Solid pins' core function is to ensure stable alignment of mold components through high-precision fitting, preventing product defects caused by displacement during processing. The precision, material selection, and processing technology of these parts directly affect the mold's lifespan and molding quality.
The design parameters of solid pins vary depending on the mold type. For example, automotive molds have extremely high requirements for dimensional consistency, necessitating the use of first-grade quality products; while stamping dies focus more on the pin's impact resistance. They are shipped in three states: precision ground, rough blank, and sandblasted. Users can choose according to their subsequent processing needs: precision ground parts can be directly assembled, rough blank parts require in-house processing, and sandblasted parts are used for surface rust prevention. The batch number management mechanism for model KunYuan-022 facilitates the traceability of production batches and quality data.
