In modern construction industry, concrete bricks, as a basic building material, directly affect construction safety and project efficiency in terms of production quality. Traditional concrete brick production relies on manual operation and experience-based judgment, resulting in problems such as large quality fluctuations, significant raw material waste, and low production efficiency. Today, with the deep application of PLC (Programmable Logic Controller) technology, concrete brick machines have achieved a leap from "extensive manufacturing" to "precision intelligent manufacturing." This article will delve into how PLC technology, through precise and intelligent control, firmly grasps every aspect of concrete brick production.
