Hoosier Pattern Launches 360 Virtual Tour

Hoosier Pattern is excited to announce the launch of our 360 Virtual Tour.

The inspiration behind this project came from you, our customers. Who wanted to tour our facility, but due to busy schedules, or extended traveling distances, you were unable to visit our company. In 2019, Hoosier Pattern’s president Keith Gerber decided that implementing a virtual tour is the best option to solve this problem. Immediately, we began implementing the steps to make this vision a reality.

Our goal was to have a virtual tour that communicates with our customers, local patrons, as well as students interested in Hoosier Pattern’s summer internship program. We wanted our audience to see the ins and outs of our innovative manufacturing process.

Our virtual tour is optimized for desktop, tablet, or smartphone devices.

The “i” dots throughout our virtual tour are clickable and will provide you with information about that specific area. Other features of our virtual tour include menu buttons at the bottom right corner that will bring up a blueprint of Hoosier Pattern’s facility. A gallery of pictures contained in our tour, a Google map link, and our LinkedIn page.


With all the concerns amid COVID-19, Hoosier Pattern is an essential business, and we’re taking this very seriously. One of the precautions we have implemented is to cancel all in-house, face-to-face meetings, including personal tours. Quite honestly, there is no better time to unveil the 360 Virtual Tour as a way to keep our business flowing normally while allowing customers to see our facility.

To see our virtual tour, please click here! No steel-toed boots, safety glasses, or sanitization requirements needed. Enjoy!

Hoosier Pattern and COVID-19

With the recent COVID-19 updates, Hoosier Pattern has decided to limit face to face meetings with customers and visitors and will be heavily utilizing the use of teleconferencing and web meetings with customers until further notice. It is our goal to not only keep our employees safe but to keep visitors safe by limiting contact.

If you want to fill out an application, please download our form via our website and email it to Truck drivers and deliveries are still being accepted with minimal contact and added sanitation measures.

Press Release - Plein Air Contest at HPI

Decatur, Indiana


The worlds of industry and the arts are seldom thought to have much in common.  And yet, on November 15, these two disparate worlds did indeed come together with an outcome far better than either group could have predicted.


Hoosier Pattern’s owner, Keith Gerber, came up with the idea of an Indoor Plein Air painting contest in which the artists would depict scenes from within his manufacturing plant, a building he and his 50 employees had occupied since 1997.  Artists were guaranteed the purchase of one artwork each.


With the assistance of local art event organizers, and Avon Waters, President of the Indiana Plein Air Painters Association, (IPAPA).  15 artists were invited to participate.


The artists came from as far away as Terre Haute and Springfield, OH.  They arrived fully prepared to work.  After a tour of the facility, and a brief explanation of Hoosier Pattern’s operations, sites were selected, easels were set up throughout the building (out of the way of forklifts and employees) and the artists got to work.  Many different types of mediums were used:  watercolor, oil, pastels, and acrylics.  With the exception of a brief break for lunch and a gathering for a group photo, the artists worked from 10:00 until 2:00.   



HPI employees voted on their three favorite works.  Many commented that it was difficult to choose only three because they were all so good.


Artists who participated were:

Sandy Hall, Greenfield, IN – FIRST PLACE

Lynne Dunnavant, Rosedale, IN – SECOND PLACE

Shelby Nower, Decatur, IN – THIRD PLACE

Avon Waters, Converse, IN

Diana Fair, Fort Wayne, IN

Tiffany Mendez, Decatur, IN

Curt Stanfield, Rosedale, IN

Darlene Vassil, Decatur, IN

Tim Swagerle, Peru, IN

John Kelty, Fort Wayne, IN

Robine Wright, Springfield, OH

Greg Mendez,  Decatur, IN

Rebecca Justice. Schaab – Auburn, IN

Christel Gutelius, Mecca, IN

Terry Pulley, Wabash, IN


Prizes amounts awarded were: 

1st Place - $750.00

2nd Place - $625.00

3rd Place - $500.00


HPI’s owner, Keith Gerber remarked that this event was clearly a win/win for both his company and the artists.  Hoosier Pattern will frame and proudly display the art in their front offices and reception area.  The artists were given the opportunity to paint an interior industrial setting instead of outside landscapes.  This was a first for them.  They also were able to paint indoors during November’s chilly temperatures.

