Hot runner employs PID controlling system which features
automatic compensation and automatic protection, and contrib-utes
to the prolongation of lifetime of electric heater;
The precision of temperature controlling falling within1℃,
which ensures to avoid plastic in the hot runner being
burnt, resulting in a yield of up to 99% and more;
Ultra nozzles are designed to be maintenance-friendly.
Nozzle tip inserts, heaters, tip insulator, and thermocouples
are easily accessible and can be replaced while the hot
runner is mounted in the machine, which minimizes down-time
and reduces mainte- nance cost.
The material of core and cavity in mold is top
material. All the parts are processed on CNC machine
tool with high precision, especially the plate,
the error is than 0.05mm.
All parts are treated by heat treatment strictly,
to ensure their intension and life time good enough.
After the treatment, the intensive neck ring and
core hardness can be HRC48~52, the hardness of
cavity can be HRC44~48.
