and dies are very expensive to make, and if they are not designed
correctly they can be equally expensive to modify. Tool designers
are expert in designing for various types of polymer moulding, injection,
blow moulding, extrusion moulding and thermoforming. All these processes
have particular requirements and settings for each different part.
Analysis can prevent problems by identifying them before they arise.
Using process simulation software it is possible to predict the
behaviour of the polymer in the mould before any metal is cut. This
means that the design can be changed instead of the tool –
a much cheaper option.
Our associated companies provide a complete range of injection moulding
process simulation services. The analyses available are: Filling
Analysis, Runner Balancing, Packing Analysis, 2D Cross-Sectional
Cooling Analysis, full 3D Cooling Circuit Analysis, Shrinkage and
Warpage Analysis, Co-Injection, Cascade Injection Moulding, and
Gas-Assisted Injection Moulding These analyses will help identify
moulding problems such as unbalanced cavity filling, gas traps,
weld and meld lines plus excessive filling pressures and melt front
Software Showing Potential Problem Areas.
Element Analysis can predict whether or not a part or whole product
will fail to meet Australian Standards. It will identify excessive
stresses, strain, and deflection. It will also show if too much
or too little polymer is being used. This helps reduce and optimise
material volume usage. FEA can also describe polymer visco-elastic
behaviour such as creep in the analysis, as well as impact loading
and design for elevated service temperatures.
prepares the brief to guide the analysis and then interprets the
results for our clients and ensures that the recommendations are
incorporated in the tool designs.
