德国Siebe工程公司最近推出一种配备有65mm主挤出和38mm共挤出的新颖挤塑机,电缆厂商能以600m/min的线速度给铜导体和铝导体挤塑0.5～5mm的绝缘,并给较大外径的绞线挤塑高达45mm直径的护套,其最大挤塑速度可达250m/min.挤塑速度控制通过动轮或可预调张力的装置来实现,视产品尺寸而定.小尺寸产品是由组合在冷却槽一起的一个圆形牵引轮牵引的,大尺寸产品则需要一个皮带牵引轮.
Siebe Engineering, Germany, recently introduced a novel extruder equipped with a 65mm main extrusion and a 38mm coextrusion. Cable manufacturers are able to extrude copper conductors and aluminum conductors at 0.5-5mm insulation at a line speed of 600m / min and Extrusion up to 45mm diameter sheath for larger OD stranded wire up to 250m / min. Extrusion speed control is achieved by moving wheels or pre-adjustable tensioning device, depending on product size. Small size products are drawn together by a round traction wheel combined with a cooling tank, while large size products require a belt traction wheel.
