Welcome back friends, we now see the subject of manufacturing process in which we see the subtype, subtopic processing of polymers. In this we will see the topic covered 12 2-zoned filament welding winding and injection molding. 12 2-zoned is a composite synthetic process where a constant cross section and production rate is obtained. In this process the fibers are pulled through a heated die while passing through the die a constant pressure is applied resulting in a resin melting and its impregnation into a fibrous reinforcement. 12 2-zoned is a continuous process used to manufacture fiber reinforced polymer composite profiles with a constant cross section. A composite is a composition material typically considering the considering consisting of polymers and polymers. Reinforce with glass carbon are made fibers or combinations thereof. It is shown in Pizzer which has guide plate fibers that are made in the same way. The resin bath, performer for forming and curing die, pulling system cut off saw is shown in the figure. Then also, the resin bath, performer for forming and curing die, pulling system cut off saw is shown in the figure. Then also, the tree is given continuous revolving is given, other reinforcement guide plates, resin bath, heated die, pulling force and cutter is given in the figure. Anvantages of curl-tusion, very fast economic resin content can be accurately controlled structural properties of laminated are very good. This event is of pul-tusion, high cost, mold cost, limited to production of products with single cross sectional shape, load transverse strength filament winding. Pul-tusion is an automated open molding process that uses erotating mantle as the mold, the male mold configuration produces a finish inner surface and the laminated surface on the top outer outside diameter of the product. So, modern products created using composite filament winding, golf club shafts, automobile drive shafts, sailboard marks, over coars and paddles, or small boards, small aircraft, huge legs, legs, spacecraft structure, structures, the surfaces like fire fighter oxygen bottles, filament winding, it is shown in the figure. It shows that fiber pulls from dry device, tension device, the payout eye, transverse resin both resin bath, mantle rotation. Rotation is given to the mantle and the product is finished. Also, in this figure we have seen the three continuous growing separator, poridore, resin bath, knee prologue and rotating and rotating mantle and the advantages of filament winding winding, resin contents, the content is controlled by nips or dyes. The process can be very fast, economical, complex fiber, patterns can be attained for better glows, bearing of the structure and disadvantage is low viscosity. Cost of large component is high, external surface, not smoothly finished, injection molding. Injection molding is the method to obtain molded products by injecting plastic materials molten by heat into a mold and then cooling and solidifying them. The method is suitable for the mass production of products with complicated stage and takes a large part in the area of plastic processing, major stages of injection molding. Making a mold, install the mold in a specific machine, the injection molding machine inject the softened plastic materials under high pressure under the effect of heat in the mold, cooling of the hole through, cooling channels within the mold eject the part, repeat the, with the next part injection molding. It is shown in figure. Crosshead is given, clamping unit, toggle type is also given, mold is given, tie bar is given, injector machine, injector mechanism is given, black post, flow cylinder, walls, heater, hopper, screw, mortar injection unit is given, this is shown in figure as a 3D model, advantages, faster production, design flexibility, higher output production, low labor cost, good color control, good dimensional control, disadvantages, high cooling cost and machinery cost, part design restrictions, applications, automotive components, electronic components and toys. These are the polymer processing, thank you.
