650 ton Central Locking Toggle 


The sale of Bole Machinery is increasing steadily in recent years with the launch of new EK series [China Unique Producer, Central Locking Toggle" machine. There are obvious advantages in the injection industry under the guidance of leading product technology strategy. With the design of central locking toggle structure of Bole Machinery, there are three main advantages compared with the competitors: a. High product accuracy; b. Less-flashes or no flash; c. 2%-5% material-saving






















1. 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.
