We always pay attention to the technical innovation and development of bottle cap molds. We have developed and manufactured a variety of bottle cap molds with excellent quality and a wide variety of water bottle cap, beverage bottle cap, cosmetic bottle cap etc. Quality control are required to ensure that the produced mold can finally meet all the requirements of customer production. Therefore, we usually start from five aspects:
We have experienced mold designers using advanced software for bottle cap mould design. The designed plastic mould has the advantages of rapid cooling, high efficiency, easy processing, simple operation and maintenance.
Since the bottle cap mold works for a long time in a high-speed injection molding environment, the plastic bottle mold must use high-strength die steel. In general, the mold cavity and core of the bottle cap mold are made of S136 or 2316, which has the advantages of fine polishing, high hardness and corrosion resistance.
Choosing an excellent hot runner system ensures a balanced and stable injection of all gates in the mold to produce a better bottle cap. Taking into account the convenient replacement of later mold-related accessories, we can provide a variety of brands of hot runners for customers to choose.
All mold parts are completed by high precision CNC tooling machine, high-precision lathes, electric sparks and slow wire electric sparks. In order to achieve its accuracy requirements, all of our tooling machine are imported. After each machining process is completed, the template and mold parts must pass the inspection by the quality inspection team before entering the next machining program. This ensures that the accuracy of the mold is met and unnecessary rework time is avoided.
Prior to shipment, each bottle cap mold was run on machine to further test its quality to ensure long-term efficient operation of the mold after it reached the customer’s facility.
It is with this refined product quality concept and closed-loop quality control that the quality of bottle cap moulds is guaranteed.

The anti-theft caps are tamper evident and possess a special tear off ring at the bottom or side wall which separates when container opens for the first time and required to be easy for the consumer to open.
1. An annular anti-leakage ring is arranged on the inner wall of the top end of the bottle cap;
2. The lower end of the cap is connected to an anti-theft ring by a tension rib;
3. At the same time, a plurality of sheet-shaped revolving tension wings are evenly distributed on the inner wall of the anti-theft ring. This design cap has the advantages of firm sealing, leakproof and anti-theft performance, safe and convenient to use.
For anti-theft cap mould manufacturer, the anti-theft ring usually needs a slide to achieve. We need to ensure the hardness of the slider steel, to ensure the processing accuracy to prevent the flash. We recommend using hot runner for the mold, also cold runner is workable.
Plastic anti-theft bottle cap mould are commonly used packaging forms for bottle packaging mould, especially in the field of beverages cap mould. They can be divided into aerated beverage caps and non-aerated beverage caps according to their uses. Generally, polyolefin is used as the main raw material, which is processed and formed by injection molding and hot pressing. Plastic anti-theft bottle caps are required to be easy for consumers to open, and to avoid leakage due to poor sealing performance. How to properly control the sealing performance of bottle caps is the focus of online or offline testing by production units.

We can now make two types of cap molds, injection cap molds and compression bottle cap molds. The injection molding process is achieved by using injection molding machines and injection molds to shape the caps; The compression bottle caps is formed by compression molding machine and the mold.
When comparing injection molding and compression molding, it’s clear that while compression molding offers advantages such as fast color changes and lower energy consumption, injection molding is a more versatile and efficient process overall. Injection molding provides design freedom and production flexibility to meet the needs of most beverage brands and converters.
Injection cap mould cavity and core of the plastic bottle cap mold is made of high-quality mold steel, and the guide sleeve of the mold guide column is lubricated without oil, which has the strong advantage of no pollution and a service life of up to 3 million shots.
Each cavity of the plastic bottle cap mold is self-locking independently, which can ensure the concentricity of the mold. The excellent cooling system can achieve the high efficiency of constant temperature water cooling, and the shear free gate can reduce the labor intensity of workers.
According to the layout of the plastic parts, the mold is planned into three plates and the point gate is selected. The gate is set at the center of the top of the plastic parts. The point gate can significantly improve the shear rate of the melt, greatly reduce the melt viscosity, and is conducive to mold filling. Moreover, as a packaging container, the plastic parts have a high demand for appearance quality, and the residual traces of the point gate are small, which can ensure the surface quality of the plastic parts; During demoulding, the gate is actively pulled off, facilitating the automation of product production process, improving production power and increasing economic benefits.
Yes, we have successfully manufacture double color 5 gallon bottle cap mould and some two-color flip top cap moulds
Cap injection molding process enables each finished one to achieve high precision, uniformity in size, and shape, and high surface finishing. In this process, the plastic particles are heated in a metal hopper to the point that they become very soft and pliable. It is possible to add color to the plastic at this stage. The softened plastic is then injected under high pressure into a complex structural steel or aluminum mold. Here the glue is filled into the cavities in the mold and cooled enough to harden. Finally, the mold will open for bottle cap removal.
<p>While selecting a Bottle Cap Mould, it is crucial to choose a company with a proven track record in the production of quality caps. A bottle cap mould maker must also have access to effective materials and highly skilled technicians. QX Mould is a manufacturer of cap molds, It's your best choice.</p>
