Used Osborn Foundry Equipment Machines

Osborn Sand Molding equipment, often referred to as "Osborn Molding Machines," was a key line of products produced by the Osborn Manufacturing Company, a well-known name in the foundry industry. These machines were used for creating sand molds in which molten metal would be poured to produce cast metal parts.

Here’s an overview of Osborn Sand Molding Equipment:

  1. Molding Machines: Osborn's sand molding machines were designed to produce precise sand molds for metal casting. These machines typically included jolt, squeeze, and jolt-squeeze molding machines, which used mechanical or pneumatic action to compact the sand around a pattern, forming a mold cavity.

  2. Jolt-Squeeze Machines: These are among the most common types of sand molding equipment produced by Osborn. The "jolt" action involves raising and dropping the sand-filled mold box to compact the sand, while the "squeeze" action compresses the sand further to ensure a dense and uniform mold.

  3. Automatic Molding Lines: Osborn also developed automatic molding lines, which integrated multiple steps of the molding process into a continuous operation. These lines typically included pattern exchange, sand filling, compaction, mold removal, and mold transportation systems, allowing for higher production rates and consistency.

  4. Rollover Machines: Osborn’s rollover machines were used to invert the mold after it was formed, allowing for easy removal of the pattern without damaging the mold cavity.

  5. Sand Handling Equipment: In addition to molding machines, Osborn provided equipment for sand handling, mixing, and reclaiming. This equipment ensured that the sand used in molds was of consistent quality and could be reused efficiently.

  6. Specialized Molding Systems: Osborn also produced specialized systems for complex molding applications, such as flaskless molding machines, which created molds without the need for a flask (the frame that holds the sand mold).

Osborn's sand molding equipment was widely used in foundries to produce a variety of metal castings, from small precision parts to large industrial components. The company was known for the durability and reliability of its machines, which contributed significantly to the efficiency and quality of casting operations.
