Bunting Bearings Completes Casting Plant Expansion

Bunting Bearings recently completed a large expansion to our Delta, OH, centrifugal casting plant. Centrifugal casting is one of our main specialties, and our customers value our ability to create high-value, cost-effective centrifugal castings that can be machined to a finished product. With this new expansion, we’re excited to further expand on our abilities to provide the highest quality casting services to our clients.

Here’s an overview of our casting plant expansion and how it will benefit our capabilities moving forward:

Our Casting Plant Expansion

We invested in an extension to our plant to bring new value to our customers. With our new plant, we can now produce longer and larger centrifugal castings with lead times of 2–4 weeks and expedited delivery times of 48–72 hours.

We also dedicated new resources to our machine shop in Holland, OH. We installed five new live tooling machining centers as well as a vertical turret lathe to handle larger longer centrifugal castings.

New Casting Specifications

Our new equipment has enabled us to produce larger casting volumes at optimal efficiency. With our expanded capabilities, we can:

• Pour vertical castings with a size range of 3” up to 36” outside diameter as well as horizontal castings of 27” diameter and 60” length
• Achieve tighter grain structures, leading to improved physical properties
• Fill low-, medium-, and high-volume orders
• Perform QC testing at our in-house laboratory to ASTM B271– and ASTM B22.

Understanding Centrifugal Casting and Its Advantages

What is Centrifugal Casting?

Centrifugal casting is in effect “liquid forging.” Molten bronze is forced against the mold wall under moderately high pressure. Centrifugal force causes “an object moving in a curve to be pushed away from the curve’s center.” This force, combined with the rapid cooling effect of the cold mold induces directional solidification across the casting wall under a forced feeding condition.

What Are the Benefits of Centrifugal Casting?

The combination of centrifugal force and rapid cooling improves the density of the cast metal and increases the actual mechanical properties, while providing a uniform metallurgical structure. Therefore, products will have improved strength, durability, and performance.

What Materials Are Used?

Bunting Bearings is a U.S. supplier of centrifugal castings and manufactures a wide range of sizes in Leaded Tin Bronzes, Aluminum Bronzes, Manganese Bronzes and No Lead Bronzes. Centrifugal castings are generally sold in the semi-finished condition to ensure the customer receives a high quality casting with minimal machining required to meet the finished dimensions.

The Bunting Bearings Difference

Bunting Bearings is a premier bearing and bar manufacturer that has perfected the production process. Our lead time is virtually unmatched, and is typically 1 to 2 weeks, however it can even be as little as 48 hours.

Centrifugal casting is one of the ways that Bunting supplements our continuous cast offerings to our customers. Continuous casting still represents a tremendous value product with high quality combined with minimal clean up stock allowance. However when smaller quantities, larger sizes and non-standard alloys are what is required the cost effective solution is a Bunting centrifugal casting.
