Tecnology
From the technologic point of view, Electromac’s machines are at the cutting edge on the market because they are the result of a continuous research aimed at optimizing the product, by resolving in the best possible way all the faults of this type of machines, faced during a lot of years of work in foundries
In particular, the design of the automatic sand core forming machine using the hot box system (model Elmac F1 and Elmac F2) has been carried out with the main goal to guarantee during the whole production cycle the manufacture of sand cores without burrs and perfectly pressed even using low pressure in sand injection. This result is achieved by adopting a hydraulic die closing system on four hardened and ground guides. Here the die block is driven by a hydraulic master cylinder which develops a closing force of 3,000 kg. The die heating plates are made of a steel which is extremely resistant to heat deformation. This way, perfect and hermetic die closing is constantly obtained at all temperatures.
The metering unit for liquid resin D70-L has been designed to guarantee with a completely automatic cycle a perfect metering of the necessary components for the production of sand cores. The very good mixture of siliceous sand, liquid resins and catalysts is guaranteed by volumetric metering devices, a system that has proved the best among all metering systems on the market.
Furthermore, Electromac’s technological development has allowed to make the sprue cutter TR400 / 2S, an absolutely reliable, precise and easy to use cutter. The result is a machine that can be considered the best on the market, especially because of the electropneumatic closing side vises, that block quickly and strongly the piece.
Elevated speed in cutting pieces, reduced consumption of abrasive discs, easy management of the functions of the machine, maximum speed during the phase of preparation of vises complete the advantages of a machine that completes in the best possible way Electromac’s family of products for nonferrous metal working and casting.
Assembling
Electromac’s machines are designed to be the best: this means also that when they are being manufactured always the best materials and components are chosen. This means that each machine is accurately assembled by expert hands, that every manufacturing and assembling phase undergoes a strict control, that all materials have to come up to very high qualitative standards.
In the assembling protocol of Elmac F1 and Elmac F2 controls on closing parallelisms are scheduled and a system of plugs and screws guarantees the precision of alignment even if they have to be disassembled for maintenance. A steel which is extremely resistant to heat deformation is used for die heating plates and the machines are hard-wired and supplied with control board and commands on board, so that they can work immediately after connecting them to electricity.
In the metering unit for liquid resin D70-L all the components getting in touch with sand, resin and catalysts are made of highly corrosion proof materials, while the automatic sprue cutter machine TR400/2S, together with the models TR350/2S and TR300/2S, just for the quality of its components, guarantee to last for a long time even under extreme working conditions.