*not all pieces of art are pictured

Keith hopes that by sharing news of this very successful event, other manufacturers and businesses might consider sponsoring similar events or would consider ways their companies might support the arts.  Both the artists and Hoosier Pattern employees thoroughly enjoyed this experience.  Should you have any questions about this particular event or if your company is interested in sponsoring a similar event, feel free to contact Laurie Mrvos, Human Resources at Hoosier Pattern:

HPI to host Plein Air Contest


Although Hoosier Pattern typically stays within the manufacturing lane serving a variety of industries across the board within the manufacturing realm, we think it is important to get involved with other industries to expand our knowledge and grow our minds. Hoosier Pattern is proud to announce that we are hosting a “Plein Air” Painting Contest on Friday, November 15th with the Indiana Plein Air Painters Association. Plein Air is in air quotes because typically Plein Air means an artist leaving the four walls of their studio and experiencing painting and drawing in the landscape. Since it’s cold out, we are bringing these artists inside the walls of HPI and having them set up their easels, break out their medium of choice and sit within the shop to paint whatever scene they see.

This is the first event of this kind at Hoosier and we were a little nervous about the turnout or if artists would even be interested in painting a “manufacturing” type scene. We set 10-12 artists as a nice goal and were elated when 16 artists signed up to participate and bring their talents to Hoosier. Artists will have the opportunity to take a tour of our facility, extract some 3D printed sand molds from the 3D sand printer, watch those molds be poured with our small on-site foundry and then pick the area of the shop they would like to paint. This contest was open to all artists and media so there will be paintings that range from oil, acrylic, watercolor, colored pencil, pastels or charcoal.

Each artist is guaranteed to have a painting bought by Hoosier Pattern and these paintings will be hung in our newly remodeled lobby for all visitors to see when they walk in the doors of HPI. In addition, there will be a first, second and third place prize given out after Hoosier Pattern employees vote on their favorites.

Keep an eye out on the blog as we will be posting the finished projects for the community to see and appreciate. We are very excited for this event and look forward to seeing what these artists create and come up with.

As the owner of Hoosier Pattern, I/we are excited to open our doors to artists, so through your eyes, you can capture the different areas of the business footprint. We hope that this day is as rewarding to you as we are sure it will be for years to come being able to showcase your talents in our front lobby common area. We look forward to employee-wide to judge your talents soon after this event. Good Luck to each of your participating.” – Keith Gerber, Owner of Hoosier Pattern

MFG Day at HPI

National Manufacturing Day isn't officially until October 4th, but HPI decided to celebrate a couple of days early. HPI held a MFG Day event for local students and educators where they were welcome to come into the shop, take a tour, ask some questions and see what goes on behind the doors of HPI on a day to day basis. Over 70 students from area schools came through our doors to see what goes on behind the scenes at HPI. Tours were given by employees that are currently going through the apprentice program as well as a few other full-time employees. Students were encouraged to ask any and all questions they had regarding the industry and what it is like to work within it. 


Stops on the tour included: the shop floor, saw area, CAD/CAM room, sand printing room, sand cleaning room, benching and rigging area and the quality lab. There was also a stop at a foundry that was up and running. Students got to watch as a real 3D printed sand mold got molten metal poured into it. Once the mold was cooled down a bit, it was broke open to reveal a gargoyle casting. 


The students toured the facility for about an hour and a half and then ended their tour with pizza and a MFG Day/Hoosier Pattern t-shirt. We take pride in doing everything we can to make sure that future generations see what goes on within our industry. We will always encourage students and schools to make sure students are exposed to skilled trades and will do everything in our power to make sure they have the opportunities to tour our job shadow any of the positions in our shop. It was a successful Manufacturing Day event and we look forward to future ones! 

