Sacmi technology - Two more CBF for the Chinese dairy

MajorChinese company in the dairy sector purchases two more CBF (Compression BlowForming) systems, taking the total number of installed solutions to four.Highly innovative process combining high bottle quality with weight reductionproved to be a major plus factor.

These,then, are the distinctive characteristics of the CBF technology by Sacmi, whichhas now won over a leading firm on the Chinese dairy market, a company that’salready one of the world's top ten players in the industry. This latest orderdoubles the existing number of machines, taking the total number of currentlyinstalled CBF machines to four and making this customer one of the world'sbiggest users of Sacmi technology.

Thankslargely to Sacmi's ability to transfer the intrinsic advantages of compressiontechnology to another industry - plastic container production using thedifferent commercially available resins - the CBF platform aroused the interestof this key dairy player following the outcome of in-depth comparative analysiswith extrusion blow-moulding (EBM), still widely used for pasteurized productpackaging.

So what arethe competitive advantages of CBF? A cycle time of 7 seconds and,simultaneously, a container weight that - against an increase in quality -drops from 19 to about 15.5 grams.

Designed toproduce 200-ml HDPE containers, these CBF machines provide a weight reductionof about 20% - with related energy and raw material savings - and a consequentincrease in competitiveness. This goes hand in hand with the high consistencyand repeatability of the highly innovative CBF process, based on continuousextrusion of the plastic, which is then cut into doses of pre-determined size.The latter are then inserted in an open mould and compressed to make a preform.The result: a single technological platform that allows containers to be madedirectly from the pellet.

Atop-flight company, the customer does business with firms all over the worldand works with major US research bodies. This, then, is a strategic order forSacmi, essential to reinforcement of its international position on the dairymarket and, in parallel, development of further orders, not just with thistechnology but also other group-supplied beverage solutions such as CCMcompression presses for the manufacture of plastic caps and the new modularlabellers.

Thecustomer's investment decision was determined not just by the anticipated boostin productivity and the lower container weight, but also by the possibility ofachieving, via this technology, maximum process repeatability and a generalincrease in container quality. Additionally, the machine lifespan is longerthan that seen with alternative technologies and there are no internal sealingbeads which - among other things - means greater resistance to the hightemperatures and pressures typical of pasteurisation processes.
