A plastic bottle cap mold is the perfect solution for producing a variety of bottle closures for various applications, such as spraying, pumping, or misting. Typical uses for this type of plastic cap mold include the continuous thread Plastic bottle mould/mold for water bottles, lotion pumps, and trigger sprayers. For other applications, a more custom-fitted cap is possible with a combination of die plate cavities. For more information about these molds, please visit our website or contact us today.

The sprues are important features of a plastic cap mold because they determine the amount of individual cap cavities that can be produced with a given mold. However, if sprues are too long, the plastic will become too stiff to be molded successfully. Therefore, the number of caps made per cycle is limited. Ideally, sprues should be around a millimeter-wide to maximize production and reduce costs.

The sprues are crucial to the successful molding of a plastic cap. These sprues should be able to hold a large amount of plastic, ensuring a uniform thickness. Proper sprues allow the plastic to set quickly and evenly. Besides, sprues are less likely to etch into the surface of a mould if they are made of silicone. To avoid this problem, ensure that the mold is water-cooled.

The inside threads are an important part of the design of a cap. These threads can be a snap-on rib, a major undercut, or a major undercut. These cuts are often incorporated into technical products. Many plastic cap moulds feature inside threads. This type of cap can be made more easily and quickly if the ribs are not brushed in. Similarly, if the plastic does not stick to the mould, it will be easier to remove.

The most common plastic cap Molds have as many cavities as possible. These molds are very flexible, and can be designed with as many as eight cavities. The sprues are used to feed plastic into the mold. The sprues are formed in the stationary face of the cap mold. These sprues are used to carry the liner. They can be threaded after molding to make the caps more attractive.

The interior of a plastic cap Mold is important for the product. The threads are typically designed for easy removal and are usually made of a standard material. Some molds are adapted to use threaded inserts, which allow for a more efficient process. The sprues are critical components for the process of producing a cap. The sprues must be sized for the product to be manufactured.

Typically, the cap plastic is a honey-like substance that is too thick for practical use. To thin the plastic, simply mix 2 parts solvent with the cap plastic. The plastic will flow into the mould, but it must dry between layers. Conventional brushes deposit thicker plastic, which is more difficult to airbrush into deep recesses. Consequently, these tools will require a lot of dry time between layers. The same principle applies to the inner and outer parts of the mould.
