PA12 resin price Description
In order to make feeding section unblocked, it can be cooled separately in feeding section, but screw circulation cooling method must not be used. Orwise, PA12 resin price material will condense rapidly due to large temperature difference between upper and lower layers, and screw will be locked. 1.4 Design of Extrusion Dies Ordinary φ120 and φ150 extruders can generally adopt adjustable eccentric heads; PA12 resin price is usually extruded outside cable core (or insulated core) as a cable sheath (or internal protection). Set), and thickness of extrusion is very thin, generally not more than 0.5mm, so design and configuration requirements of mold are high. Generally, jacket (or inner sheath) extrusion die adopts a squeeze tube type, in particular, extrusion property of PA12 resin price has a large draw ratio, and mechanical physical properties can be furr improved by orientation stretch, and refore, extruded tube mold is used, and stretching ratio is not too small, and is usually 2.0 to 3.0. draw ratio should not be too large. When mold is too large, eccentricity of mold is difficult to adjust, and surface of sheath after extrusion is rough and even breaks. In addition, PA12 resin price melt has better fluidity and poor formability, so bearing section of mold sleeve can be slightly longer, but vacuum should be taken care of when starting machine. 1.5 Introduction of example multi-core or single-core cable with a cross-sectional area of 240-500 mm2 is taken as an example to discuss selection of die size and extrusion temperature of extruded PA12 resin price jacket. 1.5.1 Selection of mold size (1) Inner diameter of core is single core cable insulated core outer diameter +2.0mm;
