Intricate Machining
Here at Ceramic Substrates & Components Limited with our generations of experience in the precision ceramic industry, we have developed some unique techniques and cutters which enable us to machine incredibly fine and intricate tiny components, complementing the more industrial and commercial sized components.
Many Government organisations along with Scientific and Research Institutes and Universities worldwide use our facilities manned by highly skilled Engineers to fulfil many of their requirements, along with customers ranging from F1 and Super cars through to Aerospace.
We pride ourselves not only on our supreme quality but also our impressive long standing customer base.
Nuclear-related experiments
Since Macor MGC is not dimensionally affected by irradiation, small cubes of the material are machined to a tolerance of one micron and are used as a reference piece to measure dimensional change in other materials.
Welding nozzles
Welding equipment manufacturers are using Macor MGC as a nozzle on the tips of oxyacetylene torches. The material is nonwetting characteristic means molten particles wont adhere to and decrease the effectiveness of the nozzle.
Fixtures
Macor MGC is used as an electrode support and burner block in several industrial high heat, electrical cutting operations due to its low thermal conductivity and excellent electrical properties.
Medical Equipment
Producers of medical components are intrigued by Macor MGC's inertness, precise machinability and dimensional stability.
Conclusion
When you need the performance of a technical ceramic (high use temperature, electrical resistivity, zero porosity) and your application demands the ready fabrication of a complicated shape look at Macor MGC. It will lower costs and substantially reduce the time between design and actual use.
