Engineering & Manufacturing

At Steelceram we help you go from a problem to a ceramic part that works: we choose the material with you, review the drawing to adapt it to ceramics and support you from prototype to series. We make custom technical ceramics in our workshop in El Bruc, near Barcelona, with several forming and finishing processes.

Materials

We choose the material with you

Each ceramic solves a different problem: wear, impact, temperature, sudden temperature changes, chemical attack or current. That is why we start with how the part works, not with the material. With that information we recommend the grade and explain why. You can compare the grades in Ceramic materials.

Manufacturing

We review the drawing for ceramics

A part designed for metal cannot always be copied as is in ceramic. We review your drawing and propose the changes needed so that the part can be made and lasts: the geometry, the thicknesses and the tolerances you really need. If you do not have a drawing, we can start from a sample or a photo of the current part.

Manufacturing

How we make it

  • Forming. Depending on the shape of the part and the material: isostatic pressing, uniaxial pressing, injection molding or extrusion.
  • Machining. Many parts are machined in the green state, before sintering, when the material is still easy to work.
  • Finishing. Grinding, lapping and mirror polishing, depending on what the part requires.

Each material allows certain processes and finishes. You will see them on the page of each grade.

Manufacturing

Tolerances and surface finish

The tolerance and the roughness that can be achieved depend on the material and on the part. For example, in 99.7% alumina the tightest tolerance is ± 2 µm and the minimum roughness is Ra 0.1 µm. These are typical values for guidance only; they are not a specification: state on the drawing what you need and we will confirm it in the quote.

Manufacturing

From prototype to series

First we make a prototype for you to test on your machine. Indicative lead time: 2-4 weeks. With the prototype approved, we make the series, in 4-8 weeks depending on workload and project complexity. The full process is in Custom parts.

Questions

Frequently asked questions about engineering and manufacturing

Do you help me choose the material?

Yes. Tell us what wears the part, what temperature it works at, what medium it is in contact with or what current it carries, and we will recommend the grade.

Can you modify my drawing?

We propose changes when the part needs them to be made in ceramic or to last longer. You decide whether to accept them.

Where do you manufacture?

In our workshop in El Bruc, near Barcelona.

What tolerances can you achieve?

It depends on the material and on the geometry. On the page of each grade you will see the typical tolerance and roughness; for your part, we confirm them in the quote.

Quote

Do you have a part that keeps failing?

Send us the drawing or a photo and tell us how the part works. We will tell you whether ceramics solve the problem and in which material.
