Aluminium die-casting

Yes, it does. With the Dry Lub System, the mould’s thermal management must be based on the correct cooling processes inside the dies. You need to consider that lubricating with powders requires temperatures 80 °C higher than the standard temperature.

The simulation systems available on the market (Magma type) can solve the problems, although human experience and skills should never be neglected.

There are two reasons why this happens. The first one, which is quite obvious, is that eliminating thermal shocks, we have drastically reduced the expansion of the dies, and thus the formation of cracks. The second reason is that the alloy remains smoother, helping us fill the casting because we work at a higher temperature [...]

By eliminating water from the lubrication process, we have drastically reduced the formation of hydrogen, which causes porosity in the casting. Based on our experience, it is important to carefully assess the mould and know the cause of porosity, which is not always the result of the lubrication process but can be due to internal [...]

Lubricating with water-based products normally take 10-15% of the cycle time. Two-thirds of the lubrication process are dedicated to the mould drying process, which is no longer necessary if you use the Dry Lub System. That’s how we save 7-10% of the time. We can also do better with particularly difficult castings. But this is [...]

A minimum amount of the dry product is applied electrostatically to the surfaces. A light suction is required to remove the fumes that result from the melting process.

The products we use are not toxic and meet all EC parameters.

By eliminating the water-based release agent we have eliminated oil mist and waste water as well as subsequent depurations. Moreover, we have reduced suction-related consumption.

Technically none, because the lubrication head of the Dry Lub System is made specifically for the die casting machine in which it is mounted. Consider that the powder is almost invisible, and the application is really fast.

Our procedure includes manual tests on the moulds being used by our clients. We also check the temperatures using a thermographic camera and analyse the results. The possibility to continue the automated tests is an option we’ll consider at a later stage. This first stage is totally free of charge for the client.
