Machines and mechanical appliances; cold isostatic presses

HS v2022 Code: 847983

About machines and mechanical appliances; cold isostatic presses

HS code 847983 covers a range of machines and mechanical appliances used in various industrial processes, with a focus on cold isostatic presses. These specialized machines play a crucial role in the manufacturing of advanced materials, components, and products across a diverse array of industries, including aerospace, automotive, and electronics. The demand for high-performance, precision-engineered parts has driven the growth of this industry, making it an integral part of the broader global economy.

Production process

Cold isostatic presses utilize high-pressure fluid to compact and consolidate powdered materials, such as ceramics, metals, and composites, into dense, near-net-shape parts. This process involves loading the powdered material into a flexible mold, which is then submerged in a pressurized fluid chamber. The high pressure applied evenly from all sides compacts the material, resulting in a uniform, defect-free part that often requires minimal post-processing.

Production inputs

The production of cold isostatic presses and related machines relies on a range of specialized inputs, including high-strength alloys for the press structure, advanced hydraulic and control systems, and precision-engineered components. Additionally, the machines themselves require significant investments in research and development, as well as skilled labor to design, manufacture, and maintain these complex systems.

Production outputs

The primary output of HS code 847983 is the cold isostatic press and related machines, which are then utilized by a wide range of industries to produce advanced materials and components. These outputs may be consumed by industries such as 871000 Optical, photographic, cinematographic, measuring, checking, precision, medical or surgical instruments and apparatus; parts and accessories thereof, 840000 Nuclear reactors, boilers, machinery and mechanical appliances; parts thereof, and 870000 Vehicles other than railway or tramway rolling stock, and parts and accessories thereof.
