In the machinery industry or automation industry, CAD, CAE, and CAM complement each other. Design with CAD and then manufacture with CAM. CAD is the design process using computer technology, CAE is the use of computer simulation to analyze physical problems, and CAM is the use of computers and computer software to control machines for manufacturing, usually suitable for mass-produced parts.

Hydraulic presses can be used for compaction, assembly, pressing, forming, embossing and stretching. Hydraulic presses can be used for compaction in the cosmetics industry, assembly in the automotive industry, molding of electronic products, and stamping in the home appliance industry.
