Demark pet preform injection molding system uses a new part
cooling and handling system, which features:
1. Cooling on the inner surface of the preform without using
compressed air, unlike most post-mold cooling systems which only
cool the outer surface
2. Optimized cycle utilization — being mounted on the moving
platen, the cooling system remains active for up to *5% of the
overall cycle.
Demark pet preform injection systems are available from **0 to
**0 tonnes (***0 to ***0 kN) and up to *2 cavities.
Demark pet injection systems offer:
1. Faster cycles(*0 second)
2. Reduced energy consumption
3. Smaller footprint
4. Improved repeatability
5. Rapid set-up
PET Preform Mould from 1 cavity for wide mouth
jar and gallon bottle preform up to *6 cavity narrow neck preform
mould;
Tube blank is designed with the help of computer, which surely
contributes to the increasing of yield of bottle;
Employed internationally advanced two-step dual taper locating
technology. Each cavity self-locks independently to ensure low
decentration of product;
Core and cavity are made of special mold steel after preheating
treatment in the original factory in Sweden. Individual temperature
control of all cavity;
Lip cavity is made of imported nitrated steel, which is of high
hardness
and long service life, in accordance with international
standard;
The excellent hot runner design assures uniform heating and
greatly improves the quality of plastic product;
No cutting of gate is employed to deduce the labor
intensity;
Standard inter-changeable mould components;
