ヤマキ電器 Product Lineup

1. Bearings We were commissioned to manufacture zirconia bearing stones, and as a result of our discussions, it was decided to deliver them as completed parts. We are incorporating them into screws and delivering them. 2. Various Crucibles We select shapes and materials according to the customer's application and manufacture them in the desired shape. Materials: Alumina, Zirconia, Fused Silica, Mullite, Titanium Aluminum Oxide 3. Sauce Containers for Eel We received feedback from an eel restaurant that they wanted to create a warm and flavorful container instead of a plastic sauce container for takeout. We collaborated with them on this project. Inspired by the restaurant's spirit of exploring new endeavors while preserving tradition, we have developed a product that embodies their requests as a long-established ceramics manufacturer. 4. Audio-related We sell original products such as headshells and insulators, but we also accept contract manufacturing. Additionally, we manufacture sockets and insulators used in other audio products on a contract basis. We also accept orders, prototypes, and production for ceramics, heaters, quartz glass, and more.
