Describe the component
Metal spinning is typically used for rotational shapes. Supply a section drawing with outside and inside profiles, overall diameter, depth, flange geometry and any holes or downstream machining. Mark the drawing revision and measurement units.
Choose material and define finish
Identify the alloy and grade, starting thickness and surface finish. Explain corrosion exposure, appearance requirements and any polishing, coating or secondary processing. Material changes can affect manufacturability and need approval.
Separate critical dimensions
Mark mating dimensions and functional tolerances separately from cosmetic features. Agree how thickness, edge condition, runout and surface appearance will be measured, and identify the inspection points relevant to the part.
Plan tooling and volumes
Provide prototype quantity, expected batch size and annual demand. Ask who owns tooling, what the tooling charge includes and how drawing changes are handled. Lead time, price and process selection depend on the approved geometry and order.
