1. Determine stamping materials: PTFE has high wear resistance and chemical stability, but different materials need to be selected according to specific applications. In the selection, thickness and hardness should also be considered.
2. Drawing the die drawing: Drawing the stamping die drawing according to the size and shape of the product, and determining its geometric parameters and proportions.
3. Design the blanking process: When designing the die, the blanking mode and angle should be determined according to the physical characteristics of the material and the blanking depth.
4. Adjust the gap of the stamping die: according to the hardness and characteristics of the material, make appropriate adjustments to the blanking die, including embedding a pressure plate above or below the die and adjusting the position of the die support point to achieve the best die gap state.
5. Carry out blanking test: after the die gap is adjusted, carry out blanking test, and adjust the size and position of the die gap according to the results until the required size and quality requirements are met.
