6-24 cavity Cap injection molds are suitable for mass production, effectively improving production efficiency and reducing costs.
In the multi-cavity mould of the cap, there are usually 6, 8, 12, 24 and so on cavities.
The rectangular pattern facilitates convenient arrangement.
Thus simplifying design and manufacturing, and ensuring each cavity receives uniform clamping force.
Special 6-24 Cavity Cap Injection Molds components
The mold system has several critical components that ensure durablity and precision.
The main mold base uses P20 steel with nitroaen tregtment.
The core and cavity components are made from stavax steel with vacuum quench treatment.
Pin-valve gate systems with pneumatic drive that provide precise control.
Independent cooling systems for core, cavity, and valve gate components.
Advanced self-locking structures with interchangeable components.
Different types of 6-24 cavity Cap Injection molds
Moulding caps come in various types, each designed for specific applications.
In order to select the most suitable one for a particular injection moulding project, it is helpful to understand the different types.
The standard cap is widely used in general injection moulding applications.
It offers a good balance of performance, cost-effectiveness, and versatility.
Standard caps are available in different sizes and configurations to accommodate various mould designs and material requirements.
The hot runner cap is used for high-volume production and complex part designs.
Hot runner caps feature a heating system that keeps the material in a molten state as it enters the mould cavity.
This eliminates the need for re-heating the material with each injection cycle, resulting in faster production cycles and reduced material waste.
The multi-cavity cap is often used for projects that require multiple cavities.
Allowing for the simultaneous injection of multiple parts within a single mould.
It improves productivity and efficiency by producing multiple components in each injection cycle.

Mold material selection
Choosing the right mold material is crucial.
Commonly used materials include alloy steel, carbon steel, and hardened steel, among others.
Matching the number of cavities to the machine
When selecting the cavity for the injection molding mold, the melt capacity, mold size capacity.
And clamping pressure of the machine must be considered.
The number of cavities must match the machine’s capacity to ensure production efficiency and product quality.
Cooling system
Reasonable cooling system design is the key to ensuring that the mold molding cycle is shortened.
For example, some molds use spiral water cooling to enhance the cooling effect, which speeds up the molding process.
In addition, designers should design the cooling system of the mold with uniform cooling of the cavity in mind to avoid defects in the cap.
Gating system
The design of the gating system directly affects the mold-filling effect of the melt and the quality of the product.
For example, some molds are designed with a pointed gate.
Which can significantly increase the shear rate of the melt and reduce the viscosity of the melt, which is beneficial for mold filling.
In addition, the use of a hot runner system allows for faster cycle times for multi-cavity moulds.
