F2v Series

Main Features：

High rigidity design reduces deformation of clamping unit 
Special heat treated toggle equipped with steel sleeve en
hances abrasion strength
New multi-point supporting design reduces the deformation 
of carriage injection unit
Energy-saving and quick response hydraulic circuit design
High speed Duo-CPU control system

Clamping Unit

Compact space saving toggle mechanism design 
Finite Element Analysis ensures all platens key structural 
components for their maximum service life and best moulding results

Advanced stress analysis software are applied to design of 
tie bar and screw

Stable mould closing, opening and adjustment

The ejector cylinder plate together with movable platen form 
a single piece of casting. This improves rigidity of both ejector 
cylinder support and the platen
 

Increased ejector stroke and robustness of cylinder support 
specific for long hollow plastic parts


Hydraulic system


BOSCH-REXROTH Proportional pressure valve and flow valve 
fitted in our machines improve the control precision 

Adoption of vane pump that matches with proportional 
flow valve and pressure valve, improves the control accuracy 

Individual pressure valve adjusts the range of pressure 
the control precision 

New design of hydraulic circuit, easy for maintenance 
Saving about 30%~50% of electricity compared with 
standard fixed vane pump 
Low heat occurred hydraulic system and 30% cooling water 
quantity can be reduced

Bypass filter device will ensure the hydraulic oil in a 
high cleanliness
Low Energy Consumption
The variable displacement pump surpasses conventional 
fixed vane pump in terms of energy consumption. Output 
of the variable displacement pump varies according to 
load requirement and flow rate, whereas output of fixed 
vane pump is constant. According to the analysis in the graph, 
the average reduction of electricity consumption30%~50% compared 
to conventional fixed vane pumps. This feature implies 
undisputable benefits in today`s cost conscious and 
environmentally aware world that we live in.

Injection Unit

Creative design of injection unit 
High flexibility to match and change different diameter 
screws

Diagonal layout of carriage cylinder to balance the 
supporting force (about 90Fv2) 

Screw and barrel are made of high quality new materials,
improved their working life
Anti-wear bushes are replaced by copper bushes, which 
improve the lubrication result
