About Us

Since our inception in 1944, Perma-Flex® has kept one fundamental principle in mind: helping each customer, one at a time, select the appropriate products to make quality rubber molds and castings.

What Makes Us Special

For 48 years, Perma-Flex® operated a mold making shop specializing in custom rubber molds. However, there was a need for better material solutions. Perma-Flex® recognized this need and expanded it's role to specialize in material development and improvements. Today, Perma-Flex® is a key material supplier in North America and around the world.

Our knowledgeable and friendly staff is available to assist with your mold making needs. We pride ourselves in building close working relationships and getting to know our customers on a first name basis. This allows us to provide a level of service that is like no other. As part of your team, we work together to get the job done right.

For customers, the key to success is education. Our goal in education is to facilitate your good buying decisions. Perma-Flex® offers over 300 products. Choosing products that apply to your application can be time consuming and even costly. That is when our expert sales and technical staff can educate and assist you with the best choices or suggest possible alternatives. We will evaluate your requirements in detail before making recommendations. Then, we will explain the reasoning behind the choice. When you understand why, then you will be able to select the appropriate products for their best use and application.

Our Specialty - We Teach What We Sell!

No application is too small or too big, not when it is your application. We offer free technical service to assist you in product selection, techniques and procedures. Please contact us or visit our plant. At our plant, we work one on one with you to refine the application. Nothing is more important to us than your application.
