JEWELLERY FORMING, PLANNISHING &ROLLINGMILLS


Repairing: Reshaping wedding bands/ring shanks to its original shape whether that be round, square, oval etc. When a customer brings a ring to repair most often it has been distorted in shape due to everyday wear. Depending on the size and shape of the ring place it on the tapered Triblet that matches the shape. Ideally use a mallet to tap the ring shank as this will not mark or indent. We supply a large selection of Mandrels for Rings and Triblets with lots of variant shapes and sizes. All of our range are ground with precision and are made of hardened best quality steel. We also supply a wide range of mallets and hammers to use with these tools. Moreover, we stock a large selection of ring sticks and gauges, please see links below.


Popular ways that our customer’s use Mandrels for Rings and Triblets when repairing or manufacturing…


Manufacturing:


When making a ring first decide which shape you would like the ring to be. Round is most common but other shapes sometimes can be more desirable for varying a collection and favourable for selling.


Sizing too is important; measure the customer’s finger size in advance by using a ring gauge and ring stick to determine the size, many Triblets, Ringsticks and Guages in our range have sizes on already. There are many size systems throughout the world so please use a ring conversion chart (see PDF link below). Ring bands can be made in many different shapes and forms using rolling mills, a variety of shapes can be formed using a rolling mill, draw plates, swage blocks etc. To determine the size of the band it is useful to have a ring stick with millimetre, circumference and diameter sizes (code R31920). For example, place your ring on the triblet and size reads “W” UK size, the band length equates to 65mm in length.


Once you have made your band and annealed it, use Half Round Pliers (P4784) to start forming into a circular shape. Place your band on the Triblet shape you would like to make and tap it with a hammer or mallet; hold the Triblet firm and place the end on bench peg for leverage. Keep turning the triblet around in a circular motion and you will have your ring/ band formed. Using a hammer first makes it easier to bend the band and then finish with a mallet to tighten the shape around the Triblet.


Triblets are widely used to make sheet metal, bezels, collets and mounts. Mounts are metal bands that surround the stone(s). We also have a range of smaller Triblets which are used to make large to small jump rings i
