Stern Rubber adds EJ Ironworks as a Customer

Gate Valves have long been a key part, manufactured here at Stern Rubber.  Our teamHydrant small.jpg has worked hard to perfect the process of bonding our rubber to a cast iron valves, so they will form a liquid tight seal in water mains across the country.  Our production of these parts has been done at both our Staples, and Aitkin facilities.  With our recent addition to our Aitkin plant, we took this opportunity to move our production of gate valves entirely over to this facility.  This transition, required us to transfer several pieces of equipment, including machining equipment and a few of our large presses from the Staples plant, and over to Aitkin, freeing space and personnel for new production opportunities at the Staples campus.  Along with our movement of machinery to Aitkin, we also added several new pieces of production equipment, including a rubber mill, overhead cranes, as well as a new press.

Valves small.jpgAlthough our production capabilities here at Stern are very diverse, we are always excited to bring in new customers, that want us to work with something we are already experienced in.  With our new expansion in Aitkin, and the addition of a new customer, we are excited to see how things continue to progress in 2018 with our company as a whole, as well as our new relationship with EJ Ironworks.

Masticated Rubber

The Mastication of Rubber

Masticated Rubber is a rubber compound made of reclaimed/ recycledAriens floor mat.png natural or synthetic rubber.  The term masticated rubber has come to mean a mixture of recycled rubber and fiber.

Uses for Masticated Rubber

Masticated rubber is a good choice for applications where superior hardness, tensile strength, and durability are required.  Due to the synthetic fiber cords, the material has high compressive strength, resistance to wear and tear, durability, and resistance to ozone and weathering.  Masticated rubber is extremely tough and durable, and is used in mining, railroad and trucking applications.

Mud flaps.pngThe masticated rubber that Stern Rubber uses is made from pre-consumer waste from tire manufacturers.  Our supplier purchases this uncured material, and re-mills it with nylon fiber to our specifications.

Because masticated is made from recycled materials, one of its greatest advantages is that it has a very economical cost.  Masticated rubber often costs less than 25% of the cost of virgin Natural, SBR or EPDM rubber.

Some of the applications for masticated rubber are automotive baffles, automotive air dam.jpglawn mower chutes, air dams, mud guards, mud flaps, agricultural cab mats, and grain deflectors.

If you have an application that you think may be a good fit for masticated rubber, contact us at or at 218-894-3898, or fill out our quote request sheet at

Barry Hirschey's First 1st Place on his KTM Mon, 08 May 2017 13:56:00 MDT All 4 Seasons in One Week. Welcome to Minnesota!

The weather in Stern Rubber’s back yard is extremely Boat with snow.jpginconsistent and the opening week of spring hasn’t been any different.  With highs reaching nearly 70 degrees on Saturday April 23rd, outdoor activists, golfers and really, everyone in the area thought summer was about to begin.

Yet, on Wednesday the 26th, only 3 days later, the tables turned and across the state with temperatures dropping below freezing, there was a blanket of snow covering most of the state, especially our area. Just north of Stern Rubber’s Cass Lake.jpgStaples facility in Bemidji, nearly 7 inches of snow accumulated, closing golf courses, slowing down traffic and making it seem, as though winter had never even left.

Although this strange cold snap came for a few days, it went away just as fast. With upper 50’s returning for the weekend and no snow in sight for a few days, the spring season will continue in with many warm weather firsts, including the Grandview golf opener at the The Pines 2.jpgPines and Preserve golf courses.  This event kicks off the opening of the golf season for 2017, and includes special guest the “Common Man” from KFAN radio in Minneapolis hitting the opening tee shot and hosting a radio show, with a concert in the parking lot at the Pines to cap things off.

The lakes area is ready to officially kick of the spring/summer season, but as most Minnesotan’s are used to, Mother Nature may have other ideas.

Polaris to add Victory Styling to Indian Line

Although Polaris decided to end the Victory line in 2017, the iconicVicotry cross-country.jpg
 style of these machines will not vanish forever.  As Polaris begins to pour their focus on bikes into Indian, they are not going to lose the iconic body style that came with the Victory line.

Launching two new touring models for the Indian line in 2017, including the Chieftain Limited and the Chieftain Elite, boasting all the tradition and ambiance of an Indian, with the style and flare of the Victory.  This merger of two models presents Indian with an evolutionary opportunity to take them from classic looking machines to the stunning touring bikes of today.

Cheiftain Limited.jpgThe Chieftain features Indian’s new massive Thunder Stroke 111-cubic inch engine, and custom in dash infotainment center, that includes navigation, and many other unique technology features.  All of this, paired with lots of chrome, large curved rear fenders, exposed 19 inch contrast cut aluminum wheels, and stylishly painted graphics, adds the original Victory flare to an already iconic brand.

These subtle yet stylish changes, bring a fresh feel to the already stunning designs within the Indian line.  The two new Chieftains brings Indian’s 2017 model total up to 12, showing that Polaris is moving aggressively in the right direction with this transition from Victory to Indian.  Riders and bike fanatics are all curious to see what Polaris does next, as it continues to grow the Indian brand.

Stern Rubber Helps With City Wide Park Cleanup

park_cleanup_2017.jpgOn Tuesday, April 4th, City of Staples held a city wide Community Parks cleanup day.  The city asked for groups and companies to volunteer to help with this effort. 

This was the first year that Stern Rubber had participated by allowing employees to help with the clean up during their work day.  We had 8 employees that spent several hours helping with this effort.  The group cleaned Wilson Park, as well as the new open area on the southeast corner of Airport Road and Prairie Ave. NE, and also cleaned along the Legacy Trail from the Legacy Gardens down to the overpass.
