Precision Alumina Ceramic Shims

Our precision alumina ceramic shims are ultra-thin ceramic gaskets used for gap adjustment of precision equipment. They have extremely high dimensional accuracy and flatness, and at the same time have the characteristics of alumina ceramic insulation, wear resistance and high temperature resistance. They can achieve precise gap control in precision assembly, and at the same time play the role of insulation and wear protection. Compared with metal shims, precision alumina ceramic shims have higher hardness, are not easy to deform and wear, have good dimensional stability, and will not expand and contract due to temperature changes. They can maintain precise adjustment accuracy for a long time, and are ideal adjustment elements in the fields of precision machinery, electronic equipment and bearing assembly.

Our precision alumina ceramic shims are prepared by high-precision grinding processing, with thickness tolerance controlled at micron level, high parallelism of upper and lower surfaces, good surface finish, no burrs and no scratches, and can perfectly fit the assembly surface. The products support customization of different thicknesses, shapes and sizes, and can process various gasket forms such as round, square and special-shaped according to customers' assembly needs, and can also process positioning holes and slots on demand. Each precision alumina ceramic shim undergoes thickness, parallelism and appearance inspection before leaving the factory to ensure that the product accuracy meets the standard. With stable high-precision quality, our products have been widely used in the assembly of various precision equipment.

We support various customization services for precision alumina ceramic shims, and can customize alumina ceramic shims with different thicknesses, shapes and accuracy grades according to customers' assembly requirements, and support customization of special-shaped shims with holes and slots. Our technical team will optimize the processing process for customers' accuracy requirements. The sample development cycle is 20-30 days, and small-batch trial production is supported. The products support mixed batch customization of different specifications and different precision to meet customers' multi-scenario precision assembly needs.

We implement strict precision control standards for precision alumina ceramic shims. During the processing, three inspection procedures are implemented: first piece inspection, patrol inspection and final inspection. High-precision micrometers, flatness testers and other equipment are used to detect thickness, parallelism and surface quality. 100% full inspection is carried out before packaging to ensure that all products meet customers' accuracy requirements. We support inspection by third-party professional institutions, and the products come with a one-year warranty. Non-artificial processing accuracy problems can be returned or replaced, and we guarantee customers' precision assembly needs with strict quality control.

We provide perfect after-sales service for all precision alumina ceramic shims. Real-time schedule updates and sample accuracy confirmation can be provided during order production. The products come with a one-year warranty. If non-artificial accuracy exceeding standard, cracking and other quality problems occur within the warranty period, we can negotiate return or replacement. If the goods are damaged during transportation, we promise replacement for damaged goods and arrange reissue as soon as possible. After-sales problems are responded quickly, providing customers with a worry-free one-stop precision ceramic procurement service.
