Overview of the packaging process
The flow generally splits in two: steps before plastic encapsulation are front-end; steps after moulding are back-end. Moulding runs in a clean environment, because transfer moulding presses and preform dust exceed Class 1000 (more than 1000 particles ≥0.3μm per m³).
Most packaging materials in use today are polymers, i.e. so-called plastic packaging. As shown above, there are many plastic moulding techniques, including transfer moulding, injection moulding and pre-moulding; transfer moulding is the most widely used.
