Magnesium die-casting
Magnesium die-casting
The lubrication stage is extremely important during the Magnesium production cycle. Besides the problems caused by swarf, lubrication with water-based release agents can also result in problems and potential danger. That’s why you need to pay special attention. The demand for magnesium artefact is growing. However, fears related to this type of alloy limits its expansion. A lot has been done to increase safety both on hot and cold chamber die-casting machines and relative furnaces, but a few issues are still to be solved.
The DRY LUB SYSTEM can make work safer and improve the quality of products, thus solving these problems. Our dry lubrication system does not require water-based release agents nor the drying process. It increases the fluidity of the alloy and drastically reduces porosity and cycle times. Bring new life to magnesium die-casting with our DRY LUB SYSTEM.

How the DRY LUB SYSTEM works
A minimum amount of dry lubricant – about 0.3-0.5 grams for each kilogram of injected magnesium – is electrostatically applied to the mould at each production cycle (these consumptions were calculated at a mould temperature of 250 °C). When it comes into contact with the hot mould, the product distributed electrostatically melts, expanding to the deepest points. This way, it creates a highly efficient release film, without creating residual thickness and carbon formations, which are typical of water-based lubrication systems.

Initial tests are free of charge. Then a fee is asked if you want to proceed with automatic systems.
Carrying out manual tests during the normal work cycle, detecting the temperatures of the moulds, and assessing the efficiency of the DLS with our clients are part of our procedure.
As already mentioned, the drying stage is extremely important. By eliminating water, we have eliminated even that minimum amount of humidity, which is the first cause of porosity.
When it comes to magnesium die-casting, the moulds take about 15 to 20% of the cycle to dry. By saving this time, we automatically increase productivity.
Thanks to its chemical characteristics, the powder release agent ensures excellent release, increases mould filling speed, and reduces metallisation.
The powder lubricant is applied electrostatically. This system allows you to spread a micro-layer of product across the die surface evenly and extremely safely.
The powder applied for lubrication is hot-melt type and it melts when in contact with the mould.
