Three-Layer Bottles with Auto Weight Control
All-electric machine produces three-layer bottles that are leak tested and weighed, with automatic feedback to adjust the process.
Kautex Machines is molding three-layer personal-care bottles on a KBB40D double-side shuttle, one of its latest series of all-electric machines. This unit has been sold to Amcor, which has representatives at the Kautex booth.
At NPE, Kautex is molding a 600-ml, flat oval bottle in 2 × 5 cavities. Leak testing is performed inside the machine, and continuous weight checking of the bottles feeds back to adjust the process automatically. The quick-mold-change features of the KBB are demonstrated twice a day.
The bottles use the three-layer ReCo process, whereby color is added only to the outer layer; the inner layer is virgin material; and the middle layer uses regrind or PCR (post-consumer recycled) plastic.
Kautex is also showing off the second generation of its “virtual machine,” a training tool that enables exact simulation of production on a KBS, KBB, or KCC series machine. In keeping with the Industry 4.0 “smart factory” trend, Kautex is also presenting remote diagnostics, called Kautex Remote Service.
And as with all sciences, there are fundamentals that must be considered to do color right. Here’s a helpful start.
