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
