Machine and product manufacturing refers to a series of processes that involve processing individual parts from raw materials and assembling them to produce final machines or products. It is a foundational category for all industries, including automotive, aerospace, home appliances, and industrial machinery. Typical processing methods include cutting, grinding, pressing, welding, casting, injection molding, and additive manufacturing for metals and resins. After these parts are processed, assembly, adjustment, and inspection are carried out. High-precision processing technology, efficient production systems, and strict quality control are indispensable. In recent years, smart factory initiatives utilizing IoT and AI have also advanced, aiming to improve productivity, reduce costs, and stabilize quality.
