What is significant about low-pressure ceramic injection molding? Wouldn higher pressure be better?
Ceramic injection molding in general is useful for making intricate parts with complex features because the details are put in the mold, also known as the tooling. Pins and mandrels can be put in the tooling to make holes in the parts, eliminating the need to drill them in the green state like other processes require, translating into major cost savings from ease of production. Threads can be formed easily using this technique, whereas the only other method is by machining them into the ceramic part, which is again costly. High pressure ceramic injection molding tools must be made of heavy duty materials, like carbide steel, which is expensive compared to the aluminum tooling Ceramco uses. And most importantly, the pressure we use results in uniform packing of ceramic material in the tool, which is desirable to control shrinkage variance across dimensions when the parts are fired.
