About Joslyn Manufacturing

Get to know the plastic thermoforming professionals

Privately owned and operated since 1946, Joslyn brings a creative and collaborative approach to the production of thermoformed plastic components for original equipment manufacturers (OEMs) and point-of-purchase display companies.

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

Thermoforming experience for many industries

Today, we’re one of the most experienced formed plastic manufacturers in Ohio. In our 105,000-square-foot facility, we fabricate thousands of products per year for customers in a wide range of industries, including medical, consumer product and OEM component parts. Our state-of-the-art technology includes an array of heavy- and light-gauge thermoformers, computer numerical controlled (CNC) routers and trim presses.

We are proud of our reliable, proven processes—as well as our versatility and innovation—when helping customers create their most challenging products.

Known for transparency, integrity and customer collaboration, Joslyn’s engineering and manufacturing teams are ready to serve you.
