Tool carries out vibration moulding treatment, and corresponding time of vibration is selected according to different mould specifications, finally hangs in locating piece to mould
Fixed position, it is ensured that with the glue time more than time of vibration 20 minutes；
Step d：The solidification demoulding, is first put into internal temperature 70 DEG C~90 by the mould that vibration moulding treatment is completed in step c
DEG C sealing baking oven, it is ensured that in the case of 60 DEG C~80 DEG C of mold temperature, lasting solidification is more than 2 hours, completes curing process
Afterwards, mould is hung in the demoulding area of surfacing, locking device is unclamped, after the external mold 100mm that slowly slings, then lift up rapidly, connect
Release internal model, pipeline is steadily hung out, be finally more than the curing oven maintenance that pipeline is put into 60 DEG C~85 DEG C of internal temperature
24 hours；
Step e：Inspection is modified to solidifying the pipeline after maintenance in step d, to the cut and bubble of liner surface
Repaired etc. defect, the defect such as loose thread, burr and gel piece resin to jacket layer surface is polished.
Need to be mended it is further preferred that in the step a, situations such as corrugation, bubble, the fissure of displacement occurs in film around.
It is further preferred that in the step b, small-sized pressure roller pressure need to be used when the stud or inner corner trim of mould are in laying
