A car manufacturer aims to optimize the design and manufacturing process of its automotive rearview mirrors to improve product performance and reduce costs. They decide to employ overmolding injection molding technology to integrate the mirror housing and sealing component, replacing traditional assembly methods.

Solution: Through overmolding injection molding technology, the mirror housing and sealing component of the automotive rearview mirror can be simultaneously formed in a single injection molding process. The housing part is injection molded using high-strength and weather-resistant engineering plastic, while the sealing component is molded using flexible and chemically resistant rubber material. During the injection molding process, ensuring a strong bond between the two materials is crucial to ensure product sealing and durability.

Results and Advantages:

1. Cost reduction: By adopting overmolding injection molding, the need for traditional assembly processes is eliminated, reducing production time and labor costs.

2. Improved product quality: Precise control over the injection molding process ensures dimensional accuracy and consistency of the mirror housing and sealing component, enhancing product quality and reliability.

3. Enhanced design flexibility: Overmolding injection molding technology allows designers to achieve more complex shapes and structural designs, catering to different vehicle models' requirements.

4. Reinforced product performance: By selecting suitable materials for the housing and sealing component, the rearview mirror's impact resistance, weather resistance, and chemical resistance can be improved.

This case study demonstrates the application of overmolding injection molding technology in the automotive industry. Through design and manufacturing process optimization, it achieved cost reduction and enhanced product performance. Similar optimization strategies can be applied to other product sectors, providing businesses with increased competitiveness and market share.
