2. Zinc casting is suitable for countless applications, from simple window fittings to complex electronic components and automotive components to spectacle cases. To which industry do your biggest customers belong? The die cast parts are mainly supplied to the electrical industry and drive technology. Brackets and fittings for doors or windows are also produced for the fastening industry. 60 - 70 % of these die cast parts are exported and approx. 30 % are produced for Swiss customers.
3. How has your industry and applications developed in recent years?
Many die casting foundries are following the trend and investing in Megacasting, the joining of several components into one die cast part. It has the potential to revolutionize the manufacturing process of automobiles. Since Macrocast specializes in small-series parts and produces small parts, Megacasting is not done. There are no such changes coming in the casting process for small parts. The more cavities a mould has, the greater the challenge to ensure that all castings in the same production cycle are cast in perfect and equal quality.
However, there is a clear trend towards connectivity. Connecting the temperature control unit to the machine control system simplifies the production process significantly and is indispensable in terms of quality assurance. The temperature controller ensures that the die cast parts are produced without quality problems.
4. In what way do Tool-Temp units simplify the production process in your die casting foundry?
The greatest risk in the production of die cast parts is material doubling, which can occur due to cold fronts during casting (too low casting speed leads to premature solidification). Especially with thin-walled castings, material doubling is particularly visible and cannot be accepted. The solidification temperature of zinc is 387 °C and therefore, Macrocast relies on Tool-Temp oil tempering units, by controlling at high temperatures.
Our goal is the continuous optimization of cycle times, and this is achieved by using the Tool-Temp oil temperature control units TT-248 (up to max. 200 °C), TT-288 / MP988 (up to max. 250 °C).
5. How many hours are the Tool-Temp units in use every day?
We use the units for 13 hours per day (at the end of the shift the units are switched off), but they can easily be used in 24/7 operation.
6. We are very grateful for our long-standing good business relationship. What brought you to Tool-Temp years ago?
More than 6 years ago, employees came across Tool-Temp through internet research. Since the focus was on independence, individual solutions, quick communication channels and fast availability of equipment and spare parts, it quickly became clear that Tool-Temp would become the business partner.
7. What are your experiences with the Tool-Temp units?
The temperature control units are very reliable, this is proven by their control accuracy. They easily withstand the rough everyday conditions in die casting.
