Disamatic
Disamatic is a molding machine that has been manufactured by the Danish manufacturer Dansk Industri Syndikat (DISA) since 1964 . The Disamatic molding machine produces vertical mold blocks that are transferred to a molding line and does not require any molding boxes . This process enables the production of large quantities and is therefore mainly used in the series production of components, for example for the automotive industry. According to the manufacturer, 1,450 foundries have been equipped with Disamatic systems to date .
history
In 1961, DISA acquired a patent for a molding machine that could eject vertical shapes. In contrast to the previously known automatic molding machines, which produced horizontal molds, the cost of producing a model is higher, but the number of cast parts that can be produced in a certain time also increases. In 1962 a model of the Disamatic was presented at the GIFA foundry trade fair , and in 1964 it was first delivered to a Danish foundry. The possible ejection speeds of the mold blocks and the maximum sizes have been continuously increased since then: Whereas in 1994 the ejection speed was 370 molds per hour and the maximum size of the mold block was 950 × 700 mm, today Disamatic systems with ejection speeds of 510 molds per hour and mold cross-sections of 1200 × 1050 mm are available.
technology
The Disamatic molding machine has a molding chamber with two swiveling model plates on the sides. At the beginning of the molding process, the molding material is fed into the molding chamber from a container, which is usually arranged above the disamatic . This can be done by gravity or by external application of pressure. In the next step, the molding material in the molding chamber is compressed with a plunger so that molds are created that can retain their shape even without a molding box. Now the form is ejected; If necessary, cores can still be inserted or introduced with a core shooting device. In the last step of the plunger pushes the mold block on a belt conveyor where the casting process depending on the installation directly from the crucible furnace or a ladle takes place.
