Moulds for the Carbo Classic Base in Ultravent design
The requisite blow moulding pressure is one of the most important cost factors involved in producing PET bottles in a stretch blow moulding process. This issue is a highly complex one. In some cases, however, the limiting factor for reducing the blow moulding pressure is not the bottle design, nor the bottle specification that has to be met, nor the PET material type, but the inadequate venting.
With the experience gained from more than 1,000 blow moulding trials a year, Krones has enhanced the venting function for CSD bases. Here, 100 per cent venting and a very low blow moulding pressure for each application have been achieved.
The "Ultravent" design for the Carbo Classic Base is being supplied as standard for orders as from September 2015.
