Direct extrusion is the production of wood Composite materials (WPC) profiles of the main methods. However, for thin-walled hollow profile, its molding process requires pre-drying of raw materials, pre-mixed with granulation, and use the vacuum forming mold. Until now, all the hollow WPC Doors and windows Profiles are still using pellets for extrusion. From Minnesota's Aspen automatic extrusion processing and design company changed this situation. The company is specialized in the development and design WPC extrusion die and associated downstream equipment company. 50% of companies use PVC wood powder and blend doors and windows profiles, the profile includes two hollow parts, PVC is divided into two layers, a layer of white layer of dark gray. The profile width of 3.5in., Wall thickness of 0.080in.. Directly out of a cost advantage. Eliminating the need for pre-drying process, material can be saved per pound 6 to 7 euros, rather than through the granulation process can save 12 per pound of material 15 dollars. The core of the extrusion system is a parallel reverse rotating extruder (Krauss-Maffei's KMD90-36), and ordinary compared to conical twin screw extruder, parallel twin-screw extruder that the price to low 15% ~ 20%. Customized material handling Thin profile of the direct extrusion face a major problem is how to respond to changes in density of WPC raw material, because the uneven impact of feed will die. Aspen Automation out of professional products, Mr. President DonaldZoubek that even minor changes in material density will cause a problem of molding thin-walled sections. Here, the financial body of the pump does not apply, because the financial body of the pump increases the shear stress in the material is too high, overheating of the WPC will be the destruction of its fibers. Aspen Automation professional products company out of the upstream use of professional mixing and preheating equipment extruder to provide uniform materials. The system can be wood flour, PVC powder and 20% recycled material supply to the WPC extruder. The production line filling machine with HapmanConveyors company, Inoex's gravity measurement type hopper. The material supply hopper to a mixing device in a small mixing, the mixing device using a pair of small aspect ratio of synchronous twin-screw preheating the material mixed. Synchronous twin-screw will set the electric heating material preheated to 80 . Been preheated material by gravity into the extruder, Krauss-Maffei's long barrel extruder (36:1 aspect ratio) by high-pressure exhaust port and exhaust the material in vacuum discharge of gases and volatile. Lead aircraft makes screw tube can become wider, which is conducive to increasing production. From Aspen Automation professional products company out of the latest improved die. The downstream production line equipment, including 4 sets of dry-type setting mode, a cooling device and a series of vacuum forming mold with the template slot. Experiment, the production line profiles of the speed of 10.5ft/min, about 400lb / h. The line of vacuum forming die and mold will then Sell To the Andersen Corporation. Anderson company currently no direct profile extrusion production line. Anderson's technology is still ahead Other doors Window profile production companies. However, out of Aspen Automation professional products directly out of the company has issued production licenses to the Trex Company and LP Building Products company for the production of hollow thin-walled fence. Aspen said they are optimistic about the potential of Anderson's, Anderson will be awarded licenses to companies for the production of window profiles.
