Harkness Industries produces several resins suitable for profile extrusion. The extrusion process for profiles is similar to sheet extrusion. The resin is fed into an extruder which melts the material and forces it through a die that gives it the desired shape. Additional processing is necessary to give the extruded profile its final contours. Profiles may...Read more

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...Read more

Injection molding technology has made major advances in the last 25 years, from largely a world of shoot-and-ship to doing as much as possible at the press — using automation to remove parts and assemble them, two-shot molding, even assembling parts inside the mold. Now instead of a big inspection department, constantly pulling parts off the...Read more
Every plastic part starts in a mold. Molds are classified into two main types, cold runner and hot runner. Each has its advantages and disadvantages. Your plastic injection molder will be able to give you the costs and benefits of using these different systems. However, by understanding the key differences of these technologies, you...Read more
Harkness Industries’ cast urethane shapes (sheet, tube, rod and bar) are well known for their extraordinary toughness, durability, and consistent quality. Our MP Series product line will improve service life by 10 to 20 times versus that of conventional rubbers and plastics. In the toughest abrasion environments, urethanes will outlast hardened steel by...Read more
Cast polyurethane can be readily turned, sawed, drilled, ground or milled. These and other secondary operations present many similarities to the machining of metal, but there are also some important differences. This following information is intended to provide some general guidelines for machining urethanes. See Also: The advantages of injection molding It is important to note that the material...Read more
The injection molding process has several advantages over other molding processes. It allows for the fast production of plastic parts with reduced waste and at low cost. The following is a short list of what you can expect from utilizing Injection Molding as your form of production.Read more
