Method for manufacturing a glass container having a large impact strength using permanent and non permanent coatings on the apparatus

A method for manufacturing a glass container comprising the steps of:

• providing a plunger having a first portion for forming a mouth portion of a parison and a remaining second portion, the first portion of the plunger being coated with a sprayed metal coating of self-fluxing alloy having a hardness less than Vickers hardness 800 and the second portion being coated with a ceramic coating;
• forming a lubrication carbon layer on surfaces of molds including a blank mold and a neck ring by periodically injecting flames of gaseous hydrocarbon having a carbon to hydrogen ratio more than 0.75;
• supplying a gobbet of glass to the blank mold;
• producing the parison from the gobbet of glass, using the plunger, the blank mold and the neck ring;
• and
• blow-forming the parison to a glass container of a final configuration.
