Features：
1, with short length and compact structure, the whole machine
occupies less floor space.
2. Dispense with mould adjustment, it is more convenient and faster to change
the mould.
3. with large opening stroke and colossal spaces between bars.
4. with elegant appearance.
Clamping System: 
1. Direct-press type of clamping structure with high-precision
pressure pick-up ensures accurate clamping forces.
2. Four bars are exerted equal force and have short stress segment; it brings
the clamping units good rigidity and long life expectancy.
3. Finite-elements-analyzed and optimized mould has good rigidity and small
deformation.
4. Oblique cylinder with rapid mould movement.
5. Dispense with mould adjustment, it reduces machine wear.
6. with multi-ways of hydraulic ejector system.
7. Automatic centralized lubrication system.
Injection System:
1. With double injection cylinders, it makes injection movement
more stable.
2.6 staged injection, 5 staged pressures maintaining, 3 staged pressures and
speed control in pre-plasticization.
3.2 Ways of initial control for pressure maintaining (location, time).
4. With anti cold burden start function.
5. We use large-toque oil hydraulic motor as pre-plasticization device.
6. Screw rotary speed detection devices.
7. Differential injection function increases the injection speed.
Hydraulic System 
1.
With multi variable pumps & closed-loop control, the system is more energy
saving.
2. Unattached high pressure oil pump can create clamping forces of high
pressured rapidly.
3. Imported hydraulic parts and seal components.
4. Bypath oil filters of high-precision.
Safety System:
1. With anti-pinch injury function, it is speed- adjustable to
open or close the electric security gate.
2. Nozzle Injection protective cover can prevent plastic material ejected.
3. Double safety protection systems of hydraulic and electric interlock.
4. With safety tread inside and outside of mould, it protects personal safety.

Note:
．Theory injection capacity = screw
diameter2×π/4×screw travel
．Actual injection capacity is the maximal weight of polystyrene (
PS ) raw material injected to air.
．When UPVC, PC, PMMA, PA and other engineering plastic material
are used, please let us know. When you need modifying parameters and functions
of the machine, please let us know also.
．According to demand of machine upgrade, we will change technical
parameters, configuration of some parts and service’s items without prior
notice.
．Photos are for reference only. If there is any difference with
actual products purchased, the real products are final.
．In normal condition six months warrantee for barrel & screw;
But using caustic or any recycling material is not is guaranteed.
