Precious Metals Casting Lines Mini 150 Vertical

Product Information

WERTLI’s Vertical continuous and semi- continuous casting plants, the Mini 150 V, are designed for precious metals in formats such as strips, rods, tubes, hollows and wires which are used in ­important applica­tions for casting materials for the ­jewellery trade, for the gold- and silver semi-finished product industry and for the electronic industry in:

• Pure gold Au999 and Au9999
• Various gold alloys AuAgCu and others
• Watch maker and jewellery alloys on Au basis
• Pure silver Ag999 and Ag9999
• Silver alloys Ag925Cu to Ag300Cu
• Brazing alloys AgCu and AgZnCu and others
• Alloys for dental application AuPd and others

The equipment design of this category of casters is largely governed by small furnace volumes, typically from 1 – 8 liters. The strand dimensions range up to 140 mm strip width and 60 mm bar or tube diameter. The holding furnaces are equipped with induction heated crucibles – one of WERTLI’s own special designs. Many of these plants are used to melt and cast in the same furnace. Most of these casters are equipped with strand extraction machines with high precision drives with PC CAST 3000 TS control system with data printing, remote servicing link, and travelling shears or travelling saws. Strip casters are often equipped with up-coilers.

Fully enclosed furnaces for vacuum melting and casting under protective atmosphere for the application of special materials, such as dental alloys, are also available.
