Abstract
A process for once extrusion molding to make a sheath comprises the following steps: preparing materials, to be more specific, preparing thermoplastic rubber TPV and polypropylene PP; extruding, to be more specific, using a main machine and a sub machine, putting the polypropylene PP into the main machine for baking for 2 hours at 80 DEG C, putting the TPV thermoplastic rubber material on the into the sub machine for baking for 2 hours at 80 DEG C, during the production, transferring the polypropylene PP in the main machine to a heating barrel to heat the PP polypropylene to the temperature of 180-190 DEG C, transferring the thermoplastic rubber TPV in the sub machine to a heating barrel to heat the TPV thermoplastic rubber is heated to 160-180 DEG C, after the heating is completed, conveying the two materials into a mold, then conveying the two materials by the mold to a molding die for molding; shaping and cooling to process a solidification shape; and cutting, to be more specific, cutting according to demands for using. The sheath is simpler in structure and easier in quality control.
Description
Technical field
The present invention relates to a kind of sheath manufacture craft of an extrusion molding.
Background technology
At present, or sheath mostly is TPE PP single material is extruded exemplar, single material sheath out, and some is too strong, or too soft, and soft words in the time that rain is blowed in vehicle operating, are easy to occur the problem coming off at rain brush. And intensity is very strong, wear after shell fragment at Frameless windshield wiper, be easy to radian original shell fragment to be changed impact brush rain performance.
Summary of the invention
Its object of the present invention is just to provide a kind of sheath manufacture craft of an extrusion molding, has that jacket structure is more simple, quality is more prone to control.
The technical scheme that realizes above-mentioned purpose and take, comprises step;
1) batching, thermoplastic elastomer TPV and polypropylene PP;
2) extrude, adopt main frame and handset, polypropylene PP is placed on to main frame, toast 2 hours, 80 degree, thermoplastic elastomer TPV material is placed on to handset, toast 2 hours, 80 degree, when production, the polypropylene PP of main frame the inside is sent to thermotank, polypropylene PP temperature is heated to 180-190 degree, and the thermoplastic elastomer TPV of handset the inside is sent to thermotank, and thermoplastic elastomer TPV is heated to 160-180 degree, after having heated, two kinds of material are transported to mould the inside, are transported in mould and shape again by mould;
3) shaping, cooling processing solidification shape;
4) cut, cut according to demand use.
Beneficial effect
Compared with prior art the present invention has the following advantages.
1, one extruding-out process makes sheath produce simplification more, reduces man-made assembly cost, and one-body molded structural entity intensity is stronger simultaneously, and sheath texture is better;
2, jacket structure is integrated, and shaping efficiency is high, and cost is more prone to control, and reduces scrappage.
Brief description of the drawings
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is extruding-out process block diagram of the present invention.
Detailed description of the invention
This process, comprises step;
1) batching, thermoplastic elastomer TPV and polypropylene PP;
2) extrude, adopt main frame and handset, polypropylene PP is placed on to main frame, toast 2 hours, 80 degree, thermoplastic elastomer TPV material is placed on to handset, toast 2 hours, 80 degree, when production, the polypropylene PP of main frame the inside is sent to thermotank, polypropylene PP temperature is heated to 180-190 degree, and the thermoplastic elastomer TPV of handset the inside is sent to thermotank, and thermoplastic elastomer TPV is heated to 160-180 degree, after having heated, two kinds of material are transported to mould the inside, are transported in mould and shape again by mould;
3) shaping, cooling processing solidification shape;
4) cut, cut according to demand use.
Claims (1)
1. a sheath manufacture craft for extrusion molding once, is characterized in that, comprises step;
