PTFE Two-Side Pressing Necessity
Problem Phenomenon
PTFE single-side pressed products have uneven density, two-side pressing improves it but requires equipment modification investment.
Cause Analysis
Single-side pressing pressure distribution decays along thickness; two-side pressing improves uniformity; equipment structure limitation; cost and quality balance.; When troubleshooting on site, verify item by item according to this mechanism, avoiding blind machine adjustment based only on experience
Solution
①Adopt two-side pressing for critical products; ②Evaluate and modify equipment structure; ③Density uniformity detection and verification; ④Quality requirements drive decisions.; After adjustment, continuously sample to verify the effect, confirm stability before resuming mass production
Key Takeaway
PTFE two-side pressing is the structural solution for uniformity; equipment investment exchanges for quality improvement; detection data supports decisions.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
