Start by confirming which process the equipment serves and what parts or materials it handles.

Throughput, batch size, load or processing volume determines the capacity range.

Temperature, pressure, accuracy and cycle time must come from the actual process requirements.

Available electricity, gas or other utilities on site narrow down the applicable models.

Continuous or batch operation, and daily running hours, both affect the selection.

Installation space, transport access, interface positions and environmental requirements need to be confirmed together.
