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.
