Advantage of Central locking sturcture  (sales points)

1, 100% clampping force use ratio.10%-20% higher than tradtional one
2,  Less fins on the finished products
3,  2%-6% raw material saving on the production   (deeper cavity more, save more material)
4,  effective production for the mold.Mold board and pull rod
5,  Open stroke 10%-20% longer than tradtional one
6,  Less deformation after cooling


Shortl spacking.......
1, Bigger clampping force,  Use smaller machine make bigger productes
2, Bigger Open stroke,  Very suit for deep cavity product
