Service and Maintenance / Single Axis Valve Gate Nozzle 16SVH

Safety Instructions for the Service at the Single Axis Valve Gate Nozzle 16SVH

Hot Surfaces Hazard

Contact between the skin and hot surfaces could result in burns.

Use personal protective equipment, such as gloves, apron, sleeves and face

protection, to guard against burns.

When servicing or handling the hot runner system outside the manifold plates

or the injection molding machine, care must be taken to heed the hot surface

exposure warnings.

For rst aid contact your medical / safety representing.

Hazard of Pressurized Air

Pressurized air blow can result in hot plastic or foreign bodies entering the

eyes, causing vision damage.

Following work must be carried out by qualied and experienced persons.

Use personal protective equipment: Face protection, hearing protection and

gloves.

NOTICE

Hazard of Material Damage

Without consulting Synventive it is not permitted to do modications to the

hot runner system e.g. geometrical changes to the nozzle tip, except the part

shape adjustment in the area of material allowance.

Any impact against the nozzle tip may result in its damage.

Never hammer or impact the nozzle tip from the front (i.e. from the side of the mold).

Twisting could damage the nozzle tip.

When replacing the nozzles, the sealing rings must always be replaced.
