"组合房屋配件制造" can be translated into English as "manufacturing of prefabricated housing components" or "production of modular housing accessories".
"Prefabricated housing components" refers to parts that are pre-made in a factory and then assembled on-site to form a complete house, which aligns with the concept of "组合房屋" (prefabricated/modular housing).
"Modular housing accessories" emphasizes the accessories or components used in modular housing construction.
Both translations are accurate and can be used depending on the specific context and emphasis.
