Original Press Release:
Perfect for Siding, Fence, Pipe and Profiles, TP Series Parallel Twin Screw Extruders Set New Standard for Output Rates with Wide Processing Window
Four models, 93-172mm dia., with high-torque gearbox and up to 224 kW motor - outputs as high as 1800 kg/hr for rigid PVC profile and 2275 kg/hr for rigid PVC pipe or sheet
April 2003-CPM Milacron brings unparalleled productivity to parallel twin screw extrusion, announcing its line of high-output TP extruders, available in sizes 93, 115, 140 and 172 in conjunction with NPE. Representing the CPM Milacron machinery family, the TP line delivers best-in-class outputs, while providing an exceptionally large processing window. The TP's drive design, channel depth, optimized centerline-to-diameter, and an L/D choice of 26 or 33:1 for all sizes make these machines ideal for a wide range of applications from rigid profile and woodflour plastic composites to flexible PVC pelletizing.
Maximum output for the largest model ranges from 1800 kg/hr for rigid PVC profile to 2275 kg/hr for rigid PVC pipe and siding. The versatile TP machine provides wide latitude for profile extrusion, along with significant cost- and space-savings. Between them, the four TP models bring exceptional consistency and throughput range to a full spectrum of applications - PVC pipe, window profiles, siding, sheets, and wood flour/plastic composites, as well as rigid and flexible PVC pelletizing.
Best-in-class capabilities
The TP line is designed for best-in-class torque and efficiency in working the raw material to provide unmatched processing consistency and throughput range. State-of-art screw design provides superior surface area for gentle plastification of the material. This optimizes heat transmission efficiency over the full length of the screws to the feedstock, while optimizing the compression ratio for longer screw and barrel life. The CPM Milacron Integrated Crammer Feeder with torque based speed control is provided to ensure complete flooding of the screws for proper filling of the screw channels. Use of the crammer feeder aids in achieving efficient heating of the raw material for maximum output rates. Additional features of the feeder include a slide-gate shut-off and purge chute. Alternative feeding systems include a gravimetric feeder, a metered dosing feeder, and a co-rotating twin-screw preheating feeder system known as the Material Enhancement Delivery System. (MEDS).
An Eisenbeiss Torque Master gear box - standard on all TP machines - provides superior torque and thrust capability compared to previous parallel twin gear box technology. The gearbox contains both reduction and distribution gearing in an integral housing. Exceptionally quiet, the gearing system delivers long bearing life and up to 96,130 Nm of maximum available torque in the largest extruder size.
Optimized heating and cooling
Precision control of process heating and cooling assures highly consistent and efficient extrusion performance. TP extruders produce a homogeneous melt temperature with pulse-free, positive-displacement pumping making them ideal for quality extrusion of vinyl and similar heat- and shear-sensitive materials with a wide processing window and high output rates. Increased energy efficiency is achieved by proper filling of the screws and applying an optimum balance of mechanical work and external heat energy to the material.
For degassing, single or dual vent zones are provided, depending on L/D, and a liquid-ring vacuum pump produces optimal air evacuation while reducing overall maintenance.
A high-efficiency electric heating/water cooling system provides temperature control to the barrel zones. This design provides superior cooling properties and is nearly maintenance-free compared to oil-cooled systems. Screw temperature control via sealed, closed-loop water is standard; an active oil system with an individual temperature control zone and heat capacity of 9-18 kW (depending on model) is available as an option for the screws. Eight die zones (including entry adapter) are standard, and up to 18 are available.
Unitized base advantages
Unitized construction mounts all components on a single base for fast, easy installation and compactness. A narrow footprint enables more production per square meter of floor space. The largest machine size has a footprint of 8247 x 1758 x 2873mm (LxWxH), without entry adapter and with feeder and hopper.
Windows NT in a PC-Based Control
TP machines come standard with either a discrete control or Milacron's patented PC-based XTREEM NT control. The XTREEM control combines advanced microprocessor capabilities with high flexibility and connectivity. Proven Milacron software provides full production control, including slaved co-extruder speed control, SPC monitoring and analysis, process alarms, and process "recipe" storage and call-up. Operators are provided with on-screen control panels, instant-access information screens with full-color graphics, and multi-language capability.
The PC-based XTREEM NT control brings Ethernet networking to the factory floor and provides the full functionality of a Windows® NT personal computer, including the Microsoft Internet Explorer® suite of software and a host of other PC capabilities.
