- Output: more than 100,000 preforms per hour
- Previous “lock-to-lock” time reduced by up to 500 milliseconds
- Netstal at #NPE205
Netstal has introduced the PET-Line 5000 to the US market. The preform production system is designed for molds with 96 to 144 cavities and was developed specifically for markets with extremely high output.
Maximum output levels for the US and Asia
According to the company, high output levels are especially required in the US and Asia where the employment of 144-cavity preform molds is appropriate. Netstal’s customers are generally large bottling plants that require a calculable number of bottle variations. In these regions, the systems are horizontally integrated into the production process, for example, the product lining up directly alongside a blow-molding machine.
Energy consumption 20% below the competition
The PET-Line features 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. Overall, 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 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.
