“BDF D.A.C.” DUAL AXIAL COOLING
“BDF D.A.C.”
Mechanical Features • Independent on/off valves for mould cooling and neck-ring cooling • “Total air flow passage” on/off valves series 300 • Air feed to the mould trough telescopic piping, spheric joint and plenum chamber close to the moulds • Use of different plenum chambers depending by the mould diameters • Plenum chamber fast change design • Plenum chamber for axial cooling or stack-cooling mould design • Use of standard mould holders and mould assemblies
Main Features
• UNIFORM HEAT DISTRIBUTION ON THE INTERNAL Mould SURFACE • CONSTANT COOLING CONDITIONS • EQUAL COOLING CONDITION IN THE TWO CAVITIES OF THE Mould (BETTER GLASS DISTRIBUTION) • MORE THAN 50% OF COOLING AIR SAVING COMPARED WITH THE STANDARD COOLING • POSSIBILITY OF 360° MOULD COOLING
• Mould cooling possibility: 1. From the side of the mould 2. From the bottom of the mould 3. With or without independent neck-ring cooling • Available for blank and blow mould cavities • Possibility to use moulds design for axial or stack cooling
