Using the injection moulding technique, WPC granulate from JELU is used to manufacture the beauty cases shown in the picture. To enlarge the picture, please click on it. Wood plastic composite (WPC) is a new material that is experiencing high growth rates worldwide. The new composite material consists of wood, plastics..
both injection molded and extruded WPC samples made with an unmodified, acetylated, thermally modified or furfurylated wood component in a polypropylene (PP), high density polyethylene (HDPE), cellulose ester (CAP, a cellulose ester containing both acetate and propionate substituents) or polylactate (PLA) matrix
The processes for manufacturing WPCs include extrusion, injection molding, and compression molding. . Most WPC products in the USA are utilized in building materials with few exceptions for residential and commercial building applications, which means that building codes are the most important national rules for the..
shapes and profiles that can be cre- ated with injection molding provide the potential for diversifying from the current WPC markets. The in- jection molding process involves two steps. The first is to melt-blend or compound the wood-plastic mix- ture, and the second is to force the molten WPC into a mold under high pressure
WPC, including wood filler treatment, the role of coupling agents and compounding. It describes the machinery used for producing WPC, and gives a introduction to mold manufacturing. The use of WPC as an alternative to pure thermoplastics in injection molding processes is discussed. Furthermore it is described how..
Apr 22, 2008 . The Extrusoregal is a shelving system made of extruded WPC hollow chamber profiles. (Picture courtesy of mehrwerk designlabor.) Injection moulding can be used, for example, to produce upholstery backings for office chairs (left picture) or for terrace flooring (right). (Picture courtesy of Werzalit.)..

However, recent developments in the manufacture of WPC compounds have significantly improved the quality, consistency, and capability of this environmentally friendly material. In fact, the latest generation of WPCs can be run smoothly through traditional injection molding equipment with minimal adjustments to process..
Sep 3, 2017 . ABSTRACT. The fibers orientation in the polymer matrix is an important factor determining me- chanical properties of products made of composites by means of an injection molding process. The fibers arrangement has an effect on shrinkage of the composite and the dimensional accuracy of molded piece
Green Dot, a bioscience social enterprise serving plastics manufacturers and style conscious consumers, is introducing new Terratek WC wood-plastic composite pellets, ideal for injection molding and sheet extrusion. The smaller more uniform pellet size is optimized to ensure superior processing compared to other..
Besides the polymer, the processing method and formulation variables also have a significant effect on the structure and surface properties of WPC. Stark et al.  and Migneault et al.  stated that injection-molded surfaces have a polymer-rich layer and are smoother compared to extruded material which showed voids and..

Usually, WPC's melt viscosity is remarkably large, if you raise the molding temperature at 200 higher in order to reduce the melt viscosity, wood components will thermally decompose, resulting in bad odors and burns resulting in blackening. There are many difficulties to realize commercial production by injection molding
The material has exceptional mechanical properties, high dimensional stability, and supports the manufacture of complex profiles. WPC based on polyolefins (HDPE, PP) are typically processed by means of direct extrusion and injection molding, while PVC-based WPC are processed using direct extrusion, co-extrusion or..
