Medical assemblies often require tight clearances for optics, sensors, and snap-fit interfaces. We deliver die-cast parts with controlled wall thickness, stable bosses and mounting faces, and CNC-finished critical interfaces so components assemble consistently with predictable tolerances.

Our production flow incorporates particle control practices, dedicated cleaning and handling procedures for medical batches, and ESD-safe workstations where required. Parts destined for sensitive medical assemblies are handled, packaged, and shipped to minimize particulate and oily residues, and we follow customer-specified cleaning or passivation protocols.

We offer surface treatments and post-processing compatible with medical use — for example anodizing, conversion coatings, and medical-grade painting or plating as specified by the device manufacturer. Coating adhesion, thickness, and corrosion resistance are verified through standard test methods to ensure long-term appearance and function in clinical environments. Where sterilization is required, materials and finishing processes are selected and validated to tolerate the customer’s sterilization method (e.g., chemical sterilants, dry heat, or other processes) per their specifications.

We maintain material certificates, batch traceability, dimensional inspection reports (CMM), and process records that assist customers in regulatory submissions or supplier audits. GuangWei supports common quality deliverables — FAI reports, process capability data, and inspection lots — and can adapt documentation packages to customer or regulatory needs.

We collaborate with OEM design and quality teams early to reduce risks: specifying fillets and radii to reduce stress risers, locating bosses for reliable screw retention, and designing part features for repeatable casting and machining. This reduces field failures and simplifies qualification.
