Custom Project? Go Urethane!

Ready to get started on you next project? Urethane is an amazing choice for your next custom mold project.

What exactly makes Urethane such a great choice? It's physical properties allow it to be the ultimate "tough guy" when it comes to molding materials. Urethane possesses:

  • Outstanding Abrasion Resistance
  • Excellent Cut...

Homerun for Harkness!

  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)...

New Gaskets for Old Equipment

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,...

Urethane Outperforms in Construction

Concrete is a big part of construction and yet, wood and other materials continue to be the most common choice for concrete molds. Sure for foundations, and large areas, that may make the most sense, but when it comes to footings, concrete stamping and other smaller items, urethane molds are impossible to beat. Urethane is Read more

High Volumes, Minimal Waste with Injection Molding

In previous posts, we've mentioned that injection molding is very efficient for large production numbers, but just how it's so efficient is often a mystery to those outside of the industry. It begins with the mold itself. When we get specs from a client, we ensure our molds are absolutely precise to reduce the...

Prototype? Cast Urethane is Ideal

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...

Molding – Understanding the Difference Between Injection and Cast

Your project is unique to your needs and determining which process to use comes down to a few key differences in the production processes between urethane cast molding and injection molding. First, let's consider the similarities: Both processes allow for a multitude of colors, soft or rigid durometeres and the ability to "wrap" or cast around...

Jumbo Pour!

Harkness grows its aerospace business by expanding into Guerin urethane forming pads in a big way! In March 2015, Harkness produced a “Jumbo” forming pad for an 800 ton press. The 50” diameter x 10” thick pad weighed more than 900 pounds once completed and became single largest part that Harkness has ever manufactured. Guerin pad forming...

The Capabilities of Custom Urethane

Urethane's unique physical properties allow it to be molded into thousands of custom parts. Because of it's abrasion resistance, high load capability, and superior dynamic properties, Urethane is the perfect material for creating custom parts. When creating sometimes intricately designed custom shapes, urethane will begin as a rod, tube, sheet or bar. This shape is...
