New tight-flask machine offers improved molding quality, productivity. (New product).A new concept for tight-flask green sand molding based on the Seiatsu (air-flow) process has been introduced by Japan's Sintokogio, Ltd., and Roberts Sinto Corp., Lansing, Michigan “Lansing” redirects here. For other uses, see Lansing (disambiguation). Lansing is the capital city of the U.S. state of Michigan, and the state's sixth largest city. . Known as the "ACE" (aerate-compact-ecology) series, the machine was unveiled in May at the Japan Foundry Technology Assn. exhibition in Nagoya City, Japan. Two of the units and complete molding lines were sold at the show, and the machine is being introduced to the North American North American named after North America. North American blastomycosis see North American blastomycosis. North American cattle tick see boophilusannulatus. casting market. The machine features a fluidized aeration-sand filling and mold compaction method combined in a one-piece construction to provide the required compaction and rigidity rigidity /ri·gid·i·ty/ (ri-jid´i-te) inflexibility or stiffness. clasp-knife rigidity for durable, high-speed molding. The sand is fluidized by aeration aeration /aer·a·tion/ (ar-a´shun) 1. the exchange of carbon dioxide for oxygen by the blood in the lungs. 2. the charging of a liquid with air or gas. aer·a·tion n. during filling to produce a "free-flowing" effect. As pressure within the sand chamber increases, molding sand (Founding) a kind of sand containing clay, used in making molds.

The compaction method and arrangement are unique in that the air-operated pads that are above the higher pattern areas are lowered, while those above the flat or lower areas of the pattern are in the "up" position. At the completion of the squeeze, the reaction force of the sand pushes all of the compaction pads back, and the squeeze head becomes flat, resulting in a strong, uniformly compacted mold. The machine's "feedback system" results in the creation of a flat mold surface, eliminating strikeoff and reducing spillage by as much as 66%. The compaction pad is altered or reprogrammed 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. the shape of the pattern as well as aeration and squeeze pressures. The unit's leveling system also improves mold stripping properties. Foundries can expect improvements in: air/hydraulic savings, installation footprint, productivity (up to 20%), minimal or zero pit requirements, reduced noise (75 dBA) and efficient parting agent spraying (as containment eliminates contaminants from the work zone and reduces consumption by one-half).
