The combined-type hot runner located in the middle of the mould and have less connection with the mould.
Its manufacturing materials shouldn't have high thermal conductivity, also does not need the ground-clamp and to mould set of advance and tension. The minimum level of connection provides high precision and stable temperature curve, so the expenditure of energy than traditional hot runner system are much lower.

Combined-type hot runner system can directly with independent of the mould preinstalled hydraulic lines. Hydraulic equipment direct drive valve mouth may also directly to install on the system, so that replace the traditional machine control valves, make injection molding more flexible. In addition, electrical and hydraulic lines can also according to customer requirements for configuration. Because the system before delivery will experience electrical, temperature, hydraulic or pneumatic testing, so customers will get pre-installed system instructions, which can be easily in the mould for installation in and immediately put into production.

When mold or system needs to be general maintenance, combined-type hot runner system can be also used simple steps removed from the mould, which can be independent of mold repair and testing.
Usually, combined-type hot runner system reduces the maintenance cost. The complete hot runner system based on the prepared design and installation, assembly process in heater or thermocouple wire be removed. Connect heater and distribution box wires was placed in a special design of the tube, the mold or the removal of hot runner system is very favorable. At the same time, comprehensive hot runner system can be removed from the daily maintenance, and save the time and reduce the incidence of the assembly error.
