STACK MOULD is a small
and high precision product
and it is used up in massive
amounts.
The productivity is enhanced
sharply in audio· video
tapes, CD , DVD, Cup and
disposable receptacle moulds.
The plastics are reduced.
The efficiency of the injection
machines is enhanced. Full
automation is possible.
Considering all of these
advantages, this is high
value-added mould contributing
to cost saving |
