High Temperature PTFE Gasket

PTFE Gasket:

Manufacturing process: 1) raw material preparation; ingredients: pure F4 products, raw material F4 fine resin, mashing, sieving; 2) mold preparation: wipe with alcohol, there is no rust and attachment in the die; 3) weighing, According to the formula g = PV (where G is the feeding amount, P is the density of the pre product (2.18g / cm3) V is the product volume), weigh out the weight; 4) feeding: evenly distribute F4 resin on the whole pressing surface; 5) pre forming (pressing): calculate the gauge pressure of the press according to the formula, and set the gauge pressure of the press. Press; 6) demoulding trimming: take out the semi-finished product from the mold and trim its surface to make its surface flat and edge neat. Preparation for molding; 7) sintering: slowly put the semi-finished products into the sintering furnace, put them into a suitable number, heat up for about one hour to 390 degrees, and then conduct heat preservation for another hour, and then start to cool down after molding, about four hours later, arrive at the indoor temperature, and then the finished products are discharged and finished.
