Preform Injection Mold from 1-cavity for wide mouth jar
and gallon bottle perform up to 72-carrow neck perform
mold; 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
tempera-ture control of each cavity;
Lip cavity is made of imported nitrated steel, which is
of high hardness and long service life, in accordance
with international standard;
The 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 improves greatly of the plastic product quality;
No cutting of gate is employed to reduce the labor intensity;
Standard inter-changeable mold components;
The life of mold is more than 3 million times.
I.Off-center Adjustment System
Off-center adjustment system can make the error of preform’s
wall thickness less than 0.05mm. This system does not
affect the lifetime of mold;
II.Self-lock System
International advanced bi-awls fixed orientation self-locked
structure has been adopted.
III.Cooling System
All the water Channels in the mold’s each inner part,
which make the cycle time short enough. And all the cooling
channels have been specially treated to prevent them from
jam;
IV.Heating System
Double Heating System can ensure that the impact of heating
is good and quality control is credible. The Heating Band
unit makes nozzles be with invariable temperature. The
Heater Unit is used to heat the hot runner plate with
long using life and powerful heating capacity.
V.Hot Runner System
The perform mold adopt Pin-valve type Hot Runner System,
such hot runner system can reduce mold’s each part’s wear
& tear and maintenance cost, and also save 10%~15%
electric energy;
VI.Hydraulic Ejecting System
The perform-doffing success ratio has achieved firm endurance
and the whole perform ejecting process will become much
quieter.
