In the past years, the market of investment precious metals has become more and more demanding: nowadays an ingot must have the same aesthetic properties of a jewel.
Using the machines available on the market prior to the launch of HS-VF260, one could manufacture products of reasonable quality, but it was difficult for operators to manage them. As a matter of fact, calibration of work parameters and ordinary maintenance were almost exclusively limited to highly-specialized staff.
The launch of HS-VF260 revolutionized the field: companies all over the world were supplied with tailored tunnel furnaces, scalable according to production types (ingot from 1 ounce, up to 400 ounces or 1000 ounces), whose maintenance was accessible.
The only solution was designing an induction tunnel furnace with an easy and user-friendly interface (HMI touch screen), that could be even completely disassembled with just one wrench.
The furnace is in the open air and the flame is always burning, hence risks of accidents at work are very high.
Higher risks of metal loss.
Significant emission of fumes, whose recovery is very expensive for the company, and development of a strong electromagnetic field.
A lot of consumables, such as crucibles, are used and worn out quickly, implying high operating costs.
The quality of the finished ingot (shininess, purity, flatness) is medium-high.
The furnace requires the constant presence of operators.
