Urethane casting has several advantages over other plastic manufacturing processes like injection molding and additive manufacturing (3D printing). It is fast, inexpensive, and produces high-quality parts.

Over the last two weeks we’ve covered the advantages of speed and cost. This week we’ll take a look at the third advantage: quality.

The cast urethane process can use a variety of formulations to produce parts that are soft or hard, colored or transparent. The silicone molds provide excellent surface finish detail and can accurately mimic production textures.

In addition, parts can be over-molded, have inserts incorporated into them, and have post-process treatments like painting.

Urethane casting produces parts with physical properties on par with injection molding, and the parts are structurally superior to their 3D printed counterparts. 3D printing – despite continuous improvements – still has material and structural integrity limitations. Urethane casting, in contrast, produces high-quality, robust parts.
