With the rapid development of the new energy vehicle (NEV) market, charging infrastructure has become an essential part of the ecosystem. Its quality and reliability are increasingly valued by manufacturers and users alike. Leveraging deep expertise in Metal Injection Molding (MIM), MIMO Metal successfully developed a key metal component for the charging handle of a leading NEV brand. The part met high standards in function, strength, mass production, and appearance, earning strong recognition from the client.
The client, a well-known NEV manufacturer, was developing a high-end smart charging station. The handle featured an ergonomic design requiring internal metal parts with high strength, tight tolerances, an attractive finish, and strong corrosion resistance. Traditional machining methods posed challenges in cost, complexity, and efficiency. Thus, the client sought a more efficient and scalable solution.
At the start, MIMO Metal's engineering team engaged closely with the client's R&D team. Based on 2D and 3D designs, we quickly identified that the part was ideal for MIM. This technology is well-suited for producing complex small metal parts with high precision, reduced material waste, and shortened lead time.
Given the outdoor application and frequent handling, we recommended 316L stainless steel powder. It offers excellent corrosion resistance, mechanical strength, and supports advanced surface finishing.
In mold design, we optimized draft angles, gate placement, and shrinkage control to ensure dimensional accuracy within ±0.03mm, meeting the assembly precision required.
During debinding and sintering, we developed a dedicated thermal profile to control internal stress and enhance part strength and stability.
To meet the client’s high surface quality expectations, we provided multiple finishing options such as mirror polishing and electropolishing. Salt spray tests were conducted to validate long-term durability in real-world conditions.
From design review to mass production, the project was completed in just two months. The initial prototypes passed all client evaluations, and batch deliveries have since been made, with thousands of charging handles in use.
The client noted that MIMO’s MIM solution shortened development time, improved part consistency, and enhanced the product’s visual appeal—strengthening their brand image.
This project demonstrates the versatility of MIM technology in the NEV industry. MIMO Metal remains committed to delivering customized solutions by combining industry knowledge with advanced manufacturing techniques.
Looking ahead, we will continue investing in core technologies and expanding MIM applications in NEV and smart manufacturing sectors—creating greater value for our customers and supporting industrial transformation.
