There are so many different ones that it can’t be the same company.
In: Engineering
Generally, no. They are not the same company. Each industry has other companies that support them. For specialized equipment, there are usually a few companies in any industry. For customized equipment, there will be system integrators or factory automation companies that will design and build equipment to specifications.
Even in this case, many sub components are bought off a catalog. So there are companies that make a variety of extrusions, motors, fasteners, drive systems, control systems etc. So the equipment designer translates specifications into a preliminary design and purchases various subcomponents to assemble (sort of like a very sophisticated LEGO).
Of course there are specializations. Some company might focus on food industry equipment, electronic manufacturing, heavy industry, metal forming, plastic molding etc. But you are right, it isn’t one company.
