If an integration of electronic, optical and mechanical functions is realized in one part, the part is called MID part.
MID is short for the term Molded Interconnected Device. In a newer description, MID is also referred to Mechatronic Integrated Device.
When it comes to injection molding, a part is produced using a thermoplast with additives. With this, the optical and mechanical properties are defined.
After the production, there is a second step (e.g. using the LDS process) in order to activate the additives. This is important to allow metallisation of the part in a third step.
The metallisation is used to create the circuit lines in order to prepare the base for mounting SMD elements for completing the electrical function of an MID part.
Besides this, the MID technology is widely used in creating antenna for mobile communication.

A leading software for simulation of plastic parts is Moldex3D from the company Coretech System.
It helps e.g. to validate the part design, balance the filling, choose the correct machine, check the cooling layout and warpage prediction.
The results can be exported directly to a structural mechanics program.
The 3D meshing allows simulation of other applications like GAIM/WAIM, Foaming and ICM, next to the traditional injection molding.

The usage of the free Moldex3D Viewer software is necessary to look at the results from Moldex3D injection molding simulations.
It is possible to check the used materials and process parameters.
Furthermore, different views, slicing, iso-surfaces and different scaling help to interpret the results correctly.
Animations and screenshots can be easily created for presentations in this software.

As one of the first simulation tools for the injection molding process, the software Moldflow was commercially available.
The company with the same name as the software was founded 1978 by Colin Austin in Melbourne, Australia.
The first calculations where done using simple formulas on plates and cylinders. Soon, the use of FEM technologies and the computation on a midplane model followed.
Based on that, the part adviser, fusion or dual domain technology was developed and implemented in the simulation. Consequently, the simulation technology was further developed into a full 3D approach covering the simulation of the injection molding process as well as all related processes.
Autodesk acquired Moldflow in the year 2008. Since then, the software is known as Autodesk Moldflow.

Reactive, chemical connections, which exist separately are called monomers.
Monomers are low-molecular and will be combined by a chemical reaction to branched or unbranched polymers.
Most monomers do have a C=C double bond.
Plastic melt might contain residual monomer. At higher temperatures, they will evaporate, which can be realized in many cases by its smell.
