During the filling of the Furniture Mould(FURNITUREMOULD) https://www.furnituremould.com/ , the advancing polymer movement creates a high wall force on the high punch to form deep or long holes. These forces can punch or bend the punch and change the cast parts. In tough environments, this bending can fatigue the custom mould metal and destroy the punch.
The duration of the punched surface determines the most commonly used ratio. Correctly interlocking punches are generally better able to withstand deflection than punches that only kiss. A single punch for the through hole can be directly interlocked into the reverse furniture mould part for maintenance. A mismatch can reduce the size of the opening in the hole created by the assembly punch. The blueprint allows creating a larger punch. There are many mismatched uniforms that can retain the required hole diameter. Tight tolerance holes that cannot be stepped may require interlocking characteristics with respect to the punch to accommodate slight misalignment.
These features increase furniture mould manufacturing and storage costs. In a quick through hole that can be cast with a single punch, a spherical side on one wall of the hole eliminates the mating punch and prevents a mismatch.
