Product Description

Our graphite molds for gold bar are made of high quality graphite that are specially made for casting precious metal ingots in a vacuum gold bar casting machine. The graphite molds for gold bar come in different sizes and forms. There are four in one bar molds, two in one bar molds and single bar molds. It can also include Includes a variety of mold cavities, all within one convenient mold! We offer custom engraving and sizes are available upon request! The bar molds are suitable for all gold ingot casting capacities; small, medium and large, ranging from 100g to 1kg.

Our graphite molds for gold bar has a very smooth finish that makes precious metal ingots to have smooth and clean appearance. The graphite mold is used for making ingots of gold, silver, copper, platinum and other metals. 

 

Gold bar mold's durability makes them highly recommended and usable for casting ingots in precious metal foundries and other mechanical industries. The gold bar molds are highly durable and cost effective for all industries.

Additional Features & Specifications:
• Smooth cavity finish.
• Designed for easy ingot removal with 10° tapered sides.
• Excellent thermal resistance and corrosion resistance
• Good thermal conductivity
• Good resistance to acidity and alkalinity
• Impact resistant
• Energy saving
• Ingots are easily removable after casting

All of our graphite crucibles, dies and ingot molds can be customized:
