Mantaline Corporation

Mantaline Corporation, headquartered in Mantua, Ohio, is an employee owned company of 225 associates that designs and manufactures polymer based (rubber and/or thermoplastic) extruded and molded sealing products.  Sealing products include door seals, window seals, engine compartment seals, sunroof seals, sleeves and tubing, and auxiliary seals for the transportation industry (heavy truck, automotive, RV, rail, off-road) and general industrial use.

 

Operating as a dedicated Tier Two Supplier we are a motivated team of individually accountable people working together in selected markets to deliver skillfully designed products to a very high quality customer base including heavy truck (Kenworth), off-road (John Deere), rail (GE), and more than twenty Tier One Automotive Suppliers to Honda, GM, Toyota, Nissan, FCA, Ford, Subaru, VW, BMW, and others.  Most of our customers trace their ownership to outside the USA; our engineers travel to “where the action is” on a regular basis.

 

Our Vision is: to grow to a position of leadership in the integrated polymer sealing system market (rubber and thermoplastic) as premier Tier Two Supplier through a gifted approach to customer problem-solving and global alliances all strategically developed to serve our region. 

 

To achieve our goal of serving the NAFTA marketplace efficiently we have sited manufacturing locations in Ohio, Texas, and northern Mexico: we have the right equipment and a trained workforce near our customers to minimize the cost of logistics, to reduce or eliminate inventories, and to provide attentive service.
