TM Xpress series - High-speed series TM Xpress 160t-450t
The TM Xpress series - your fast track to business success
The new, powerful high-speed model in the 160-450 ton clamping force range. A high-speed variant has been added to the power packs of the proven TM series from WITTMANN BATTENFELD. The new, innovative TM Xpress series stands for excellent injection performance and accuracy.
The user-friendly UNILOG B6 control system offers a wide range of functions, providing support in process monitoring and documentation.
Injection unit - A concept to improve parts quality
- Optimal homogeneity thanks to a uniform screw L/D ratio of 22 :1 or 26:1 in combination with barrier compounding screws for processing HDPE, PP, and PS.
- Min. 2000 bar injection pressure for all screw diameters.
- High injection rate combined with acceleration rates of 10,000 mm/sec2.
- Precise axial movements of the injection unit thanks to linear guides.
- Torque-free parallel nozzle contact due to positioning of traveling cylinders opposite each other.
Clamping unit - Outstanding Features of the TM Xpress
- Short footprint
- Extremely rigid, sturdy clamping plates and machine frame.
- Precise platen parallelism across the entire stroke.
- Low-maintenance linear guides to support the moving platen.
- Self-locking 5-point toggle system.
- Reinforced toggle bearings with low-maintenance toggle sleeves.
- Adhesive central oil lubrication of toggle system.
- High opening and closing speeds thanks to differential gears.
- Short dry cycle times.
- Flexible parts removal in three directions.
- High repeatability of all parameter settings.
- Sensitive mold safety device.
- Mold protection thanks to precise platen parallelism, minimal
- platen deflection and linear guides.
- Low-maintenance and service-friendly design of all machine parts
Ultimate precision and repeatability
Compact design with integrated hydraulic block and easy access to all components. Maximum repeatability thanks to servo-valve control.
High-performance plasticizing systems
- High plasticizing performance with barrier screw.
- Melting performance and homogeneity optimized by additional compounding section.
- Long service life thanks to optimal choice of materials.
Servo motor for metering
- The screw drive is powered by a servo motor positioned in the longitudinal axis of the machine.
- With circumferential speeds reaching more than 1 m/s, an extremely high plasticizing performance with simultaneous low energy consumption is achieved.
- Extremely short cycle times are possible thanks to parallel plasticizing function.
High-performance hydraulic system
Extra high injection speeds- The injection units are equipped with hydraulic accumulators to reach the high injection speeds and acceleration rates required for thin-walled parts.
- Pressure loss is minimized thanks to the short distance between the hydraulic accumulatorsn and the hydraulic block.
- The fast-reacting servo valves installed on the integrated hydraulic block ensure excellent precision and repeatability.
- Loading of the accumulators via a separate loading pump with a reinforced drive.
- Separate operation of the clamping unit with a hydraulic pump of its own, independentof the accumulators.
- Capacity for parallel operation of all functions (opening, closing, ejection, core pulls, plasticizing) is available in this series as standard.
