Our Capabilities

Maynard's primary activity is the manufacturing of carbon and low alloy steel castings ranging in weight from 100 to 65,000 pounds. The versatility of the company's systems and facilities is critical to its long-term sustainability.

Four electric arc furnaces with capacities ranging from 10,000 to 70,000 pounds are available for steel melting. Basic linings are used in furnaces to help with steel processing and to improve physical properties.

Bottom pour ladles with capacities ranging from 10,000 to 80,000 pounds are used for pouring and molten metal treatment. Multiple ladles are used to pour larger castings, with a combined pour weight of over 120,000 pounds. Using porous plug argon stirring and calcium, iron, or titanium wire treatment, the most up-to-date clean steel technology is used.

Molds are prepared using both green sand and chemically bonded sand processes. Castings in smaller size ranges, typically 100 pounds to 2000 pounds, are produced in the green sand process on one of six molding centers. Chemically bonded molding processes are used for larger castings and selected smaller specialty castings where particular surface or dimensional requirements dictate. Ceramic tile gating systems and specialty facing sands are utilized extensively.

To meet a wide range of casting needs, various flask sizes are available. Flasks come in sizes ranging from 24′′ 24′′ to 192′′ 192′′ and 120′′ 240′′.

Core processes include oil sand, shell, -C02, and no-bake. A variety of core making machines and techniques is available to support the molding centers.
