Injection systems are equipped with heating elements - electrical resistances - that function with electric
current.
The use of electricity requires several care. Negligence to use proper safety procedures
against electrical risks can cause fatal or irrecoverable damage.
YUDO is not responsible for damages caused by negligence or failure to comply with appropriate safety
procedures.
If you have questions about any security procedure in systems installation and handling, please contact

1.1. S AFETY P ROCEDURES
During handling and Hot Runner System operation, high temperature and high pressure injection are used.
In order to protect the operator in the workplace, it is important to ensure that all safety devices are installed in
equipment as follows:
- Warning Labels placed in the mold and machine;
- Reference to the machine user manual for safety procedures and checks when they are not internally
defined.
- Adequate individual protection equipment must be used to protect individual against high temperature
surfaces, gases or liquids expelling, falls and cuts.
- To avoid serious burns wear protective clothing heat resistant, heat resistant gloves and face protection,
including safety goggles. Use adequate ventilation for fumes.
- Contact with hot nozzle can cause severe burns. Use signs in a visible place stating "DANGER"
- Before performing any electrical work, check the Hot Runner System is properly connected to the earth.
Failure to do so can result in a serious injury or death.
- All electrical power and thermocouple cables must be secured to prevent damage during assembly.
The power and Thermo collective sockets should not have direct contact with the mold.
It must be ensured an adequate connection of the Hot Runner System to earth.
- The operator shall ensure that, before system startup, it must be earthed or protected by equivalent security
measures. In case of mains connection in different systems, or system components of normal operation
specified, must be ensured proper grounding or other security measures equivalent to each component.
ATTENTION : Normally, the system is designed for a 2000 bar injection pressure
