Two-platen Large Injection Moulding Machines
Features of Two-platen Large Injection Moulding Machines
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.
Control System
- High resolution LCD screen with optimized panel layout for convenient machine operation.
- High speed CPU increases capacity for memory to meet the requirements of system control.
- 200 sets of moulds information storage. SD card/USB input for large-scale production management.
- Network communication port to achieve the fully automation of production.
- Auto detect the injection status to make sure the machine running correctly and products normal data.
- Machine can be stop by forming numbers.
- Mould auto adjucting with clamping force.
Clamping System
- Direct-press type of clamping structure with high-precision pressure pick-up ensures accurate clamping forces
- Four bars are exerted equal force and have short stress segment; it brings the clamping units good rigidity and long life expectancy
- Finite-elements-analyzed and optimized mould has good rigidity and small deformation
- Oblique cylinder with rapid mould movement
- Dispense with mould adjustment, it reduces machine wear
- With multi-ways of hydraulic ejector system
- Automatic centralized lubrication system
Injection System
- With double injection cylinders, it makes injection movement more stable
- 6 staged injection, 5 staged pressures maintaining, 3 staged pressures and speed control in pre-plasticization
- 2 ways of initial control for pressure maintaining (location, time)
- With anti cold burden start function
- We use large-toque oil hydraulic motor as pre-plasticization device
- Screw rotary speed detection devices
- Differential injection function increases the injection speed
Hydraulic System
- With multi variable pumps & closed-loop control, the system is more energy saving
- Unattached high pressure oil pump can create clamping forces of high pressured rapidly
- Imported hydraulic parts and seal components
- Bypath oil filter of high-precision
Safety System
- With anti-pinch injury function, it is speed- adjustable to open or close the electric security gate
- Nozzle Injection protective cover can prevent plastic material ejected
- Double safety protection systems of hydraulic and electric interlock
- 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 guaranteed.
