Manufacturers Strengthen the Economy

October is Manufacturing Month. It’s an ideal time to highlight the continued relevance of manufacturing in the United States. Advanced manufacturing methods usher in economic growth. They drive new career opportunities and the demand for skilled workers.

Jef-Scot Metal (JSM) Industries is a longtime Centerville manufacturer and subsidiary of Tri-State Cast Technologies. The aluminum foundry, bought by Andy Darien in 1978, produces high quality sand castings for a variety of industries, including agriculture, marine, oil, aviation, transportation and more.

JSM now has affiliated operations in Kansas, Florida, Michigan and Qingdao, China. It ships products to Mexico, Canada and 29 U.S. states. “Our goal is to supply the highest quality aluminum castings to the global community,” says Amy Stephens, who serves as the office and human resource manager.

In recent years, JSM’s operation has grown significantly. Since 2016, it has doubled its property size and added about 10,000 square feet of floor space, which enabled room for additional machinery for sand preparation, mold handling, pouring, casting and finishing. It also added heat treat and no bake molding operations to its line. JSM can now produce larger molds for castings weighing up to 200 pounds.

JSM also serves as a supply chain manager in that it can provide finished components ready for assembly. It does this by supplying castings that are machined, anodized and in some cases include subassemblies. B&K Machining has become a very important local partner in this effort.

At full capacity, the Centerville plant will employ about 30 people. The local facility is overseen by General Manager Ryan Stephens, who has more than 20 years of experience in the foundry industry.

The company is community minded. It has supported many youth baseball, softball and soccer teams in Centerville over the years, as well as being an active member of the Centerville Athletic Booster Club. It is also a supporting member of the Appanoose Economic Development Corporation

JSM aims to be a good employer as well as corporate citizen by offering top notch customer service and unique, quality products. “JSM values its customers and employees and strives to be a better supplier and employer through communication, being proactive and seeking feedback,” says Stephens.

The company holds values such as fairness and respect in high regard. According to Stephens, JSM’s goal is to earn the respect of employees, suppliers, competitors, customers and the community.

“We hope to create an environment in which our customers will be well-served, our employees can work safely and productively, and our community is proud for us to be a part of it.”
