A ‘pencil’ is a cast billet of metal that can be fabricated in to other products. In this example it is rolled down in to ‘square wire’ (see first photo). Once it is a small enough gauge, ‘dies’ will be selected to draw the wire through to give it a round profile and to make any fine gauge adjustments. The finished ’round wire’ product is commonly used as feed for chain machines or in manufacturing of handmade jewellery.
