Largest Vertically Parted Mold Machine Built for Denmark. DISA Group (with U.S. headquarters in Oswego, Illinois) received a contract for the delivery of a jumbo-sized DISA 280B vertical green sand molding system. Molds measure 850 x 1200 mm, making it the largest vertically parted green sand molding system ever produced. This new jumbo-sized molding system provides a space-saving, high-capacity and high-quality alternative to conventional horizontal molding lines. NEWS FROM NET
It works on the vertically parted molding principle of blowing green sand into the mold chamber, which is subsequently squeezed into flaskless molds. In the inaugural installation, the DISA 280B is replacing a horizontal green sand molding line of a similar flask/box size. The foundry is making the switch from its existing horizontal molding arrangement to the large-scale vertically parted machine to gain competitiveness through productivity gains and enhanced casting quality. These improvements are fundamental to the foundry’s success in its market sector. NEWS FROM NET

The contract includes the design and changeover of existing horizontal patterns to a vertical orientation. This assures that the foundry will be able to continue to use more than 98% of its existing patterns. The foundry expects to begin production without any compatibility problems as the new line takes the same position of the existing mold line on the foundry floor.. NEWS FROM NET
The MM casting process – Precision investment casting process The aim of this guide is to enable the designer to take advantage of the technical and commercial benefits offered by the MM casting process. Also included in the guide are design ideas and considerations to help and stimulate the design process. NEWS FROM NET
Micro Metalsmiths continues to develop its process so as to meet ever more exacting market challenges. For over thirty years Micro Metalsmiths has refined its techniques for excellence in the production of copper and aluminium alloy investment castings. Micro Metalsmiths has combined its impressive investment casting technology with best practice CNC machining, so allowing many of the constraints placed on engineering design to be overcome. All this is carried out within a BSI accredited ISO 9001 Quality System.
NEWS FROM NET Why use the MM casting process Reduce overall costs by Designing for Manufacture: simplify an assembly by combining a number of parts: eliminate joining processes: reduce the part count whilst improving the integrity of the finished product. Reduce time to market through use of Rapid Prototyping technology and obtain casting, machining, assembly and packaging from one source. Finished metal parts are deliverable from concept in less than four weeks. Design flexibility, with quick modifications to tooling that costs 90% less than for a pressure die casting, whilst maintaining economic batch quantities of up to 500,000 parts per annum.
What the MM casting process can deliver: High quality finish, detail and specification. Thin walls as fine as 0.2 mm, typically 1-3 mm. Light weight components, weighing as little as 1g can be produced using techniques to minimise material usage whilst retaining component integrity. Maximum size of 190 mm x 160 mm x 160 mm. A length of 250 mm is possible providing no other dimension exceeds 100mm. Complex detail on internal and external features. Superfine surfaces with 0.8 micrometres being the “as cast” finish. Zero draft angles NEWS FROM NET
The Sure-Trak shot control system is a real- time, all digital, closed-loop system to increase die-casting quality. Mercury Castings has seen success in reducing air entrapment during the slow shot phase on a variety of parts, including these outboard engine covers NEWS FROM NET
