Core Viewpoint - Metal Injection Molding (MIM) technology is emerging as a viable development direction for humanoid robots, with its applications in consumer electronics and automotive industries maturing, leading to increased demand for high-precision and complex components in advanced manufacturing sectors [1][4]. Group 1: MIM Technology Overview - MIM is a new near-net-shape forming technology that combines modern plastic injection molding with powder metallurgy, allowing for the production of complex metal parts with high precision and excellent surface quality [3][4]. - The MIM process involves mixing solid powder with an organic binder, shaping it through injection molding, and then removing the binder followed by sintering to achieve the final product [3][4]. Group 2: Applications in Robotics - MIM's ability to create complex integrated structures in a single molding process is a key advantage, enabling the production of intricate designs that traditional machining cannot achieve [4][6]. - The technology is suitable for manufacturing critical components in humanoid robots, such as joints and sensors, balancing material performance and lightweight design [6][11]. Group 3: Advantages of MIM - MIM can adapt to a variety of high-strength materials, including iron-based alloys and titanium alloys, meeting diverse performance requirements for different parts [6][11]. - The process allows for the production of small, precise components with tight tolerances, making it ideal for applications in robotics where lightweight and compact designs are essential [7][11]. Group 4: Challenges and Limitations - Despite its advantages, MIM is still a new technology with high mold development costs, making it less suitable for low-volume production typical in the early stages of humanoid robot development [8][12]. - The lengthy processes of debinding and sintering can hinder the economic viability of MIM for small batch production, which is often required in rapid prototyping and iterative design phases [8][12]. Group 5: Market Potential - The global MIM industry is valued at approximately 25 billion, with China accounting for over 55%, projected to reach 57.49 billion by 2030, with a CAGR of 10.7% from 2024 to 2030 [12].
