One of the main themes for study and analyse, when it comes to optimisation, is the reduction of the weight of a part or assembly. The immediate and intuitive solutions are related to the modification of the geometry or material.
But what is left to be changed when there are already constraints related to the modification of the geometry or material? In their search for a solution, the engineers have thought of the aerated chocolate model.
Whereas the aerated chocolate has been introduced by Rowntree’s, in 1947, the MuCell injection moulding technology appears relatively recently, in 1974, described in an US patent, named Mixing melted plastic with gas.
