Topsmelt graphite molds are made from 99.9% pure fine-grain graphite with low ash content to prevent metal contamination.
They offer excellent thermal conductivity, high temperature resistance, and strong corrosion resistance. Available in various shapes and multi-cavity designs, these molds enable fast, energy-efficient casting and easy ingot removal.
Compared to silicon carbide crucibles, they provide superior durability and thermal stability. Ideal for precious metal casting in foundries, jewelry making, and refining industries.

Parameters

Features & Benefits

Application

· Ultra-Pure Material: Made from 99.9% pure, fine-grain, high-density graphite with <0.1% ash to avoid metal contamination.

· High Temperature Resistance: Withstands up to 1600°C and frequent heating/cooling without cracking or deformation.

· Excellent Thermal Performance: Offers superior thermal conductivity and shock resistance.

· Chemical Resistance: Resists corrosion from acids and alkalis during casting and refining.

· Smooth, Non-Stick Finish: Cavity surface allows easy release of gold, silver, copper, and aluminum without sticking.

· Self-Lubricating & Durable: Reduces wear and increases mold lifespan, even in high-volume use.

· Customizable Options: Available in multiple shapes, sizes, and multi-cavity configurations.

· Better Than Alternatives: Outperforms silicon carbide molds with better machinability, lower porosity, and minimal thermal distortion.

· Cost-Effective: Ideal for jewelers, metal refineries, foundries, and torch melting due to long service life and versatility.
