Lamp shades, lamp cups, and lighting reflectors are closely related applications for metal spinning. They are usually round, hollow, and visible after finishing, which makes the forming process important for both shape and appearance.
Why lamp parts are often spun
Many lamp shades and reflectors have axisymmetric profiles: cones, domes, cups, shallow bowls, and stepped shapes. Metal spinning can form these shapes from sheet metal with efficient material use and a smooth continuous surface.
Define the part family first
A small decorative shade and a large industrial reflector should not be quoted the same way. Buyers should group parts by diameter, depth, material, thickness, edge style, and finish. This helps the supplier recommend the right machine class and tooling plan.
Reflector quality depends on repeatability
Lighting parts often need stable profiles across batches. If the diameter or curve changes too much, assembly and optical performance can suffer. CNC control helps keep roller paths repeatable once the tooling and program are proven.
Material and finish should guide machine selection
Aluminum is common for reflectors because it is light and formable. Stainless steel or mild steel may be used for heavier shades or industrial parts. The chosen finish – polishing, painting, anodizing, or plating – affects how carefully the surface must be protected during spinning.
Practical questions for lamp shade buyers
- What is the largest lamp shade or reflector diameter?
- Is the part shallow, deep, stepped, or cone-shaped?
- Which material and thickness will be used?
- Does the part need polishing, coating, or tight visual quality?
- Will the supplier provide tooling and sample run-off?
