Crumb Rubber Products
A good use for old tires is to grind them up & re-use the rubber bits to make new products. This ground up rubber is known as crumb rubber, a few uses worth mentioning is soft covering on playgrounds, road base filler, and molded products.

The products shown here were created for a trafic safety company in southern California. I designed the product, then designed & built the molds that produce those products, and helped with engineering assistance to get the new mold line up & running efficiently.

From 5 different mold designs, some with interchangable features, the company is able to create 17 different parts.
