Tantalum is characterized by its high density, extremely high melting point (3,017°C), and excellent corrosion resistance. Being extraordinarily resistant to heat, it is classified as a refractory metal.
We have a new CNC machining center brought in our factory. It is a 3-axis machining center and will be used for machining of ceramics. Although the challenging situation caused by COVID-19 still remains all around the world, the situation in the semiconductor industry has gradually been recovered from a severe recession last year. Thanks to the recovering, we survive. It led to the inves...
Silicon Carbide (SiC) – Custom Machined Parts
Silicon Carbide has very good mechanical properties and maintains its strength even at extremely high temperatures. It also has excellent resistance to acids, alkalis and molten salts up to 800°C. These exceptional properties make SiC suitable in applications requiring great resistance to wear, thermal shock and corros...
Zirconium Dioxide, commonly known as Zirconia, is a high-performance ceramic material which exhibits excellent mechanical properties such as high hardness and fracture toughness. This makes zirconia ideal for a variety of wear resistance applications.
It is difficult to manufacture zirconia in large sizes compared to other oxide materials like alumina. In addition, zirconia is a r...
Alumina, also known as Aluminum Oxide, is the most popular ceramic material. It is a relatively low cost ceramic material with good machinability and has a very wide range of applications.

Many precision parts have been made in common metallic materials. But we machine exotic hard materials and make the same parts.”
Top Seiko provides high precision and micro machining services for a wide variety of exotic hard materials. With our well-equipped & maintained facilities combined with our in-depth knowledge and extensive machining experience of hard materials, we manufacture the highest quality custom machined parts.
Many parts require a hole drilling process. It is one of the most common and basic machining processes. Top Seiko excels at machining holes in high precision.
Comparing to common metals, ceramics is a difficult material to machine in 3D shapes. That is the same for tungsten and molybdenum. Top Seiko has been trying machining of 3D shapes of those materials for a decade and achieved in many cases.
Top Seiko excels at deep hole drilling. When you need precision deep holes in ceramics, glasses, and refractory metals, please feel free to contact us!
We offer material selection services as well.
Our deep knowledge of materials enables us to suggest the best material that will solve your problem. Also, when you do not know what material to use, we would be able to assist you to find the best one according to the application and the properties you need.
Since its establishment, Top Seiko Co., Ltd. has been developing the processing technology of Aluminum Nitride. This material is typically used for heat sinks, substrates, heaters because of the heat resistance and high thermal conductivity.
Top Seiko Co., Ltd. specializes in development and manufacturing of high precision machined fused quartz glass parts.
All of our engineers are experienced in precision machining of quartz glass and strive to surpass customer expectations. We offer the comprehensive shapes of quartz glass and fused silica products.
Top Seiko has been processing a variety of machinable ceramics such as Photoveel, Macerite, Macor, Rescor and Shapal Hi-M Soft(aluminum nitride+boron nitride).
