If you’re considering a natural urethane for your next manufacturing project, here’s what you need to know about possible color variances. The color of natural polyurethane can vary from supplier to supplier, and is impacted by a variety of environmental factors. Typically, they vary between a light tan (almost yellow) to medium-dark amber (almost green). No...Read more
Cast Urethane is known for its roughness, durability, and quality. Here’s what you need to know about our standard urethane products.Read more
- Cast urethane products improve service life. Our MP Series product line, for example, can improve service life 10-20x when compared to conventional rubber or plastics. Urethanes also outlast hardened steel by 5-1!

This month, we continue our guide to machining cast polyurethane elastomers and will be taking a closer look at knifing, milling, drilling, and grinding: Knifing: It’s important that the knife tool be as thin and sharp as possible to get the most precise cuts when close tolerances are present. For metals with hardnesses between 70A and...Read more
When you need extreme wear resistance that will outlast hardened steel by a factor of 5-1, use abrasion-resistant polyurethane liners in your next plastics manufacturing project. These polyurethane liners are ideal for harsh friction environments like bins, hoppers, turnheads, chutes, and discharges. Light-weight and noise damping, these polyurethane liners help protect your critical machinery from everyday,...Read more
Atlanta High Museum is currently holding it's MERRY GO ZOO exhibit. MERRY GO ZOO is an interactive art display that is basically a polyurethane display. "Inspired to create a playful, twenty-first-century version of an outdoor public sculpture, Hayon has designed four large-scale, vibrantly colored, kinetic structures for Merry Go Zoo. Visitors can interact with the structures either by spinning on...Read more
We wanted to share an interesting, successful project we worked on recently with our client, ProBatter Sports. ProBatter Sports has been designing and supplying state-of-the-art pitching systems since 1999. Mike Suba, VP of Engineering came to Harkness with two goals in mind: 1) Improving the performance of the urethane in ProBatter’s current pitching system and 2)...Read more
At Harkness Industries, we offer both injection molding and cast urethane. Understanding the difference between these two types of products can make a big difference in your bottom line. Injection Molding Injection molding starts with the creation of what is called a hard tool. Think of this like a mold, a hard mold. The...Read more
Finding parts for old equipment can be difficult or even impossible depending upon the age. So when a machine is still capable of years of performance yet a gasket goes that can't be found the answer is to get a new one custom made to continues the life of the equipment. At Harkness Industries,...Read more
Injection molding is great for high volumes, but when it comes to small runs, what you really need is a cast urethane process. That's what makes it ideal for prototypes. Cast urethane processes are fast and cost-effective so whether it's the medical equipment industry or robotics, a durable plastic component can be made quickly at a...Read more
