Urethane Molding

Urethane Molds

to Produce a Variety of High Quality
Custom Applications

Urethane casting and molded products can solve your need for a specific part. We have a variety of urethanes available and can cast parts using your molds, plans, or specifications as well as creating new molds to manufacture your parts.

Sioux Rubber & Urethane uses state-of-the-art processing equipment and advanced molding techniques to produce high quality urethane parts for all types of industries. Polyurethane, being liquid, can be poured into almost any shape of mold producing a variety of high quality and reliable custom applications.

If you are looking for a permanent bond Sioux Rubber & Urethane excels at this process. We can surface bond, encapsulate, and cover a large variety of substrates. If your part or piece is steel, stainless, aluminum, cast, galvanized or even wood or concrete we can permanently bond our urethane products giving you your desired outcome or product. For most of your urethane and metal assemblies, Sioux Rubber & Urethane can manufacture the metal inserts for you to provide a complete “one stop” source for your finished part.

Take their

word for it:

It is hard to beat from the aspect of economy, abrasion resistance, lining integrity, and high temperature resistance. [Sioux Rubber] has done an excellent job of installing and testing rubber liners that we have used in our scrubbers and reactors… delivery times are accurate… and the quality of the job is top notch.

Abrasion Values of Urethane

The following test results are from 50:50 sand and water slurry. The velocity of the slurry was 680 feet/minute for 7 hours. The numbers represent material loss, therefore the lower the number the better the abrasion resistance.

The materials tested are generic. The various brand name manufactured products may exhibit higher or lower values depending upon formulation and test methods conducted. The sole intent of the above is to provide the end user with a guide in the selection of abrasion resistant materials.
