Our Unrivaled Capabilities

Ortech specializes in high tolerance ceramic machining, grinding and polishing of unfired (‘green’) and fired ceramics.  Our state-of-the-art equipment allows us to offer a variety of ceramic services include:

suitable for the manufacture of uniformly compressed blanks and large parts that are appropriate for machining in the green state. Simple rubber moulds determine the initial form.

This type of forming is well-suited to the manufacture of exacting prototypes and small series, but for some products can also be fully automated (spark plugs, grinding balls, small pistons, welding nozzles).

Is used to manufacture mass-produced precision ceramic products. Non-clumping granulates are compressed in steel dies designed appropriately for the part to be manufactured. The high cost for the dies (sometimes made of carbide) can only usually be justified for large runs.

Dry pressing ceramic is the most economic process for large production runs, and is suitable for both simple and complex geometries. Depressions and holes are normally only designed in the pressing direction.
Depending on the design of the ceramic dry pressing machine, components ranging in size from tiles down to match heads can be manufactured. Small discs or plates can be pressed with thicknesses of around 0.8 or 1.0 mm. The tape casting process is more suitable for even thinner, flatter components. It is still possible to manufacture fine ridgesor similar structures on the component if the granulate being pressed can effectively fill hollows in the pressing tool, and provided it is possible to create the necessary tool.

Ceramic injection molding is ideal for high-volume production of complex, tight-tolerance components, ceramic injection molding offers significant advantages over conventional forming methods:
• Cost-effective technique for complex designs
• Ability to produce net or near-net shape parts
• Very tight tolerance control
• Low-cost, high-volume manufacturing runs
We use a variety of ceramic injection molding materials such as 99.8% alumina oxide, 96% alumina oxide and zirconia. Ortech refinement of alumina to 99.8% purity provides for more dense, harder, more abrasion resistant parts than those made by other processes, which speeds up the manufacturing process, and substantially reduces manufacturing cost! The resulting ceramic injection molding parts are superior in quality, and lower in cost.

This is what our clients say!

A few words to mentionne that we have received the ceramic parts and we want to underline the excellent work done on the manufacturing.

You have delivered quality parts within very good tolerances. These parts will fit perfectly in our preproduction engines. We expect to go in production late this year or early 2016. We will retain Ortech as our favored supplier for these parts.

Again, thank you very much.

Best Regards,
