What are the factors that affect the stability of ceramic molds?

Nov 30, 2018

Some molds are obviously good at the time of testing, but once they are put into use in the production line, they often have various problems, which cannot meet the production requirements or technical requirements of the products, resulting in abnormal shutdown of the production line, etc., which brings many instability factors. Ceramic molds often have similar problems, so how do you improve the stability of ceramic molds?

For the design and manufacture of ceramic molds, the experience and skills of the designers play a key role, and the design is reasonable or not, only need to pass the test can be confirmed. But the test model is not one time, but it can be completed by multiple trials and repeated modifications.

It is understood that the stability of ceramic molds and the use of materials, the strength requirements of mold structural parts, the stability of stamping material properties, the fluctuation characteristics of material thickness, the range of material variation, the range of blank holder force and the choice of lubricant And many other factors are related.

In the ceramic stamping process, each material has its own chemical composition, mechanical properties and characteristic values closely related to the stamping properties, the performance of the stamping material is unstable, the thickness of the stamping material fluctuates, and the change of the stamping material. Not only directly affects the precision and quality of the processing, but even causes damage to the ceramic mold.

It can be seen from the above that in the formulation of the ceramic mold design, the influence of various factors must be considered, and the tensile ribs are arranged according to the range of the blanking force and the form of the tensile ribs is determined, so that the deformation regions are deformed as needed to be completed.
