Start with the filling method
Low pressure casting uses applied pressure to move molten metal into the mold. Gravity casting relies on gravity for filling. These are different filling approaches; the name of the process alone does not confirm which route fits a particular component.
Review the component as a whole
Bring the drawing revision, application, material specification, critical dimensions, machining, surface requirements and inspection records into the same discussion. Mark open questions rather than assuming a standard specification.
Keep casting and machining connected
A casting may also need CNC machining for mating faces, bores and threads. Datums and dimensional requirements should be shown on the drawing so the two stages can be discussed as one project.
Confirm the next step
An initial review is not a confirmed manufacturing specification or quotation. Ask which information is still needed, what is included in the proposed scope and how samples and inspection will be agreed.
