* Chris Robinson, director of quality assurance at Bowling Green, said maintaining the wall thickness required for the neck, shoulders, walls and bottom of PET bottles is an ongoing challenge for blow molding machines, Ohio, southeast container plant (SEC)Group Inc.
\"The problem with most bottles is related to the thickness,\" Robinson said . \".
Choke neck, Pearl feet, or thin side walls are common problems.
\"There are several variables in the blowing bottle, including the quality resin, mass and machine group of hot, humidity premade rods --

In order to control all of these variables, molder needs to be real

Carry out production line inspection of sample bottles produced every hour.
The SEC cut the bottle and weighed it as an indirect measure of wall thickness.
This method does not allow timely adjustment of the Sidel re-heat stretch of SEC.
Each bottle blowing machine can produce tens of thousands of bottles per hour. \"Any bottle-
\"Quality problems can affect production for an entire hour,\" Robinson said . \".

Coke bottles, the consistency of the product is crucial.

The device uses two infrared sensors at each discharge to measure the two points on the bottle.
With only one discharge, PETWall can hold four sensors, four thickness readings per bottle.
Take the reading within 0.
2 seconds or less, so the device can handle up to 30,000 bottles/br per discharge.
The accuracy of the measurement is said to be 0. 001 in.
\"The device can identify the process trend before the process trend becomes a production problem, shorten the detection reaction time, determine the cause, and adjust the blow molding device to solve the problem,\" Robinson said . \".
The operator uses the reading of PETWall to adjust the heating area in the molding machine.
The system has been commercial since then, and the price is below $75,000 depending on the system settingsup. Real-
The time detection consists of an infrared plate and a cylindrical sensing head.

Thickness measurements within the preset upper and lower limits control range are shown as green.
Yellow indicates a wall thickness that is not very good but still acceptable, and red indicates an unacceptable wall thickness.
In this way, the operator can quickly and intuitively display wall thickness readings from each sensor.
The operator immediately knows when to adjust the heating area and immediately sees the results of these process changes.
PETWall also offers
Control the minute average chart for the upper and lower limits so that the operator can see if the process is out of control.
\"This is where the system goes beyond checking and sorting out bad bottles, giving the operator enough product information that is relevant to what is happening inside the blow molding unit,\" said Atkinson . \".
Robinson noted that the SEC also conducts a visual inspection of bottle defects and contamination at least once an hour.
Since July, the SEC has installed PETWall systems on its machinesliter bottles.
The SEC produced clear and green packaging at the bank and found that there was no difference in the color of the bottle.
The company is now setting up PETWall on the second line, which will make 20-az bottles.
