1. MECHANICAL SYSTEM
Minimum Hydraulic Oil utilization for Mould clamping, working at a lower pressure 60/90 bar. Pump power 2/3 KW.
Mould Clamping Force Adjustable according to the container.
Consistency and Repeatability.
System to Raise the Needle Blower for Deep Bases.
2. ENERGY SAVING
At present, the reduction of energy consumption has become one of industry’s priorities.
Urola’s extrusión blowmolding technology is based on a rotary concept, which contributes in a very decisive way to the attainment of these objectives.
This technology allows 30-40% savings in energy consumption in relation to conventional systems.
The explanation is very simple:
The moulds are placed in a wheel, where the blow molding action takes place.
The moulds are opened mechanically by the actor of a cam.
It is therefore, a mere fact of maintaining the wheel moving, which needs a minimum energy to do so (4-7kw).
As they only have one head, the heating energy in relation to other multi-head systems, is also minimized.
We also apply the most advanced developments regarding the extrusion equipments used in our machines, which suppose a dramatic reduction of the energy consumption.
All of these factors together, allow us to obtain values as low as 250wh/kg, a “record” number in energy consumption of extrusion blowmolding equipment
