Precision MIM Card Trays for Mobile Devices: Engineered Excellence
MFGsourcing delivers high-performance custom metal injection molded (MIM) SIM/memory card trays tailored for seamless integration in mobile devices. We support your full product lifecycle – from EVT prototyping and DVT validation to PVT mass production – ensuring precision, reliability, and scalability.
Manufacturing Process:
-
Feedstock Preparation: Fine metal powders (e.g., 17-4PH stainless steel) compounded with binders.
-
Molding: Automated injection molding into complex net-shape tooling.
-
Debinding: Catalytic or solvent removal of primary binders.
-
Sintering: High-temperature furnace densification (±0.3% dimensional control).
-
Post-Processing: CNC machining critical features, precision deburring, vibratory polishing, and surface enhancements (e.g., Ni plating, passivation, laser etching).
Cost Efficiency:
-
Tooling optimization for high-volume economies.
-
Material utilization >95%, minimizing waste.
-
Value-engineered designs reduce secondary operations.
