Wet-bag and Dry-bag Isostatic Pressing of Cold Isostatic Pressing

Wet-bag and Dry-bag Isostatic Pressing of Cold Isostatic Pressing

1. Wet bag method isostatic pressure

　　The powder into the plastic bag, directly into the liquid pressure medium, and liquid contact, so called the wet bag method. This method can arbitrarily change the shape and size of the plastic bag set, the product flexibility is great, suitable for small-scale production. Each time to bagging, bag unloading operations, production efficiency is not high, can not be continuous mass production

2. Dry bag method isostatic pressing

Rubber bag first placed in the cylinder, work without taking out the powder into another molding plastic bag, put into the pressurized rubber bag, and the liquid does not come into contact, so called a thousand bags method. This method can be operated continuously, that is, the top cover open, from the hopper to fill the material, and then cover the top cover pressurized into suffer, out of the material, the top cover open. Through the bottom of the top bar to press the blank out from the top side. The operation cycle is short and suitable for batch production, but the product specification is limited because the pressurized plastic die cannot be changed frequently.
