The client asked for a mould of a monocoque polycarbonate chair for interiors. Collaborating with the designer
we made the product industrialization modifing the 3D model to allow the chair mould. Then we made a structure
calculation FEM to verify the structural resistence and the Mold Flow to verify the uniform inflation.
The mould is composed by three main parts: the injection part, the extraction part and a central mobile male
to allow the single block extraction of the chair.
Considering the big plastic mass of the item, necessary to satisfy various needs, aestethic and structural, we inserted two injectors in order to use the gas inflation technology.
