The utilization efficiency of locking force is 10% -20% higher than that of fixed structures;
Compared to before (less flying edges);
Product thickness standard, saving 2% -5% material compared to traditional structures; <①>
Effectively protect molds, templates, and pull rods;
The mold opening stroke is 10% -20% longer than traditional structures.
According to a sampling survey conducted by Bole, compared to traditional inward turning machines, the central locking mold structure can save 2% -5% of raw materials for 80% of molds.

The locking force of traditional structures will be lost, with a utilization rate of only 80% -85%;
Moving the template will cause deformation, resulting in flying edges and wasting manpower and materials.
