Food packaging is increasingly being produced using multiple moulds and stack moulds.
Especially the manufacture of stack moulds requires a great deal of experience and understanding the art of injection moulding.
- An important factor is the construction. If the mould is designed correctly, its lifespan will be no less than a single mould. A correct heat regulation plays a very important role in determining how reliable production will be.
- A second determining factor for a good stack mould is the precision with which the components are made and assembled.
- Stack moulds are customized, not readymade, because the mould is adapted to suit the injection moulding machine.
- The gate plays an important role. The leak-tightness and balance in the gates are essential.
