Bottle Cap Mold

Bottle Cap Mold Details

Overview of bottle cap molds

The "bottle cap" is a plastic component that can be seen everywhere in daily life. There are various styles and colors of bottle caps, but commonly used beverage bottle caps are cylindrical with threads on the inner side and anti slip ribs on the outer side. Its main function is to seal the mouth of beverage bottles, making it easier for people to store beverages. In industry, bottle caps rely on "bottle cap injection molds" to achieve mass production.

Design mode of bottle cap mold

As a packaging container for mass production, the bottle cap should adopt the design mode of the first mock examination with multiple cavities. Based on the clamping force of the injection molding machine, the injection volume, the precision and economic factors of the bottle cap, it is determined that the bottle cap is one mold with multiple cavities, and the cavity arrangement is "straight line".

Design process of bottle cap mold

1. Determine the structure of the bottle cap: The structure of the bottle cap is a prerequisite for mold design. The structure of bottle caps should be determined based on actual application needs and market demands, such as cap height, bottom diameter, thread specifications, etc.

2. Drawing of the mold: According to the structural requirements of the bottle cap, preliminary drawing of the mold should be carried out, indicating the upper and lower molds of the mold, and then drawing should be carried out separately for each component.

3. Determine mold parameters: Based on actual needs, determine mold parameters such as upper mold weight, lower mold weight, mold size, etc. to ensure stable operation of the mold.

4. Mold casting: After completing the mold design, appropriate materials are selected for casting, and the completed mold is quenched to ensure its hardness and wear resistance.

5. Processing: After the mold casting is completed and quenched, post processing is required to finely process the mold to ensure its accuracy and precision.
