SIG Corpoplast, a PET blow molding machine supplier in Hamburg, Germany, used its annual International Technical Conference in October to announce a new obstacle --

The company also announced a new comprehensive strike. and-
Filling lines and plans for sterile blow molding machines.
Corpoplast is part of the SIG drink, a new 11-month-

The group includes former Krupp blow molding company and SIG Simonazzi, a German and Italian company that provides filling, capping, labeling and cans-

Plasma coating technology for glass and plastic medicine bottles.
Plasma Pulse chemical vapor deposition of Schott HiCotec (PICVD)
Is adapting to use on PET bottles.
This process creates barriers to oxygen, carbon dioxide, moisture and chemicals.
The PICVD process has been used on mirrors, polycarbonate optical lenses and medicine bottles.
SIG aims to PET bottles for beer, other oxygen sensitive drinks and small carbonated soft drinksdrink bottles.
The PICVD process first deposits a transparent adhesive layer and then deposits colorless silica (SiOx)
Block layer 0. 01 to 0. 1 micron thick.
It is reported that the SiOx layer has increased the oxygen barrier of the bottle by more than 10 times ,[CO. sub. 2]
Klaus hajitz, technical director at SIG Corpoplast, said obstacles exceeded seven times.
He noted that these obstacles remained after hot filling or pasteurization.
He also said that this method is cheaper than other barrier technologies.
SIG expects the cost of Plasmax to be around $12 to $15/1000, which increases the production cost of uncoated PET bottles by less than 20%.
Bottles that allow the mold to make thinner can partially offset the cost of the barrier.
SIG and Schott HiCotec expect the SiOx coating to be FDA approved for PET bottles as it has been approved for other products.
SIG also expects SiOx-

SIG and Schott HiCotec are developing a 12-
Station rotating coating system for 100 cc to 1 liter bottle.
This Plasmax 12D Model will be two
Cavity machine capable of coating 0. 5-
Bottle for up to 10,000/hour.
It will be tested early next year and will go public in next September.
This process takes place in the vacuum chamber where the bottle is pressed below.
The gun inserted into the evacuation bottle is filled with a gas of six methyl disilicone.
Microwave is then produced to decompose the gas precursor, causing SiOx to deposit on the bottle. Byproducts--C02 and water--
Removed by the vacuum system.
This is described as a pulsed plasma system in which changing certain process variables changes the plasma gas from a gas with a viscosity to a gas with a barrier.

The Blomax Series III re-thermal stretch shows the latest details of the modular machine
Blow was first announced at k2001. in duseldorf and launched sales early this year.
In addition to having a modular \"plug\", these machines have a special linear heating oven that speeds up product replacementand-
Play \"blow stations that can be added or deleted as needed \".
At the meeting, SIG detailed the heating of the machine-improved premade rods due to higher temperatures
For longer thermal exposure, the spacing between the power lamp and the reduced core rod is 38mm.
Provides 50mm core rod spacing for heating premix with wider neck (36 to 49 mm).
Other improvements include the new cam-
Operating stretch bars to improve the distribution of bottle walls.
Other features allow 9% faster crystals and looseness, 7% cooling more effectively by \"flushing\" the air, and 50% opening the mold faster through the new CAM design.
SIG Corpoplast released Blomax 16E for 16-16
Cavity unit, this is the first one for heat-fill-able bottles.
It has a new mold design for improved heating.
The mold housing is heated to 320 F and the base mold is heated to 176 F.
After blowing the bottle, the blowing pin provides cold air to speed up the cooling.
There are already three orders on books from the United States. S. molder.
SIG Corpoplast recently added a smaller Blomax III model with four, six and eight cavities to a larger model with up to 20 mold stations.
The company is expected to launch 24-in 2003-and 28-
Station model, later a 20-
Double chamber station unit.
The estimated output was 36,000 bottles, 42,000 bottles and 52,500 bottles/hour, respectively.
The Brazilian plant at SIG Corpoplast has developed the smallest unit on the Blomax production line.
The new Blomax XT series comes with one, two or three cavities.
Blomax 3 T can produce 2L bottles at speeds of up to 1200 bottles/hour/cavity in three cavities, while 2 t can be at 900-
1000 bottles/hour/cavity.
The largest bottle, 8 liters, can be shaped in a single cavity at a speed of up to 850/hour on Blomax 1 t. These lower-

The new unit will be available at the same price as the Series II.
SIG corpocast also announced the development of its Premax PET pre-formed Injection Molding system.

From 5 to 2L, there are a wide range of standard arrangements for blowing, filling valves and capping heads.
Simonazzi is also developing a new aseptic blow molding system called Ecoshield ess.
It will perform filling and capping operations under pressure.
The machine will be available next year.
