Year Founded:


For over a century, Ceramaret has dedicated itself to shaping and polishing hard materials. Founded during the industrialization of the watchmaking sector, Ceramaret has been successful in opening itself up to new technology thanks to a visionary development policy. 

Formerly called Maret SA, a family company established in Le Locle in 1907, it relocated to Bôle in 1952. The size of the factory was increased over time. Maret SA also expanded its operations into the manufacturing and machining of components from ultra-hard materials. In 2005, the company changed its name and became Ceramaret SA, reflecting its focus on advanced ceramics. Maillard Frères SA a company specialized in the drilling, boring, and turning of synthetic rubies, sapphires, and other advanced ceramics, joined the Ceramaret SA group in 2009.This entity has been fully integrated into Ceramaret SA in 2016.

After having been controlled by the Maret family for three generations, the company became part of the industrial group MK Holding SA from 1991 to 2013. MK Holding was founded by Mr. Martin E. Knechtli. Through his strong personal commitment he gave the company its actual footprint in the field of advanced technical ceramics. Under his leadership Ceramaret could further innovate and grow to its current size, while doubling the number of its employees.

Since the 1st of January 2014, Ceramaret SA has been part of the KOWEMA Beteiligungs AG group in Baar (ZG).

The shaping and polishing of ultra-hard materials require special expertise and equipment.

With its modern plant and equipment, and by drawing on the skills and knowledge of close to 170 employees, Ceramaret is one of the world's leaders in the manufacture and machining of high-precision advanced ceramic components and other ultra-hard materials.

Everything starts with ceramic engineering excellence

Thanks to its technical experience, Ceramaret is able to work with you to design high-precision ceramic parts based on the specific properties of the chosen materials. Our active involvement in the earliest phases of the production of your ceramic parts is the guarantee that you'll receive technical solutions at competitive prices. Our in-house capabilities allow us to design unique tools for the different stages in the manufacturing process.

Put our knowledge to work for your prototyping needs

Ceramaret is putting its experience to work to assist you with your prototype development. You need a series production, but you have to validate your product design in the first stage against alternative options. Our Prototypes department will provide you with functional parts as expeditiously as possible. This stage will also enable you to optimize the industrialization of your product.
High volume high precision ceramic forming process

Production of near-net shape components thanks to various pressing techniques

The various pressing techniques will enable you to achieve the desired shape of the ceramic part to meet your product requirements. Our mastery of tool design and the manufacturing process enable us to achieve unmatched dimensional and geometric precision.

Debinding and sintering of ceramics

Ceramic powders contain binding agents (polymers for example) that facilitate the compacting and shaping of the parts.These binding agents are removed from the part during the debinding process consisting in heating the shaped parts at high temperatures.

Sintering, the process for the compacting of ceramic particles, uses high temperatures (up to 1600 -1800°) to heat the shaped and debinded parts over a long period of time.

Specifically designed furnaces are required to carry out these two processes.

High-precision machining

When your dimensional or geometric product specifications cannot be guaranteed by the shaping and sintering processes, high-precision machining processess are used in the manufacturing stage.

Cylindrical grinders allow us to obtain excellent geometric and dimensional tolerances.

4 axes and 5 axes  machining centers are used for the high-precision machining of the most complex parts.

Single (FLM) or double-disk (DLM) grinding machines enable us to obtain extraordinary surface finishes.

Automated production facilities are reserved for mass-produced parts.

Thanks to a finishing process using abrasive circular grinders, we are able to obtain exceptional cylindricity and an unparalleled surface finish for ceramic pivots and pistons.

Surface marking of ceramic parts may be carried out through laser technology.

Each part produced by Ceramaret is subjected to an automatic cleaning procedure at the end of the manufacturing process.

Quality control

Our many ISO certifications - 9001 : 2008, ISO 14001 : 2004, OHSAS 18001 : 2007 et ISO 13485 : 2012 demonstrate the importance of quality and safety to our company. Our quality control system is organized for matrix and transverse testing, at all stages of the manufacturing process.

Employees are expected to take personal responsibily for their performance to avoid any loss of quality.The compliance of our production, in accordance with out clients' needs, is guaranteed by AQL-level or 100% inspections.
