Development of a Thinwall Product for Injection Moulding

The benefits associated with decreasing wall thicknesses below their current values are still measurable and desired even if the final wall thickness is nowhere near those of the aggressive portable electronics industry. It is important to note that gains in wall section reduction don’ t always occur without investment, in this case, in tooling and machinery upgrades. Equally important is the fact that productivity and performance benefits of reduced material usage, fast cycle times, and lighter weight can often outweigh most added costs. In this work, various designs of thinwall plastic product were developed with usage of CAE tools. During development process special attention was put on the choice of material. Also, simulation of injection moulding was conducted in order to avoid potential moulding problems. Results gained from the simulation were used for the optimization of an existing product design, for mould development and for optimization of processing parameters, e.g. injection pressure, mold cavity temperature, etc.
