Features Of The Internal Thread Structure Of The Cap

The matching of the cap and the hollow bottle requires no leakage, good tightness, and a complete (continuous) internal thread structure. Considering the use of forced demolding will lead to difficult demolding, the internal thread deformation is large, if the movable thread core is used to manually dethread outside the mold, due to its low production efficiency string, it is difficult to apply the requirements of large production batches. After analysis, an automatic thread removal mechanism is adopted.

The upper part of the cap is for easy dry carrying. The large hole of 4520 and the 8 small holes for installing the hanging rope or hammering decoration are designed, and the machine is formed by the side core pulling mechanism, and the bottle cap structure is complex.
