The new TF 1200, TF 2000, and TF 4000 models, which, like their predecessors, are used in the jewellery industry and in precious metal foundries, are completely new developments. They are equipped with new high performance induction generators that reach the melting point significantly faster and ensure thorough mixing and homogenisation of the molten metals. Depending on the model, the capacity ranges from a crucible volume of 1200 to 4000 ccm, corresponding to approx. 60 kg of 18 ct. gold.
The TF machines are equipped with 32-bit induction generators providing 15kw - 60kw output power (depending on version). Low-frequency tuning means excellent through-mixing on the molten material. All versions are now controlled via a console with an LCD display with full text readout.
The operational safety of the machines has been optimised in many respects. They are now controlled via an LCD display, with the option of storing 20 temperature presets.
The melting unit and crucible can be tilted and locked in position by the user at multiple angles for gentler filling. Such “soft pouring” also prevents damage to the crucible. Pouring off is continuous and gradual, using a pivot lever. The operator is forced to stand to the side of the machine – away from the dangers of the pouring off area.
In the rare event of a crucible breaking, the machine is not damaged – all of the assemblies are covered by a separate protective housing, and every model has a large collecting tray under the melting unit to prevent potential loss of metal.
We have paid the greatest attention to the energy efficiency and operational safety of the machines. Normally with open melting machines, the induction field that generates the energy for melting the metal is scattered over a relatively wide area. This uses up energy and can be burdensome for the machine operator (electro-smog). As with the large melting machines introduced recently, we have managed to almost completely prevent this scattering of the induction field. The induction energy can then be directed where it is needed – into the crucible or into the molten metals. This technology has enabled tenders to be won against providers with machines that needed double the energy consumption for the same output. The potential for savings is therefore significant, which is a critical criterium for many foundries.
Until recently a high kW figure was the indicator of the performance of a casting machine. Today the majority of customers correctly associate high output with high energy consumption and high costs. The critical thing is to get the maximum benefit from the least possible energy consumption. The new TF machines offer the same maximum outputs as their predecessors – but the effective power consumption for a comparable melting load is significantly lower.
