Difficulties And Solutions For Using Screw Caps For Compression Molding Machines

In daily life, the use of screw caps often faces many challenges. When opening, the screw cap may be difficult to open because it is screwed too tightly or adheres to the bottle body, and the contents may leak due to poor sealing.

During the production process of some products, the screw cap is screwed too tightly. For example, some condiments in glass bottles, such as chili sauce and ketchup, may be screwed tightly to prevent leakage during transportation.

If the sealing ring of the screw cap is damaged or aged, or the bottle mouth is scratched or uneven, the contents may leak out from the gap when the screw cap is opened. For example, if the bottle cap of some beverages in plastic bottles is squeezed during transportation, the sealing ring may be deformed. When consumers unscrew the bottle cap, the beverage will leak out from the gap between the bottle mouth and the bottle cap, dirtying their hands or the surrounding environment.

Some screw caps are specially designed and need to be opened in a certain direction and force. If consumers do not understand the correct opening method, the bottle cap may not be fully opened and the contents may leak out from other places. For example, some medicine bottle screw caps with safety locks may damage the cap structure and cause the tablets to scatter if the force is applied in the wrong direction.

High-precision compression molding machines can ensure that the size and shape of the screw caps are highly consistent. By precisely controlling the molding process of the mold, the compression molding machine can ensure the uniformity and symmetry of the nut thread, thereby reducing the situation where it cannot be unscrewed.

Compression molding machines can customize the production of nuts according to different bottle mouth sizes and shapes, ensuring that the nuts fit perfectly with the bottle mouth, and even people with weak hand strength can easily unscrew them.

Compression molding machines can process a variety of plastic materials, including polypropylene (PP), polyethylene (PE), etc. For example, polypropylene materials have good impact resistance and flexibility, which can reduce the possibility of deformation of the nut during tightening.

In the production process, suitable materials can be selected according to different product requirements. For example, for bottles that need to be opened and closed frequently, such as beverage bottles, polypropylene materials with good flexibility can be selected to ensure that the nut can still maintain good sealing and easy tightening after multiple uses.

Compression molding machines can accurately mold sealing rings to ensure that the shape and size of the sealing rings meet the design requirements. Through high-precision molds and molding processes, high-quality sealing rings can be produced, thereby improving the sealing performance of screw caps.

The compression molding machine can design complex mold structures according to different product requirements. For example, a screw cap with a spiral sealing structure can be designed to increase the sealing area between the screw cap and the bottle mouth, thereby improving the sealing performance.

During the production process, a suitable sealing design can be selected according to the characteristics of the product. For example, for some products that need to be stored for a long time, such as food bottles, a screw cap with a spiral sealing structure can be designed to ensure the sealing and shelf life of the product.

The compression molding machine can improve the processing accuracy of the screw cap, optimize the material selection, improve the quality of the sealing ring, optimize the sealing design, and optimize the capping method.
