The engineering team at Precision Associates, Inc. (PAI) recognized the need to modernize their equipment in order to open up a new range of capabilities and increase their efficiency. After looking at several options, they chose to partner with DESMA on their first new injection molding press. Upon receiving and onboarding the first DESMA machine, [...]
Precision Associate's Sales Engineer, Dan Meydell presented the monthly Sealing Your Success Webinar, entitled "Friction Reducing Rubber Additives and Surface Treatments" for the International Sealing Distribution Association. Friction in many applications using rubber products and seals is undesirable and the reduction of said friction is a goal of many engineers and end users. While [...]
Youtuber, RCSubGuy uses the watertight, low-friction properties of U-Cup seals for a watertight seal on remote control submarines. PAI’s 70 durometer black-colored Buna N compound 5747 U-Cups resists pressure from water even at significant depths. Learn more
MINNEAPOLIS--Precision Associates, Inc. (PAI) is ramping up its production of several essential rubber components for ventilator manufacturer Ventec Life Systems. Ventec recently announced plans to partner with GM to increase the output of these crucial units in response to the COVID-19 pandemic. Critical patients suffering from the virus have difficulty breathing and require ventilator assistance [...]
Rubber Compound Data sheets usually display a number of physical properties as recorded from standard test methods. Among the most common are three measured on the Tensometer – Tensile Strength (at break), Ultimate Elongation, and Modulus of Elasticity. The Test The Tensometer stretches a specimen, or dumbbell, cut from a sheet of rubber, until it [...]
As the name implies, these O-Rings are used to seal Straight Threaded Tube Fittings. As with other O-Rings in static application designs, they make a seal between two mating components. Unlike most O-Rings, they are not completely housed in a rectangular groove or gland. The threaded male tubing fitting does contain a radiused partial groove [...]
The Manufacturers Alliance has recognized Precision Associates, Inc. (PAI) as the 2019 Manufacturer of the Year in the mid-size company category.
How does rubber get into food you ask? Food Processing machines have rubber seals in them. The seals are exposed to harsh chemicals during the cleaning and sanitizing process or can wear over time causing the rubber to breakdown. Seals made from rubber that have been compounded to withstand caustic chemicals should be used in [...]
Since 1955, Precision Associates Inc. has been proud to offer top-quality precision-molded rubber goods. We established our reputation by designing top-quality O-rings for everyday use. In 1956, cofounder Arnold Kadue noticed how ubiquitous O-rings were becoming in contemporary applications. However, these O-rings were also constructed from prohibitively expensive materials, and he directed PAI to find [...]
Rubber seals are used in numerous industries to prevent the unwanted leakage of liquids and gases in various components such as pumps, valves, pipe fittings, and vacuum seals, to name only a few. However, all seals are not created equally. Rubber seal design consists of several elements to ensure that the seal delivers optimal performance [...]
