A Comprehensive Guide to Hydrostatic Extrusion Process, Technology and Applications
Exploring the Basics of Hydrostatic Extrusion Process
Hydrostatic extrusion is a metal forming process that uses high pressure fluid to shape and form metals into desired shapes. It is used in various industries such as aerospace, automotive, medical, and electronics. The hydrostatic extrusion process can be used to produce complex shapes with a high degree of accuracy. It also offers many advantages over traditional metal forming processes such as greater control over the material’s properties and better surface finish.
The hydrostatic extrusion process is based on the principle of fluid mechanics, where a high-pressure liquid is forced into the die and expelled through a nozzle. As the gas enters the die it forms a cavity that expands dramatically as it reaches its target shape. This happens because in hydrostatic extrusion, pressure builds to produce cavities inside an object that are pulled further apart with each successive layer of extruded material. There are three main types of hydrostatic extrusions: conveying, transporting, and jetting. These processes differ mainly in how they drive pressure into and out of their respective cavities.
Conveying hydrostatic extrusion is used in situations where the piggyback (or “on-demand”) process is not well suited, such as when large volumes of material need to be produced in a continuous fashion. It involves filling a die with a fluid and using pressure to force it upward out of the die, typically through an orifice that forms the end of a nozzle. Conveying also allows for “non-wetting” methods of material transport, which are useful when adjacent surfaces need to remain dry and no contact is desired between them and anything else in the system.
Transporting hydrostatic extrusion is used to transport material from point A to point B. It’s typically used in the injection molding of plastics and rubber. The process starts with a bed of granulated material, which is forced through an orifice at the end of a nozzle into a plastic melt pool that has been heated by an appropriately designed heat source. The molten plastic is then forced out through another nozzle, also at the end of a nozzle, and deposited onto the substrate that is to be formed.
Jetting hydrostatic extrusion is similar to transporting hydrostatic extrusion but instead of being forced through a nozzle, the molten plastic is ejected from the nozzle and deposited on a substrate using jets of hot fluid instead of a nozzle.
Overview of Hydrostatic Extrusion Technology and its Benefits
Hydrostatic extrusion is a metal forming technique that uses high-pressure liquid to form metal parts. It is a cost-effective and efficient way to extrude metal, and it offers several advantages over traditional methods of metal forming.
Hydrostatic extrusion provides greater control over the shape of the final product, as well as increased strength and accuracy. It also allows for more complex shapes to be formed with fewer steps than traditional techniques. Additionally, hydrostatic extrusion can be used with a variety of metals, including aluminum, stainless steel, titanium, and copper alloys.
The benefits of hydrostatic extrusion make it an attractive option for many industrial applications. From automotive components to aerospace parts, hydrostatic extrusion provides an effective way to form complex shapes quickly and accurately.

How does the hydrostatic extrusion process work?
Hydrostatic extrusion is a metal forming process that uses a die and an external pressure source to deform the material into the desired shape. This process is used for both hot and cold working of metals, allowing for complex shapes to be formed with minimal effort. The hydrostatic extrusion process involves the application of an external pressure source, such as a hydraulic cylinder, to push the material through a die in order to create the desired shape. By controlling the pressure applied, it’s possible to achieve precise dimensional accuracy while also reducing scrap rates. Additionally, this process can be used with materials that are difficult to form using other methods such as aluminum alloys and titanium alloys.
