FAQs: Medical Housings for Healthcare Applications

Medical housings are precision enclosures, protecting, and housings for the medical devices which are…. sutures, precision enclosures for medical devices, medical diagnostics, and other medical housings, sutures, precision enclosures for medical devices, and medical diagnostics, and other medical housings, sutures, and housing interventional, medical devices, precision enclosures for medical devices, and other medical housings.

Aluminum 6061-T6 is lightweight, easy to machine, strong enough, and corrosion resistant enough for housings for non-implantable devices. For reusable surgical instruments, medical grade stainless steel 316L has proven biocompatibility and corrosion resistance to sterilization chemicals and also has enough structural strength. Biocompatibility for devices that contact tissue and strength for non-implantable devices makes titanium exactly desirable. Strength, electrical insulation, design versatility for ergonomic handheld devices, and compatibility with autoclave sterilization for medical plastics like PEEK and Ultem add to the overall value.

Creating complex three-dimensional enclosures that integrate ergonomic contours and mounting features is also an enabler of multi-axis CNC milling. Precision boring machines control and seal the dimensions of interface and O-ring grooves. Closure threads and mounting interfaces are produced from thread milling. Internal cavity pocket milling and battery compartment pocket milling create electronically compartmented housings. Smooth biocompatible surfaces are created from surface milling. Engraving and laser marking provide model and serial number permanent identification and regulatory marking resistance to sterilizatio

For O-ring compression and hermetic sealing, we reach seal groove dimensions of ± 0.002 inches we achieve thread tolerances of ± 0.003 inches for secure closures, ± 0.005 inches on mounting hole positions for assembly alignment, ± 0.010 inches for overall housing dimensions, and surface flatness of 0.005 inches on mating surfaces we achieve reliable environmental protection and a precise fit of interlocking components.

Yes. We offer flexible manufacturing capabilities including:
Rapid prototyping for design validation
Low-volume production for specialized applications
High-volume production with consistent quality control
Full structural and dimensional verification at every stage

As-is components, all manufacturing takes place under ISO 13485 certified quality management systems specifically for medical devices, ensuring full compliance with FDA regulations for Class I, II, and III devices, European Medical Device Regulation (MDR) requirements, material biocompatibility per ISO 10993, traceability from raw material to final product, and adherence to Good Manufacturing Practices. This ensures patient safety and regulatory compliance.

We provide comprehensive finishing solutions tailored to aerospace requirements:
Anodizing (Type II and Type III)
Passivation for corrosion resistance
Precision polishing for aerodynamic surfaces
Custom protective coatings and thermal barriers

Standard medical housings are completed on a time frame of 10-15 business days. This duration encapsulates the steps for machined housing, surface treatment and quality verification. Complex medicolegal sealed enclosures in contrast are completed on a timeline of 3-4 weeks. Prototype runs for design verification and regulatory testing can be expedited within 7-10 days based on the availability of the material and the finishing requested.

Having a proper dimensioned seal groove allows for the O-ring to seal correctly allowing for a fully IP67 or hermetically sealed enclosure to block electronics from bodily fluids and moisture during sterilization. Right-dimensioned threads ensure closure prevents accidental opening during procedures. Surfaces that are biocompatible, smooth, and with a roughness average below 1.6 microns are easily cleaned and hinder bacterial colonization. The spacing of wall thicknesses and the described encased machinery drop protection to IEC 60601 mandated structural integrity. Assembly and layering guidance tolerances are aimed to reduce defects forming in manufacture. The ability to endure autoclave sterilization cycles: 500+ for reusable devices; and to maintain integrity of appearance, thickness, and dimension stability, along with quality of the material all encapsulates the requirement for repeated sterilization.
