Each brand of mineral water bottle cap has its own thread. Today we will follow the mineral water bottle cap manufacturer to briefly understand the analysis of the thread. Don’t miss the exciting content below!

1. Rotating deep thread

1. During the injection molding process, the rotating equipment system in the mold can effectively maintain the integrity of the cap screws. Therefore, the thread shape of the bottle cap can be effectively manipulated, and the bottle cap wall will not be skewed when the threads of the upper bottle shank are rotated.

2. During the process of screwing the bottle cap, rotate the upper bottle shank thread so that the bottle pad is close to the bottle wall, which can convert the bottle cap into a linear force.

3. Since the threads of the rotating teeth cannot effectively prevent the cover gasket from falling off, the screw cap should be glued and posted when adding the gasket.

2. Strong break of shallow line

1. During the injection molding process, the bottle cap can be easily demoulded from the mold without the need for mold rotation. Obviously when planning the thread of the bottle cap, the thread must be shallower so that it can be "strongly demoulded" during the injection molding process. , and there should be enough moderate threads to cover the bottle wall threads perfectly.

2. Strong thread bottle caps can be posted without adding glue when adding the inner tank. The inner tank can be effectively constrained by the threads, making the cap gasket less likely to fall off.

3. When you want to add multiple layers of lining to the bottle cap or make various possible solutions for the bottle cap (such as thread-blocking caps), you will generally choose forced threading.

4. Forced tripping threaded caps have restrictions on raw materials during the injection molding process, among which polyethylene and polypropylene materials are popular choices.

The threads of mineral water bottle caps have the above two types of analysis. I hope the above content can be helpful to you. For more news and information, quickly move your little hands and pay attention to Anhui Hengzheng Packagingscience and technologyCo., Ltd. official website!
