Wood Plastic Composites
Wood-plastic composites may be one of the most dynamic sectors of today’s plastic indus try. Although the technology is not new, there is growing inter est in the new design possibili ties this marriage of materials offers. The production of WPC typi cally uses a fine wood waste (cellulose-based fiber fillers such as hardwood, softwood, plywood, peanut hulls, bamboo, straw, etc.) mixed with various plastics (PP, PE, PVC). The pow der is extruded to a dough-like consistency and then extruded to the desired shape.

Compared to many other processes, online compounding and extrusion exhibit short performance timescales, con sistent with the mixing time of the extruder. For high formulation quality, the feeding system must achieve and maintain its required blend ing accuracy within this brief time. Key to a feeder’s ability to at tain high accuracy over short intervals is the resolution of its weighing device and response of its process controller. As the illustration at right shows, lengthy performance times cales permit a given blending accuracy to be attained with a low-performance weighing system. However, to achieve the same accuracy in the short interval characteristic of compound ing and extrusion operations, a much higher weighing perfor mance is required.

With the diversity of organic components used in wood/plastic composite processing, there is no single answer to reliably handling these potentially difficult materials.
Pre-purchase testing helps determine the optimal combination of bin design, agitation, and other flow aid strategies for the specific material in use. Our fully equipped testing facilities are available to evaluate your materials and determine the optimal combination of equipment components to assure the highest level of accuracy and reliability. Computerized performance test reports document equipment performance.
Feeder design and agitation solutions are also key to handling difficult bulk materials. We offer over 30 years of experience in material handling technology.Download Product Specification Sheets

For Wood and Other Organics
Our loss-in-weight feeders offer the perfect solu tion to precise feed rate control of the full range of wood and other organic components in wood/plastic composites. Fea tures include stable, all-digital SFT weighing technology with 1:8,000,000 resolution in 20ms, large hemispherical feed bowls, extensive agitation options, and metering screw selection.
For Resins, Regrind, and Additives
Our K4G Feeding & Blending System is designed for the online blending of up to six components at low to medium rates. Able to accommodate various feed ers for combining pelletized, granular, and powdered or flaked materials which are blended simultaneously on the extruder. The K4G sys tems are available in 1-, 4-, and 6-ingredient stands, specially designed to be mounted di rectly on the extruder in a highly compact configuration. To facilitate cleaning or material changeover, each K4G feeder easily swings out providing full, unobstructed access.
For Powders, Flakes, and Non-Free-Flowing Materials
Our standard and Compact Line single and twin-screw loss-in-weight feeders gravimetrically control the flow of even the most challenging bulk solid materials at rates as low as 100 g/hr.
High-resolution Smart Force Transducer digital weighing technology combined with the industry’s most advanced loss-in-weight control enables the highest possible accuracy even in the most difficult process environments. The standard loss-in-weight feeders feature stable 3-point weighing. Smaller Compact Line loss-in-weight feeders em ploy precision platform-based weighing.Download Product Specification Sheets
