It’s one of the key points for molding excellent plastic crates. As we all know that the nice material for durable and strong crates usually is in low MFI (4 or even 6), which requires higher on hot runner system.

And sometimes, if it is one-off crate, recycle material would be optional for reducing the cost for manufacturers and users. So for this, there would also be different design of hot runner system to avoid damaging cavity and core by the small iron piece and the pebbles.
