Double Injection mold base, or Two-color mold base, or Bi-color mold base. In the dual color injection molding process, this type of mold is designed to sequentially or simultaneously inject two different colored plastic materials into a single mold, thereby producing plastic products with dual or multi-color appearances.





Characteristic

1. Multi cavity design: usually with two or more injection cavities for simultaneous or continuous injection of plastic of different colors or materials. Usually composed of multiple layers of structure. Each layer has different materials or colors, and through the combination of mold bases and injection molding process, the multi color or multi material effect of the product can be achieved. The multi-layer structure enables the dual color non-standard mold base to have a wider range of applications, which can meet the color and material requirements of different products.



2. Complex structure: Due to the need to handle injection molding and bonding of two materials, the structure of the mold base is relatively complex, including rotating mechanisms, sliders, ejection systems, etc. Some parts of the double injection non-standard mold base may have adjustable structures. By adjusting the position or parameters of these parts, fine-tuning of product size, shape, and color can be achieved. The adjustable structure increases the flexibility and adaptability of the mold base, which can meet the personalized needs of different customers.



3. High precision requirements: In order to ensure the appearance quality and dimensional accuracy of dual color products, the manufacturing and installation of the mold base need to meet high precision standards. The double injection non-standard mold base emphasizes precision fit in structural design. The various components of the mold base need to be precisely matched to ensure the stability and accuracy of the mold during use. Precision fitting can reduce friction and wear of the mold during use, improve the service life and manufacturing accuracy of the mold.





Application of mould base

1. Consumer goods: such as phone cases, electronic product accessories, toys, etc., which usually require attractive appearance and feel.



2. Automotive components: Automotive interiors, buttons, switches, etc., two-color injection molding can provide better visual effects and tactile experience.



3. Medical devices: Some medical devices and components also use two-color injection molding technology to improve product recognition and usage safety.





Points for attention

When designing and manufacturing a "Double Injection mold base", special attention should be paid to the following points:



1. Material selection: The two injection molding materials need to have good compatibility and bonding to ensure smooth flow during the injection molding process and the final quality of the product. And it is usually made of high-strength materials to ensure the stability and durability of the mold during use. High strength materials can withstand greater pressure and stress, while also possessing good wear and corrosion resistance. This makes the two-color non-standard mold base suitable for various complex production environments and process requirements



2. Temperature control: During the double color injection molding process, it is necessary to accurately control the temperature of the mold and injection molding machine to ensure the injection quality of different materials.



3. Mold maintenance: Due to its complex structure, the maintenance and upkeep of molds need to be more meticulous and frequent to ensure their long-term performance and stability.



In summary, the "Double Injection Mold Base" is a key component in the double injection molding process, and its design and manufacturing have a significant impact on the final quality and appearance of the product. In practical applications, it is necessary to choose the appropriate mold structure and injection molding process based on specific product requirements and production conditions.

Ordering mold bases separately and considering them separately can bring multiple benefits, mainly reflected in the following aspects:



Cost effectiveness

1. Cost control: Ordering mold bases separately allows manufacturers to select the most suitable mold base materials and specifications based on specific needs, thereby optimizing costs. For example, for specific types of molds, the highest strength mold base may not be required, so lower cost materials or designs can be chosen.

2. Avoid over-investment: In some cases, molds may need to be replaced or adjusted frequently, while mold bases may be relatively stable. Ordering the mold base separately can avoid replacing the entire mold base at the same time during mold replacement, thereby saving costs.



Flexibility and customizability

1. Enhance flexibility: Ordering mold bases separately can provide higher flexibility, and manufacturers can quickly replace or adjust mold bases according to different mold needs to adapt to different production scenarios and product requirements.

2. Strong customizability: The mold base can be customized according to the specific structure and size of the mold, ensuring a perfect match between the mold and the mold base, improving production efficiency and product quality.



Improve production efficiency

1. Simplify mold design: Using standard mold bases can simplify the mold design process, reduce design time and costs. Because the standard mold base has been validated and optimized, it can ensure compatibility with various molds.

2. Shorten manufacturing cycle: Ordering mold bases separately can accelerate the mold manufacturing process. As the mold base is pre manufactured, manufacturers can assemble and debug the mold faster, thereby shortening the production cycle.



Ensure product quality

1. Improve mold stability: The mold base provides stable support and positioning for the mold, ensuring its stability and accuracy during the processing. Ordering the mold base separately can ensure that the quality and performance of the mold base meet high standard requirements, thereby improving the stability and service life of the mold.

2. Easy to repair and replace: When the mold malfunctions or needs maintenance, a separately ordered mold base can be easily replaced or repaired, reducing interference and impact on the production process.



Other advantages

1. Space saving: Some mold bases are designed to be compact and stackable for storage, and ordering mold bases separately can help make more efficient use of storage space.

2. Environmental protection and energy conservation: By optimizing the design of the mold base and material selection, the goals of energy conservation, emission reduction, and environmental impact reduction can be achieved.

In summary, separately ordering mold bases and molds has significant cost-effectiveness, flexibility and customizability, improved production efficiency, guaranteed product quality, and other advantages. These advantages help manufacturers improve their competitiveness and meet constantly changing market demands.
