Neck ring lubricants

Glassline neck ring lubricants are designed to be consistent and stable.

We do not recommend mixing blank mould lubricants with other oils.

Neck ring lubricants are in general lower in viscosity as the rings requires less lubrication. Using blank mould dopes or mixed products will result in build up of carbon between the guide plate and ring, as clearances are narrow.

Using specific neck ring lubricants will avoid distorted finish and sticking of guide rings.

Reducing oil viscosity can also lead to over-lubrication or splashing on the plunger.

Glassline neck ring lubricants are widely used over years in typical applications covering a wide variety of ware such as wine, beer, cosmetic and pharmaceutical ware.
