Designing a Flip Top Cap Mould

Unscrewing threads

When creating a plastic flip top cap, you have a couple of options when it comes to unthreading the closure threads. First, you can opt for an unscrewing thread, which is more challenging but will not break the integrity of the thread. Second, you can opt for a jump thread, which will be easier to remove from the mould, but will not offer the same benefits. This type of mould requires special machines and a slow molding cycle.

This type of mould uses a hydraulic cylinder to rotate the core while the parts are being molded. The material must be weighed enough to be able to float up the mold while the screw retracts to fill it with the next shot. You can also choose a mould design with different construction to meet the needs of customers. However, make sure you carefully check the features of the mould before making a purchase.

Core

The core of a Flip Top Cap mould has a number of details. These include the design of the inserts, the cap material, and customer requirements. Depending on the design, the steel used for the detail steel can be HRC48 or HRC52. If a cap is made from plastic, the steel should be at least HRC42. However, the more complicated the cap mould is, the harder it is to strip the cap.

Cavity with inserts

The cavity with inserts for flip top cap mould has a two-time ejection structure. During the process, the core and stripper plate are pushed out twice and continue to push out for 14mm. The final part of the process is the drop of the cap. The cavity with inserts is highly customizable and is available in various designs and shapes.

The mould's steel composition depends on the product type and the cap material. In general, 1.2316 steel is used for the cavity and insert core. P20 steel is used for the A/B plate, while C45 steel is used for the base. Customers can also specify the type and hardness of the steel to be used. To ensure the lifetime of the mould, it should be made of high-quality steel.

Steel used

Depending on the design of the cap, the steel used in the flip top cap mould can either be HRC48 or HRC52, depending on the application. The steel used in the moulds can be hardened to the desired hardness and polish ability, depending on the customer's needs. The steel used in the moulds should be chosen with care to avoid damage to the product during the production process. The steel used in flip top cap moulds must be hard enough to withstand the required production volumes.

The main steel used in the closure mould is tempered HRC 45-52. Precision tooling and high speed processing are other features of a flip top cap mould. It will also be manufactured with standard tooling that enables easy maintenance. The auto-closing system of the mould will enable the user to easily install and disassemble the molds. These features will ensure that the finished product is safe and reliable.

Lead time

Creating a plastic mould for a flip top cap is a complex process, and lead time for a flip top cap mould can range from two to seven weeks. The lead time depends on the complexity of the design, the materials used, and the complexity of the mould itself. It is usually a good idea to pay for the mould material in advance so that you know what you are getting, and you can test it before putting it to use.

With the right combination of features, a plastic cap mould can yield a high-quality product in a relatively short amount of time. The cycle time of a cube mould is significantly shorter than that of an unscrewing mold, so there is a higher chance of a high-quality product. Another advantage of cube molds is their efficiency, as they can produce as many as 13,000 parts per hour, depending on the mould.

Quality

The quality of a Flip Top Cap Mould is of utmost importance. Its durability, shinniness and polishing ability are vital for the quality of this packaging material. Its material is usually S136 steel for the core and cavity. P20 and C45 steel are used for the A/B plate and mould base. According to the requirements of the customer, the steel used for the mould can also be custom-made.

A flip top cap mould is generally used for detergent, shampoo and cosmetic bottles. Its main purpose is to ensure the quality of the closure. It should not leak any water. Another important feature of the mould is its connection with the base. An experienced manufacturer should understand this aspect and should have sufficient experience in designing and constructing molds for this type of bottle. In the end, a good flip top cap mould will help to ensure that the product meets the needs of the customer.
