Geometry and load

State spring type, available dimensions, and installation constraints. For compression or extension, provide at least two force and length or travel points; for torsion, torque or force with arm and angle. Attach a drawing, sketch, or sample if available.

Use and acceptance

Add material requirements or environment, temperatures, corrosion, load type, cycles or target life, functional tolerances, quantity, and requested timing. Clarify inspection and assembly-packaging needs; feasibility requires technical review.