HPI To Host Manufacturing Day Event for Students and Educators

Manufacturing Day is nationally recognized every year on the first Friday in October and is used to showcase the reality of modern manufacturing by encouraging thousands of companies and educational institutions around the nation to open their doors to students, parents, teachers, and community leaders.

Although Manufacturing Day falls on October 4th this year, Hoosier Pattern is opening its doors to students, educators, school officials, and local government officials to tour our facility and see what goes on day to day behind the doors at HPI. Guest will be able to check out each area of the shop as well as be able to talk with employees and ask any questions they may have.

Multiple CNC centers on the shop floor will be running and the 3D sand printers will be printing job boxes in real-time. There will also be a finished job box with 3D sand printed keychain molds inside. Visitors will be able to extract their own molds, clean them at a cleaning station and then take them to be poured here in the shop and be able to take a custom keychain home with them.

When visiting local schools and talking to local students, we always ask students what they think of when they hear the word “manufacturing”. We get answers like “dirty”, “low paying”, and “bad hours”. Hoosier Pattern strongly believes in encouraging the younger generation to explore careers in manufacturing and take every opportunity to show these students that those stereotypes are just simply not true.  We encourage all students and educators to join us on Wednesday, October 2nd at Hoosier Pattern as we help inspire the next generation of manufacturers.  

If you are an educator and want to get your class here for this event please contact Alyssa Corral at or directly at 260-706-4144

3D Printed Sand Molds and Cores for Pump Components at TPS 2019

In two weeks, HPI's Dave Rittmeyer and Alyssa Corral will be in Houston, Texas at the 48th Annual Turbomachinery and Pump Symposia. TPS is a worldwide event with exhibiting companies from all over the globe exchanging ideas to grow the industry further. TPS is known for its impact on the turbomachinery, pump, oil, gas and petrochemical power, aerospace, chemical and water industries. Typically there are over 4,500 attendees and 350 exhibiting companies from 45 different countries. The show floor spans over 200,000 square feet and is filled with industry experts demonstrating full-size equipment and products. 


HPI will be at booth #1226 with 3D printed sand molds and cores as well as some castings that were cast from like molds and cores. The HPI booth is always filled with plenty of videos and visual media to help answer any questions as well as information for customers and potential customers to take with them. If foundries have never poured the 3D printed sand, we encourage them to stop by the booth to get their badge scanned to have some free samples sent to them. 


Why Use 3D Printed Sand to Make Pump Components?

In a maximum of 2 weeks from the receipt of your purchase order, you can have a sand mold of your pump component ready to ship to the foundry of your choice. Don't have a foundry in mind? No problem. We have a network of foundries we work alongside to produce high-quality castings for our customers. The sand molds are ready to make a casting with no waiting for foundry tooling to be made, refurbished or changed to the latest engineering level. Castings get made faster and into your customer's hands quicker. This process is ideal for new prototypes, low volume pump requirements, and legacy pumps or their components.

The cost for 3D printed sand components, sand molds or sand cores is $0.13 per cubic inch. This is the cubic inch of the CAD build box of the sand component. No extra charge for complex designs or geometries. The only extra charges are if you want it NOW, like the next day NOW. Yes, we can do that. 

Complex geometries of your parts do not equate to higher costs to make your castings. You do not need to sacrifice your design for manufacturability. Complex core designs are 3D printed as one piece, thus reducing or eliminating assembly errors and foundry casting defects. No internal fins or mismatches. 3D printed foundry molds do not need traditional parting lines and flask sizes. This gives the foundry the freedom to gate, place risers, and feed the casting in the best way possible to produce the optimal casting. The freedom of pump design combined with the freedom of the foundry to manufacturing a pump component casting is a massive advancement for the pump industry. 

Complex pump component castings produced quickly and at a known cost is why manufacturers are turning to 3D printing as a solution to pump casting problems.


See you in two weeks, Houston! If you are not going to be at TPS this year but are still interested in 3D printed sand for your projects, please contact us.
