With the inner diameter than the outer diameter of the spool and the clear width parameters used wire rope spool is usually 1:0.4:0.6. Finished with a spool of wire rope is greater, according to the thickness of the rope, wooden spool, iron and wooden wheels, steel spool. Large wooden wheel wooden wheel or iron used maximum outside diameter of the rope up 6m. Semi-finished steel spool wire is usually used for the outer diameter of the large, clear width smaller. Spool capacity V can be calculated as follows: V = B (D2-d2) × 0.7854 × 7.85K; where V is the capacity of the word wheel, g; B is the word round clear width, cm; D is spool outer diameter, cm; d is the inside diameter spool, cm; density coefficient K is wire wrapped. Spool features: Steel Spool: The reinforced with thick welded with NTC, YA-40, etc., and machined balancing test, high strength, high stiffness, high speed retractable cord flatness good . Plastic spool: plastic injection molding plastic cable tray dedicated, high precision products, advanced structure, side dense muscle strengthening, with good balance of performance, high strength, acid and alkali resistance and other characteristics, balance accuracy up to 6.3 . Overall structure is plastic, metal supporting combined to ensure the shaft hole requirements and conductive properties, the product can be removable parts for easy maintenance, generally based on the client device requirements, do different intensity precision spool disadvantage is that the retractable cord meters long, due to the large capacity so that the flange deformation. Spool Spool uses fiber optic cables are widely used in the production process of closing, actinomycetes; serial line data communication cable, twisted pair, a cable manufacturing process, such as income, actinomycetes; applicable RF cable, wire and cable Take high-knitting machine, high-twist machine income, actinomycetes, extrusion machine income, actinomycetes, winding machine income, actinomycetes, etc.; steel retractable spool diameter for relatively small primary products, precision high, such as 0.07MM-0.2MM wire. Also suitable for domestic and imported production line speed closing line processes. Strict product quality control precision in the country ahead of similar products. For wire spool wire and cable and wire drawing industry production process, copper, annealing, beam lines, stranding armouring, cabling, etc., in recent years, mainly for the hose wire, spring steel wire, cutting wire and other income actinomycetes use. Anping Department of spools of plastic products factory, founded in 1998, is located in Anping County, Hengshui City, Hebei Province, South Central Industrial Park, has a strong R & D plastic disc, iron shaft production capacity, Hebei Province Quality Supervision and Inspection Department of the seizure unit . Main plastic spools, plastic disc, wheel, ABS spool, high red spools, bobbins, spools, bobbins polypropylene, propylene spools engineering, plastics and other products. http://www.apxianzhou.com/
