Full-service facility for the manufacture, finishing and thermal spray coating of machine and wear parts and components. Capacity to handle swing parts in excess of 18’ at a diameter of 50"

A Wide Range of Capabilities to Meet a Wide Range of Challenges

As our name suggests, our specialty is the spray coating of metal, carbide and ceramic protective coatings for industrial applications. But decades of thermal spraying experience has revealed the wisdom of centralizing responsibility for a completely manufactured, coated and ground component. Accordingly, our Allentown Pa. production facility is a full-service facility. We have the expertise, the equipment and the capabilities to manufacture complete components, including machine element, thermal spray coating, diamond grinding and solid ceramic structures. We routinely CNC manufacture titanium, stainless steel, and super alloy components complete with diamond ground thermal sprayed coatings of carbide, ceramic and other specialty alloy surfaces.

Large Handling Capacity

Whether your project calls for a small wear part or a large component, a limited production run or a large run, Longevity Coatings can handle the assignment. Our largest coating handling system can swing parts in excess of 18’ at a diameter of 50". In addition, our multiple, medium and small, specialized coating handling systems can accommodate high volume parts processing. Multi-axis computer-directed motion control systems as well as mechanical multi-spindle setups provide the handling apparatus for processing shafts, sleeves, hubs, balls, and numerous other coating applications.

Ancillary Services

In our diamond grinding, honing and lapping shop, we readily meet your most demanding specifications for size and surface finishes:

	•	Carbides ground and lapped to an extremely smooth 1Ra surface finish
	•	Plasma sprayed ceramics ground and lapped to a very fine 4Ra surface finish
	•	Diameter tolerance to .000l" (.0025mm)
	•	Solid carbide and ceramic parts

Plasma coating the inside surface of a large cyclone. This is both a compatibility and wear issue. In this case, the product being processed would exert wear on the vessel itself. The resulting wear could contaminate the product; accordingly, a plasma coating was applied to the cyclone interior. The coating was both wear-resistant and chemically inert—satisfying two crucial requirements

The cyclone shown above required a uniform interior coating. To accomplish this, Longevity mounted the cyclone on our largest lathe—a heavy-duty turning machine capable of handling components up to 19’ in length
