The dipping former as shown in Figure 3 10 that the plurality of nozzles of shape is attached to it shown in use Fig. 4 is made long fiber reinforced thermoplastic resin molding materials.Each of nozzle is of a size of D1=10mm, D2=5mm, D3=15mm, D4=2.2mm, D5=10mm, R (radius of curvature of the crooked tapering of first tapering part)=5mm, L1=2mm, L2=20mm, L3=2mm, L4=6mm, L4/D4=2.7 and its material are brass.About fiber, use the glass fiber bundle that 17 glass fibres are flocked together, described glass fibre is 600 filaments of glass acquisitions of 13.5 μ m by the pack diameter.And acrylic resin is as thermoplastic resin.
The speed of squeezing pull bar shape product is set to 15m/min, and is the N=4 bar with other condition setting, Q=1,747mm
3/ sec, L=1,000mm, S=2,360mm
2And A=1.3.Then, the content ratio of manufacturing glass fibre is the long fiber reinforced thermoplastic resin molding material of 70% (weight).In this manufacture process, around nozzle crowded draw, the fracture frequency of the breaks of rod-shaped articles each nozzle that is counted and is converted into a day in (24 hours).By the filaments of glass that comprises glass fibre partly the fracture that is accumulated in the glass fibre that causes in the nozzle of fracture and grain raising and burr be counted as the fracture of rod-shaped articles.Fracture frequency among the present invention is each nozzle 0.099 time every day.
For relatively, the nozzle (prior art) that uses shape shown in Fig. 5 with top identical condition under and in identical method the breaks of counting rod-shaped articles.Although nozzle 60 has shoulder 68, it has substantial cylindrical, has the hole 65 that penetrates it, and the cross section in described hole is circular.Hole 65 has tapering part 66 and parallel or straight part 67.Each of nozzle 60 is of a size of D6=9mm, D7=2.2mm, D8=15mm, D9=10mm, L6=25mm, L7=5mm.The fracture frequency of rod-shaped articles in the prior art is each nozzle 0.77 time every day.
As mentioned above, the fracture frequency of rod-shaped articles of the present invention is far smaller than fracture frequency of the prior art.So the productivity ratio that strengthens thermoplastic resin molding material at dipping former medium-length fibre of the present invention is higher.
The above description of the preferred embodiments of the present invention is provided for illustration and purpose of description.It is not to be intended to be exhaustive or limit the invention to disclosed exact form.It is possible significantly revising or change according to above instruction.Selecting and describing embodiment is for the best illustration of principle of the present invention and application in practice thereof is provided, allow thus those of ordinary skill in the art in various embodiments and be suitable for expecting special-purpose various modifications and utilize the present invention.All such modifications and variations are in the scope of being determined by accessory claim of the present invention when understanding according to the extension that gives claim by rights, legally and equitably.Accompanying drawing and preferred embodiment are not and be not to be intended to by any way at it its ordinary meaning of restriction claim in the proper and extensive interpretation.
