Cockpit in magnesium thixomoulding
Project Manager M.C.S. Facchetti: Fabio C.
Client
Multinational German company operating in the aluminium and magnesium alloy die-casting sector
Customer's requirement
Making a mould to perform 300,000 strokes under warranty, with thermoregulation/ operating temperatures above 300 °C.; the piece produced is free from mechanical processing with tolerances of shape and position within a few hundredths of a millimetre.
Equipment made
Open-close two-cavity mould, with extraction from the fixed side, especially designed for production using thixomoulding from magnesium granules.
Solution of critical issues
Through fine tool manufacturing to comply with the required tolerance range and implementation of extremely complex and articulated temperature control circuits with third-level simulations of the thermal expansion of the mould being produced. The simulation software was also adapted to the specific situation, involving the injection of the magnesium alloy under thixotropic conditions.
Case history
View all
Achieving a visual quality of filling of grade A fins to meet painting requirements with no visual defects on the final product, as well as eliminating the need for machining on gasket seats.
Obtaining a piece with extremely critical massive areas for volumetric shrinkage porosity, leak-tested with shell test and channel test of water and oil circuits.
Industrializing and building a new type of agricultural container with low weight, using muCell® technology, never applied and validated before for solutions of such dimensions and structural characteristics. Therefore, creating the 3D piece that meets these requirements, together with the resistance to the stresses required in stacking at full load, handling and use with third-party systems.
MCS Facchetti, with a constant focus on innovation, has carried out in-depth studies of new technologies designed to be applied to giga castings, with satisfactory results.
