One of the more commonly asked questions we get is about urethane durometer. Durometer is the measure of resistance to surface penetration. This is measured with an actual durometer hardness tester that pushes against the urethane and is represented in the shore A, D scales. A being the softer side of things and D being on the harder side.

The measurement of urethane durometer is the same regardless of manufacturer but the way urethane is manufactured can vary greatly. Acrotech Inc. which has been producing K•Prene® Urethane for the last 30 plus years has been at the forefront of custom molded urethane and urethane based products. Our history and success has consistently produced durable yet resilient urethane while maintaining exceptional value. We are certain that over time by correctly using K•Prene® you will see significant cost savings and value.

For those that do not deal with urethane on a daily basis and or are looking to potentially produce parts with urethane please use the following chart. This chart is used as a guideline only comparing everyday items to the shore A / D durometers of our standard K•Prene® products.

Of course there will be questions. We are here to answer them. In certain cases and applications you may benefit from a different durometer than what you are currently using. We can discuss this more in detail if you contact us. If you are just starting and would like to look over our catalog please visit this page to request your own along with a sample keychain. If you have a CAD file or would like to upload a sketch of a product that you’d like to make in urethane please visit this page for more information on how to do that.

Acrotech Inc. offers several different sized sheet metal roll bending machines to cover a vast array of applications and product lines from thin intricate sheet metal to thicker heavy duty sheet metal. Our unique roll bending machine lineup offers those looking to take advantage of the popular one pass two roll machine while using urethane to help reduce makings on the finished product. With our machines we are able to roll parts the size of your finger to as big as you are tall. This is achieved by using different attachments that are sold separately from our base units.

In particular one of our most popular roll bending units is the 1618. This machine is quite versatile and able to roll smaller to medium sized sheet metal parts up to 18″ of working roller length in 16ga in mild steel. With a powerful 1hp motor this machine can be set up for some fast repeatable runs. We offer a small OD attachment that will allow you to roll parts as small as 1″ in diameter for precision parts repeatable for production use. Contact us to see how we can help you get on a roll in 2020! 

We have scanned and uploaded a clean / easy to read version of our old Metalforming Guidebook. In this guidebook you will find several ways we suggest forming metal using urethane. There are a lot of older techniques being used but some still apply today and are invaluable when fabricating with urethane for the first time. The guidebook goes through topics such as, urethane properties, urethane for drawing metal, embossing, forming, stripping, shedding and more.

Check out our newest YouTube video. Embossing Sheet Metal with Urethane. Urethane is a perfect universal die pad for embossing. It will handle all types of material and details. We stock our standard sheets in 40A, 60A, 80A, 90A, 95A and 75D We will custom cut these to your needed size and ship daily. Because of so many variables you may need to experiment on the durometer harness to achieve your desired results. If you are unsure feel free to contact us anytime. Contact Us Here.

Urethane is that likely choice for embossing sheet metal materials that most haven’t even heard of or thought of using. The urethane’s elasticity is such that it will form and create the other side of the die when forming parts. As pressure increases the urethane will try to fill the voids in your negative creating a nice emboss over and over. The great thing about urethane is that it lasts a very long time and can be used repeatedly for consistent results. The durometer or hardness of the urethane can be customized using our special formulas to help when forming different thicknesses of metals or details in your patterns. Save time and money when you are on your next embossing project. We have sheets of urethane in stock. Please view the available sizes here and if you need a custom sized piece contact us here.

Depending on the resources, time and money available to you there may be the option and advantage of making a mold in house. We have plenty of customers that choose to make molds and send them to us for us to pour our highly durable K-Prene® urethane. The foreseen advantage is complete control of the mold and overall outcome of the part being produced resulting in the potential lowered costs of engineering and manufacturing of the mold in house. Of course this can create unforeseen problems and extend the amount of time it takes to complete the mold making process if we cannot correctly pour the part or there happens to be a mistake in the mold.

Because we are a urethane and mold making manufacturer we work with businesses like you, do this every day and can design molds that we know will end up working with our manufacturing processes. The idea behind having this service under one roof is to cut down on overall costs and time that it takes to complete a finished product. We are very competitive with our rates for engineering, mold making and machining as well as the urethane itself. We have a dedicated mold room to house your molds on site and only to be used for your production needs. After all of the time spent on communication, shipping and freight charges we strongly suggest you Contact Us to discuss your application with us before deciding to build molds in house.

In the event you can manage all of the above in house under cost and are prototyping – have small production runs it could work in your advantage to make molds at your facility and we are happy to consult with you on this. Contact Us for more information or call 1-800-345-0583

We manufacture and pour blocks of urethane for a customer that will further machine them for their particular application. This photo shows that we pour these very large blocks of 90A durometer urethane on various thicknesses of plate steel. The end user will then set them in a fixture for mill machining them as well as locate and drill all of the holes for a final product. The sky is the limit for these types of applications. Higher durometer urethane is easily machined to exacting tolerances while allowing for a final product that will be durable and forgivable for your application. You can trust Acrotech Inc. to provide you with the best and most consistent urethane in the industry. Contact Us for a quote on how this service could work for you and your business.

Do you have rollers that look like this? If so don’t hesitate to Contact Us.. We see rollers like this come through our doors every day. Many different industries use these types of rollers. Woodworking, Industrial Manufacturing and Conveyor lines use similar styles. Depending on what your rollers are handling they can wear in specific spots or deteriorate over time. Urethane is a likely choice for recovering due to its ability to withstand many different chemicals and materials with customized durometers or harnesses. Tuning your rollers for your particular application and pressures could make all of the difference.

Acrotech Inc. Supplies multiple race car teams with a little known part that helps dial in race car suspension for specific tracks and conditions. The urethane spring rubber insert. Sometimes changing out a spring in favor of height and rate can take more time than what is available. This is evident when it comes time to pit the car, when time is of the essence a simple removal or swap of a spring rubber to help dial in feel and dampening can make the difference on a podium finish or not. Our urethane spring rubbers are highly customizable for many common sized springs. The durometer or hardness of the urethane will increase the spring rate a little bit (40A Durometer) or a lot (95A Durometer) effectively without swapping springs. Testing or trial and error is case by case, we recommend to start with several sets in different durometers to test for your vehicle on your track. Wether it be Nascar® or your local dirt racing track. Get the edge over the competition and call us for urethane spring rubbers. Contact us for a Quote.
