Usually, Multi-cavity pet preform mould does use the hot runner
system rather than cold runner system, so the design of hot runner
system plays an important role in mould quality guarantee. Based on
foreign advanced techniques and combined with domestic clients
demand, we adopt the valve gated design, in which each cavity has
its own heating zone and temperature is measured by independent
thermocouple.(advantages: easily avoid some problems such as white
or drawbench on bottom). Here, Mould is produced automatically to
reduce labor force.
Main mould components (die core, die cavity, screw neck) are made
by injection process, and the material of which originates from
Sweden high-quality mould steel (HRC 45).In this way, it is no
doubt that the mould can be used for 2 million shots without any
maintenance, meanwhile, the wall thickness between max. part and
min. part is not more than 0.05mm; turning center processes make
sure that every parts can match well; proper distribution of
cooling water way improve productivity effect and molding cycle
only takes 15 seconds( need proper water chiller, bottle design and
injection machine)
Our mould, designed and developed by our engineers, is of high
precision and long life span without traditional problems. In a
word, Preform wall thickness is on error of 0.05mm; weight
difference is less than 0.3g; 2-5 moulds per minute; 2 million
guarantee; utmost 144 cavities in one mould.
Main feature:
1.Mold cavity from 1 up to 144.
2.Electric control system with simulating stretch testing improve
yield rate.
3.Adopt world advanced dipole taper localization technique, each
cavity self-clamp independently, ensure mould concentricity.
4.The material of mould die core and die cavity are made of Sweden
special mould steel.
5.International standard screw neck, imported nitrided steel with
high hardness is of long usage.
6.Advanced hot runner design and even heating temperature make sure
the high quality of plastic products.
7.Valve gated type without tail reduces labor force.
8.At least 2 million guarantee.
