THE HISTORY BEHIND JOSLYN MANUFACTURING

Precision and Reliability in Plastic Product Manufacturing

Privately owned and operated since 1946, Joslyn Manufacturing brings a creative and collaborative approach to the production of thermoformed plastic parts for original equipment manufacturers (OEMs) as well as many other industries.

Our business started in agricultural manufacturing—producing tractor seats for farmers near our headquarters in Macedonia, Ohio. In the early 1970s, we expanded our capabilities to include plastic sheet thermoforming, where we ran two small vacuum-forming machines out of a 5,000-square-foot facility.

Thermoformed Plastic Products for Multiple Industries

Today, Joslyn Manufacturing is one of the most experienced formed plastic manufacturers in Ohio. In our 105,000-square-foot facility, we fabricate thousands of products annually for customers in a wide range of industries—including medical, consumer products, and OEM parts.
