2;
(4) PU places: above use machine catching to be placed on by the PU sheet material that step (1) plastic roll completes glass fibre that step (3) evenly scatters;
(5) second time glass fibre is trickled down: adopting cutter for glass fiber cutting glass fibre to be cut to length is 20mm, and uses glass to scatter machine to be trickled down uniformly by glass fibre on the PU that completes in step (4), and the amount of scattering controls at 110 ~ 130g/m
2;
(6) fabric lay: acupuncture nonwoven cloth fabric is laid in step (5) and scatters on the PU sheet material of complete glass fibre by feed mechanism;
(7) compressing: the material after step (6) gained combines by transfer matic automatic delivering mechanism is sent among mould, mould down-pressing forming, obtain shaping after semi-finished product; Wherein mould molding temperature patrix temperature: 100 ~ 120 DEG C, counterdie temperature: 130 ~ 150 DEG C, molding time: 55 ~ 65s, briquetting pressure: 4 ~ 6MPa;
(8) cooling and shaping: the semi-finished product after compressing are carried out normal temperature cooling and shaping, cool time 45 ~ 55s;
(9) high pressure waterjet: the semi-finished product that step (8) cooling and shaping is crossed are carried out high pressure waterjet, cutting hydraulic pressure: 40000 ~ 50000psi, cutting air pressure: 4.0 ~ 6.0kg/cm
2;
(10) check: after inspection, vanning warehouse-in, obtains the ceiling that product scatters glass fibre.
Described glass fibre is the glass fiber of diameter 0.4-0.6mm.
Step (1) described immersion non-woven fabrics base fabric grammes per square metre is 35-60g/m
