‘浇注’ is a compound verb meaning 'to pour (a liquid material) into a mold or container,' especially in industrial, construction, or manufacturing contexts. The first character, 浇 (jiāo), means 'to pour' or 'to water' — often implying controlled flow from above. The second, 注 (zhù), means 'to pour in,' 'to inject,' or 'to infuse,' emphasizing directed entry into a space. Together, they convey the precise, intentional act of filling a cavity or form with molten metal, concrete, resin, or sometimes even liquid fertilizer in agricultural settings.

This term is highly technical and formal, rarely used in everyday speech. It appears frequently in engineering manuals, foundry operations, civil construction documentation, and materials science. While 浇 alone can mean 'to water plants,' adding 注 shifts the meaning toward industrial-scale, controlled pouring — not casual or domestic use. Learners should avoid using it for watering gardens; instead, use 浇水 for that context.
