More Machines Outfitted for Microcellular Foam.MuCell microcellular foam technology developed by Trexel Inc. of Woburn, Mass., has been licensed by Arburg Inc., Newington, Conn. The license applies to 15-250 ton Arburg machines in North America North America, third largest continent (1990 est. pop. 365,000,000), c.9,400,000 sq mi (24,346,000 sq km), the northern of the two continents of the Western Hemisphere. . Arburg is the third press maker (after Engel Canada and Uniloy Milacron) to take a MuCell license. The MuCell process heats and pressurizes carbon dioxide carbon dioxide, chemical compound, CO2, a colorless, odorless, tasteless gas that is about one and one-half times as dense as air under ordinary conditions of temperature and pressure. or nitrogen to a supercritical Adj. 1. supercritical - (especially of fissionable material) able to sustain a chain reaction in such a manner that the rate of reaction increases critical - at or of a point at which a property or phenomenon suffers an abrupt change especially having enough mass state in which the gas behaves like a liquid. It is injected into the melt to produce uniform closed cells as small as 5-50 microns. MuCell molds lightweight, thin-walled products that could not be made with conventional foaming, says Trexel. These products are reportedly free of stress, warpage, or sink marks. The process reportedly reduces melt viscosity, allowing use of up to 50% lower injection pressure and 30-40% less clamp tonnage TONNAGE, mar. law. The capacity of a ship or vessel. 2. The act of congress of March 2, 1799, s. 64, 1 Story's L. U. S. 630, directs that to ascertain the tonnage of any ship or vessel, the surveyor, &c. . MuCell auxiliaries can be supplied with a new Arburg machine or retrofitted. They can be turned off when foaming is not required. Arburg has already delivered one 66-ton, MuCell-capable press in North America. A major reason for the purchase was the potential to cut cycle times by 20-30%, according to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. Arburg. Shorter cycles are said to result from faster molding filling, lower melt temperatures, and reduction or elimination of hold time. |
