PX series(250 – 3.200 kN)
All-electric injection molding machine: Power meets flexibility
The PX series is the answer to your requests for more flexibility while increasing productivity. You can assemble your PX precisely to your production requirements from a wide selection of components based on a modular design.
- All-electric clamping unit
- Individualized combination of injection and clamping units
- Many additional equipment and retrofitting options available based on individual production requirements
- Mold fixing platens with generous dimensions for flexible use of molds of various sizes
Greater selection of ejector versions
Robust or intricate: Either a servo hydraulically driven ejector or an electrically driven ejector is advantageous depending on the requirements during parts removal. The PX offers both options.
Robust and flexible: The hydraulic ejector
In your production, are you using molds with hard striking ejector plates? If so, the extremely robust hydraulic standard ejector of the PX is perfect for your needs. It can withstand all mechanical pulses or impacts from the mold. The large ejector stroke also provides a great deal of flexibility for any mold. If more ejector force is required, an increase of 50 percent can be selected for any PX. In order to optimize the removal of free-falling parts, the ejector speed can even be increased by 100 percent. Furthermore, every ejector is also optionally available as an ejector plate.
Extremely precise: The electric ejector
Do you want precise transfer of parts to a robot removal? If so, the optionally available electric ejector for the PX is recommended. It works with absolute precision and reproducibility. As is the case with the hydraulic ejector, the electric ejector also features versions with increased force or speed. Every electric ejector features a motor brake to hold the position for spring force molds. For particularly clean ambient conditions, it can also be encapsulated.
Force and speed
A “boost” for the injection unit
Material, part geometry, desired output. These values define how high the performance of the injection unit of a machine has to be. The PX meets your needs through flexibility.
More injection speed
For components with thin wall thicknesses or long flow paths, every PX has the option to be equipped with increased injection speed.
More nozzle contact force
Thanks to the two servo hydraulic injection unit barrels, the PX standard alone features sufficiently high nozzle contact forces. If very high nozzle contact forces are needed for special nozzle geometries, e.g. for dipping nozzles with large cross-sections, then this can easily be configured for the PX using the assembly kit with additional options.
More plasticizing capacity
Do you want to increase the output for your applications by increasing material throughput? No problem. With the PX, each injection unit is also optionally available with increased screw drive capacity.
More injection unit speed
Due to the high-performance integrated servo hydraulics, the travel speed of the injection units of the standard version alone is at least 50 mm/s. An option even exists to double the injection unit speed of any PX to 100 mm/s. Therefore, in applications using lift-off nozzles, cycle time can be significantly shortened and the start-up accelerated.
Fascinating insights into the all-electric PX series
A marvel of flexible design
Leading combination for clamping and injection units
Versatile clamping unit for outstanding productivity
The efficient and highly dynamic 5-point double toggle lever coupled with intelligent servo drive technology ensures outstanding productivity and cost-efficiency while also providing optimal mold protection.
Great variety of clamping unit/injection unit combinations
Perfect utilization of production space: Thanks to the split machine bed, the clamping unit and the injection unit can be combined in a variety of ways – making the machine only as long as it really needs to be. For example, if a large clamping unit is combined with a small injection unit.
The entire bandwidth of screws and non-return valves
All standard PX plasticizing units stand out thanks to an excellent melt quality and cover a wide range of applications. Furthermore, if you have special processing requirements, you can choose from a wide range of screws and non-return valves – even for high-temperature and high-performance versions (HPS) and, of course, with suitable wear protection.
Enlarged mold fixing platen
80 tonnes of clamping force would be enough, but your mold needs more space? If so, you should opt for the PX 81. This will give you considerably more mold installation space for even more adaptability in everyday manufacturing. You achieve this adaptability without having to purchase the machine with the next level of clamping force. Of course, the maximum permitted mold weight is increased as well.
Maximum platen parallelism for any mold weight
More space means more weight. With the PX, you can be sure that if the mold fits into the machine, then the clamping unit has also been designed for the greater mold weight. The wide support of the moving platens on linear guides and the stiff machine bed under the clamping unit guarantee perfect platen parallelism.
Advantages for packaging applications
Short cycle times with maximum part output is the main requirement of the packaging industry. In practice, this means that molds are used with the highest possible number of cavities. This is precisely where the PX shows its strengths. Particularly where high flexibility is required due to small batch sizes and high functional integration. The PX offers the perfect package: It is robust, fast, cost-efficient and flexible.
Strengths of the PX in PACK applications
– Enlarged mold fixing platens for molds with many cavities
– Dynamic clamping unit for short dry cycle time
– High injection speed for thin wall thicknesses
– High plasticizing capacity for high material throughputs
– High ejector speeds
– Parallel movements for short cycle times
– Low energy and water consumption
– Maximum free space for parts logistics under the clamping unit
– High-performance screw (HPS screw) for optimum melt quality with short cycle times
– Special automation solutions for the packaging industry
Advantages for medical applications
Applications for medical technology require very high product cleanliness and quality. Even the standard version of the PX is suitable for clean production conditions. Furthermore, the machine can be adapted for use in specific medical industries through additional equipment and retrofitting options. In this version, belt drives are enclosed, lubrication systems are closed and operation is possible using food-grade NSF H1 oil.
Strengths of the PX in MED applications
– Cleanroom-compliant surfaces inhigh-gloss and antistatic design
– Grease-free, chrome-plated tiebars
– Automatic central lubrication
– Closed lubrication of the toggle
– Complete encapsulation of all drives
– Removable housing elements forperfect accessibility
– Electric ejector
– Very quiet during operation
– Food-grade NFS-H1 oils
– Machine height setup to facilitate cleaning underneath the machine
– Qualification support
