Raw material treatment: mash through 10~20 mesh sieve, and place it in the environment of 23 °C ~ 25 °C for 24h ~ 48h for temperature adjustment.
Molding: pressure 1715 ~ 35MPa, holding time 1 ~ 10min.
Sintering: sintering temperature 360 °C ~ 380 °C, heating rate 30 °C / h, 330 °C for 2h, 370 °C for 3h.
Cooling: The cooling rate is 20 °C / h, and it is slowly cooled at around 330 °C near the melting point of PTFE.
