1. （Punch）

• Function: The core component for stamping and forming, responsible for applying pressure to sheet metal to create desired shapes (e.g., holes, grooves, or profiles) in easy-open lid production.

• Features: Made of high-hardness tungsten steel (HRC 60-62) with a precision grinding finish; surface roughness ≤ Ra 0.2μm; dimensional tolerance controlled within ±0.003mm to ensure consistent stamping quality.

• Application: Key part for punching easy-open lid pull-tab holes and score lines.

2. （Die Cavity）

• Function: Works with the punch to form the sheet metal, providing a matching cavity for the material to deform and take shape.

• Features: Adopts modular design for easy replacement; inner wall undergoes nitriding treatment (nitride layer thickness 5-8μm) to enhance wear resistance; service life ≥ 500,000 stamping cycles.

• Application: Used for shaping the curved edge and sealant groove of easy-open lids.

3. （Guide Post）

• Function: Ensures precise alignment between the upper and lower mold bases, preventing offset during stamping to avoid defective products.

• Features: High-precision linear motion component; coaxiality tolerance ≤ 0.002mm; surface coated with wear-resistant PTFE to reduce friction and extend maintenance intervals.

• Application: Essential for maintaining mold accuracy in high-speed easy-open lid production lines (up to 300 strokes per minute).

4. （Stripper Plate）

• Function: Separates the stamped sheet metal from the punch after the stamping process, ensuring smooth material feeding and continuous production.

• Features: Equipped with high-elasticity polyurethane springs for stable stripping force; integrated with proximity sensors to detect material jams in real time.

• Application: Prevents sheet metal sticking to the punch in easy-open lid blanking and forming processes.

5. （Locating Pin）

• Function: Positions the sheet metal accurately before stamping, ensuring consistent placement of each workpiece to avoid dimensional deviations.

• Features: Cylindrical pin with a tapered guide tip for easy material insertion; dimensional tolerance ±0.002mm; corrosion-resistant chrome plating (plating thickness 0.005-0.01mm).

• Application: Used to align the aluminum sheet before stamping easy-open lid pull-tabs.

6. （Spring）

• Function: Provides elastic force for components like the stripper plate and ejector pin, ensuring reset after each stamping cycle.

• Features: Made of high-carbon steel (SWOSC-V) with heat treatment; fatigue life ≥ 1 million cycles; stable elastic force under high-frequency compression (300 times/min).

• Application: Powers the stripper plate’s reset and the ejector pin’s material-ejecting action.

7. （Ejector Pin）

• Function: Ejects the formed workpiece from the die cavity after stamping, ensuring smooth workpiece discharge.

• Features: Tungsten steel material with a polished tip; diameter tolerance ±0.002mm; equipped with a buffer structure to avoid scratching the workpiece surface.

• Application: Ejects finished easy-open lids from the die cavity onto the conveyor belt.
