The 5 Benefits of Metal Stamping for Medical Devices
Metal stamping is often used for the manufacture of medical instrument parts specifically if complex design specifications are required. Deep draw metal stamping allows for total accuracy, precision, and quality for medical needs with customized designs.
There are five key benefits of metal stamping for medical device components:
The metal stamping process is largely automated once the tooling is set into the transfer press. During the deep draw process, outside secondary operations can be completed within the press reducing the overall cost of the part. In most cases there is an initial one-time engineering and tooling fee for the life of the part and a lower cost per part compared to traditional machining methods.
Precision is most important when it comes to the manufacture of medical device components. Deep draw metal stamping runs in a highly automated manner and in doing so generates extremely precise parts, completed with a high level of accuracy. This allows for exact specifications to be met in high volumes.
The deep draw process allows for high volume production runs capable of producing thousands of parts an hour.
Perhaps the biggest benefit of deep draw metal stamping is its versatility. Lightweight and durable metal can be transformed into small, often complex shapes while still maintaining tight tolerance requirements.
We deliver complex parts to the medical device industry which requires a reliable quality control system as well as thorough documentation and traceability. We use quality assurance methods such as PPAP, APQP, FMEA, visual inspection, optical measurements, and process control. We also conduct medical validation including IQ and PQ to ensure safety, effectiveness, and compliance.
Materials often used in Medical Hardware Parts
Aluminum, Titanium and Stainless Steel are commonly used in metal stamped medical devices primarily due to the following material properties:
- Easy sterilization
- Corrosion and wear resistance
- Retaining shape
- Stable shelf life

We offer an array of value added solutions to deliver your completed part including:
is a process used to deburr, descale, burnish, clean and brighten small parts. Specifically paired with pellets of media combined with the batch of parts are placed into a tub of a vibratory tumbler. The tub of parts mixed with the media then vibrates which causes the media to rub against the parts until a desired surface finish is achieved.
uses high frequency, high intensity sound waves transmitted through a liquid to scrub the surface clean of submersed parts. Contaminants such as dust, dirt, fibers, grease, oil and other microscopic impurities are removed to achieve a high level of cleanliness.
improves the corrosion resistance properties of stainless steels. A solution of nitric or citric acid is used to dissolve iron and other contaminants embedded in the surface during the metal forming process that can cause corrosion.
is an electrochemical and reverse plating process that removes the outer layer on a metal part to address microscopic imperfections within its finish. The electropolishing process serves to polish, passivate, and deburr metal parts.
the process of applying a thin metal coating to the surface of a part to create a more durable and defect free surface. This method is often used to apply hypoallergenic coatings to medical devices to create a safe and sanitary surface.
