Metal Fabrication
Hart specializes in tight-tolerance fabrication of custom medical device components using stainless steel and other biocompatible metals. Our engineers shape, join, and refine precision parts that require strong, corrosion-resistant, and clinically reliable performance. From fine needle geometries to welded assemblies and tube modifications, Hart delivers controlled processes that support both prototype development and scalable manufacturing for OEM medical devices.
Engineering-Driven Metal Fabrication for Medical Devices
Hart fabricates metal components with a focus on how each feature impacts clinical use, sterilization, assembly, and long-term stability. By engineering the manufacturing process around performance-critical requirements, we help ensure reliable function from prototype through high-volume production.
Tight-Tolerance Metal Features Built for Reliability
We form, grind, machine, and cut metal parts with exacting control over size, geometry, and surface finish. Precision tooling, process control, and 100% inspection where needed help ensure consistency across complex shapes, small diameters, and specialty features.
Prototype-Friendly Fabrication With No Minimum Orders
Whether you need early-stage sample parts or mature production, Hart supports flexible quantities with production-level precision. Our no-minimum approach helps accelerate testing, reduce risk, and streamline validation without committing to large orders prematurely.
Need intricate bends, flares, or custom geometries? Hart specializes in the details others avoid.
Medical device components often require small, precise metal modifications that demand advanced forming and specialized tooling. Hart engineers evaluate structural requirements, material response, and clinical use conditions to deliver solutions that hold tight tolerances without sacrificing manufacturability. With decades of experience in fabricating specialty medical components, we build features that support bonding, sharpness, flexibility, assembly, and long-term durability.

Our Core Custom Capabilities
Hart’s fabrication technology shapes, cuts, joins, and forms metal components with repeatable accuracy. With in-house tooling, grinding, cleaning, coating, and assembly, we maintain process control from raw tube to finished device.
Precision Forming: Bends, Flares, and Complex Geometries
We produce fine bends, flares, and tapers that meet exact dimensional and functional specifications. By controlling metal deformation and stress, we ensure structural integrity and smooth transitions for assembly and clinical performance.
Slots, Holes, Closed Ends & Tip Forming
Hart fabricates ultra-small features—such as side holes, vented tips, swaged ends, and plugged tubes—using controlled forming and cutting techniques. These features support fluid flow, guidewire passage, anchoring, and clinical navigation while maintaining structural stability.
Welded, Swaged, and Joined Components
We join dissimilar metals, attach hubs, reinforce assemblies, and create multi-part components using advanced swaging, welding, and bonding methods. Our joining techniques maintain interior lumen consistency, prevent weak points, and preserve performance through sterilization and use.
