Description of Preform and cap 90T 130T 180tons injection blow molding machine
Features of of BL-1800 Preform and BL-1400 cap injection molding machine:
High precision
BL-1800 injection molding machine adopts full digital closed-loop
control, with high precision, pressure can be accurate to 0.3bar,
and flow is stable, especially when the flow is low, the advantages
are more obvious. It adopts permanent magnet synchronous servo
motor and special servo drive, with fast response speed, the
response time is only 60m at 0-maximum flow, and about 100m at
0-maximum pressure.
Low oil temperature
The BL-1800 injection molding machine has no magnetic flow loss, so
the oil temperature is the lowest compared to limited pump or
variable pump memory. Furthermore, the use time of the hydraulic
oil is fully extended, the wear of various seals is reduced, and
the amount of cooling water is saved at the same time.
Low noise and long life
The internal gear pump imported from Germany is precise and stable.
It has the advantages of small internal leakage, long service life
and low working noise. Compared with ordinary fixed pump models,
the noise is reduced by 20 decibels on average.
BL-1800 Servicing Energy-saving Adjustable Hydraulic Volume
Injection Molding Machine
This machine adopts energy-saving devices such as motors with
excellent performance; sensitive servo control system, quick
start-up reaction time only needs 0.04S; servo motor and hydraulic
system form a closed-loop control, which greatly improves the
molding repeat accuracy compared with traditional injection molding
machines; reduces power usage , Under ideal working conditions,
this model can save electricity by 25%~80% compared with
traditional injection molding machines; the noise of the whole
machine is lower when it is running, which is significantly lower
than that of traditional injection molding machines.
1. Electronic control system
1. It is equipped with advanced professional computer controller
for injection molding machine, and the whole machine control system
adopts full digital control, which has good controllability and
high reliability;
2. Optimize the superposition and switching methods of the system
power combination to maximize energy saving and improve response
speed;
3. The software function is more powerful, and the injection
molding machine has good scalability. It can provide expansion
support such as gas-assisted and manipulator.
4. Built-in multiple sets of mold forming process parameter access
system, which is convenient for the factory to manage the molds,
can realize the rapid transfer of mold parameters, and the
production preparation is high-speed and efficient.
2. Mold clamping system
1. The inwardly rolled five-point elbow elbow clamping mechanism
can provide a strong clamping force in a short time
2. Increased internal spacing of tie rods and mold shifting stroke
allow larger and deeper molds
3. Hydraulic motor drives automatic gear adjustment
4. Adjustable movable formwork support structure to reduce the
load-bearing deformation of the tie rod
