Plastic Spools Testing Instruments

A spool in its most basic form is simply a cylinder around which a flexible material can be wound to make it more manageable.  Usually, flanges are added to each end of the cylinder to further contain the material, and in most cases, there is some provision for a central axis around which the spool may rotate.  The surface upon which the material is wound, the barrel, may be considerably larger than the axis or arbour of the spool, much as the rim of a wheel exceeds the hub. Applications for plastic spools are coaxial cable, speaker wire, THHN wire, CATV wire, hose, tubing, chain, rope, and fabrics. A spool designed to accommodate fishing line; it was being manufactured in two pieces. A polystyrene barrel and a flange were moulded separately and glued together.  Holes in each flange provided for an arbour through the centre. Manufacturers test the quality of plastic spools using Plastic Spools testing instruments to ensure that the product can be used efficiently.
