What is meant by an injection moulding simulation?
INJECTION MOULDING SIMULATION
An injection moulding simulation shows the process of filling and cooling (thermoplastics) or cross-linking (silicone/rubber) with the influence of the mould (e.g. temperature control and injection situation) even before the mould is designed.
Qualified simulation and the expert interpretation of the results allow possible moulded part and tooling defects to be detected at an early stage. This is the basis for component optimisation.
Fundamentals of the injection moulding simulation
The combination of an injection moulding simulation of the actual state, a view on the simulation of a temperature control of the future mould, the component optimisation and the subsequent simulation of the optimised state with regard to component and temperature control does not only enable very precise simulation and optimisation results.
The fact that the most important influencing variables can be included in the development of the product means that the first samples can already be produced with good parts more and more frequently.
Since the geometric part optimizations generally also enable a significantly shorter cycle, the previous additional effort pays off several times over. The time to the finished product is significantly reduced, quality is improved and the unit price is also lower due to a better process window with a shorter cycle time.
After the part optimisation has been carried out, the possible cold and holding pressure stresses, and thus the distortion, are reduced. Now, if necessary, a negative correction of the part can also be made. We create these in compliance with the tangential contour transitions. This manipulated geometry is then worked into the tool so that warpage is reduced to a minimum.
