Manufacturing
How we make this part
Process, material options and inspection for cnc lathe turned brass parts for medical devices.
Medical brass parts are turned on CNC lathes with careful control of burrs and surface finish, since particles or sharp edges can affect seals and safety. Threads for gas fittings are cut to standard forms and checked with gauges. Cross holes and flats are added with live tooling. Parts are cleaned after machining to remove oils and chips before plating or packaging.
Brass offers good machinability and corrosion resistance and is common for medical gas and fluid fittings. Nickel or chrome plating improves cleanability and appearance; lead-free brass grades are available when regulations require. Other options include polishing, grinding, sandblasting and heat treatment for selected materials. For implantable or patient-contact parts, stainless steel or titanium are typically specified instead.
Critical dimensions are measured on every part, threads are checked with gauges, and surface finish can be measured with roughness testers. Material certificates and inspection reports are available, supporting the buyer's traceability needs. Typical uses include medical gas outlets, flowmeter parts, regulator components, hospital bed adjusters, dental equipment fittings and instrument bushings.
FAQ
Frequently asked questions
Is brass acceptable for medical device parts?
Brass is widely used for non-implant medical equipment such as gas fittings, valves and connectors, often with nickel or chrome plating. It is not used for implants or long-term patient contact, where stainless steel or titanium are preferred. Check your device's regulatory requirements.
Can you provide traceability for medical parts?
We can provide material certificates and inspection reports for each batch, which support your device documentation. We operate under ISO 9001. If you need specific labeling or batch records, tell us at the quote stage so we can include them.
