This is general product-selection guidance, not engineering advice. Confirm the final product and specification for the application.
Provide a drawing or sample
A dimensioned section drawing, 3D file or physical sample helps define the geometry.
State the function
Explain whether the part seals, cushions, isolates vibration, protects an edge or carries wear.
Describe the environment
Include temperature, fluids, outdoor exposure, movement and expected load.
Confirm quantities and timing
Prototype and production quantities influence the most suitable manufacturing approach.
