Cincinnati Milacron Extrusion Systems features “Plug & Play” WPC Extrusion System


Big System Performance, with affordable prices designed for Wood and Natural Fiber Plastic Composite extrusion.

Cincinnati Milacron’s “Plug & Play” Extrusion System offers wood and fiber composite extrusion processors a complete turnkey approach enabling quick market entry and rapid on-line production with Cincinnati Milacron’s proven extrusion technology. The Plug and Play system has all a processor needs to quickly get into the WPC business and generate revenue. The ideal solution for a quick start up is using non-complicated but proven technology, affordable and very effective. It’s a very practical American approach that works! This system has all the performance and options of a big heavily engineered system including the traditional material handling equipment, transfer equipment, mixing, drying, delivery system, die set and all the downstream cooling and cutting equipment. The “Plug & Play” system avoids costly “add-ons” and complicated custom controls that are loaded into many Euro extrusion systems. All that is missing is the material formulation, the material and the finished parts”.

TC86The key element of the “Plug & Play” system is the industry leading Cincinnati Milacron Extrusion Systems workhorse TC86, using advanced large conical twin- screw technology to bring unique compression and low shear-mixing capability to an unmatched material processing range. The TC86 is an excellent machine for use with wood fiber /plastic composites with up to 70% fiber loading along with high output, offering homogenous melts from various blends of natural and synthetic fibers, heat/shear-sensitive thermoplastics, recycled plastics, coupling and nucleating agents, pigments and other materials.

Industry Leader in Wood & Natural Fiber Plastic Composite Systems

Milacron Extrusion Systems has the WPC industry leading advantage due to superior screw design that provides processors with maximum output capability. Milacron has the most extensive industry expertise in WPC with over 280 machines installed worldwide. Recognized as the global leader in Wood Plastics Composite (WPC) shapes for decking, rails and other products, Cincinnati Milacron Extrusion Systems bring superior versatility, melt homogeneity and process control to the ever-emerging applications for WPC profiles and structural components.

Plug & Play System Advantages

  • The Plug & Play system features a significant reduction of capital outlay as compared to larger complex engineered systems while providing a powerful production capability of 635kg per hour of output. As a comparison, the Plug & Play system with excellent production capabilities is available for under $1.0 M, while larger systems can have significant delivery issues and run from $2.0 M to $2.5 M (USD) in price.
  • The Plug & Play offers processors lower maintenance costs due to the simplified system design and extreme manufacturing flexibility than larger, more complex systems. The “Plug & Play” enables quick resolution and quick restart.
  • The Plug & Play can be set up with a single or multiple extrusion lines and has the capability to be scaled larger at a later date once sales increase for the processor.
  • The Plug & Play TC86 extruder is a very effective positive pump for head pressures required for the full range of WPC products. The TC86 features a small exit diameter which reduces rotational shear and screw thrust while increasing pumping efficiency into the die.  The conical twin screw action generates positive pumping pressure for quality extrusion of viscous rigid PVC and WPC material which is also critical for higher head pressures that are required for engineered profiles with thinner walls and small die openings.
  • The TC86 large diameter screws (176 mm tapering to 86 mm with a 27:1 LD ratio) optimizes the feed zone surface area for fast, uniform heat transmission from the screw to the material.  The tapered screw design allows a larger feed zone for “fluffy” light bulk density materials and applies a natural compression during processing which results in wood flour being “wetted out” and plastic polymers being properly mixed prior to devolatilization.  The deep flights of the advanced screw technology optimize mixing while reducing shear forces.  High torque at low speeds enables gentle low shear melting and mixing and offers ultra efficient plasticizing in vinyl extrusion.
  • Cincinnati Milacron Extrusion Systems is the only company capable of providing a totally tungsten clad conical barrel for high abrasive WPC formulations.  All of the technology is fully supported with customer laboratory testing in the USA, China and Europe.
  • The Plug & Play system includes a high intensity water spray-cooling tank for increased output over traditional sizing/water bath technology.
  • The Plug & Play TC86 extruder comes standard with the Cincinnati Milacron MOSAIC touch screen control system. Featuring extreme reliability and precision and a 15” (381 mm) LCD screen, the MOSAIC has self-diagnostics and Ethernet TCP/IP connectivity. Proprietary Cincinnati Milacron Extrusion Systems software provides full production control including SPC monitoring and analysis, process alarms, slaved co-extruder speed control and process “recipe” storage with call-up capability. Operators use on-screen control panels with instant-access information screens including full color graphics and multi-language capability.
