​Cold Isostatic Pressing (CIP) is a process of filling a mold made of polyurethane or rubber, placing it in a pressure vessel, pressurizing the isostatic pressure at room temperature with a liquid, and sintering the powder molding that is made. This method is used to manufacture relatively simple and large-sized products such as cylinders and tubes. Because powder is molded with isostatic pressure, it has the advantage of being constant regardless of its size. It is usually applied to products that are too large to be formed by other processes such as Die Compaction(DP). It is important to design the shape of the rubber mold to manufacture complex parts. Depending on the user's application, additional Hot Isostatic Pressing (HIP) is performed to remove residual pores after the CIP process. This is called CHIP (CIP & HIP) process and is mainly used for manufacturing Titanium alloy (Ti-6Al-4V) parts.

 

With PMsolver/ CIP, a proprietary CAE software, the shrinkage shape and density distribution of the powdered mold during the CIP process can be analyzed. Through the sintering analysis of the CIP compact, it is possible to analyze the uneven sintering shrinkage behavior of the density gradient and the sag deflection of its own weight. Based on the results of CIP molding process and sintering process, we can supply various size and shape parts required by the customer through our mold design and mold making technology. Currently, we use the CIP process to manufacture parts of various materials such as Titanium alloy (Ti-6Al-4V), Tungsten heavy alloy, Tungsten-Copper, Tungsten, Tantalum, Molybdenum and Rhenium alloy.
