There is often a need for some kind of plastic enclosure or other plastic part made specially for some PCB
After the first, rough PCB layout, a 3D drawing is made in SolidWorks® of an enclosure which fits the PCB.
We then print this enclosure in 3D as a prototype to verify that everything fits correctly before submitting drawings for the plastic mould.
We can even print a replica of the PCB if it must fit into an existing cabinet.
We can also make stress testing on plastic parts.
