'Hersteller' (manufacturer) is derived from the verb 'herstellen' (to produce/manufacture). The ending '-er' refers to the person or company that performs the action. 'Herstellen' itself is a separable verb: her + stellen.
Diese Firma stellt hochwertige Möbel her.
This company manufactures high-quality furniture.
If you know 'Hersteller' (manufacturer), you can also easily understand other words in the family: the verb 'herstellen' (to produce) and the noun 'die Herstellung' (production/manufacturing).
Die Herstellung von diesem Auto dauert mehrere Wochen.
The manufacturing of this car takes several weeks.
In the context of products and warranties, certain phrases are very common: 'sich an den Hersteller wenden' (to contact the manufacturer), 'die Angaben des Herstellers beachten' (to follow the manufacturer's instructions), or 'direkt vom Hersteller kaufen' (to buy directly from the manufacturer).
Laut Hersteller soll das Gerät alle zwei Jahre gewartet werden.
According to the manufacturer, the device should be serviced every two years.
brand / mark / stamp
'der Hersteller' and 'die Marke' both belong to the world of products, but they do not mean the same thing. The manufacturer is the person or company that produces a product. The brand is the name or sign under which a product is sold. Learners may confuse the words because many products have a brand name on them, and it is easy to mistake it for the company that manufactures everything itself. If you are asking about production, 'Hersteller' fits. If you are talking about the name, logo, or image of a product, 'Marke' fits.

Auf der Verpackung steht, welcher Hersteller das Gerät produziert hat.
The packaging says which manufacturer produced the device.
