Maximum output levels
The PET-LINE 5000 was developed specifically for markets with extremely high output and it is designed for molds with 96 to 144 cavities. Reto Bamert, sales manager of the PET business unit, believes that its target markets are generally located outside of Europe, in particular in the U.S. and Asia. "High output levels are especially needed in these large beverage markets. Our customers there are generally large bottling plants that require a calculable number of bottle variations, but in such vast quantities that using a 144-cavity preform mold is justified. In these regions, our systems are horizontally integrated into the production process; we see, for example, our product lining up directly alongside a blow-molding machine."
Top energy efficiency
Just like the smaller models, the new PET-LINE offers several first-rate changes in the areas of energy consumption, control technology and machine control, such as an energy-efficient adaptive drive unit. It no longer operates with constant pump pressure, but rather adapts flexibly to the individual application and cycle requirements. In addition, all of the machine's electrical drive motors are interconnected via an intermediate circuit to allow the braking energy being generated during operation to be used elsewhere. All in all, the system reduces the power requirement by around 10 percent compared to the preceding model, with this figure increasing to up to 20 percent in comparison with the competition.
Highest speed increases daily output performance
The lock-to-lock time of the new PET-LINE 5000, from unlocking the mold to preform removal and locking, has been reduced by up to half a second! For standard applications with cycle times of less than 10 seconds, this equates to an increased output performance of tens of thousands of units per day! This was made possible by the new control technology: The exclusive use of digital controllers was combined with state-of-the-art valve technology. Shorter reaction times and increased oil displacement mean that the movement of the mold is swifter, while the dry cycle of the machine is reduced. The desire for speed is also embraced by the custom-developed robot, which can move dynamically into the mold even when it is not entirely open.
