PP - R tube production technology for extrusion molding process, first in the charging hopper of PP - R raw materials by weight into the extruder, the extrusion machine barrel in the heating extrusion mixing, fully plasticizing from extrusion machine die extrusion, into the stereotypes and Taiwan, after the shape of the pipe by the traction machine, by fixed length determination, cut off by the cutting machine, pipe after passing inspection by storage. The corresponding tube is produced by injection molding method. Pipe production process: PP - R raw, vacuum ceiling send material hopper, storing, feeding, extrusion molding, cooling, shaping, drawing, cutting, examining and storing pipe production process: PP - R raw materials, transport material hopper, storing, feeding, heating and melting, extrusion and injection plastic, cooling and molding, die opening, inspection and storage. Machine in the middle of the cylinder at the back of the temperature distribution of pipe die extrusion parameters: (1) the screw speed of 5 ~ 38 R / min (2) barrel temperature distribution of 1 ~ 2 area of 180 to 190 DEG C for 3 ~ 4 200 to 210 DEG C temperature of 200 DEG C traction speed 2 to 20m / min injection parameters: (1) barrel barrel 160 to 170 DEG C machine 200 to 230 DEG C in the front of the drum from 180 to 200 DEG C (2) nozzle 170 to 190 DEG C (3) mold 40 to 80 DEG C PP - R tube production process of defective products, the broken can be re utilized, which will improve the material utilization rate, and can reduce the production cost and improve the economic benefit. |
