Bellignat, France-based Billion SAS will take delivery soon of an 800-ton GM model press to conduct product trials for customers that want to use more recycled material.
The injection molding machine builder is installing one of its own mid-range presses at its technical center in Oyonnax, France, to meet demand for tests of products that have a layer of post-industrial or post-consumer material sandwiched between layers of virgin material to meet corporate sustainability goals.
"A lot of times the cosmetic and packaging industries want a nice surface outside and to say they used X amount of recycled material," Billion General Director Georg Kiesl said at Fakuma 2023. "With this process, they can use 40 percent regrind, but on the outside, you can't tell."
Until recently, about 20 percent of mold trials were done for projects involving sandwich layers. Now it's probably 80 percent, Kiesl said.
"We've added the 800-ton machine in our technical center to do trials on big parts, with regrind that mainly comes out of construction, like floor tiles and roofing tiles. There's been a big increase in trial demand," Kiesl said.
For the sandwich technology, Billion's presses are equipped with a special nozzle designed to produce extra-thin walls to 0.7 millimeters.
"We've run applications in competition with other molders," Kiesl said. "Some big customers have come in and tried molds throughout town. Then, they came back to us and said we're able to have the highest amount of regrind inside."
