Closure Business Update
We have a unique perspective from our days in manufacturing molds. Our past has given us a great appreciation for what it takes to achieve good part quality.
Together with colorant this makes 70% of the total cost
Followed by the energy
It is obvious that the best thing that a closure manufacture can do to optimize the cost’s, is to work on lighter design and faster cycle in order to improve output with the same investment.
Looking at the raw material cost’s the financial guy of your company will of course look first for a cheaper raw material, most of the time has ended in a disaster. Big bottlers therefore have established a list of approved raw materials and the prices in this range does not differ too much.
The investments for a closure production is very high but the margin for closures in the soft drink industry has shrunk to almost nothing. Today investing in this business makes only sense if caps are produced in the most efficient way and in high volumes.
I think this guy is not a cap producer, and in case he is one he must be carrying the money to the raw material supplier
Today I would like to walk you through the path the resin takes from its pellet form to the molten state where it is introduced into the mold cavity. Specifically, I will discuss this in the context of beverage closures. You have heard much discussion about the technology the resin and additive suppliers have put into their products – I’d like to show you the conditions they are subjected to in the molding process. Also, I hope to show you some of the important considerations that are made to maximize the processing window even with the tremendous performance pressures in the market today. As such the most relevant trends are…..
PCO standard with 21mm height
Owens Illinois with , this is the only newer neck which is already available in the market in Belgium on a litre Coke bottle
PCO 19 which is an interesting Neck finish. This Neck was already developed and introduced several years ago in the Italian market. So far nobody has really noticed this neck which was almost 1 gram lighter than the BPF or Alcoa neck at that time.
Bericap Shorty, as far as I know this neck is only in design stage now
Alcoa short CSD is in line trials since long time now and introduced already in Latin America
PCO 1881 launched by the ISBT International Society of Beverage Technologists
PCO Corvaglia, This neck actually has been developed for the Italian market. There big bottlers like San Benedetto went one step to far and have used the Alaska 3-start neck for CSD products. Other small bottlers followed without thinking and this ended in a disaster. You can still find CSD products with this flat water neck in the Italian market. Our idea was to create a neck which is fully compatible with the 3-start Alaska neck. This means almost no changes on, blower, filler, capper and lowest cost for the conversion of a preform mould.
Finally the Sacmi ML27 which I believe is a innovative neck. The particular design of the new rim system to break the safety band with torsion and not by pulling the bridges is a good idea even if not new and already in the market in Switzerland since over 20 years. The two start thread is already in use in Italy since a few years but is disappearing again because of availability of preforms and closures. I also doubt that a two start thread is good enough for high carbonated soft drinks.
There are huge cost involved if somebody wants to convert a neck finish and I think it is a nightmare for every bottler who has to make such a decision. I have put together a few criteria's which are important for such a decision.
Supplementary Slide
To compliment the moving platen support, the stationary Reflex platen re-directs the tie bar reaction force towards the center of the platen reducing deflection.
While the conventional multi-link toggle clamp has a force flow path towards the perimeter of the platen allowing uneven force distribution.
Our approach provides lower tonnage, less mold wear, and better quality parts.
(doing mold test regularly in our tech centers demonstrating clamp force reductions up to 50%)
