Alluminium – Magnesium


The Fondvacuum® valves guarantee maximum air suction and duration, with reduced need of maintenance. with proper usage, they can be used for approximately 20,000 cycles without maintenance.

Modern diecasting faces critical procedural issues – such as the reduction of the refuse caused by porosity. Porosity can have different root causes, such as air incorporated during the injection process.

Internal porosity can have dimensions ranging from a few microns to a few millimeters, causing subsequent poor surface quality that can be seen during the extraction and even after thermal surface treatments.

The presence of air also creates a counter-pressure generated in the filling phase, which can cause cold joints or incomplete fillings.
