Automotive knob two-color injection mold is a mold type for the production of automotive knobs, with the following characteristics and advantages:

Two-color injection molding process: This mold can use two different colors or materials of plastic in the same production process, through two injection molding, so that the knob forms a combination of two colors or materials. For example, the main part of the knob is injected first, and then the decorative part of the surface or the specific function part is injected, so as to achieve a diversified combination of colors and materials, and improve the beauty and functionality of the product. For example, the outer ring and inner ring of some car knobs use different colors, or the operating part and the indicating part of the knob use different materials.

High-precision molding: In order to meet the high-precision requirements of automotive parts, automotive knob two-color injection molds pay attention to precision control in the design and manufacturing process. The cavity structure of the mold has been carefully designed and processed to ensure the dimensional accuracy, shape accuracy and surface quality of the knob. High precision molding can ensure the assembly accuracy of the knob and other parts of the car interior, so that the operation of the knob feels good, but also improve the overall quality of the car interior.

Complex structure design: Automotive knobs may have a variety of complex shapes and structures, such as non-slip lines, indicating marks, internal clasps, etc. The two-color injection mold needs to be able to adapt to the molding needs of these complex structures, and the complete injection molding of the complex shape of the knob is realized through the clever mold structure design, such as the slider, the core pulling mechanism, etc. For example, for knobs with side faces or grooves, the slider in the mold can be moved during injection molding to form these features.

High stability and durability: In the automotive production process, the mold needs to withstand a long time of high intensity use. Automotive knob two-color injection molds are usually made of high-quality die steel materials, and after appropriate heat treatment and surface treatment processes to improve the hardness, strength and wear resistance of the mold, to ensure stable performance and long service life in frequent injection cycles, and to reduce the maintenance cost and replacement frequency of the mold.

Efficient production: In order to adapt to the large-scale production needs of the automotive industry, this mold is usually designed to have a high production efficiency. For example, the multi-cavity mold structure can produce multiple knobs at the same time to improve production output; Optimize injection molding process and cooling system, shorten injection molding cycle and improve production efficiency.

Quality control: As an important part of the interior of the car, the quality of the car knob is directly related to the experience and safety of the car. The two-color injection mold is equipped with strict quality inspection and control means in the production process, such as the sensor installed on the mold to monitor the injection molding parameters in real time, sampling testing during the production process, etc., to ensure that each knob meets the quality standards.
