of die casting aluminium moulds
To analyse the procedure for the manufacture of moulds for aluminium die
casting it is important to mention both parts of a die casting mould:
- the fix part which is installed on the fix plate of the press;
- the mobile part which is installed on the mobile plate of the press.
In some case it is necessary
to build proper slides/inserts in order to obtain particular figures or
back drafts of the part.
In the manufacture of moulds for aluminium die casting following elements
have always to be considered:
- form and dimension;
- mechanical and thermic shock;
- features of the press that has to be used.
The phase of development of moulds
for aluminium die casting starts when the producer receives the manufacture
order together with the final drawings and the technical specifications
of the project.
The producer engineering staff prepares a draft of the 2D project which
is sent to the customer for the approval.
Once the customer has approved the whole project the producer has to prepare
the bill of materials. If there are improvement proposals, modifications
or unclear dimension the producer’s engineering staff contacts the
customer to agree the best solution.
The manufacturing phase
is now beginning: the 3D project (matrixes, inserts, pins and blades)
is prepared and the drawings are 100% checked.
The engineering staff has also to draw a bill of the normalized materials
that have to be ordered and the 3D project of the electrodes has to be
