Send to KindleOil packer's ink-jets add bar codes
Five lines to seven
These two expansions are also why the project with FoxJet just keeps growing. Some new ink-jet equipment was ordered just late last year. The original order covered five separate packaging lines and Amalie is now in the process of spending $1.5 million for two new packaging lines in its main plant. When the chemical packaging plant is completed two new packaging lines will be added there.
Even before the Amalie acquisition the company had acquired the rights to Engine Armor automotive products. These gas treatments and additives are more hazardous than filling motor oil so Petroleum Packers/Amalie decided to move their production and packaging out of the main packaging plant and into a totally separate building.
"Motor oil has a high flash point so it's not very dangerous to handle" Clarke says. "But the Engine Armor products are a different breed and they're very flammable. That's why we want to get those products out of our primary plant and into their own building."
Standardizing on equipment
Amalie has a well-earned reputation as a lean low-cost packager. Contributing to that Clarke says is its established practice of standardizing on suppliers.
"For us single-sourcing is very important" Clarke states. "We try to standardize on our suppliers and their equipment as much as possible. For example we use only one type of PLC on our equipment one type of pneumatic valve and now one supplier for ink-jet printers. This minimizes and simplifies training for the people here who will operate and work on the equipment.
"It also provides other benefits like eliminating the chance of finger-pointing to rectify a problem and it gives us the chance to work with the same set of technicians on all installations and service. That's really helped us to learn more about this equipment. And the ability to inventory fewer spare parts is a definite plus."
Amalie's relationship with FoxJet is definitely a partnership Clarke says. Because most of the equipment the company buys is customized to some extent Amalie needs to have a good close relationship with the company it buys from. That can be especially true in integrating software or in fully developing network capabilities. This was a significant factor in the original selection of FoxJet. In the face of the expansion after the Amalie acquisition it's become even more critical (see sidebar p. 51).
Other benefits
One of the major improvements expected with the shift to piezoelectric-operated ink-jet printers was a reduction in maintenance compared to the former CIJ printers. Unfortunately it hasn't been simple to compute Amalie says.
Chip Clarke is very clear about maintenance reductions. "Yes without a doubt this installation has definitely cut down on our maintenance needs. Some of this has to do with the improved technology. But because of the expansion we're still in the implementation stages of this project. Even now the new printers have cut down on our set-up times and they're pretty user-friendly."
But he says rapid company expansion has made it difficult to do comparisons either for maintenance or for economics. "We planned to track it carefully but along came the acquisition of Amalie. Our business and volumes grew so much we were lucky to fill orders much less study our costs. And our production volumes are so much higher now there's no way we can compare costs."
Preliminary tests showed considerable efficiency in ink consumption. But because production comparisons are no longer valid Amalie can't quantify reductions in consumption of ink. "At the very beginning we ran tests that showed considerable reduction in ink usage" Clarke says. "But keep in mind we're doing printing with these new systems that we couldn't even envision doing before. That's particularly true in our case printing with graphics and bar codes. Before all we could do was a one- or two-line message using alphanumerics."
Eliminating solvents
Another major benefit of the new ink-jet systems was their use of wax-based inks instead of solvent-based inks. "The switch to a system that doesn't use hazardous waste was a big issue for us" Clarke confirms. "We had been using a system that employed MEK-based inks and this was becoming a concern to us." MEK is methyl-ethyl-ketone a highly regulated solvent.
Because it recognized that it would need high-resolution printers for shipping cases the company sought other options for bottle marking. Clarke confirms his team evaluated laser printing and other scenarios that would eliminate solvent-based inks.
"We looked at other options and we even went so far as having samples produced to show to our customers. But we just couldn't compute a good return on our investment" says Clarke. "Plus they didn't offer all the functionality that we now have with these ink-jet systems. And at the same time we avoid the problems of handling solvents. This was huge for us."
Wax-based inks are also quicker to dry on bottles. In the past the company had to position the print area on bottles to minimize the chance of smudging or smearing the ink before it dried. In fact the plant had to provide sufficient accumulation space ahead of the case packer to ensure the codes would dry before collating and packing into shippers. The wax-based ink pretty much eliminates that worry says Clarke.
Improved print is the prize
After several months of experience with the new ink-jet printers Amalie has had excellent customer response from customers about the improved print quality.
"Some customers have commented on the readability of the tracking codes on bottles" Clarke says with satisfaction. "In the past they were sometimes hard to read. And occasionally we couldn't accommodate a customer's request for a production code. We were filling some bottles that didn't permit us to print a code with our former equipment.
"Just as important the new printing has generated new enthusiasm from our sales force. They use it as a competitive advantage compared to other private-label packagers."
