Welcome to Thermokerámia!

We are a family business operating since 1990. From a small workshop employing just 2 people, we have grown into a company giving employment to 30 staff, producing across more than 3,000 square metres.

From the very beginning, we have continuously developed and refined our primary ceramic manufacturing technology — low-pressure injection moulding — resulting in the annual production of nearly 500,000 technical ceramic products that meet exacting dimensional and quality standards to the full satisfaction of our customers. about_intro_3
