What is meant by part optimisation?
A part optimisation can be carried out on the basis of the findings from an injection moulding simulation of the actual state.
On the basis of sections and pictures we develop proposals for part optimisation, gate design and temperature control (see also HeiNo® standard elements). TThese are implemented via various measures and will be verified using further injection moulding simulations and FEM analysis.
- Process optimisation
- Optimisation of geometry, material, flow behaviour, feed, holding pressure etc.
- Near-contour temperature control
- Separate temperature control inserts against “hot spots”
- Separations / modules for ventilation
- Negative correction
- Alternative production technologies
- Reduced cycle time
- higher part quality
- Faster project cycle
- Larger process window
- Reduced warpage
- improved shrinkage compensation and wall thickness ratios
- Fewer part defects
Component optimisation is possible, for example, in the fields of wall thickness ratios or rib/lid wall ratio. On the other hand, filling aids or reductions of material in corners can be used. If necessary, a calculated negative correction is made or, in the case of glass fibre-reinforced components, a measurement is determined. In this way the best possible result for the article geometry is achieved.
Furthermore, after optimization, all necessary specifications regarding gating, temperature control, heating times (e.g. rubber) and separation are available.
This allows the tool design to be carried out very quickly and on a secure basis.
In order to optimise the part, readable solids, data of surrounding parts and exact material name with rheological and mechanical data are required.
