Custom made colored solid rubber foam balls

Rubber foam balls can be custom made in different dimensions and colors for a defined product or assembly. The intended construction needs to be established alongside the visible shape. A cellular foam ball and a solid elastomer ball can behave differently, so color and diameter alone do not describe the component.

Define how the ball will be held, compressed, or contacted in the finished design. The selected material and internal structure should suit that role, including the expected environment. The outer size also needs to leave the required clearance if the ball fits within another part.

Check the finished component in the actual arrangement rather than judging its behavior only by squeezing it by hand. Avoid assuming a particular bounce, load capacity, or softness from the word rubber. If the ball is incorporated into a toy or another user-facing product, the complete product must meet the requirements of its intended use. Keep the surface clean with a method suited to the selected material and replace a damaged ball if tearing or deformation changes its fit.

Material options

Custom rubber balls in a specified cellular or solid construction; coordinate diameter and color with the finished design.

Hardness selection

Foam references of 20–30 Shore C and 35–45 Shore C distinguish a softer squeeze from a more supported feel. Solid rubber options: 30–90 Shore A. Assess the selected ball in its receiving part.

Custom dimensions

Set the outside diameter against the space that holds or contacts the ball; identify whether it is squeezed or merely located.

Fit & assembly

Confirm the internal construction before comparing fit. Equal outside diameters do not establish equal deformation under contact.

Use & inspection

Use a cleaning method suited to the compound and replace a torn or distorted ball when its fitted position changes.

Photos illustrate structure or material only. A foam ball needs outside clearance appropriate to how the receiving part holds or compresses it. ETOL directly manufactures custom-shaped silicone and rubber parts to your requirements.
