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
