The MIM precision frame is a high-performance metal component manufactured using advanced Metal Injection Molding (MIM) technology, specifically designed for medical device assembly and other high-precision applications. Combining the design flexibility of plastic injection molding with the structural strength of dense metal, this metal injection molding frame solves the limitations of traditional machining processes, enabling the production of complex, miniaturized parts with tight tolerances at scale. As a trusted supplier of medical device MIM components, we deliver parts that meet the strictest quality and biocompatibility standards, ensuring reliable performance in critical healthcare applications.
Our high precision MIM part achieves dimensional tolerances as tight as ±0.01 mm for critical features, with overall shrinkage controlled to less than 0.5% during sintering. This exceptional precision ensures perfect fit and alignment in modular medical device assemblies, eliminating the need for costly secondary machining in most cases.
We offer a range of biocompatible materials suitable for medical applications, including 316L stainless steel (corrosion-resistant and widely used in surgical instruments), 17-4 PH stainless steel (high strength for load-bearing components), and titanium alloy (lightweight and excellent biocompatibility for implantable devices). All materials are certified to meet ISO 10993 and FDA biocompatibility standards.
MIM technology allows for the production of complex geometry metal frames with intricate interlocking features, mounting holes, and open-center designs that would be impossible or prohibitively expensive to manufacture using traditional machining. This integrated design reduces the number of assembly parts, simplifies production processes, and improves overall product reliability.
The sintering process densifies the metal powder to more than 97% of theoretical density, resulting in mechanical properties equivalent to wrought metal. This allows us to design lightweight frames without compromising strength, a critical advantage for portable medical devices and wearable technology.
Our automated production process ensures consistent quality across large production runs. Every part undergoes strict dimensional and material testing, eliminating variations that are common in manual machining operations.
We offer a full range of post-processing services to meet specific application requirements, including precision machining for ultra-critical features, passivation for enhanced corrosion resistance, anodizing, and black oxide finishing.
