Extrusion systems provide accurate weight control and quality parts.Extrusion systems from ZW Hydraulik AG and marketed by this company in the United States United States, officially United States of America, republic (2005 est. pop. 295,734,000), 3,539,227 sq mi (9,166,598 sq km), North America. The United States is the world's third largest country in population and the fourth largest country in area. are featured in a four-page, four-color brochure. Sophisticated rubber compounds are said to require a higher level of process technology to satisfy end user demands. The quality of these high value rubber molded mold 1 n. 1.

Reducing reject losses is said to give customers a competitive edge. The basic design goals of the company's extrusion and preforming systems are to give customers accurate weight control, better shape and quality parts to improve their process output. The gear-pump extruder, highlighted in the literature, is a continuous process. It can be hot fed with strips from a mill, or cold fed with strip from stock. This capability is said to make the gear-pump extruder/preformer a unique and versatile system. It is also said to be ideal for continuous screening of compounds, as well as pelletizing Pelletizing or pelletising is the process of compressed or molding of product into the shape of a pellet. A large range of different products are pelletized including chemicals, iron ore, animal compound feed, and more. . The screw-type extruder is said to provide a smooth transfer of the compound to the gear-pump. The gear-pump presses the compound through the die at a regulated and precise speed. A ram type extruder is also featured in the brochure. The revolving double barrel Double Barrel is a popular reggae single by Dave and Ansell Collins. Written and produced by Winston Riley it was recorded in 1971 and became one of the early breakthrough ska hits internationally. system separates the feeding from the preforming system. One barrel can be loaded, while the other is extruding. This is said to ensure high productivity with consistent preform accuracy. The cold fed ram type extruder is said to give a very high level of process repeatability. Polymer Machinery www.polymermachineryco.com [ILLUSTRATION OMITTED] |
