Mag-tec takes advantage of semi-hot chamber diecasting technology.Mag-tec Casting Corp., Jackson, Mich., has always been a company willing to take risks for the sake of innovations. The company feels one of the strongest keys to remaining competitive is to adopt new technology and try new things. Following that business philosophy, Mag-tec had no hesitations in installing the new DXHV350 semi-hot chamber diecasting machine from Toshiba Machine Co. Ltd., Chuo-ku, Tokyo, Japan. The machine, distributed in the U.S. by Toshiba Machine Co., America, Elk Grove Village Elk Grove Village, village (1990 pop. 33,429), Cook and Du Page counties, NE Ill., a suburb of Chicago; inc. 1956. With a population of c.100 at the time of its establishment on open farmland, the village has grown dramatically and steadily, largely because of its , Ill., is the first of its kind in production 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. . It has been running at Mag-tec since March. Typically, diecasting machines work in one of two processes--hot chamber or cold chamber. The DXHV350, however, is a semi hot chamber machine that transfers molten aluminum to the die using an electromagnetic pump-aided system. Together with a unique patent-pending suspended vertical squeeze-casting injection system, the machine enables 100% filling of the sleeve with minimal temperature loss, thereby increasing the strength and elongation elongation, in astronomy, the angular distance between two points in the sky as measured from a third point. The elongation of a planet is usually measured as the angular distance from the sun to the planet as measured from the earth. properties of the final product.

The DXHV350 also includes Toscast, a state-of-the-art control system that sets, monitors and manages the casting process. Toscast provides the operator with an easy-to-use control system that can automatically compensate for a variety of injection conditions. The setting for start-up requires only two screens, die setting and casting conditions. Once inputted, the conditions can be saved in the internal memory for up to 64 dies. The shot profiles or machine motions also can be displayed. The machine also is fitted with a unique dry powder Dry Powder A slang term for cash reserves kept on hand to cover future obligations. Notes: For example, if a venture capitalist expects bad times in the IPO markets you might hear him say something like, "we want to keep enough dry powder around to keep funding our lubrication lubrication, introduction of a substance between the contact surfaces of moving parts to reduce friction and to dissipate heat. A lubricant may be oil, grease, graphite, or any substance—gas, liquid, semisolid, or solid—that permits free action of system. The system works by first pulling a vacuum on the mold. The die is then electrically charged, and a proprietary graphite graphite (grăf`īt), an allotropic form of carbon, known also as plumbago and black lead.

Typical language: "I leave the rest, residue and remainder [or just residue] of my estate to my grandchildren. , no spray mist in the air and a safer/cleaner work environment. The dry powder lubrication system provides better molten metal flow and helps produce better looking (i.e. surface finish) components that are stronger than traditional diecast components. Since this process is capable of providing effectively "zero-porosity" castings, parts can be welded or heat-treated and can provide optimum sealing capability under high-pressure conditions. Through trials at Mag-tec, the system proved it can produce components that have superior strength, elongation and pressure-tightness properties. "When we tell people they could see tensile strength tensile strength Ratio of the maximum load a material can support without fracture when being stretched to the original area of a cross section of the material. When stresses less than the tensile strength are removed, a material completely or partially returns to its above 30 (kgf/mm2) and elongation of 15% and higher, it gets their attention," said Allen Schroeder, Mag-tec president. By comparison, a typical component from a cold chamber diecasting machine might have elongation of 5% or less and tensile strength between 25-30 kgf/mm2. It is too early for Mag-tec to predict the actual cost savings achieved with the machine, but Schroeder believes in the cost competitive nature of the components it produces. "We should actually be more cost-effective on a final product than permanent or sand molded parts," he said. Select No. 002 at www.moderncasting.com/info [ILLUSTRATION OMITTED] |
