440 ton plastic mold machine 




1. EKII series center clamping structure obtained the national invention patent of China





Fully optimized hydraulic system, efficiency 10% higher than last series( Standard EK) .


Hydraulic parts from famous international manufacturers, ensure machine with reliable performance.


Conform to GB, CE, UL. KCS or other safety standard.







2. Product Instructions










Bole centre clamping structure
100% clamping force use, 10%-20% higher than traditional toggle structure.
Less possibility of flash, save flash trim work.
Save 2-5% material.
Offer good protection to mould, platens and tie bars.
Opening stroke 10-20% longer.


 Traditional structure
With heavy clamping force waste, only 80-85% efficiency.
 Moving platen with obvious deformation, cause flashes, waste of material and labor of trim the flashes.
