Classification by Machining Process
Precision Stamped Parts: Formed in one step using cold stamping and progressive die processes. Suitable for machining irregularly shaped parts such as gears and bushings. Widely used in electronic springs, hardware shielding covers, and new energy power battery components. This is the most widely used type of precision metal part in consumer electronics and automotive industries.
Precision Turned Parts: Machined using Swiss-type lathes and precision automatic lathes. Accuracy can reach 0.05mm~0.1mm. Materials include stainless steel, free-machining steel, and copper alloys. Primarily used for non-standard fasteners, watch movement parts, and instrument connectors-small, complex parts.
Precision Casting Parts: Includes investment casting and ceramic mold casting. A near-net-shape process, castings can be used directly without secondary machining. Capable of producing complex, high-temperature resistant special parts. Commonly used in aerospace and high-end machinery for irregularly shaped structural parts.
