Production Process of Automotive New Energy Ceramics

Material Selection and Preparation	High-purity ceramic powder is carefully selected as the raw material, which must possess excellent electrical insulation properties and mechanical strength to adapt to the high voltage and temperature variations in new energy vehicles.
Mold Design and Manufacturing	Molds are designed and manufactured with high precision according to the specifications and shape requirements of the fuse. The quality of the mold directly affects the dimensional accuracy and surface finish of the final product.
Molding Process	The ceramic powder is pressed into shape using molds. This step requires precise control of pressure and time to ensure that the formed ceramic body is uniformly dense, free of bubbles and cracks.
Sintering Process	The molded ceramic body needs to be sintered at high temperatures to increase its strength and stability. The control of sintering temperature and time is crucial for the final product's performance.
Machining	The sintered ceramic body may require further machining, such as cutting, grinding, etc., to achieve the precise dimensions and surface requirements as per the design drawings.
Assembly and Testing	The ceramic body of the fuse is assembled with metal parts (such as bolts, contacts, etc.), and electrical and mechanical performance tests are conducted to ensure the product meets safety standards.
Quality Inspection and Packaging	Finally, the finished products undergo strict quality inspections, including appearance checks, dimension measurements, and electrical performance tests. Qualified products are then packaged and prepared for shipment.

FAQ

Q: Why are ceramic materials important in electrical components?

A: Provide high insulation resistivity, low dielectric loss, and optimal dielectric properties across temperatures and frequencies, essential for ensuring electrical insulation.

Q: How are ceramics used in the automotive industry?

A: Advanced ceramics materials are incorporated into automotive designs when demanding conditions require a material that is robust and reliable. The thermal and electrical properties of ceramic materials allow them to be used in a variety of sensors, mechanical seals, ceramic bearings, and valves.

Q: Do ceramic bearings crack?

A: Silicon nitride ceramic bearings are widely used for their excellent performance. However, due to their special manufacturing method, cracks will occur on ceramic ball surface, and this initial surface crack will propagate under the action of cyclic stress, which will lead to material spalling.

Q: Is it worth upgrading to ceramic bearings?

A: Ceramic bearings can handle forces and loads that steel bearings can't, and. ceramic bearings will last longer than steel bearings.

Q: Should ceramic bearings be oiled?

A: No, full ceramic bearings can be run completely dry. They do not need lubrication to run. Ceramic is non-porous, unlike steel, as a result it is virtually frictionless. Ceramic also dissipates heat very quickly, which is the same reason they use it on the underside of the space shuttle.

Q: How do you maintain ceramic bearings?

A: Full ceramic bearings are maintenance free. However, they can be washed using regular tap water or a standard bearing cleaner product if required. Make sure the bearing is completely dry before replacing it. These bearings do not need lubricant to operate, so there is no need to add an oil or grease at this stage.
