2), injection moulding: above-mentioned composite material is formed blank by injection machine by mold injects, and its technical conditions are: mold temperature is controlled at 35 ℃-45 ℃, injection temperature: 185 ° in a district, 176 ° in two districts, 173 ° in three districts, 163 ° in four districts; Injection pressure 725MPa, injection speed: 65 g/s, inject time: 2s; Cool time: 1s before the storage, 8 ± 3s after the storage;

3), extraction: will inject blank, to put into purity be 99.9% trichloroethylene solvent, and addition is as the criterion to cover blank 10-20mm, is incubated 5-6 hour under 50-60 ℃ temperature;

4), sintering: will extract good injection blank and put into the vacuum sintering furnace sintering:

(1) the injection blank is placed on the alumina ceramic plate, leaves each other certain slit, avoids being pasted together in the sintering process; Avoid directly contacting with graphite boxes or graphite cake;

(2) pass into inert gas shielding in the sintering process, pass into nitrogen when 1-800 ℃ of low-temperature sintering, flow-control passes into argon gas at 5-30pa when 1000-1330 ℃ of high temperature, and flow-control is at 10-30pa;

(3) 1330 ℃ of insulations of sintering temperature arrival are 3 hours, and insulation naturally cools to below 1000 ℃ after finishing, and applying argon gas starts blower fan, and temperature is down to below 80 ℃ and is come out of the stove, and are optic communication Gpon optical-fiber network device.

The present invention owing to do not have actual cut, has saved material; The dimensional accuracy of connector and rough surface all improve greatly, and decisive role is played in the increase in Gpon optical-fiber network device service life, the controlled model at 0. 05mm of dimensional accuracy with in.Follow-up assembling speed efficient improves more than 70%, is better than other manufacture method.
