1. Quality of raw materials
The quality of raw materials is the basic factor that affects the production accuracy of Special-Shaped Ceramic Structural Parts. The purity, particle size and distribution of ceramic materials will have an important impact on the accuracy of the final product. If the raw materials contain impurities, they may cause local deformation or generate defects such as bubbles during the firing process, thereby reducing production accuracy. In addition, uneven particle size may lead to uneven shrinkage during molding, affecting dimensional accuracy. For example, coarser-grained parts may shrink at a different rate than finer-grained parts, causing deformation of the structural part.
2. Molding process
Different molding processes have a significant impact on the accuracy of Special-Shaped Ceramic Structural Parts. For example, injection molding can achieve high dimensional accuracy, but has higher requirements on molds. Dry pressing molding is relatively simple, but the accuracy may be slightly lower. During the molding process, the uniformity of pressure, the accuracy of the mold, and the control of molding parameters are all crucial. If the pressure is uneven, the density of each part of the structural part will be inconsistent, resulting in varying degrees of shrinkage during the subsequent firing process, affecting accuracy. The accuracy of the mold directly determines the dimensional accuracy of the structural parts. Any wear or deformation of the mold will be reflected on the product.
3. Firing process
Firing is a key link in the production of ceramic structural parts and has a great impact on accuracy. The control of parameters such as firing temperature, heating rate, and holding time is directly related to the final quality and accuracy of structural parts. Temperatures that are too high or too low may cause deformation, cracking or dimensional changes in structural parts. Too fast a heating rate may cause thermal stress and cause cracks in structural parts; insufficient holding time may lead to uneven internal structure of the ceramic, affecting dimensional stability. In addition, the temperature uniformity within the kiln is also an important factor. Uneven temperatures will cause inconsistent shrinkage of various parts of the structural parts, reducing accuracy.
4. Processing technology
For some Special-Shaped Ceramic Structural Parts with high precision requirements, subsequent processing may be required. The choice of processing technology and the level of operation will also affect production accuracy. For example, the selection of cutting tools during machining, control of cutting parameters, and cooling during processing will all affect the dimensional accuracy and surface quality of structural parts. At the same time, the stress generated during the processing may also cause structural parts to deform, and appropriate stress relief measures need to be taken. To sum up, to improve the production accuracy of Special-Shaped Ceramic Structural Parts, strict control and optimization are required from many aspects such as raw materials, molding technology, firing process and processing technology.
