A cold isostatic press compresses powdered materials at room temperature, as opposed to a hot isostatic press, which uses high heat to compress materials. Cold isostatic pressing, also referred to as CIP, creates products such as ceramic insulators, refractory nozzles, metal filters and refractory blocks. The compressed materials can include powdered metals, ceramics, carbides and chemicals.
In cold isostatic pressing, the powdered material is placed into a mold, which is then placed into the press' processing chamber. The press pumps a liquid mixture, typically oil and water, into the chamber and pressurizes the liquid. The final result is a product with uniform density. When the mold is free, the process is called wet bag processing, and when the mold is fixed, the process is referred to as dry bag processing. When purchasing a cold isostatic press, consider the following:
1. Buy an industrial cold isostatic press capable of high-volume production for use in a factory or plant.
2. Order a medium-size cold press machinery for small production orders and product experimentation.
3. Purchase compact cold isostatic presses for laboratory use.
Purchase a cold isostatic press machine for high-volume productionAn industrial cold isostatic press found in a factory or plant typically needs to turn out a large daily volume of production. Cold isostatic press machines designed for high-volume production must run through thousands of cycles without requiring repair. This type of cold isostatic press varies in size from several feet to several stories tall.
Order medium-size cold press machineryMedium-size cold isostatic presses are ideal for companies that don't require mass production. Mid-sized cold press machinery is also used for pilot production. A pilot production cold isostatic press allows companies to experiment with their products without producing a large quantity.
Buy cold press equipment for laboratory useLaboratory cold isostatic presses are significantly smaller than their industrial counterparts. Laboratory presses are compact and many models have wheels for easy transportation. This type of isostatic press is typically housed in a cabinet to provide a uniform, sleek look in the lab.
- Cold isostatic pressing applications often require additional processing. After a metal or ceramic powder product comes out of the press, sintering heats the product below its melting point so particles adhere to each other.
