At NCC, we provide ceramic components for larger assembly units as well as assembly services for small scale products. In the past, we have produced things such as ends for fluorescent lamps and igniter components, all of which required multiple operations at our facility. We did all phases of the production, including formulating the ceramic material, forming the ceramic part, application of coatings as necessary and final assembly. We have done assemblies with both mechanical and adhesive methods. We are capable of providing our customers with a broad range of fabrication and assembly capabilities and we take pride in our quality parts and services.

Wear ceramic components are used in applications susceptible to high rates of abrasion. Common wear parts that are made from ceramics include:

Runners
Sand Blast Nozzles
Wire and Thread Guides

Specifications

Industries Served		Automotive Commercial Aerospace Electronics Fire Surpression Furnace Construction Heat Treatment Industrial Ignition Lighting Liquid Transfer Materials Handling Military Aerospace Radio/Radar Recreational

Example Parts Made		Bottle Cap Crimping Components Ends for Fluorescent Lamps Runners Sand Blasting Nozzles Small Metal Part Stamping Dies Thread Guides Wire Guides

Fabrication Capabilities		Here at NCC, we handle all aspects of ceramic production from the formulation of the ceramics themselves to glazing and finishing final parts. Our capabilities include: Ceramic Material Formulation Die/Tooling Fabrication Extrusion Pressing Machining CNC Machining Manual Milling Manual Turning Grinding Glazing Firing Packaging Shipping

Part Geometries		We can fabricate any shape you can think of- from simple to complex. We handle all types of cross sections including: Cylindrical Rectangular Tubular Trapezoidal

Size Range		Size ranges depend on ceramic material choice. Steatite: Min. Diameter - 0.125" Max Diameter - 5.250" Length - 30" Cordierite: Min. Diameter - 0.125" Max Diameter - 5.250" Length - 36" Alumina: Min. Diameter - 0.125" Max Diameter - 2.250" Length - 10" Zirconia: Min. Diameter - 0.125" Max Diameter - 1.500" Length - 8" Size range given in cylindrical dimensions. Equivilent dimensions for other geometries apply.

Tolerances		We can obtain ±0.001" tolerance for most operations. For less precise processes, we maintain ±0.005" tolerance.

Preferred Drawing Submission		DXF, PDF, IGS, DWG, STP and all other file formats. We will also take hand sketches.

Quality Control/Assurance Standard		The constant goal of NCC is a superior level of quality and sevice at competitive prices. Particular attention is given to the production of individual customer parts for both large and small runs. We implement a very sophisticated Quality Control process which we have our own customers certify. All parts that pass through our facility are visually and dimensionally inspected as well as calibrated, if necessary. Our engineering staff is available for counsel and recommendations that will satisfy your ceramic requirements.

Finishing Types		We use our in-house facilities as well as our relationships with outside vendors to supply our customers with the necessary finishing operations for their final parts including: Glazing - for aesthetics and maintenance purposes Teflon® Coating - for maintenance purposes Metalization - for assembly and conductive purposes

Secondary Operations

Metallization		Metalized ceramic can be used for a number of things, the primary being the bonding of the ceramic to metal components by soldering or brazing. The resulting assembly is more permanent than mechanical assemblies and can be used in areas in which mechanical assembly is not practical or desirable. It is often used in vacuum and panel feedthrough applications. Metalization is a thin coating of a metal material on the ceramic which provides an interface between the ceramic and the solder or brazing material used to bond to a metal component. Unmetalized sections of the part can also be glazed or Teflon coated. Alumina and steatite are the materials that we make that are used in this process. Size capabilities and consistent with the sizes for unmetalized components of the same material.

Ceramic Materials

Steatite		L3 Steatite - Good electrical properties, temperature capabilities to 1800° F, and high strength. A good choice for applications requiring good electrical insulation but not involving high frequency. L5 Steatite - Good electrical properties at normal and radio frequencies. High strength and ability to withstand temperatures to 1800° F. Applications include coil forms and other insulators in radio frequency applications and a wide range of electrical insulators where good electrical and mechanical properties are required. C10 Steatite - Our high thermal expansion body developed to facilitate ceramic glass to metal sealing while retaining the good electrical and mechanical characteristics of our other steatite bodies.

Cordierite		Porous Cordierite, with a low coefficient of thermal expansion has the ability to withstand thermal shock and temperatures to 2200° F. This is an excellent choice for applications such as element hangers and spacers in ovens and kilns, part holders for heat processing in relatively clean and dry environment, and electrical insulators applications such as gas ignition- again in relatively clean and dry environments. Vitrified Cordierite has most of the properties of the porous cordierite, but without the porosity. These characteristics make this material very useful where absorption would be a problem, such as oil ignition. It is easier to keep clean than the porous cordierite.

Alumina		We manufacture alumina components in four grades of purity: 92%, 95%, 96%, and 99.5% to meet a wide range of needs. All have good electrical and mechanical characteristics, are able to withstand elevated temperatures exceeding 2500° F, and have good wear properties. Applications include thread and wire guides,spark plugs and ignition devices, welding and sand blast nozzles, and electrical insulators in furnaces and ovens- including high vacuum applications.

Zirconia		Zirconia is often used in wear applications, but also in very high temperature environments. It has a high surface lubricity and can be manufactured with a high surface finish. It is good for things like thread and wire guides, industrial crimpers, and tooling for powder pressing.
