Meccanoplastica will be taking two completely electric blowing machines to K 2016: the single-station HL 750/S for continuous extrusion blow moulding, and the single cavity MIPET-1GM for the stretch blow moulding of PET preforms.
The first, designed to produce containers with capacities of up to 30 liters, features a clamping force of 30 tons and a 750 mm horizontal stroke of the mould carriage. The HL 750/S stands out for its electromechanical mould clamping system, which is driven by a brushless motor, and for its hydraulic bearing with 2.2 kW motor multiplying the clamping force. Added to this, it offers the possibility of recovering the electrical energy in the motor braking phases of the moving mechanical parts (mould and mould carriage).
The machine that will be on display at the fair features a one-way extruder head and single-cavity mould for producing, at an output rate of 80-85 units per hour, PE jerry cans of average molecular weight with a capacity of 20 litres and a weight of around 800 g.
The MIPET-1GM is designed to meet the flexibility needs of processors as it is able to produce PET containers with capacities of up to 10 litres, in the single-cavity mould configuration, and containers with capacities of up to 2 litres in the two-cavity configuration with a centre distance of 130 mm. This machine is notable for its holding pressure (10 bar) equal to 450 kg, maximum mould opening stroke of 210 mm, and high cycle rates, attributable to the immediate feedback of the fully-electric command system. This machine is manufactured at the Barcelona facilities and is an absolute first for Meccanoplastica.
At the fair it will be set up with one- and two-cavity moulds to produce PET preforms for bottles having a capacity of 500 ml and weighing 30 g, with a round and square base respectively, at an hourly output rate of 2000 bottles (with the 2-cavity mould).
