"无线电元件厂" can be translated as "Radio Components Factory" or "Radio Element Factory" in English.
"Radio Components Factory" is more commonly used, as "components" typically refers to the individual parts or elements that make up a larger system or device, which aligns well with the concept of a factory producing radio-related parts.
"Radio Element Factory" is also a possible translation, though "element" might be slightly less specific than "components" in this context, as it can sometimes refer to more fundamental or basic units. However, it is still a valid translation depending on the specific context or emphasis.
