Prototype CNC Machined Brass and Titanium Appliance Knobs
These are prototype control knobs, dials and selector rings for premium appliances, CNC machined in brass, titanium, aluminum or steel. They let design teams test feel, weight, finish and fit before committing to casting or mass machining. The service suits appliance and consumer product designers who need a few high-quality samples for user testing, photography or design approval.

Manufacturing
How we make this part
Process, material options and inspection for prototype cnc machined brass and titanium appliance knobs.
Prototype knobs are turned and milled from bar on CNC lathes with live tooling, including grip patterns, indicator grooves and internal bores. Detent features, if part of the knob, are machined in the same setup. Several material and finish variants can be made from one program, so design teams can compare them side by side quickly.
Brass knobs feel heavy and premium and can be plated in chrome, nickel or PVD colors. Titanium Grade 2 or 5 is light, strong and has a distinctive gray tone, but machines slowly and costs more. Aluminum is the most economical and anodizes in many colors. Steel knobs can be brushed or black oxided. Weight and thermal feel differ noticeably between materials.
Prototype knobs are inspected for bore fit, concentricity and cosmetic finish before shipping, and design changes can be turned around quickly. Typical uses include range and oven knobs, coffee machine dials, audio volume knobs for appliances, smart home control rings and selector dials for premium kitchen and bathroom products, plus samples for trade shows and marketing photography.
FAQ
Frequently asked questions
How many prototype knobs can you make?
From a single piece upward. Designers often order sets of several material and finish variants so they can compare feel and appearance. Prototype knobs usually ship in about 3–7 working days depending on the finish; PVD and plating may add time.
Is titanium worth it for appliance knobs?
Titanium offers a premium look, low weight and excellent corrosion resistance, and it stays cool to the touch compared with aluminum. However, it is expensive and slower to machine, so it suits high-end products or limited editions. Brass with PVD can achieve a similar premium feel at lower cost.
