Customized Powder Injection Molding Parts For Mobile Phone Card Tray

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.

Quality Assurance:

ISO 9001-certified process control.

Full PPAP documentation (FAI, CPK, PFMEA).

CTQ dimensions verified via automated optical inspection (AOI).

Salt spray testing (48+ hours), adhesion tests, and mechanical validation.
