Tool Steel (9CrSi): It has high hardness, good heat and corrosion resistance, high memory strength and deformation resistance, is hard and durable, and is very suitable for various mould manufacturing and processing.
Suitable for processing steel, cast iron, copper, aluminum, zinc and other moulds. The moulds are widely used in thread repair and other processing, and can also be installed on the mould frame on the machine tool for use.
High Precision: Adopting standard weight accuracy, clear thread, one-piece mould processing technology, and no burrs.
High Efficiency: Large-capacity chip removal hole design, smooth chip removal, hard tapping threads, and improved processing efficiency.
Accurate Positioning: The locking hole is in the same position as the mould base, and the locking force is strong, stable, and not loose.
